It’s #Februdairy!

Posted on by

Moo heard 2Two weeks ago, I sat in the audience for the Semex conference and heard two different presenters talking about the increasing market for plant-based foods and the myths, mistruths and misconceptions that abound about dairy farming. As a scientist, I know that we need five pieces of positive information to negate every piece of negative information. Lo and behold, #Februdairy was born!

Screen Shot 2018-01-31 at 13.41.25It’s a simple concept, a campaign to celebrate all things that are wonderful about dairy – from cows to cheese, young farmers to yogurt.

So let’s post as many positive dairy tweets (especially those with pics and videos) as we can during February. Facebook and Instagram posts work well too. Anything that you can do to keep the campaign going would be wonderful, even it’s just occasional retweets.

If you’d like to tag your posts using or you can, but please don’t feel you need to. There are some useful guidelines about engaging on social media here, here and here. Feel free to reach out to me too if you would like any more information @Bovidiva.

Unfortunately, there are some rather vile people out there too.  Please remember that we all need to support each other and that you can disengage from social media at any time. Don’t ever feel like you are alone in this (or in the industry as a whole) the Farming Community Network and the YANA Project are great resources if any of us need help or someone to talk to.

Together, lets show the world what a wonderful industry we have and celebrate dairy with #Februdairy!

Activists tell me that I deserved to get aggressive breast cancer at 25 – it’s karma.

I like to think that we live in a society where, as a whole, we are more tolerant than we were 50 or 100 years ago. Discriminating against people because of their race or gender is unacceptable, diversity is celebrated, and the idea of criticising somebody because of their religious beliefs is abhorrent to most of us.

Yet, over the past two weeks, I, and many of my friends and colleagues in the dairy industry, have been called rapists, murderers, liars and fakes. Total strangers have sent messages containing the most offensive swear words in the English language – and then been surprised when we don’t want to have a conversation about dairy farming with them. Just yesterday, somebody laughed about my breast cancer history – another said it was karma for eating meat and dairy products.

I would never wish cancer on anybody – the day that I was diagnosed was the worst of my life. I find it utterly abhorrent that some activists are using words like “rape” and “holocaust” to try and denigrate dairy and meat production. Trying to compare food production with these horrible crimes both dismisses and demeans the emotional and physical pain suffered by millions of people.

Screen Shot 2018-01-31 at 13.37.33We should not criticise anybody’s choice of food, diet or lifestyle – it’s wonderful that we all are free to make the choices that suit our beliefs and philosophies. If you don’t eat or enjoy dairy – that’s entirely your choice and it’s great that you have alternative foods that certainly weren’t around when I was a vegan 25 years ago!

Tomorrow marks the start of #Februdairy – 28 days of positive social media posts celebrating everything to do with dairy. I shall post more details tomorrow, but please, if you enjoy dairy foods, think about posting something to celebrate our dairy farmers, the cows (plus goats and sheep!) that provide us with dairy products, and that fact that we have so many delicious milks, cheeses, yogurts, butters and ice-creams to enjoy.

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.

Let’s Raise a Glass to the Dairy Cow

OLYMPUS DIGITAL CAMERAToday is Cow Appreciation Day and Elanco Animal Health have kindly asked me to write a few words for their 360º blog in praise of the magnificent foster mother of the human race. Here’s a short extract to whet your appetite:

“…My 3-year-old daughter often tells me: “Mummy, milk is important to help me grow” and, although we are incredibly lucky to live in a world with myriad food choices, it’s important to bear in mind that not all foods positioned near to dairy products in the supermarket have the same nutritional benefits.

In conversations with fellow parents, I have often heard the suggestion that young children should be transitioned away from dairy milk towards soy or other beverages, in the belief that any drink sold as “milk” is nutritionally-equivalent. The European Court of Justice recently ruled that plant-based beverages such as soy, almond or rice juice can no longer be labelled as “milk”, therefore this may reduce parental confusion, yet it seems that replacing dairy products with plant-based foods has already had significant effects…”

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!

Cattle, Cowgirl Boots And Cancer

581677_10153042743360587_388837289_nLast week I was lucky enough to chat with the fabulous Will Evans, a Welsh cattle and hen farmer on his Rock and Roll Farming podcast.

Unlike most of my media interviews, which are focus entirely on sustainability and have me spouting numbers like data is going out of fashion; this was a huge amount of fun and Will got me admitting to a celebrity crush, the fact that I have to put bacon and cheese on hot cross buns and the fact that, as an undergrad, I was so useless at presentations that even the lecturers felt sorry for me.

