Vitamin C, also known as ascorbic acid, is a white or slightly yellowish crystalline powder that is easily soluble in water and is mainly found in some green feed. According to the author's experience and experience in the treatment and treatment of veterinary hospitals in Xingtai City, Hebei Province, the application of vitamin C in pig production is briefly described below.
The anti-stress effect of vitamin C
Feeding 20 to 50 mg of vitamin C per kilogram of feed can effectively reduce stress and reduce the chance of developing herds to ensure healthy growth.
Anti-allergic stress
Environmental stress, pathological stress, and nutritional stress all influence the synthesis and utilization of ascorbic acid in pigs, resulting in deficiency of vitamin C in pigs, ranging from light to low intake and heavy drinking, and to severe disease. The lack of vitamin C causes pig disease. Even deaths are common occurrences in production. Therefore, adding vitamin C to the feed can make the pigs grow healthily.
Heat Stress During heat stress, adding vitamin C to the feed can reduce the capillary permeability of the body, enhance the body's resistance to disease, reduce hepatic steatosis, and reduce mortality. Addition of vitamin C in the feed can increase serum auxin levels in the pig's body, increase body weight, and improve immune function. Vitamin C can also reduce the effect of toxic substances and relieve allergic diseases. Therefore, vitamin C can make the body's metabolism and heat production at high temperatures not too high, enhance the body's adaptability to high temperatures, is conducive to the development of pig growth, reduce pig morbidity and mortality at high temperatures.
Vitamin C can enhance the immune function of pigs
During the growth of pigs, especially at the sub-pig stage, immunity is frequent and sometimes the immune potency is significantly reduced once the stress is encountered. Adding vitamin C to the feed not only improves the immune effect of stress factors on pigs, but also slows the immune suppression caused by high temperatures. In the production practice, pigs are immunized while vitamin C is added to the feed and the immune effect is increased.
Vitamin C promotes growth
With the increasing level of pig industry, adding 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 rearing stage of pigs, commonly used amount of vitamins Feeding with C mix can make the pig grow evenly, reduce the emergence of stiff pigs and increase the survival rate.
Vitamin C can improve the reproductive performance of pigs
Adding vitamin C to the feed can significantly improve the semen quality of the breeding boar and increase the sow production rate, which has a satisfactory effect on the promotion of breeding pig production. Because vitamin C regulates the metabolism of calcium, promotes calcium absorption and utilization, and increases sperm formation and semen volume, adding vitamin C can increase fertilization rate, birth rate, and pig quality.
The role of vitamin C in the prevention and treatment of diseases
In addition to vitamin C used in the prevention and treatment of scurvy, it is also commonly used in the treatment of various infectious diseases of pigs, fever and trauma or burns, in order to enhance the body's resistance to disease and promote wound healing.
When the tail bleeding is given to the pig, vitamin C is added to the feed to reduce bleeding and promote wound healing. In addition, vitamin C supplementation can reduce capillary permeability and brittleness, so as to achieve the purpose of hemostasis. In the clinical case of coccidiosis in pigs, adding vitamin C can improve hemostatic function, shorten the recovery period after infection, and reduce mortality. In the treatment of fresh wounds, in addition to conventional treatment, the injection of vitamin C into the wound and wound cavity, and then covered with a layer of gauze moistened with vitamin C injection, is conducive to wound healing.
Diagnostic reagents can be divided into two categories: in vivo diagnostic reagents and in vitro diagnostic reagents. It is mostly a reagent for detection by the reaction between antigen and antibody.
A: Classification of in vitro diagnostic reagents:
1. In vitro biodiagnostic reagents managed as drugs include:
1. Blood type and tissue type reagents;
2. Microbial antigen, antibody and nucleic acid detection reagents;
3. Tumor marker reagents;
4. Immunohistochemistry and human tissue cell reagents;
5. Human genetic testing reagents;
6. Biochips;
7. Allergy diagnostic reagents.
2. In vitro reagents managed as medical devices include:
1. Clinical basic test reagents;
2. Clinical chemistry reagents;
3. Blood gas and electrolyte determination reagents;
4. Vitamin determination reagents;
5. Cell histochemical stains;
6. Autoimmune diagnostic reagents;
7. Microbiological test reagents.
B: According to medical test items, clinical diagnostic reagents can be roughly divided into clinical chemical test reagents, immunology and
Serological testing reagents, hematological and cytogenetic testing reagents, microbiological testing reagents, body fluid excretion
Detection reagents, genetic diagnosis reagents, etc. Among them, the market share of clinical chemistry
The largest, close to 34%; followed by the immunology market, accounting for about 29%. Novel immunodiagnostic reagents and genetic diagnostic tests
The reagent was developed in the late 1980s, and it is the most common diagnostic reagent for all current diagnostic reagents, regardless of technology or market.
The fastest growing product.
