Betaine can be used as a feed additive to improve intestinal health. Unfavorable factors such as heat stress can lead to poor intestinal elasticity in animals. When the ambient temperature rises, blood will preferentially flow to the skin to facilitate heat dissipation. This leads to a reduction in blood flow to the gastrointestinal tract, which in turn affects digestion and reduces the digestibility of nutrients.

Stress can cause changes in the intestinal structure of growing pigs, if there's no further control, it will reduce the intestine function. Betaine has beneficial effects on the intestinal structure and immune system of animals. Its beneficial effect on maintaining the integrity of the animal's intestinal tract, it can protect the animal from dehydration caused by coccidiosis or the proliferation of other undesirable microorganisms in the intestinal tract.

Research shows that the mixed use of betaine and ionophore anticoccidial drugs can significantly reduce the risk of coccidia infection in animals, and then improve their growth function and resistance. Especially for piglets, adding betaine in their feed can improve both intestinal function and prevent diarrhea, and increase feed intake, which has outstanding practical value. In addition, adding betaine in the feed can alleviate the stress response of the piglets, and then improve the feed intake and growth rate of the weaned piglets.