So if you fancy listening to a fabulous Welsh accent (Will) and a slightly overexcited Oxford/Shropshire/Montana-hybrid (me) discussing the best types of cheese, beating cancer at 25 and the perils of being a reformed vegan in addition to the best way to ensure future livestock sustainability (hint: there’s no one-size-fits-all), check it out here.

Jamie Oliver Should Be Presenting Friday Night Farming Facts – Not Feasting On Foodie Fiction

Posted on by

Commercial dairy cows in Cumbria – should they be “retired” before slaughter?

Good grief. Just when I think I’ve heard it all, another food pundit comes up with an idea so daft that you could bottle it and sell it as vegan, gluten-free, dairy-free, humanely-reared organic water. The latest brainwave from Jamie Oliver is to “retire” old dairy cows onto pasture, where they can graze for four years before producing highly-marbled beef. Contrary to most of the breed-related marketing, Holstein beef is pretty good, so it’s a mouth-watering concept until we take a step back and think about the actual sustainability impacts.

Producing beef from cull dairy cattle? Excellent idea. I once had a heated argument with an activist protestor outside the Smithsonian Museum in Washington DC who seemed surprised that, when he told me that most cull dairy cows end up as burgers, I didn’t renounce my heathen ways and immediately seek out the nearest tofu burrito. It makes perfect sense – where would be the logic in discarding an entire cow’s worth (~301 kg) of nutritious, delicious beef simply to bury, burn or use the meat for non-food purposes? Indeed, ~50% of the UK (and ~24% of the US) beef supply comes either from cull dairy cows or dairy calves reared for beef.

Is there an argument for giving extra feed to cows that are going to be culled so that they get a little fatter and produce tastier beef? Yes indeed, adding value to cull dairy cows is a great idea, especially when the beef price is high. But here’s the rub. The average dairy cow in the U.K. is culled at 6.4 years of age. By that time she should have reached her mature weight, which means that the majority of extra weight she puts on in “retirement” is fat. Although we love the streaks of intramuscular fat that we see in a steak (marbling) and enjoy the depth of flavour that gives to the meat, the vast majority of fat on a carcass isn’t particularly edible. So we’re feeding a cow for four years of retirement in order to discard (or rather render into tallow – perhaps to make some £5 notes?) a significant proportion of the weight that she gains.

A cow will eat 2-2.5% of her body weight in dry matter every single day. Four years of feeding a 700 kg cow = 4 x 365 days x 700 kg x 0.025 = 25,550 kg of feed dry matter, or 106,458 kg of fresh grass given that it’s only ~24% dry matter. Plus 4-years worth of drinking water, manure and greenhouse gas (GHG) emissions. A hefty environmental impact compared, for example, to rearing two beef steers on the same amount of pasture over a 4-year period, in addition to culling the dairy cow when she leaves the herd (sans retirement). That scenario would provide 200% more beef (~900 kg total, even allowing for the lighter weight for grass-finished vs. grain-fed steers) from the same amount of pasture and with a smaller total quantity of manure and GHG emissions because the growing animals are lighter in weight throughout, therefore excrete and emit less*.

I can’t decide whether the increasingly asinine proposals for sustainable food production propounded by Jamie Oliver’s “Friday Night Feast” programme, which recently left the casual viewer with the impression that welfare of housed dairy cows is equivalent to that of battery hens are serious, or simply a way to court fame through controversy. However, the number of tweets lauding the programme’s food philosophy is alarming given the amount of time devoted to non-sustainable ideology. Time for TV programmers to redress the balance with some Friday Night Facts vs. Fiction?

*Note that I have not accounted for the beef cows needed to produce the steers, nor for the cost of rearing the dairy cow or the heifer needed to replace her in dairy herd. This is not a full system assessment, but simply about the best use of a unit of pasture area – adding fat to a mature cow (less efficient) or adding muscle and fat to growing animals (more efficient)

Having Your Beef and Spending It? Don’t Let Moral Indignation Overcome Common Sense.

Posted on by

My Twitter feed has lit up like a firework this week with the news that cows are being murdered to produce the new plastic British £5 notes. Or, to correct the sensationalism with science, the notes contain a trace of tallow in the polymer that’s used to make them. Tallow is a by-product of beef production – it’s effectively the fat on the animal that we don’t want to eat, and has been used for centuries in a myriad of products.

