The suffering of farmed cattle

Dairy cows

The size of the total cattle herd in the UK – including both dairy and beef animals – is around 10 million. Of these, 1.8 million are adult dairy cows.

In order to produce commercial quantities of milk, dairy cows are forced to endure a constant cycle of pregnancy and birth. Lactation does not occur unless this cycle is perpetuated. Calves are usually removed from their mothers within 24 hours of birth, after suckling their mother's first antibody-rich milk, known as colostrum. Separation of mother and infant causes acute anxiety and suffering for both animals. Mother cows have been known to break out of fields and then walk for miles to be reunited with calves taken to auction.

The calves' fate is one of the industry's dirty secrets. Each year, over half a million unwanted calves are born in the UK. Many females replace their worn-out mothers in the dairy herd. But the males are often regarded as waste by-products. Some are reared on veal farms for a few months before being slaughtered; others are killed within a week or two for baby food, or for cheese and pie ingredients. Some are simply shot in the head shortly after birth. Every year in the UK tens of thousands of calves are slaughtered so that farmers can sell their mothers’ milk.

Milk-producing machines

Dairy cows in the UK are typically black and white Holstein/Friesians, selectively bred to provide maximum milk yields. In an unfettered state, a cow will feed her calf for approximately six to eight months. Milk is secreted at a maximum rate of about eight to ten litres per day, which the calf suckles on four to six occasions. The mother produces less than 1,000 litres throughout the duration of her lactation, storing approximately two litres in her udders at any one time.

In modern dairy farming, however, cows can be expected to produce between 6,000 and 12,000 litres during their ten-month lactation. This means they may be carrying as much as 20 litres each at any one time. Producing so much milk puts the cows’ bodies under enormous strain.

Exploitation of the reproductive system

The most common technique used to impregnate dairy cows is artificial insemination. But, increasingly, powerful hormones are being used to force high quality cows to produce large numbers of embryos, which are surgically removed and inserted into lower grade females who then bring the calves to term.

Housing

Dairy cows are usually kept outside on pasture from mid-spring to mid-autumn, but for six months of the year they are kept indoors. Housing typically consists of concrete cubicles around a central communal area. The cubicles are separated by metal bars and must have suitable bedding material on the floor, which can include straw, wood shavings or ash. Urine and excrement is collected in a passageway behind the cubicles, or passes through slats in the floor of the communal area. Where slated floors are not used, passageways should be cleared twice a day to prevent slurry from building up.

Cow in cubicle

Such housing is usually barren, with little to stimulate the cows, and has been associated with behaviour problems such as aggression and bullying. Housing cows in close proximity for long periods also has implications for their health, including an increased risk of mastitis, lameness and contagious diseases.

Around ten per cent of dairy cows in the UK are now being housed all year round in what have become known as ‘zero-grazing’ units. Such operations only compound the issues already associated with housing cows for long periods and prevent them from expressing many of their natural behaviours.


Lameness

Between 20-40 per cent of British dairy cows are lame at any one time. In fact, inspections of the feet of cull cows at slaughter reveal evidence of past or present foot damage in nearly all animals. Lameness is caused by a number of factors. These include the quantity of bedding available, the move towards cubicle housing and the now near universal practice of feeding animals wet, fermented grass (known as silage), rather than dry hay. Silage produces wet faeces and acidic slurry, which can soften the feet and cause infections.

Also implicated in lameness is the reliance on concentrated feed supplements, which are difficult for these slow-digesting ruminants to cope with. The result is the release of inflammatory substances into the bloodstream, which lead to a condition known as laminitis, an acutely painful foot disorder. Another important reason for dairy cow lameness is the vast size and weight of the modern animal's udder. It is so large and distended that most cows simply cannot stand or walk properly.

Mastitis

Dairy cows are prone to infection of the udder caused by bacteria and other environmental pathogens entering via the teat canal. This acutely painful condition is known as mastitis and can often cause pus to seep into milk. There are around 50 cases of mastitis for every 100 cows during a year and current regulations allow milk to contain hundreds of millions of pus cells per litre before being considered unfit to drink.

