The Role And Application Of Vitamin C In Aquaculture
Vitamin C, also known as ascorbic acid, is a white or slightly yellowish crystalline powder that is readily soluble in water and is found mainly in some greenish feeds. According to the author's experience and experience in the diagnosis and treatment of Xingtai City Veterinary Hospital in Hebei Province for many years, the application of vitamin C in pig production is briefly described below.
Anti-stress effect of vitamin C
Adding 20 mg to 50 mg of vitamin C per kilogram of feed can effectively reduce stress and reduce the chance of disease in the herd to ensure its healthy growth.
Resistance to various stressful stresses, pathological stress and nutritional stress can affect the synthesis and utilization of ascorbic acid in pigs, resulting in a deficiency of vitamin C in pigs, but a reduction in food and less, but a disease, due to lack of vitamins. Cases of C disease and even death in pigs are common in production. Therefore, the addition of vitamin C to the feed can make the herd grow healthily.
Anti-heat stress During heat stress, the addition of vitamin C to the feed can reduce the body's capillary permeability, enhance the body's disease resistance, reduce hepatic steatosis, and reduce mortality. The addition of vitamin C to the feed can increase the auxin content in the serum of the pig, increase the body weight, and improve the immune function. Vitamin C can also reduce the effects of toxic substances and alleviate allergic diseases. Therefore, vitamin C can make the body at high temperature. Metabolism and heat production are not too high, and the body's adaptability to high temperature is enhanced, which is conducive to the development and growth of pigs and reduces the morbidity and mortality of pigs at high temperatures.
Vitamin C can enhance the immune function of pigs
In the growth process of pigs, especially in the pig stage, the immunization is frequent, and sometimes the immune titer is significantly reduced once the stress is encountered. The addition of vitamin C to the feed not only improves the effects of stress factors on pig immunity, but also slows down the immunosuppression caused by high temperatures. In the production practice, while the pig is immunized, the vitamin C is added to the feed, and the immune effect is increased.
Vitamin C has a growth promoting effect
With the increasing level of the pig industry, the addition of vitamin C to the feed in the modern pig industry can alleviate the scurvy caused by the lack of ascorbic acid and vitamin K, and promote the growth of the body, especially in the pig breeding stage. Feeding the C mixture can make the pigs grow evenly, reduce the appearance of the stiff pigs and increase the survival rate.
Vitamin C can improve the fertility of pigs
The addition of vitamin C to the feed can significantly improve the semen quality of the boar, and increase the sow rate of the sow, which has a satisfactory effect on promoting the production of the pig. Because vitamin C regulates calcium metabolism, promotes calcium absorption and utilization, and increases sperm formation and semen volume, vitamin C supplementation can increase fertilization rate, birth rate and quality of piglets.
The role of vitamin C in the prevention and treatment of diseases
In addition to being used for the prevention and treatment of scurvy, vitamin C is also commonly used to control various infections of pigs and treat high fever and trauma or burns to enhance the body's disease resistance and promote wound healing.
When hemostasis is applied to the piglet, the vitamin C is added to the feed to reduce bleeding and promote wound healing. In addition, vitamin C supplementation can reduce the permeability and fragility of capillaries, thereby achieving the purpose of stopping bleeding. Clinically, when coccidiosis occurs in pigs, the addition of vitamin C can improve hemostasis, shorten the recovery period after infection, and reduce mortality. When treating fresh wounds, in addition to conventional treatment, vitamin C injection is sprayed into the wound and wound cavity, and then the wound is covered with a layer of gauze with vitamin C injection, which is beneficial to wound healing.