Let’s be very clear here. No cows are being slaughtered (murdered!) to make £5 notes. Cattle are either slaughtered for meat or euthanised due to illness – there are no Bank of England-sanctioned posses stringing up helpless cattle as a license to print money (literally). Fortunately, we are able to use the portion of the animal’s carcass that we can’t (or won’t) eat to manufacture products that would otherwise rely on synthetic chemicals.

Not surprisingly, the majority of the outcry has come from vegetarians and vegans. While I will defend the right of anybody to choose what they eat or wear (note that I am not criticising or denouncing anybody’s religious beliefs here), the current protests seem to be slanted towards choosing to be offended by a minor point, rather than any semblance of logic.

According to a rather nifty (yet accurate) calculation by the guys at Vice, it would take 23 kg of tallow to make all the new £5 notes that will be in circulation by the time the old ones are phased out. The total tallow yield per animal is ~40 kg, so it would take just over half of one animal (23/40 = 0.58) to produce all the tallow for the UK’s total £5 note requirements.

5-noteMany of those who are protesting are vegetarian (as opposed to vegan), thus still consume milk, eggs, honey and other non-meat animal products. Given that 20% or more of the cattle slaughtered in the UK are adult cows and bulls (i.e. they have reached the end of their productive life in the dairy or beef herd rather than being specifically reared for meat), it makes sense to utilise whatever components of their carcasses are suitable for industrial purposes rather than diverting them into landfill or incinerators. If dairy consumption is acceptable to vegetarians, can it really be claimed that bank notes containing a fraction of the spent dairy cow’s carcass as tallow are not?

by-products-from-animal-agAs I have mentioned in previous blog posts, myriad everyday products contain by-products from cattle. Given the current outcry, once can only assume that those who shun the new £5 notes also refuse to travel in cars, buses or on bicycles (as (t(as tyres contain stearic acid, again from tallow); do not drink from bone china mugs; or disavow beer filtered through isinglass. Or, as with so many other issues, is it an opportunity for a small minority to protest and promote their personal dietary choices behind the guise of population-wide offence?

The online petition against the new £5 notes currently has >129,000 signatures. Obviously we all have the right to protest against issues that alarm, anger or offend us, and social media gives those opinions far greater weight than we had in the past. Yet is this really an issue that is more important (as judged by media coverage) than 11-year-old girls being forced into marriage? Or livestock being slaughtered without first being stunned? Or asylum seekers being refused entry? Perhaps in this case, the moral minority need to examine the bigger picture, and consider the issues that really matter.

 

 

 

Cows, Cows, Everywhere, and Not a Steak to Eat. What Happens if We All Become Vegan?

Hereford calf – innocent victim of our murderous lust for meat?

I have previously blogged about the potential impact of us all becoming vegan with reference to the U.S. beef and dairy industries, but given the recent haranguing of several Twitter friends (and myself) by some very passionate vegans, I thought it was worth updating the post for the UK livestock industry.

Let me make it very clear – I am totally happy for anybody to choose whichever diet they prefer: omnivore, vegetarian, vegan, flexitarian etc. No problem. I have to admit I find it interesting when people claim that they are vegetarian but that they occasionally eat meat (5% of Australians consider themselves as vegetarian but only 2% eat a meat-free diet!), but it’s great that we are able to choose from a wide variety of diets and foods. However, I get really irritated when people suggest (or insist) that I shouldn’t eat meat or fish because they believe that it’s morally wrong. Food has almost become a modern faith issue – the same intensity and fervour of 19th century missionaries trying to convert “heathens” is applied by the more activist vegetarians and vegans.

Meat-free Australia

Interestingly, every single vegan I have conversed with on Twitter appears to believe that cattle only reproduce because they are forced to by the farmer. Accusations such as the one in the tweet below are common – because artificial insemination is regularly used within the dairy industry (although a significant proportion of dairy farmers also use bulls for natural service), cows are seen to be “forced” to breed, or even “raped”.

Angry vegan

So, if we as a vegan population did not eat milk, meat or eggs and did not “enslave” or control cattle, but instead turned them out to live a natural life, would they cease to breed? It’s a nice idea, but, it’s false. If a bull has access to cows in heat, he’s going to pursue that cow, even if it means breaking into the next field. Cattle don’t breed like rabbits, but bulls are rather akin to hormonal teenagers when responsive cows are in close proximity.

