The Magical Use and Precautions of Vitamin C in Pig Production
Vitamin C, also known as ascorbic acid, is one of the most commonly used drugs in pig production. It is white crystal or crystalline powder, soluble in water and acidic, can be used alone or in combination with other drugs, can increase the resistance of pigs to infectious diseases; promote wound healing, participate in the generation of intercellular substance and oxidation in vivo Reduction reaction, has detoxification ability, and can also promote the absorption of iron in the intestine.
1. Anti-stress effects:
During the growth process of pigs, they have to experience various stresses, such as environment, sudden changes in climate, transportation, tooth clipping, tail docking, castration, feed changes and other stresses, which will affect the synthesis and utilization of ascorbic acid in pigs, resulting in Vitamin C deficiency in pigs can lead to a decrease in feed intake in mild cases, or lead to diseases in severe cases. Adding 20 mg to 50 mg of vitamin C per kilogram of feed can effectively alleviate various stresses and reduce the incidence of pigs.
2. The effect of heatstroke prevention and cooling:
During heat stress, adding vitamin C to the feed can reduce the capillary permeability of the body, prevent the body's metabolism and heat production from being too high, enhance the body's adaptability to high temperature, benefit the growth and development of pigs, and reduce the risk of pigs under high temperature. morbidity and mortality.
Adding a large amount of antioxidants such as vitamin C and vitamin E to pigs under heat stress conditions can help the animals resist the heat stress damage of the body, thereby reducing the damage caused by heat stress. When the temperature exceeds 34°C, add 300-500 mg vitamin C.
3. Improving the immunity of pigs:
Vitamin C is an essential nutrient for the normal function of the immune system of pigs. White blood cells are rich in vitamin C. When the body is infected, the vitamin C in white blood cells will decrease sharply. Vitamin C can increase the chemotaxis and deformation of neutrophils ability, improve bactericidal ability, promote the production of lymphocytes, participate in the synthesis of immune proteins, and promote the production of interferon. Regular addition of vitamin C to the feed will play a great role in improving the immunity of pigs.
4. Enhance the body's disease resistance
A large amount of vitamin C can promote antibody production, enhance leukocyte phagocytosis, enhance liver detoxification ability, improve myocardial and blood vessel metabolism, and have anti-inflammatory and anti-allergic effects. In the prevention and treatment of infectious diseases, adding vitamin C to the feed can strengthen the body's resistance to diseases, shorten the course of the disease and reduce death.
During the recovery period after the disease, the pigs need a lot of nutrition and vitamins to repair due to the trauma of the disease. At this time, the pigs are seriously lacking in vitamin C, and some can even cause scurvy. Add 0.02 to the feed. % vitamin C can enhance the disease resistance of the pig body.
5. Prevention and treatment of pig anemia and hemostasis
Vitamin C also has reducing properties, so it plays an important role in the metabolism of metal ions. Vitamin C can reduce the unabsorbable ferric iron in the feed to ferrous iron, promote the intestinal absorption of iron, and improve the liver's ability to absorb iron. Improves iron utilization and helps treat iron deficiency anemia. In addition, supplementing vitamin C can reduce the permeability and fragility of capillaries, so as to achieve the purpose of hemostasis. Clinically, pigs suffer from swine dysentery, adding vitamin C will improve the hemostatic function, shorten the recovery period after infection, and reduce mortality.
1. It can destroy vitamin B12 in the feed, complex with copper and zinc ions in the feed, and affect its absorption.
2. This product is acidic and alkaline, and it is easy to oxidize and lose effect when used in combination; if the injection contains sodium bicarbonate, it is easy to form calcium carbonate precipitation with trace calcium, and it cannot be mixed with calcium preparations for injection.
3. Compatibility with solutions such as vitamin K3, vitamin B2 and iron ions may affect the efficacy of the medicine, so it is not suitable for compatibility.
4. Under various stress conditions, such as high temperature, physiological stress, transportation, feed change, disease, etc., not only the ability of animals to synthesize vitamin C is reduced, but also the demand for vitamin C in pigs is also increased.
