Vitamin C (vc), also known as ascorbic acid, is a white or slightly yellowish crystalline powder that is readily soluble in water. Nature is mainly found in some green feeds. Pigs can synthesize themselves and are generally not lacking. However, as the intensification of the pig industry continues to increase, with a slight stress factor, the body's vitamin C is obviously insufficient, and even there will be deficiency. Therefore, in the practice of modern pig raising, artificial addition of vitamin C has become the basic common sense of pig farmers. After adding vc, sometimes you will get unexpected results. According to the experience and experience of the author in the Xingtai City Veterinary Hospital for many years, the application of vitamin C in pig production is briefly described below. 1 anti-stress effect of vitamin C Adding 20-50 mg of vitamin C per kilogram of feed in the feed can effectively resist stress and reduce the chance of disease in the herd to ensure its healthy growth. 1.1 against all kinds of bad stress Environmental stress, pathological stress and nutritional stress can affect the synthesis and utilization of ascorbic acid in pigs, which leads to the lack of vitamin C in pigs, but reduces the consumption of food, and reduces the risk of disease. The disease is caused by the lack of vitamin C. Cases of morbidity and even death are common in production. Therefore, in the case of adverse stress, it is necessary to add vitamin C to the feed in order to make the pigs grow healthily. 1.2 anti-heat stress During heat stress, the addition of vitamin C to the feed can reduce the capillary permeability of the body, enhance the body's disease resistance, reduce hepatic cell steatosis, and reduce the rate of death. The addition of vitamin C to the feed can increase the auxin content in the serum of the pig and increase the body weight. It can also improve immune function, vitamin C can also reduce the role of toxic substances, alleviate allergic diseases. Therefore, vitamin C can make the metabolism and heat production of the body at high temperature not too high, enhance the body's adaptability to high temperature, help the development and growth of pigs, and reduce the morbidity and mortality of pigs under high temperature. 2 vitamin C can enhance the immune function of pigs Now the pig's life, immunization is frequent, especially in the piglet stage, it is more immune, sometimes once the stress is encountered, the immune titer is significantly reduced. 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, vitamin C is added to the feed, and the immune effect is indeed increased. 3 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. Promote the growth of the body, especially in the feeding stage of piglets. Usually, the appropriate amount of vitamin C is used to feed the baby, which can make the piglets grow evenly, reduce the appearance of stiff pigs and increase the survival rate. 4 vitamin c can improve the reproductive capacity of pigs The addition of vitamin C to the feed can significantly improve the quality of the semen 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, it promotes the absorption and utilization of calcium. Increase sperm formation and semen volume, so adding vitamin C can improve fertilization rate, litter size and piglet quality. 5 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 infectious diseases of pigs, treatment of high fever, trauma or burns to enhance the body's disease resistance and promote wound healing. 5.1 Hemostasis When the piglet is broken, 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 hemostasis. Clinically, when coccidiosis occurs in pigs, adding vitamin C will improve hemostasis, shorten the recovery period after infection, and reduce mortality. When treating fresh wounds, in addition to conventional treatment, the vitamin C injection is sprayed into the wound and the wound cavity with a syringe, and then the wound is covered with a layer of gauze with vitamin C injection, which is beneficial to the healing of the wound. 5.2 Detoxification Vitamin C has strong reducibility, protects the sulfhydryl group of the enzyme system from poisonous damage, promotes antibody formation, protects liver function, and strengthens liver detoxification. When clinically occurring arsenic, mercury, lead and other chemical poisoning, the use of vitamin C, has a significant role in assisting detoxification, has a certain auxiliary repair effect on damaged liver cells. 5.3 Enhance the body's disease resistance In the prevention and treatment of infectious diseases, the addition of vitamin C in the feed can improve the body's response to vaccines and drugs, strengthen the body's resistance to disease, and shorten the course of disease to reduce death. In the recovery period after the disease, the pigs need a lot of nutrients and vitamins to repair due to the trauma of the disease. At this time, the pig body is seriously deficient in vitamin C, and some can even cause ring blood disease, adding 0.02 to the feed. % of vitamin C can enhance the disease resistance of pigs. 5.4 Improve the birth rate During the pregnancy, vitamin C can be synthesized in pigs and can meet the needs, but in the state of heat stress, environmental stress, disease stress, etc., the amount of vitamin C synthesis decreases, the blood content decreases, affecting the birth rate. Adding vitamin C in time, adding 150-200 g of vitamin C per ton of feed can prevent weak piglets and increase the survival rate of piglets.