Anti-animal agriculture activists often purport that a cow can live for 20+ years in her “natural” state compared to a farmed animal – so being a data nerd, I did the maths. Let’s assume that we turn all the dairy cows out tomorrow, and the following assumptions hold true: 1) cows first calve at two years of age and that 75% of cows have a calf every year*; 2) 85% of those calves survive (calf mortality would increase because we would not care for (exploit?) new-born calves); and 3) each cow or bull lives for 20 years. Admittedly that doesn’t account for the cattle that would be hit by cars, or die from starvation through lack of available grazing in 5, 10 or 20 years time, but being good vegans, we’d feed them, right?

If we all became vegan - UK

We currently have ~4.2 million dairy cattle (1.9 million dairy cows, plus calves, heifers and bulls) in the UK. Within five years we’d have 19.2 million cattle in the UK, within 20 years we’d have 285 million – a 68.6-fold increase on our current national herd. That’s 68.6x more cattle belching methane, drinking water and producing waste, every single day, all as a result of our changing our diet in a misguided attempt to reduce environmental impact.

It’s a nice, simplistic, oft-suggested argument that we shouldn’t eat meat or dairy products in order to save the planet, yet the conflict between veganism, animal welfare, and environmental impact is clear. Climate change will be solved by us turning vegan? Not unless we reconcile ourselves to killing animals without eating them.

*75% would be a low calving % on a beef or dairy farm, but let’s assume that natural service in the wild is less efficient 

If We Can Replace Antibiotics with Homeopathy, then Cheese is the New Miracle Cure!

Posted on by
IMG_1903 cropIn the Guardian this week, HRH Prince Charles proposed homeopathy as a solution to antibiotic resistance, citing his “agro-ecological” farm as an example of one that has cut antibiotic use by using homeopathic treatments.

Given the concern over bacterial resistance to medically-important antibiotics, it is vital that we find alternatives. Yet they also must have a biologically sound mode of action and be proven to be effective. It is difficult to conceive how a solution so dilute that not one molecule of active ingredient remains, where the premise of the mode of action depends on water having a “memory” of the ingredient (as opposed to all the other contaminants within that water), can possibly have any verifiable impact on disease. Indeed, there are no studies to date that show positive, replicable effects of homeopathy compared to conventional treatment.

Personally, I have no issue with any alternative therapy has been shown to be an effective alternative to conventional drugs (note that homeopathy does not fall into this category). When I underwent chemotherapy for breast cancer, I had some reiki sessions. Did I believe that energy was being channeled by the reiki healer and making me better? Honestly, no. Would I have ever considered giving up the chemotherapy? Absolutely not. But the focused breathing and relaxation certainly helped with pre-chemo anxiety. Would taking Rescue Remedy or a similar homeopathic preparation have helped? If I’d believed that it would – yes, probably. But that is biased by the placebo effect – it’s not the same as the treatment being independently effective. One of the claims made for using homeopathic treatments in animals is that they are independent of the placebo effect – they don’t have the expectation that the tincture administered is going to cure their lameness or mastitis. Yet when we assess the results, it’s not the animal who’s reporting the success or failure of the homeopathic treatment, it’s the farmer.

So let’s examine a scenario. A farmer has two mildly sick cows (e.g. slightly lame, or unwilling to eat with a raised temperature) within the herd. Both are moved to the hospital pen, given fresh bedding, water and feed plus a homeopathic remedy. Cow A gets better – hoorah for homeopathy!  Cow B doesn’t and has to be treated with antibiotics – boo! Does this mean homeopathy works in 50% of cases? No. There’s no control treatment here, no evidence that Cow A wouldn’t have got better without homeopathy – some diseases just need time, TLC and the cow’s own immune system for recovery. Did the farmer cut antibiotic use? Yes – Cow A didn’t receive it. Yet again there is no evidence that this is due to the homeopathic treatment. How many times have we as humans debated whether to go to the doctor because of a minor ailment, then have found that it’s cleared up without medical treatment? It’s not miraculous, it’s simply our immune systems functioning as they are intended to.

In the absence of controlled experiments that compare homeopathic treatments to both conventional antibiotics and no veterinary treatment (save for good animal husbandry), it is disingenuous to claim that homeopathy is successful in treating bacterial disease or can effectively be used to replace antibiotics. We need to look to veterinarians and scientists when making decisions about animal care and treatment rather than relying on anecdotal data from those with royal connections. After all, HRH Prince Charles may have reduced antibiotic use on his farm, but I can also claim to have reduced antibiotic use in my household through dairy consumption – my toddler has a serious cheese addiction and has never had to take antibiotics. Hoorah – cheese is the new homeopathy!!*

(*obviously I am being sarcastic here for those who missed it, though the extent of cheese consumption and fact that she’s never had antibiotics are both entirely true)
