Why have standards when you can have double standards?

Posted on by

Plant-based juice (reduced)Apparently it’s World Vegan Month (WVM). This may come as a surprise to those who have adopted vegan diets, not out of choice, but simply because they cannot afford or have access to animal products, but I digress. According to the Vegan Society,  WVM is a time to recognise how far the vegan movement has come, to highlight how accessible and beneficial a vegan lifestyle can be and to encourage the vegan-curious to adopt veganism by sharing advice, recipes and ideas. Judging by the preponderance of plant-based “mylk” in the reduced section of my local supermarket (pic), it may not be entirely successful – indeed, recent media coverage has been anything but celebratory.

First, the news that an editor of Waitrose magazine resigned after making very ill-advised comments via email, not simply to a friend or colleague, but to a vegan journalist who then posted the comments to Twitter. Cue predictable outrage and headlines including: “Waitrose magazine editor causes outrage after he suggests ‘killing vegans.’” In the editor’s defence, he actually suggested (apparently as a joke): “How about a series on killing vegans, one by one. Ways to trap them? How to interrogate them properly? Expose their hypocrisy? Force-feed them meat? Make them eat steak and drink red wine?” Misguided? Yes. Silly? Yes. Actually threatening death or bodily harm? No.

By contrast, a farm shop in Devon that advertised their Christmas turkeys had “murderer” and “go vegan” sprayed across their windows, and received anonymous phone calls where they were asked: “How would you like it if I cut you up and put you on the counter?” and “You should be the ones being killed because your life is worth less than that of the innocent animals which you are murdering.”

The most-common response from vegans to these threats? “That’s simply a sub-section of activists, we don’t support threats or abuse.” While I have no doubt that the average pleasant, law-abiding, non-activist vegan would not endorse or carry out such activities, it highlights an interesting double standard. Many who protest against livestock farming use photos of normal husbandry practices labelled with misleading captions – for example, that is not a captive bolt in the photo below, it’s a dehorning tool – it’s as lethal to a calf as an iPhone or cup of coffee.

Moreover, many posts on social media include information about and/or photos/video clips of bad practices or animal cruelty, often years-old or captured in other countries. When farmers point out that on their farm (or indeed, in their entire country or region), practice X does not occur and that they would never condone animal cruelty, the response is: “Some farmers do, therefore you’re all guilty.”

It’s not possible to have your milk and drink it – disclaiming responsibility for activist activities performed in the name of veganism, yet suggesting that all farmers are responsible for the bad practices demonstrated by a few bad apples, is an extreme double standard. There is no place in livestock farming for animal abuse or poor welfare and we all have a responsibility to make sure that it does not occur, yet it’s time for the same principle to be applied to activism. Can you really preach peace, love and compassion for animals while ignoring attacks on humans? I’d suggest not.

How to Argue with Vegans – A Cut-Out-and-Keep Chart (new and improved!)

Posted on by

I will never criticise anybody for being vegan, vegetarian, pescetarian, flexitarian or any other diet. Always put popcorn on top of tomato soup (don’t knock it till you’ve tried it…) or fancy a pickled onion and herring cocktail for breakfast? No problem, we’re all entitled to choose the foods that suit our lifestyle.

Although I often promote dairy and meat production, I would never demand that somebody eat a steak or a cheese sandwich – it’s entirely their choice. Yet, with the rise of social media, a growing proportion of people feel entitled to criticise other’s diets, to the point where logic, science and civilised debate are lost in a rampant outpouring of emotive language and misinformation.

Having been engaged in countless online conversations with vegans, it appears that a handbook must exist, as the debate follows an identical pattern. The same inevitably tedious questions posed and claims made, often without any regard for the responses from the other side. In case you decide to argue with a vegan, I therefore present you with my updated handy flow-chart for how the conversation may go. Note that I do not intend to mock and I’m sure that there are many vegans who are both eloquent and well-informed, but, if you are vegan, perhaps consider whether you always rely on these rather asinine claims, without broadening your argument?

Screen Shot 2017-11-13 at 17.39.03For example, is suggesting that we shouldn’t drink milk past-weaning because other animals do not, either upheld by science (no, it’s not) or a sensible criticism? After all, humans also wear expensive anoraks, use iPads and write books on the intricacies of rugby – should we forgo these activities because they are exclusive to homo sapiens?

