Application of Vitamin C in Pig Production
Vitamin C is one of the most commonly used drugs in pig production. Can be used alone or in combination with other drugs, can increase the body's resistance to infectious diseases; promote healing of wounds, participate in the formation of cell mesenchyme and redox reactions in the body, has the ability to detoxify, but also promote the absorption of iron in the intestinal tract .
1. Anti-stress
During the growth of pigs, various kinds of stress, such as changes in the environment, climate, transportation, etc., affect the synthesis and utilization of ascorbic acid in pigs, resulting in deficiency of vitamin C in pigs. The occurrence of disease. Adding 20-50 mg of vitamin C per kilogram of feed can effectively relieve various stresses and reduce the chance of developing herds.
2. Improve immunity
Vitamin C is a nutrient necessary for the pig's immune system to perform its normal functions. White blood cells are rich in vitamin C. When the body is infected, the vitamin C in leukocytes will be drastically reduced. Vitamin C may increase the chemotaxis and deformation of neutrophils. Ability to improve bactericidal capacity, promote the production of lymphocytes, participate in the synthesis of immune proteins, and promote the production of interferon. The regular addition of vitamin C to the feed will play a large role in improving the immunity of the herd.
3 enhance the body resistance to disease
A large amount of vitamin C can promote the production of antibodies, enhance the leukocyte phagocytosis and increase 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 the disease and shorten the duration of the disease and reduce death. During the recovery period after the illness, the pigs need a lot of nutrition and vitamins to repair due to the trauma of the disease. At this time, the pig's body is seriously deficient in vitamin C, and some can even cause scurvy, adding 0.02% to the feed. Vitamin C can increase the body resistance of pigs.
4. Anti-anemia and hemostasis
Vitamin C is also reducing, so it plays an important role in the metabolism of metal ions. Vitamin C can make the non-absorbable ferric iron in the feed reduced to divalent iron, promote the absorption of iron in the intestinal tract, and improve the liver. The utilization of iron can help treat iron deficiency anemia. In addition, vitamin C supplementation can reduce capillary permeability and brittleness, so as to achieve the purpose of hemostasis. Clinically, pigs suffer from swine dysentery. Adding vitamin C can improve hemostatic function, shorten the recovery period after infection, and reduce mortality.
5. Raise the birth rate
Sows during pregnancy, vitamin C can be synthesized in pigs, and can meet the needs, but in heat stress, environmental stress, disease stress and other states, vitamin C synthesis decreased blood content, affecting litter size rate. When vitamin C is added in a timely manner, 150-200 grams of vitamin C per ton of feed is added to prevent the production of weak piglets and increase the survival rate of piglets.

Sodium fluoride is a weakly potent anticoagulant that is often used in combination with potassium oxalate for blood glucose testing. It contains sodium fluoride or potassium oxalate or EDTA-NA spray, which can inhibit the activity of enolase in glucose metabolism. After blood is drawn, it is mixed reversely 5-8 times, and after centrifugation, the supernatant plasma is taken for use. It is a special tube for the rapid determination of blood glucose.