Other illnesses

About 7-8 per cent of cows suffer from the condition known as ‘milk fever’ in the course of a year. This is caused by the sudden depletion of calcium reserves each year from the heavy burden of birth and lactation. This can cause muscle tremors and weakness, bloating, constipation and even coma and death if not quickly treated.

Slaughtered dairy cow

Some cows also get ‘grass staggers’ caused by a lack of magnesium in the diet. General depletion of nutrients caused by increasing intensification also triggers cases of brucellosis and viral infections, as well as susceptibility to salmonella bacteria.

Cows naturally live for as long as 25 years, but by the time they reach four or five on modern dairy farms, they are likely to be physically exhausted, lame and infertile. No longer able to produce the amount of milk demanded of them by the dairy industry, these worn-out animals are sent to a slaughterhouse.

Beef cattle

There are around 1.6 million adult beef cows in the UK. As well as suckling their own calves, around 70% of youngsters born to dairy animals are also raised within beef herds. From the beef farmer's point of view, the heavier and "beefier" his calves the better. Specialist companies dealing in bull semen for artificial insemination (AI) provide the means to achieve this.

The most popular breed chosen to provide semen is the Belgian Blue. This animal carries a recessive gene for "double muscling", so-called because of the enormous muscles, particularly on the hindquarters. Belgian Blue stud bulls have to be born via Caesarean section because their sheer size makes natural delivery impossible.

Mutilations performed on cattle

Male calves reared for beef are often castrated, despite being slaughtered before they reach sexual maturity. Methods commonly used include surgical castration, tight rubber rings that restrict blood flow, and appliances that crush the spermatic cord of each testis - the so-called "bloodless castrator".

Both dairy cows and beef cattle are de-horned - a painful procedure - to prevent animals injuring each other. Horns contain both blood circulation and nerve endings, and so local anaesthesia and cauterisation are necessary to stem bleeding. If horns have already developed, they are removed with saws, horn shears or cutting wire.

Young animals whose horns are not established can be disbudded. A hot iron is applied to the horn-forming tissue when the calf is 4-6 weeks old, permanently preventing growth.

Disease

The BSE crisis was followed in the winter of 1996/97 by a serious outbreak of food poisoning created by meat infected with E. coli 0157 bacteria. Twenty people died in a series of outbreaks in Scotland.

BSE cows

More than 700 types of E.coli have been identified. They are mainly harmless and inhabit the intestinal tract of people and other warm-blooded animals but a few strains, including the notorious O157:H7, can be deadly.

O157:H7 is found in the guts of many animals, but mainly cows. The increased number of human cases has been attributed to the intensification of farming practices and the consequent widespread use of antibiotics. Studies in France, Sweden and Canada have identified a positive correlation between the cattle density of an area and rates of human infection.

Consuming contaminated beef products is the most common source of infection, but the disease can be spread by any food or drink that has been tainted by animal manure.

Slaughterhouses are an obvious place for contamination of meat. Operators are urged to ensure the animals’ skins are not covered in faeces, and prevent the spillage of the digestive tract contents during and after organ removal. However, in 2008, secret filming by BBC journalists found carcasses at a number of Welsh abattoirs which had been health-marked by inspectors yet were contaminated by faeces.

Live Transport

Current EU rules allow cattle to travel for 14 hours without a rest or water. They must have a rest period of at least one hour after a 14 hour journey, after which, they may be transported for a further 14 hours. If the destination can be reached within another 2 hours then they may go a full 16 hours. After the second 14 hour journey, if the destination has not been reached the cattle must be unloaded, given food and water and rested for 24 hours. The journey times can then be repeated and this pattern can be repeated infinitely.

A number of organisations and politicians have created an online petition campaign to limit the maximum overall journey length to 8 hours. Whilst this would be a considerable improvement on current legislation, it is still a long time to be spent in a confined space with no room to turn around, lie down and without access to water.

Go Meat and Dairy-Free

Killing an animal for food can never be regarded as humane. Animals’ lives are as important to them as ours are to us and none go to the knife willingly. Choosing organic or free-range over factory farmed meat, milk or eggs, continues to cause pain and suffering. The only viable solution to end animal suffering is to adopt an animal-free diet.
