Given the chance, cows nurture their young and form lifelong friendships with one another. They play games and have a wide range of emotions and personality traits. But most cows raised for the dairy industry are intensively confined, leaving them unable to fulfill their most basic desires, such as nursing their calves, even for a single day. They are treated like milk-producing machines and are genetically manipulated and may be pumped full of antibiotics and hormones in order to produce more milk. While cows suffer on factory farms, humans who drink their milk increase their chances of developing heart disease, diabetes, cancer, and many other ailments. Cows Suffer on many intensive Dairy Farms
Cows produce milk for the same reason that humans do—to nourish their young—but calves on dairy farms are taken away from their mothers when they are just 1 day old. They are fed milk replacers (including cattle blood) so that their mothers’ milk can be sold to humans.
Female cows are artificially inseminated shortly after their first birthdays. After giving birth, they lactate for 10 months and are then inseminated again, continuing the cycle. Some spend their entire lives standing on concrete floors; others are confined to massive, crowded lots, where they are forced to live amid their own feces. A North Carolina dairy closed its doors following revelations from a whistleblower that the cows were forced to eat, walk and sleep in knee-deep waste.
Cows have a natural lifespan of about 20 years and can produce milk for eight or nine years. However, the stress caused by the conditions on factory farms leads to disease, lameness, and reproductive problems that render cows worthless to the dairy industry by the time that they’re 4 or 5 years old, at which time they are sent to be slaughtered.
On any given day, there are more than 9 million cows on U.S. dairy farms—about 12 million fewer than there were in 1950. Yet milk production has continued to increase, from 116 billion pounds of milk per year in 1950 to 206 billion pounds in 2014.8,9 Normally, these animals would produce only enough milk to meet the needs of their calves, but genetic manipulation—and, in some cases, antibiotics and hormones—is used to cause each cow to produce more than 20,000 pounds of milk each year. Cows are also fed unnatural, high-protein diets—which include dead chickens, pigs, and other animals—because their natural diet of grass would not provide the nutrients that they need to produce such massive amounts of milk.
Painful inflammation of the mammary glands, or mastitis, is common among cows raised for their milk, and it is one of dairy farms’ most frequently cited reasons for sending cows to slaughter. There are about 150 bacteria that can cause the disease, one of which is E. coli. Symptoms are not always visible, so milk’s somatic cell count (SCC) is checked to determine whether the milk is infected. Somatic cells include white blood cells and skin cells that are normally shed from the lining of the udder. As in humans, white blood cells—also known as “pus”—are produced as a means of combating infection. The SCC of healthy milk is below 100,000 cells per millilitre; however, the dairy industry is allowed to combine milk from all the cows in a herd in order to arrive at a “bulk tank” somatic cell count (BTSCC). Milk with a maximum BTSCC of 750,000 cells per millilitre can be sold. A BTSCC of 700,000 or more generally indicates that two-thirds of the cows in the herd are suffering from udder infections.
Studies have shown that providing cows with cleaner housing, more space, and better diets, bedding, and care lowers their milk’s SCC as well as their incidence of mastitis. A Danish study of cows subjected to automated milking systems found “acutely elevated cell counts during the first year compared with the previous year with conventional milking. The increase came suddenly and was synchronized with the onset of automatic milking.” Instead of improving conditions in factory farms or easing cows’ production burden, the dairy industry is exploring the use of cattle who have been genetically manipulated to be resistant to mastitis.
The Veal Connection
If you drink cow’s milk, you’re subsidizing the veal industry. While female calves are slaughtered or kept alive to produce milk, male calves are often taken away from their mothers when they are as young as 1 day old to be chained in tiny stalls for three to 18 weeks and raised for veal. Calves raised for veal are fed a milk substitute that is designed to make them gain at least 2 pounds per day, and their diet is purposely low in iron so that their flesh stays pale as a result of anemia. In addition to suffering from diarrhoea, pneumonia, and lameness, calves raised for veal are terrified and desperate for their mothers.
Large dairy farms have an enormously detrimental effect on the environment. In California, America’s top milk-producing state, manure from dairy farms has poisoned hundreds of square miles of groundwater, rivers, and streams. Each of the more than 1 million cows on the state’s dairy farms excrete 18 gallons of manure daily. Overall, factory-farmed animals, including those on dairy farms, produce 1.65 billion tons of manure each year, much of which ends up in waterways and drinking water. The Environmental Protection Agency reports that agricultural runoff is the primary cause of polluted lakes, streams, and rivers. The dairy industry is the primary source of smog-forming pollutants in California; a single cow emits more of these harmful gasses than a car does.
Bodies Fight Cow’s Milk
Besides humans (and companion animals who are fed by humans), no species drinks milk beyond infancy or drinks the milk of another species. Cow’s milk is suited to the nutritional needs of calves, who have four stomachs and gain hundreds of pounds in a matter of months, sometimes weighing more than 1,000 pounds before they are 2 years old.
Cow’s milk is the number one cause of food allergies among infants and children, according to the American Gastroenterological Association. Most people begin to produce less lactase, the enzyme that helps with the digestion of milk, when they are as young as 2 years old. This reduction can lead to lactose intolerance. Millions of Americans are lactose intolerant, and an estimated 90 % of Asian-Americans and 75% of Native and African-Americans suffer from the condition, which can cause bloating, gas, cramps, vomiting, headaches, rashes, and asthma. A U.K. study showed that people who suffered from irregular heartbeats, asthma, headaches, fatigue, and digestive problems “showed marked and often complete improvements in their health after cutting milk from their diets.”
Calcium and Protein Myths
Although American women consume tremendous amounts of calcium, their rates of osteoporosis are among the highest in the world. Conversely, Chinese people consume half as much calcium (most of it from plant sources) and have a very low incidence of the bone disease.33 Medical studies indicate that rather than preventing the disease, milk may actually increase women’s risk of getting osteoporosis. A Harvard Nurses’ Study of more than 77,000 women ages 34 to 59 found that those who consumed two or more glasses of milk per day had higher risks of broken hips and arms than those who drank one glass or less per day. T. Colin Campbell, professor of nutritional biochemistry at Cornell University, said, “The association between the intake of animal protein and fracture rates appears to be as strong as that between cigarette smoking and lung cancer.”
Below is a slideshow of the extent of cruelty that is apparent in many countries. Not all farms are as obviously cruel as some of the pictures here – but the truth still remains that cow’s milk was meant for calves and not for us.
