“Cows Have to be Milked”

I have come across this argument before, but not in several years. Today, two fellow students reminded me of this common argument: “Cows have to be milked.”

Searching the Internet, I came across conflicting information. Some sources claim that the cows may contract Mastitis, an inflammation of the mammary gland. I also came across several sources that state cows become agitated when not milked. Others still, claim that the teats will eventually just dry up. I have contacted the Holstein Association for more information. (Holsteins are the dominant breed of dairy cow in the United States.)

[Update 05/23/12] At the time I originally published this article, I did not have a response from the Holstein Association. Now I do:

“Hi Pierce,

While we are not a veterinary organization, which would be the best source, I have lived on a dairy farm my entire life and can hopefully help clarify it for you.

In general, if a milking animal is not milked for an extended period of time (more than 1 or 2 days for a cow giving a normal volume of milk – dairy cows are typically milked two or three times per day), they are likely to become ill and may develop mastitis, which is an inflammation and infection in the udder. There is no reason however that a normally functioning dairy farm would not milk their cattle on a regular schedule. At the end of their lactation (which typically lasts 305 days), when cows are giving a minimal amount of milk, dairymen cease milking them for their “dry period.” This is different from just not milking the cow, which may cause to be sick, because a cow is naturally giving less and less milk, and is “dried off” as sort of a vacation before she has her next calf and begins milking again. Dry periods typically last about 60 days.

If you have further questions, feel free to contact me.

Thank you!

Firstly, I would like to thank Lindsey Worden for being kind enough to respond to my query. I am going to defer to her and her organization’s experience in caring for cows. So yes, if the cows are not milked, it is detrimental for them.

Physical ramifications aside however, this argument is problematic for several reasons. In essence, this argument is saying that if the cows are not milked, they will suffer detrimental effects. Animal use however, is inherently detrimental. Dairy cows in particular, typically only live five to six years before being slaughtered.

It is important to remember that dairy cows, like all nonhuman animals, are economic commodities. Outside of this system, the cows can live 12 to 15 years, but in the dairy industry, they are only economically viable for a fraction of that time. So if one is concerned with the welfare of dairy cows, then how can one support a system that systematically kills them when they are no longer profitable?

Furthermore, if dairy cows suffer detrimental effects from not being milked, it is equally important to remember that this is a problem we created on several levels.

Without our interference, the milk would normally be consumed by their calf. In the dairy industry however, this only happens for a few hours before the calf is separated from the mother. We are concerned with the welfare of the cow and so we justify milking them. At the same time, we fail to recognize that we created the original problem that requires their constant milking.

We not only created the problem, we created the cow. Between around 1925 and the present, cows have been selectively bred to produce four times as much milk, which now averages around 16,000 pounds a year per cow. If not being milked is painful, it is because we bred them to secrete more milk than they ever would have naturally. Through artificial insemination and other techniques, we currently keep around nine million cows a year. We created beings that by our design require our use. If we truly care about the welfare of the cow, the best way to alleviate their pain is not to milk them, but rather to not continue breeding them.

Furthermore, looking solely at the dairy producing cow fails to recognize the interconnectedness of the animal agriculture system. If one is buying milk with the belief that they need to be milked and this contributes to the cow’s welfare, one must also recognize that they are condemning a male calf to a beef, or more likely, veal farm. As previously stated, all animals in this system are economic commodities. When that cow stops producing milk, it is slaughtered. When the father of the calf stops producing sperm, it is slaughtered.  Their offspring will either end up in the beef, dairy, or veal farm. They all end up in the slaughterhouse. Buying milk creates these other lives, and the cycle never ends.

  1. I know this is an old post but I sincerely appreciate your information. This is the most honest post on this topic I have found. My boyfriend’s parents argue this issue with me constantly as his father was raised on a farm, though wasn’t truly a part of the activities. I eventually gave up my argument and asked his mother if she continues to produce milk after her children and requires constant milking for her health. Oops. Got a little frustrated and rude but I think it made her think about all mammals and what milk production is like since she did breastfeed her sons and did eventually dry up. She did mention she never really thought about that fact and thought dairy cows were “special” in this aspect. Again…thank you for providing truth in your argument and contacting an organization that knows more about dairy cows than average people.

  2. However, they have said that they can stop milking them for a while when they stop producing. I think it would be possible to stop for good at that point

    • They could, and at that point the cow would no longer be profitable and would be slaughtered. That’s what it means to be an economic commodity.

  3. Thank you for this article. When I had my baby I breast fed him; when he stopped breastfeeding, my milk went away; a naturally painful experience, but it was over in a few days. It was nothing compared to labor!! The same would happen for any animal who milk feeds their babies.

    We need to stop breeding these poor creatures for our food; it is inhumane and utterly disgusting. (I didn’t mean that pun) I wish we would see the unjust nature of this practice and find a better, more sustainable method of feeding ourselves.

  4. […] According to the Holstein Association, this is true: “In general, if a milking animal is not milked for an extended period of time (more than one or two days for a cow giving a normal volume of milk – dairy cows are typically milked two or three times per day), they are likely to become ill and may develop mastitis, which is an inflammation and infection in the udder.” […]
