Pig milk

Pig milk is milk from pigs, and is typically consumed by piglets. It is similar in composition to cow's milk, though higher in fat and more watery. Pig milk is seldom obtained for human uses and is not considered to be a viable agricultural product. Several attempts have been made to produce pig milk cheese, some of which have been successful.

Pig milk contains 8.5% fat compared to 3.5% in cow's milk. It has similar colostrum composition in terms of protein, fat, and lactose, when compared to cow's milk. Pigs with high-protein diets produce more milk compared to those on low-protein diets. It is also described as more gamy than goat's milk and seems more watery than cow's milk.

There are a number of reasons why pig milk is not considered suitable for human consumption or commercial production. Pigs are considered difficult to milk. The sow herself is reluctant to be milked, may be uncooperative or become spooked by human presence, and lactating pigs may be quite aggressive. There are 8 to 16 small nipples, each giving little milk for a short duration. A cow's milking time can be around ten minutes compared to fifteen seconds for a pig. A sow may produce only 13 pounds of milk per day compared to a cow's production of 65 pounds. (Production has been estimated using a system of weighing piglets prior to and after suckling.) In addition, there is currently no existing milking machine designed to attach to around a dozen teats and extract milk for fifteen seconds. Finally, pigs, unlike cows, cannot become pregnant while lactating, which makes a pig milk operation even less viable.

Pig milk is generally considered unappealing for human consumption. Compared to more conventional animals such as dairy cattle or goats, a main issue is their cleanliness and diet. Also, the flavor of pig milk has been described as "gamy", more so than goat's milk. The milk is also considered more watery than cow's milk.

Cheese produced from pig milk has been described as having a flavor of pig milk that is concentrated and intensified. Chef Edward Lee prepared a ricotta cheese from pig milk, which he described as "delicious".

A Dutch farmer produced one of the first experimental pig milk cheeses. As many as ten people worked to milk the sows for dozens of hours. Several of the attempts to produce cheese failed. Finally, they managed to make a few pounds. It was reported to taste "chalky and a little bit salty" and compared to other cheeses "saltier and creamier, yet grainier". The cheese was sold to an anonymous buyer at a children's charity for $2,300 per kilogram. The price fetched was higher than the most expensive variety known as pule cheese, which is made from the milk of the Serbian Balkan donkey.
