Why is there no pig's milk cheese?
Cows don't lactate without giving birth.
I would suppose that a sow would continue to give milk if she were milked regularly. I think it could be done if somebody really wanted to. I will leave the opportunity to others.
Anybody remember the Simpson's episode where Fat Tony had a room full of rats hooked up to milking machines to supply Springfield elementary school?
This has been previously discussed on CH:
Even if you could get a sow to cooperate with being milked, it would be extremely difficult to do it. Sows have many tiny teats, too small for human hands or a mechanical milker to grasp onto. A single teat gives a small quantity of milk, so it would be necessary to extract the milk from all of them to get enough. The time needed and the cost of labor wouldn't make it worthwhile.
Beyond this, the composition of pig's milk makes it a poor candidate for cheesemaking. It doesn't contain the short-chain fatty acids that are so important to the development of flavor in cheese. It's also unclear if there is a suitable rennet that will coagulate the milk. Some animal milks do not coagulate easily.
Someone wrote an article on the Internet claiming that a family in Tuscany makes a rich cheese from pig's milk and that he was invited to taste it. He wouldn't reveal anything about the whereabouts of this alleged cheesemaking operation. I'm not convinced that this isn't a hoax. He did suggest a great name for the cheese: Porcherino.
Mrs Oink Jones is not a warm and fuzzy kind of girl and a low milk producer.
It isn't unheard of for the sow to eat part of a new born litter,even her own.This is an omnivore that if you take away the modern factory of pork production,will eat anything,plant or animal.Remove the factory,ring and electric fence you have an animal fierce,formidable enough to be almost predator proof.
