1. Glucose water is given to livestock and poultry under high temperature conditions of glucose, which can reduce the mortality, increase the bred rate and increase the body weight. Generally 4% of glucose water is used.
2. Oligosaccharides Adding oligosaccharides to feed can improve feed efficiency, increase daily gain and feed intake. Common oligosaccharides mainly include fructooligosaccharides, mannooligosaccharides, oligosaccharides, and the like.
3. Sodium Bicarbonate Sodium bicarbonate neutralizes acidic substances in the blood and strengthens the body's buffering capacity. Normally supplemented with drinking water, the amount added is 0.1% to 0.2%.
4. Potassium chloride adds 60 to 80 grams of potassium chloride per kilogram of feed or drinking water, which can withstand the adverse effects of heat stress and increase production performance.
5. Vitamin C Vitamin C can ensure the stable secretion of corticosteroids, enhance the body's immune function, and participate in the immune response of cells and the body. Can be added to feed or drinking water, typically 200 mg per kilogram of body weight.
6. Vitamin E Vitamin E can promote the synthesis of immunoglobulin, enhance the activity of T lymphocytes, and improve the body's resistance to disease. Can be added to feed or drinking water, generally 200-300 mg per kilogram of body weight.
Selenium selenium has good heat stress resistance. In general, 0.33 mg per kilogram body weight is used.
8. Chromium added 0.4 mg of yeast chromium per kilogram diet can significantly reduce animal serum cortisol levels, enhance immunity, and improve livestock performance.
9. Fumaric acid fumaric acid can increase energy production, improve body resistance, but also has a sedative effect, can inhibit the central nervous system, so that hot wheezing decline. Can be added in the diet, with a dosage of 0.1%.
10. Citric acid Citric acid can be oxidized into carbon dioxide and bicarbonate in the body, can buffer acidic metabolites, and can be added to the feed in an amount of 0.1%.
11. Succinic acid succinic acid is a very good stress buffer, can be added to the feed, the amount of 1 ~ 3%.
12. Bacitracin Peptide Zinc supplements Zinc, can relieve the adverse reactions caused by heat stress. Generally, 50 mg of feed is used per kilogram of feed.
13. Flavomycin can increase feed conversion, increase nutrient absorption and improve immune function. Usually 5 mg of feed per kilogram of feed.
14. Virginiamycin Virginiamycin can increase the weight gain and survival rate of livestock and poultry under heat stress and improve feed utilization. Generally, the dosage is 15-20 mg per kilogram of body weight.
15. Assunic acid has the function of promoting protein synthesis, has a certain mitigation effect on heat stress, and has a significant effect on improving production performance. Generally, the amount of feed per kilogram is 30 to 100 milligrams.
