pigs have no tripe. Louvre refers to the double flap stomach of cattle and sheep, which is the third part of the stomach. Its volume is slightly larger than that of the honeycomb stomach, and there are page-like folds on the inner wall, commonly known as "louver". As we all know, cows have four stomachs, while pigs, like humans, have only one stomach, and there is no double stomach. We call the pig's stomach "belly", which is flat, not louvered, so the pig has no louvered hairy belly.
