no, although pigs are a part of the livestock they do not need to chew cud. this is becaue they only have one stomach whareas animals such as sheep goats and cows chew cud this is because there stomach consists of four diffrent chambers.
Kosher animals have to have split hooves and chew their cud. A pig does not chew its cud. Leviticus 11:7 "And the pig, because it has a cloven hoof that is completely split, but will not regurgitate its cud; it is unclean for you."
Sheep are ruminants and they chew their cud (which is grass they have eaten that has been slightly digested in the rumen and they cough it up to rechew it) to make the particle size smaller so that it is more easily digested by the microbes in their gut.
Cud is regurgitated food mostly in cattle that chew it up again and again to break down hay, grain, etc. Animals that chew their cud include cattle, goats, sheep, giraffes, bison, yaks, water buffalo, deer, camels, alpacas, llamas, wildebeest, antelope, pronghorn, and nilgai.
fur these animals have many, many differences. one, they are not even in the same order. goats have cloven feet, unlike horses. horses do not chew their cud. and there is also the size difference. goats have horns. these are just some of the differences.
