Chickens with VC added to their feed had significantly less mortality and more weight compared to those without VC. In production practice, if given a preventive amount of VC can reduce the adverse effects on chickens in different stress states such as high temperature, high humidity, sudden interruption of feed and drinking water, immunization, disease, feather change, beak break, capture, noise, and house move. Therefore, in the cold winter season, the appropriate amount of vitamin C supplementation to chickens can significantly reduce the morbidity of chickens.

Currently, the incidence of leg weakness in broiler chickens has been greatly increased. It is believed that the main reason for this is the difference between fast muscle growth and slower bone development in modern breeders. The resulting economic losses can be as high as 15% of the total harvest. In a basic study VC was added to a VC-free diet in groups, with levels gradually increasing from zero to 2560 IU/kg. each group was fed the diet alone or supplemented with VC. blood samples were collected and tibia and toe bones were taken for analysis between 21 and 28 days of age, and VC increased the binding capacity of duodenal calcium binding by 50%, so that the addition of vitamin C at the time of chicks can promote bone formation.

For the treatment of chicken colds, if a large dose of vitamin C and E is added, it can effectively protect the ovarian follicles, fallopian tube mucosal epithelium and various tissues and cells of the body from the damage of oxidized free radicals produced in the body under pathological conditions, and reduce the appearance of follicular liquefaction. It can play an excellent role in the treatment and recovery of later laying eggs. Suggestion: Adding vitamin C during the treatment of chicken illness will not only help the recovery of the disease, but also help the recovery of the fallopian tubes and ovaries in the later stage.

When drug poisoning occurs in poultry, using glucose plus VC as drinking water, mixing or intravenous injection can greatly reduce the permeability of capillary wall and protect liver function. At the same time, it can strengthen the filtration and reabsorption function of the glomerulus, so that the toxins can be excreted out of the body.

Parasitic diseases in chickens can affect the synthesis of VC in chickens. At the same time, the worms also secrete toxins to poison the body and cause different degrees of metamorphosis or stress in chickens. If the treatment is supplemented with Vc, it can strengthen the anthelmintic effect of the drug and the tolerance of the body to the anti-parasitic drug, thus making the body recover faster.