It’s absolutely true that some people cannot digest lactose. Furthermore, a proportion of the population have adverse reactions to gluten, some people have life-threatening allergies to strawberries, others break out in a rash after eating scallops. Does that mean that we should all remove these foods from our diets in somewhat misguided sympathy? No.

It should be obvious that using overly emotive language or suggesting that farmers are guilty of obscene acts with farm animals detracts from your message. Nobody takes Boris Johnson seriously when he makes outrageous claims or shows utter disregard for cultural and social norms – why should anybody embrace a lifestyle choice where the messaging suggests that eating cheese is equivalent to drinking breastmilk or implies that artificial insemination of cattle is morally, physically and emotionally equivalent to serious sexual assault in humans?

I don’t converse with vegans in order to try and change their opinions, but to show all the others who are listening in the background that it’s possible to have congenial, polite and scientific debate on these topics without resorting to insults, foul language or suggestions that the opponent should “get their fist out of a cow’s rectum”.

I stopped engaging in a recent Twitter conversation when a vegan posted a screenshot of my Twitter bio and claimed that, as a breast cancer survivor, I was foolish to consume a “hormone cocktail” (milk). I may be biased, but using cancer, still a life sentence for far too many, as a tool for trying to promote veganism, utterly lacks the human compassion that the same person claimed should be extended to farm animals.

Screen Shot 2017-11-13 at 14.45.04

Let’s get real. If artificial insemination, housing cattle, removing the calf from the cow and all the other practices that are apparently abhorrent to vegans were outlawed, would those opposed to meat and dairy production on the grounds of exploitation and slaughter be appeased? No.

So, here’s the challenge to angry vegans. Blow away the smoke, mirrors and pseudo-animal welfare outrage, and ask the real question: Are you prepared to let animals be killed in order to enjoy meat? If the answer is yes, then move on, there’s nothing for you to tweet about here.

50 Sheds of Grey – Mega Farms and Animal Welfare Are Not Black and White Issues

Posted on by

Further to yesterday’s blog post here, I was asked for my views on this article in the Telegraph by companion animal vet Pete Wedderburn. Given my propensity to use 17 words when three will do (I blame PhD training…) it was easier to blog about it than reply via Twitter.

TelegraphTo be fair to Dr Wedderburn, his article does note the importance of economies of scale and potential for targeted veterinary care on large operations; and it’s absolutely true that we, as consumers, demand affordable food. The average Briton spends only 8.2% of their income on food. Given how much we should value the nutritional advantages provided by meat, milk and eggs for growth, development and health, I have no issue with the suggestion that we should pay more (if needed) for higher welfare animal products.

Yet that’s where the argument gets difficult, and in the case of the Telegraph article, moves away from logic, science and economics towards anthropomorphism, emotion and the supposition that we can assess animal welfare based on human experience. If there was an emotive language quotient for the article, it went up significantly in the anti-mega-farm section.

Unpalatable (pun intended) a truth as it may be, we do not apply to the same standards to animals that we intend to eat (cows, pig, chickens) as to companion animals (it’s somewhat amusing that the Telegraph article was published within the “Pets” section), or indeed to animals that we consider to be pests (rats, mice, insects etc). Do many of us worry about the living conditions of house spiders or wasps, aside how we can kill them when they become a menace? No. Activist groups claim that this is speciesism, but I’d contend that it’s simply a factor of being human. We cannot have our bacon and eat it – if we apply the same standards to pets and farm animals (eliminating the “double standard” cited in the article) then perhaps by extension, just as we wouldn’t tuck into a steak from our pet labrador, we should cease to eat farm animals.

The ultimate irony is that, if asked, none of us would be happy to be killed and eaten. Slaughter is an inevitable truth of meat production, regardless of the conditions in which the animal is reared – if we cannot reconcile ourselves to the fact that we, as humans, would not be happy with that outcome, can we really assume that we can speak for animals’ preferences in any other circumstance?

