Did you order this tripe or that tripe?

1 Grass tripe, golden tripe, and hair tripe (beef tripe) are respectively the rumen, reticulum, and omasum (double stomach) of the cow.

2 The rumen is an important place for ruminants to digest food, but the rumen of a newly born ruminant is very small. For example, the rumen of a newborn calf is less than one-third of the size of the four stomachs. However, the rumen grows and develops very quickly, and the rumen size of an 18-month-old cow basically reaches the adult level (about 85% of the size of the four stomachs).

3 The rumen epithelium can effectively absorb Na+, K+, Cl- and other ions, and the absorption of volatile fatty acids is as high as 75%.

4 Volatile fatty acids (mainly acetic acid, propionic acid and butyric acid) are the main end products of carbohydrate metabolism in the rumen. They are absorbed into the blood circulation through the rumen epithelium and can be used as energy substances and complete important biosynthetic functions.
