Description
Vitamin C is a polyhydroxy compound with the chemical formula C6H8O6. The structure is similar to glucose, and the two adjacent enol hydroxyl groups at the 2nd and 3rd positions in the molecule are easily dissociated and release H+, so it has acid properties, also known as L-ascorbic acid.
Applications
*Anti-stress effect: add VC to the feed or drinking water 24 hours before the change of house, transportation, temperature mutation, etc., can enhance the anti-stress ability and reduce the mortality rate.
*Improve immunity：improve the effect of stress factors on animal immunity, and slow down the immune suppression caused by high temperature.
*Improve the absorption rate of calcium：Adding vitamin C can improve fertilization rate, childbirth rate and pig quality. Adding VC to feed or drinking water can promote calcium absorption, greatly improve the quality of eggshells and reduce the rate of broken eggs.