“Animal welfare is a significant one [issue]: intensively kept farm animals never experience the open air, and never see blue skies” Being outside in the sunshine is undeniably lovely. However, we’re in the midst of the ill-named British “summer”. The rain is driving down and the Hereford cattle in the field I drove past five minutes ago were sheltering under a tree, ironically, voluntarily choosing to be in far closer quarters than cattle housed in a shed. We need to move away from the pervasive but false image of perpetual blue skies and sunshine. Would I personally wish to exist within the human equivalent of a battery cage? Of course not. Yet neither would I wish to be outside in pouring rain and cold wind. It’s all about balance. Do I know what a cow, chicken or pig prefers? No. We need further research to elucidate animal preferences and, *if* required, to amend our farming systems.

“Animal health is another concern: with thousands of animals living so closely together, the risk of rapid spread of contagious disease must be higher.” At face value – true. However, as with so many rhetorical statements, this bears further examination. The risk is higher. Not the incidence, nor the mortality or impact on the animals, the risk. We can have a significant increase in risk that still makes little difference to the likelihood of an event happening. Take, for example, the announcement that processed meat increases the risk of colon cancer by 18%. Immediate media reaction? “Bacon will totally kill you!” Actual change in relative risk for the average person? An increase from 5 people out of every 100 contracting colon cancer, to 6 people out of every 100. Using blanket statements about increased risk, without backing them with any science or relative risk metrics (i.e. the likelihood of an incident actually occurring) is meaningless, yet an effective fear-mongering tool. If any farm (regardless of size) has excellent health plans in place, employs effective veterinary supervision and treatment and has appropriate biosecurity and isolation for sick animals, there is no reason to suggest that disease X will spread unchecked. Why did the UK government mandate for poultry to be housed when the risk of avian influenza was high? Because it’s spread by contact with wild birds and poultry, in precisely the supposedly healthy conditions proposed by the Telegraph article.

The supposition that “…if something does go wrong, it can go wrong on a massive scale, affecting thousands of animals at one time” is again correct – with one significant caveat. Relative risk again comes into play – why would a ventilation system be more likely to fail on a large operation than a small operation? A risk may exist, but again, it’s the relative risk (ignored by the Telegraph article) that is more important. To use a human example, if the power supply fails to a large hospital, we would assume that they would have more back-up systems in place than in a small cottage hospital. Why should Dr Wedderburn assume that large farms do not have operating procedures and practices in place to deal with disaster situations? In the USA last year, 35,000 cattle died during a two-day snowstorm, the majority not housed, but in open fields. Being able to control the environment and feed supply is a major advantage of housed systems – assuming the worst case scenario is business as usual is misleading at best.

Animal welfare is a useful tool with which to bash specific farming operations, because it carries a certain intangibility. What does good animal welfare really mean? How is it assessed? Are healthy animals automatically “happy” or in a good welfare state? Perhaps it’s time to revisit and challenge the rhetoric. Given that high-producing livestock should, by definition, be healthy, does that mean that we can use milk or meat yield as an indicator of welfare? Not necessarily. If we have to reduce the use of critically-important antibiotics, will animal welfare suffer? Not if we use other husbandry measures to prevent the disease from occurring in the first place (see figure below). Is a cow who is genetically programmed to produce 40 kg of milk per day automatically more stressed than one who is only programmed to produce 20 kg of milk? Few people would suggest that a woman capable of producing copious quantities of breast milk is more stressed than one producing a small amount, yet we try to apply this logic to livestock.

Langford CIA decreaseEmotion is a far more effective tool to lead conversations about controversial issues than science – perhaps its time to take the bull by the horns and get in touch with our touchy-feely side to communicate as the activists do. Ultimately we need to reassure consumers that, as with all issues, there’s no ideal or one-size-fits-all farming system, just a million shades (sheds!) of grey.

How Many Vegans Does it Take to Change a Dairy Industry? It Depends How We Look at the Numbers

Posted on by

Jerseys in parlourThe Advertising Standards Authority in the UK have just ruled that it’s permissible for vegan campaigners to use emotive terminology to describe dairy production, on the grounds that the claims made do represent dairy farming methods.  Thus, phrases such as “mothers, still bloody from birth, searched and called frantically for their babies” are sanctioned as legitimate, despite the anthropomorphic language and lack of sound scientific evidence for loss- or grief-type emotions in dairy cows.

Excellent animal welfare should be the cornerstone of every livestock production system, including the non-tangible and therefore difficult to measure emotional side of animal welfare, yet using these types of emotive phrases does not really appear to be advancing the vegan cause. As quoted in the Times article, 540,000 people in Britain enjoy a vegan diet at present, up from 150,000 in 2006.

