Betaine

In the animal metabolic system, betaine serves as a highly efficient methyl donor, with a methyl content 2.3 times that of choline chloride, which can significantly reduce the amount of methionine added. Experimental data shows that replacing 30% methionine with betaine in broiler feed can reduce feed costs by 12-15 yuan per ton while maintaining production performance. In aquaculture, its osmotic protection function is more prominent, which can increase the survival rate of South American white shrimp by 23% in salt mutation environments.
