Compound betaine is one of the betaine series products. It is a very mature feed additive used at home and abroad, mainly used in the feed industry. Betaine, also known as trimethylglycine, is an efficient methyl donor and a new feed growth promoter for livestock, poultry and aquatic animals. Because the ph value of compound betaine is neutral, it will not react with other feed materials when used in feed, so it is the most widely used betaine product in recent years.

Compound betaine is a highly effective, high-quality, economic, and widely used in livestock, poultry and aquaculture as a nutritive additive to induce food and promote growth. Betaine is a nutritional additive that can be used in livestock, poultry, aquatic products and various pet animal feeds. It is made of liquid betaine adsorbed on the carrier through special process and compounded and dried. It tastes sweet and has the same function as anhydrous betaine. The main uses are as follows:

1. Provide methyl as a methyl donor. High-efficiency methyl donor can partially replace methionine and choline chloride and reduce feed cost. The methyl supply efficiency of 30% compound betaine is approximately equal to that of methionine.
2. It has food inducing activity. Compound betaine can stimulate animals' sense of smell and taste, promote animal feeding, and improve the palatability and utilization of food. Increasing feed intake and daily weight gain are the main attractants of aquatic food. It is an ideal food attractant for fish and crustaceans. It has a strong attraction for fish's sense of smell, greatly increasing food consumption and promoting growth; It can also improve the feeding rate of piglets and promote their growth.
3. Participate in fat metabolism and promote protein synthesis. Adding betaine hydrochloride to pig feed can increase the area of eye muscle, reduce the average thickness of pig back fat, and improve lean meat rate and carcass quality. Adding in chicken feed can improve the carcass quality and breast muscle quantity of broilers, reduce the abdominal muscle deposition, and reduce the feed meat ratio
4. Protect vitamins. Compound betaine does not destroy the vitamins in feed, and betaine hydrochloride in premix and concentrate has certain protective effect on the stability of VA and VB, improving the use effect.
5. Betaine products are buffer substances for osmotic pressure shock. When the osmotic pressure changes sharply, betaine can effectively prevent the loss of cell water, improve the function of NA/K pump, improve the tolerance of objects to water shortage, high temperature, high salt and hypertonic environment, stabilize the enzyme activity and the function of biological macromolecules, so as to regulate the water ion balance of animal intestines, maintain the intestinal function, and slow down the occurrence of diarrhea.