That’s a considerable number, approximately equal to the population of Manchester (City, not Greater Manchester) or the number of people in the UK who are aged 90+, yet as a percentage of the total British population, less than one percent (0.82% to be exact) choose a vegan diet. Is the proportion increasing? Yes. The equivalent percentage in 2006 was 0.25%, yet even at today’s figures, 99.18% of the British population are non-vegans. Are there any other situations where we would consider than less than 1% of the population to have a significant influence? Possibly not.

Bad news bias factory farm

Given that it takes five pieces of positive information to negate the impact of one piece of negative information, it’s more crucial than ever to get simple, factual, attractive messages out to the general public about dairy farming. Rather than campaigning against emotive activist claims, we need to reach out to the 99.18% of people who have not removed animal products from their diet and reassure them that they’re making appropriate food choices for themselves and their children.

How Now, Old Cow? Do “Slaughter-Free” Dairy Farms Come at an Unsustainable Cost?

Posted on by

As consumers, we’re more like sheep than we’d like to admit – that is, if sheep were tempted to buy food based on “free from” marketing. Gluten-free, fat-free, lactose-free, dairy-free and GMO-free labels are already firmly stamped on many of the foods we buy in shops and restaurants, and are associated with an invisible yet potent, virtuous halo. After all, if a slice of cake is gluten-free, it must be positively healthy.

The latest marketing wheeze appears to be “slaughter-free” dairy production – a 30 cow herd in Rutland, described as a bovine spiritual utopia, where calves are not weaned but run with cows as “grazing partners”; male calves (renamed as ”oxen”) are used for draught power rather than reared as beef; and once cows retire from milking, they are literally put out to pasture rather than being culled.

There’s no doubt that this ticks an entire list of ethical boxes – who doesn’t want to imagine that cows live a happy life browsing the buttercups once they’re too old to produce milk? Yet, given the critical need to produce food sustainably (in terms of economic viability, environmental responsibility and social acceptability), it also leads to a number of questions.

While there may well be a niche market of consumers who are prepared to pay £4.50 per litre for slaughter-free milk; in an era when we primarily choose foods based on price, is this endeavour going to achieve long-term economic sustainability?

Food purchases for EU consumers

The environmental impact of dairy production increases with the proportion of non-producing (dry cows, growing heifers or “retired” cows) in the population – keeping retired cows out on pasture would be expected to add a huge quantity of greenhouse gases to the carbon footprint per litre of milk produced. Carbon footprint and resource use per litre is also negatively correlated with milk production – the low yields associated with this type of hand-milking operation would further add to its environmental impact. How do we, as consumers, balance the relative values of animal welfare and planetary health?

FAO LCA 2

In a system where no cattle are slaughtered, but where cows need to have a calf on a regular basis to produce milk, the herd size will increase exponentially over time. In two, five or ten years time, how will the owners reconcile philosophical arguments against slaughter with the difficulty of supplying enough feed to fulfil the requirements of an ever-expanding herd using a fixed quantity of pasture?

Finally, and most importantly, animal welfare should be the cornerstone of any dairy farm. Euthanasia is upsetting, yet is the only option when animals are too sick or injured to survive. As consumers, we need to take responsibility for the fact that slaughter of both healthy animals (for meat) and sick animals (for humane reasons) is an unavoidable, if unpalatable truth. Just as the recent ban on cattle slaughter for beef in India is going to have negative impacts on food security, economic sustainability and environmental impacts, it’s time that we faced up to the reality of food production and stop thinking that we can have our slaughter-free dairy and eat it!

From The Archers to Antibiotic Resistance – Has BBC Radio 4 Lost the Plot?

Posted on by

ResistanceAfter some excellent commentaries on future food production and Brexit on Farming Today last week, it seems that, not content with domestic violence, miscarriage and admitting women to the Ambridge cricket team (the horror of it!) on The Archers, BBC Radio 4 has dived into modern agricultural issues with a vengeance. However, their latest venture has all the balance and perspective of Nigel Farage faced with a chicken vindaloo and a team of migrant NHS workers.

