Allicin is an antibacterial substance, which can inhibit the growth and reproduction of dysentery bacilli, typhoid bacilli and Vibrio cholerae. It has obvious inhibition and killing effect on Staphylococcus, Streptococcus and pneumococcus, so it can reduce the incidence rate of chicken and fish. Adding a small amount of allicin to the feed of chickens, ducklings and layers can improve the survival rate of livestock chickens and ducklings and the laying rate of layers. Adding allicin to broilers and ducks can improve the feed utilization rate by 6% - 16%, improve the feed palatability, stimulate oral taste buds and increase animal feed intake. Allicin can improve the flavor of chicken and duck. For fish, allicin is mainly used for disease prevention, treatment and good food attractant. At the same time, it can also combine the added vitamin B1 with garlic thiamine to prevent the decomposition of vitamin B1 by vitamin B2 decomposition enzyme in live bait (FISH). Garlic thiamine has the same effect as vitamin B1, but its absorption is better than vitamin B1 and its physiological effect is better. Therefore, allicin can also prevent fish vitamin B1 deficiency, reduce feed coefficient and promote fish growth.
