How is pig milk produced?

Do pigs make milk?

Yes. Like all mammals, a sow (female pig) produces milk after giving birth. It is made to feed her piglets, usually for several weeks. Pigs are farmed for meat, not for dairy.

How is pig milk produced and released?

Milk is made in the mammary glands and comes out of 8 to 16 teats, each giving only a small amount. A sow does not let milk down on demand like a dairy cow. The piglets stimulate her, and milk flows for only a short time, usually less than a minute, about every hour or so. Some researchers argue this is a main reason pigs were never used for milk.

Can you milk a pig?

It has been done in tiny amounts, with several people and special effort, and some sows are aggressive when nursing. Using a machine or a hormone to trigger let-down is possible in research but is not practical on a farm. It is not a normal farm process.

What does pig milk contain?

A study of sows (Craig et al., 2019) measured fat pooled across colostrum and milk samples from the first 21 days of about 5.7 to 6.3 percent, protein about 5.1 to 5.7 percent and lactose about 5.3 to 5.5 percent. In the first days, colostrum is rich in antibodies for the piglets. Compared with cow milk, other sources say it is higher in fat and solids and tastes stronger.

Do people drink pig milk? How does it taste?

It is not drunk as a normal food anywhere that we could verify. Those who tried it describe it as rich, somewhat gamey and watery. We found no safety rules for it, so we do not recommend it, especially unpasteurized.

Can pig milk make ice cream or cheese?

Cheese has been made in small experiments. There is no commercial pig-milk ice cream that we could confirm. See the related question about cheese and butter.