Developed through the Wellcome Trust Experimental Stories Unit and written by Val McDermid, well-known for her crime novels, “Resistance” describes the impact of an outbreak of antibiotic-resistant swine erysipelas, which passes swiftly from contaminated sausages at a music festival to the general public exhibiting dreaded “purple spots” and collapsing at the supermarket checkout.

Alas, having listened to the first two episodes with more than a passing interest (after all, antibiotic resistance is a huge issue for our industry, both from an animal and human health perspective), it’s clear that an aluminium helmet and a “meat is murder” sign may be required listening accessories. The main protagonist is a slightly holier-than-thou vegetarian who was turned away from meat by the animal rights activists with whom she worked on a story and is currently scratching around to find freelance work after her editors became afraid of “real investigative journalism.”

Cue a cliched storyline, lined up in true pantomime fashion with neon signs alerting the listener to every plot development. The contaminated meat is traced back to a “factory” farm in an urban location, with pigs kept in “tiny pens with no room to lie down or turn around.” A specialist (non-local) vet throws antibiotics at the animals and a surly, secretive, Eastern-European-accented farm manager doesn’t seem keen on a journalist sniffing around.

The  racial stereotyping is unfortunate given how much UK agriculture relies on workers from Europe and beyond, and the farm portrayed as secretive, polluting water and soil, and utterly lacking transparency. By contrast, organic systems with “humanely-farmed” animals, and “well-scrubbed, rare breed pigs” are the dramatic ideal. Yet in real life, farm assurance schemes such as Red Tractor (which covers >80% of UK pork) ensure that pigs are kept in environments that provide sufficient space; are given suitable, healthy feed; and that waste is managed to prevent water or soil contamination. Does that mean that every pig farm is perfect? No. So does it mean that poor husbandry, environmental pollution and rampant overuse of pharmaceutical drugs is the norm? Absolutely not.

The casual listener might be horrified by the implications of antibiotic resistance for human health, but never fear, the drama suggests all will be well as long as your sausage comes from an organic Berkshire pig hand-raised on acorns. However, bacterial resistance to antibiotics occurs naturally and can be maintained or increased by any antibiotic use – in people, livestock or companion animals – not simply by use on conventional farms. Indeed, it’s vital to remember that organic operations are permitted to use antibiotics (as per the Soil Association organic standards), especially if they are the “best way to reduce suffering, save life or restore your animal’s health.” There is no blanket antibiotic prohibition on organic operations, as is often assumed.

Still more rhetoric invades the human health side of the drama – doctors try to dismiss and cover-up the public health implications, antibiotic researchers are hampered by lack of funds (possibly the most crucial but least discussed issue of the entire drama) and “big pharma” is lambasted for being more interested in developing drugs that generate long-term profit (e.g. diabetes or high blood pressure medication) than antibiotics that only need to be used once.

There is an immediate and definite need to develop new antibiotics both for animal and human health, yet if effective new drugs are found they’re unlikely to be distributed widely, but stored in case of an epidemic. Livestock farmers and vets have a huge responsibility in protecting both animal and human health, but so do doctors, food processors and ultimately all of us – simple hygiene measures, including effective hand-washing, are key to preventing the spread of disease.

Both national and global programs have been implemented to quantify, assess and reduce antimicrobial use; veterinary scientists are actively involved in on-farm research and interventions to reduce both antimicrobial use and resistance; and animal health companies (so-called”big pharma”) have joined with food processors, retailers, charitable foundations and human/veterinary medicine associations in taking a One Health approach (incorporating the health of people, animals and their environments) to making sure that antibiotics that are critically important for human medicine are withdrawn from animal use, and that the speed and spread of antibiotic resistance is reduced. Unless the rabid journalist has a serious epiphany in the third episode (to which I have not yet listened) it seems that facts are going to be overwhelmed by fiction as the efforts and advances made by global livestock producers are ignored.

I’m not suggesting that all drama should be absolutely true to life, but when real-life, topical, scientific issues are discussed, surely broadcasting agencies have a responsibility to be factual rather than alarmist? It’s unfortunate that this drama, written by a famous author and advised by a Professor of Microbiology at the University of Warwick, seems to have been developed without input from experts in veterinary science, animal production or on-farm antibiotic use. Furthermore, given the Wellcome Trust’s role as a global medical charity, one would assume that they have a responsibility to provide factual information, especially when their sponsorship must ultimately have been publicly funded. Instead, as with so many sensationalist dramas, it seems the world is going to end and we are the innocent victims of others greed for profit. Better switch to the organic sausage, or better still, the tofu surprise.

