The addition of betaine in rabbit feed can promote fat metabolism , avoid fatty liver, resist stress, and improve immunity. At the same time, it has the effect of improving the stability of fat-soluble vitamins A, D, E, and K.

Betaine promotes the composition of phospholipids in the body, on the one hand, it reduces the activity of fat-forming enzymes in the liver, on the other hand, it promotes the composition of apolipoproteins in the liver, promotes the migration of fat in the liver, and reduces the content of triglycerides in the liver. And by promoting the differentiation of fat and inhibiting the composition of fat to reduce the accumulation of body fat.

Betaine is a buffer substance for sudden changes in osmotic pressure. When the cell's external osmotic pressure changes drastically, the cells can absorb betaine from the outside to maintain the normal osmotic pressure balance and avoid the outflow of water and the intrusion of salts in the cells. At the same time, betaine can improve the potassium and sodium pump functions of the cell membrane, and can ensure the normal function and nutrient absorption of the intestinal mucosal cells. The buffering effect of betaine on the osmotic pressure surge is effective.

During the storage and transportation of feed production, most vitamins have more or less potency decline. Among the premixes, choline chloride has the greatest impact on the stability of vitamins. Betaine has strong moisturizing properties, can enhance the stability of vitamin, avoid the storage loss of vitamin A, D, E, K, B1, B6, the higher the temperature and the longer duration, the effect will be more obvious. Adding betaine to the compound feed to replace choline chloride can better maintain the vitamin titer and reduce economic loss.
