THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The main digestive enzymes in cattle are salivary and pancreatic lipase, rennin, pepsin, trypsin, lactase and amylase. Maltase and isornaltase, celliobiase, trehalase, elastase and carboxypeptidase are also present.

Detailed explanation-2: -Saliva aids in chewing and swallowing, contains enzymes for breakdown of fat (salivary lipase) and starch (salivary amylase), and is involved in nitrogen recycling to the rumen. Saliva’s most important function is to buffer pH levels in the reticulum and rumen.

Detailed explanation-3: -The reticulum traps things the cow shouldn’t have eaten, such as bits of metal or rocks. In the reticulum, the food also mixes with saliva to produce small wads of food called cud. Cows regurgitate these bits of cud back into their mouths, where they then chew them completely.