Does Size Matter? Dairy Efficiency Becoming Paramount During Crisis

Posted on by

Media articles relating to agriculture appear to fall into two groups. Those relating to small-scale agriculture are glowing accounts of farmers wearing overalls and straw hats; lovingly taking care of the land and animals according to holistic principles; and selling their produce at the local farmers’ market. By contrast, commentary upon large-scale agriculture invokes images of corporate-controlled factory farms with blatant disregard for animal welfare and local community issues; blithely pumping animal manure into water courses.

To consumers, the majority of whom do not understand agriculture, but have questions about how their food is produced, the choice (as presented by the media) is clear. Small farms must be better for the environment, the economy and the local community. According to the Food and Agriculture Organisation of the United Nations (FAO), we need to sustainably intensify food production over the coming years in order to feed the increasing global population. For many however, the concept of intensification and high-efficiency production systems appears to be contrary to the holistic, small-farm philosophy.

Small cows dominateI will be presenting at the “World Congress on Controversies and Consensus in Bovine Health, Industry & Economics” in Berlin later this week, and have been asked to debate the question “Are hyper-intensive, mega farms more efficient?” If we examine the science, the results are unequivocal.

To use the U.S. dairy industry as an example: over three-quarters (76.7%) of dairy farms have small herds (less than 100 cows) and only 4.2% are large, with more than 500 cows in the herd. Yet the contribution to total milk supply is disproportionate – those 76.7% of herds containing <100 cows produce only 13.7% of U.S. milk, whereas the 4.2% of farms with >500 cows produce 63.0% of U.S. milk. A 17% Large cows dominateincrease in milk yield per cow is exhibited in large herds compared to small herds – does this mean that so-called mega farms are more efficient? Yes. They have a higher output of milk per unit of input. Data from the FAO also shows that as milk yield increases, the carbon footprint (and other resource use impacts) per unit of dairy is reduced.

Yield per cow and herd size (metric)Does this mean that large herds are better? Not necessarily. There’s no measure of animal health, worker conditions, or community support in these data. Yet these issues are size-independent. It’s possible to have poor animal health or worker conditions on a small farm, just as it is on a large farm. I’ve seen some great small operations, but also visited amazing large farms, including a 1,200 cow dairy in SE England where I was extremely impressed to see that they had a hospital pen to segregate sick cows from the rest of the herd, and that it only contained 12 cows. A 1% morbidity rate. How would that compare to the average human workplace, school or city?

Size isn't importantIs there an ideal farm or herd size? A blueprint to lead the global dairy industry during the current crisis? No. Dairy farms vary considerably – it would be foolish to suggest that there is only one sustainable way to produce milk (although this approach is often taken by certain NGO groups). However, one thing is clear. As we approach a global population of 9.5+ billion people in 2015, we need to stop vilifying large farms and worshipping small farms, and instead promote efficient, well-managed, productive farms that can survive the crisis, regardless of size. As the saying goes – it’s not size that matters, it’s what you do with it that counts.

What Happens When We Don’t Like the Science?

Posted on by
Recently I’ve seen some criticism relating to Dr. Temple Grandin from a few people who are opposed to her ideas on animal welfare – namely that we need to listen to the consumer and understand what they think and want. It doesn’t seem like rocket science, does it? Ignore your consumers wishes and pretty soon you don’t have a market.

“Just show consumers the science, not the emotion…” seems to be the battlecry. “If somebody hasn’t published a peer-reviewed paper on it, they shouldn’t be allowed to say it!” Except it’s not as simple as that, is it? Just look at the furore over LFTB (lean finely-textured beef or so-called “pink slime”). A safe, technologically-sound, scientifically-approved product that, once it was labeled pink slime, was utterly undesirable to the consumer. Never mind that they were still happy to eat Twinkies, Slim-fast (just what is that pink powder?) or kelp juice (green slime?), the perception was out there that LFTB was gross, and no matter how much science was quoted, bang, out of beef products it went.

We can talk about science all we like, but sometimes that just isn’t going to get the message across. I can’t imagine that any consumer who goes into a battery chicken (caged layer) house or sees a photo of a pig in a gestation crate says “Wow, what a beautifully efficient and scientific system!” That response becomes even less likely when all they see is a photo of it on Facebook.

So what happens when the science doesn’t play nicely into our perceptions and beliefs? When about social science papers that show that consumers evaluate foods based on emotion, not science? Or survey data that shows that we can take consumers to a farm and explain agriculture…but that it doesn’t change the preconceived ideas that 75% of them already held?* Do we ignore the inconvenient science because we don’t like the answers? Keep banging the same drum and hope that we can maintain the status quo?

Here’s a thought. Rather than looking at agriculture through your own eyes, try and see it through the eyes of somebody else. Part of Dr. Grandin’s success can be attributed to that fact that, because of her autism, she can empathize with animals in handling systems. Isn’t time we followed her example and tried to think outside the cattle chute?

A Christmas Wish – May All Your Cows Be Like Your Best Cow

Posted on by

I love conversations that leave my brain firing on a million cylinders and open my mind to new ideas. I was lucky enough to have three such discussions this past week, one at an organic research farm; another at a 300-cow Jersey operation; and the most recent with three faculty at the University of Oxford with regards to the interactions between animal welfare and livestock sustainability.

Animal welfare is a touchy subject – many people appear to define excellent welfare as only including a narrow range of production systems or practices; and although everybody has their own image of what a “happy” animal looks like, it’s not always easy to identify or describe those systems without anthropomorphizing. Indeed, I’ve become increasingly aware that promoting improved productivity and efficiency as a means to improve sustainability can be misconstrued as encouraging the agricultural equivalent of a owning a Victorian dancing bear or cymbal-playing monkey – a “force the animals to perform, regardless of the cost in terms of animal welfare”-type philosophy (see picture below).

Troll

 

Yet such suggestions entirely miss the point, as any system that is consistently detrimental  to animal welfare is neither productive nor efficient on a long-term basis. We humans don’t perform well if we’re chronically underfed, stressed, sick, or housed in unfavorable environmental conditions – and neither do livestock.

Personally, my agricultural utopia would be one where all livestock operations, regardless of size, location or production system, exhibit both high productivity and excellent animal welfare. Admittedly, this leads to the difficult task of not only defining excellent welfare, but also the metrics and benchmarks by which it can be assessed within each operation. However, there is one overarching metric that can be measured, and improved on any farm or ranch – animal health. By definition, an animal that is chronically sick, lame or in pain cannot be said to be a example of good welfare.

As consumers, we want to know that the animals that provide us with milk, meat and eggs are healthy. Indeed, I imagine that even the most militant vegan opposed to the consumption of animal products would agree that animal health should be paramount. As producers, making sure that livestock are healthy is as ethically important as treating workers well. Plus, healthy animals are easier to manage: they grow faster; they have fewer incidents of  illness or death; and they produce more milk, meat or eggs. These improvements in efficiency and productivity also mean that we need less feed, less land, less water and have a lower carbon footprint per unit of food produced.

Let’s consider lameness in dairy cattle. A major animal welfare issue, it costs between $120 and $216 per incidence (UK costs below)* and is a major cause of cows being culled at or even before the end of their second lactation. Similarly, mastitis has a huge impact on both cow longevity and productivity, and costs the US dairy industry $1.7-2.0 billion per year. If just these two health issues were addressed, how many associated dairy cattle health and welfare issues would be improved; how much could dairy farm profitability be enhanced; and how much would the public image of dairy improve?

Every herd has its best cow – the one who is never lame, doesn’t suffer from mastitis, metritis or ketosis; and gets back in calf easily – all while having a high milk (and components) yield. There is no magic bullet to improve productivity and efficiency –  yet the discussions I’ve had in the past week conclusively demonstrated that that does mean suiting your system to your available resources and, though excellent health, nutrition, breeding and management, allowing every cow to perform like your best cow, every single day. I wish you a Merry Christmas and hope that in 2015, all your cows will be like your best cow.

*Lameness costs £180 pounds per incidence in the UK, or £15,000 per average herd annually. Mastitis costs the UK dairy industry £170 million per year.

Beta agonists have been a hotly debated topic in the media recently, after it was suggested that the use of Zilmax™ might be related to welfare issues in supplemented cattle (see note 1), and Tyson announced that they would not purchase cattle produced using the feed supplement.

As the global population increases and consumer interest in food production sustainability continues to grow, we know that to maintain the continuous improvements in beef sustainability that we’ve seen over the past half-century, we need to ensure that economic viability, environmental responsibility and social acceptability are all in place. All cattle producers obviously have the choice as to what tools and practices are used within their operation, but what are the big picture environmental and economic implications of removing technology use from beef production? Let’s look at two tools – beta agonists and implants (see note 2 below for an explanation of these tools).

Figure 1. Extra Cattle NeededIn a traditional beef production system using both tools, we’d need 85 million total cattle (see note 3) to maintain the U.S. annual production of 26 billion lbs of beef (see note 4). If we removed beta-agonists from U.S. beef production we’d need an extra 3.5 million total cattle to support beef production; losing access to implants would require an extra 9.9 million cattle; and removing both tools would increase total cattle numbers to 100 million (a 15 million head increase) to maintain the current beef supply (see note 5).

If we need more cattle to maintain beef supply, we use more resources and have a greater carbon footprint.

If we removed beta-agonists, we would need more natural resources to maintain U.S. beef production:

  • More water, equivalent to supplying 1.9 million U.S. households annually (195 billion gallons)
  • More land, equivalent to an area just bigger than Maryland (14.0 thousand sq-miles)
  • More fossil fuels, equivalent to heating 38 thousand U.S. households for a year (3,123 billion BTU)

If we removed implants, we would need more natural resources to maintain U.S. beef production:

  • More water, equivalent to supplying 4.5 million U.S. households annually (457 billion gallons)
  • More land, equivalent to the area of South Carolina (31.6 thousand sq-miles)
  • More fossil fuels, equivalent to heating 45 thousand U.S. households for a year (3,703 billion BTU)

If we removed both beta-agonists and implants, we would need more natural resources to maintain U.S. beef production:

  • More water, equivalent to supplying 7.3 million U.S. households annually (741 billion gallons)
  • More land, equivalent to the area of Louisiana (51.9 thousand sq-miles)
  • More fossil fuels, equivalent to heating 98 thousand U.S. households for a year (8,047 billion BTU)

Feed costs would increase by 4.0% without beta-agonists, 8.1% without implants and 11.0% without both tools. These costs ultimately would be passed on through every segment of the beef supply chain (including the retailer or food service segment) and ultimately onto the consumer, making beef a less-affordable protein choice.

In a world where one in seven children currently do not have enough food, keeping food affordable is key to improving their health and well-being. If we use productivity-enhancing tools in one single animal, the extra beef produced is sufficient to supply seven schoolchildren with their beef-containing school meals for an entire year. Is that a social sustainability advantage that we can afford to lose?

Although animal welfare is paramount for all beef production stakeholders from the cow-calf operator to the retailer, it is possible that the consumer perception of productivity-enhancing tools  may be harmed by negative comments on media articles relating to Zilmax™. There is no doubt that we will need to use technologies within food production in order to feed the growing global population, yet we need consumer acceptance of both the technologies that we use, and the reasons why we use them, in order to continue to secure market access for U.S. beef.

Consumer acceptance therefore needs to be a key component of our mission to continuously improve beef sustainability. That does not mean giving in to the uninformed whims of those who blithely assert that we could feed the world by returning to the production systems of the 1940’s or ’50s, but does offer an opportunity to reach out, listen to and engage in a dialogue with our friends, family, customers and colleagues about the advantages that technology offers. We have a bright future ahead, but only if we keep the torch alight.

Footnotes

1) Merck Animal Health have since pledged to conduct a thorough investigation into the issue and have temporarily suspended Zilmax™ sales in the U.S. and Canada.

2) Beta agonists are animal feed ingredients that help cattle maintain their natural muscle-building ability and add about 20-30 pounds of additional lean muscle instead of fat. Implants (sometimes called growth promotants or growth hormones), are placed into the ear and release hormones slowly, helping cattle maintain natural muscle-building ability while also decreasing the amount of fat gained. 

3) Includes beef cows, calves, bulls, replacement animals, stockers and feedlot cattle plus calves and cull cows from the dairy system.

4) Although this is a considerable amount of beef, it’s still not enough to fulfill current demand for beef in the USA and overseas.
