Feed additives refer to various trace substances added to the compound feed. These trace substances are substances that are high in the growth rate of broilers and are generally lacking in feed. These additives are mainly the following. Vitamin Additives The broiler special vitamin supplement should be used in the production. The dosage can be referred to the recommended dosage on the manufacturer's instruction manual, generally 0.02%-0.05%, but the diet composition, environmental conditions (temperature, feeding method, etc.), disease, transportation should be considered. In the case of transplanting, vaccination, etc., the amount of vitamin added in chickens under these adverse conditions may be appropriately increased (for example, by about 1 time). Trace element additive The trace elements that need to be added often include copper, zinc, selenium, manganese, etc. These elements often use salts as additives. The amount of additives in the diet is small, generally 0.01%-0.1%. Corn or flour is often used as a diffusing agent. Therefore, attention should be paid to mixing evenly. Coloring additive The role of these additives is to meet the market's need for high-quality broiler skin yellowing, which can be added to the skin to deepen the skin color. Commonly used synthetic carotenoids to supplement the deficiency of lutein in the feed, the amount of addition is generally 2-10 grams per ton of feed. Due to the large variety of coloring additive products on the market, farmers should pay close attention to whether the coloring additives used are harmful to the human body in production. Amino Acid Additives The amino acids added to the feed are mainly the most essential amino acids in the plant feed, and the main additives are synthetic lysine and methionine. The dosage added is generally from 0.02% to 0.05%. Antioxidant Because high-quality broiler feed contains more oil, during the storage process, the oil and fat-soluble vitamins will be automatically oxidized and the feed will be degraded. Therefore, when storing high-quality broiler feed for a long time, it is necessary to add antioxidants to the compound feed. . The role of the anti-fungal agent is to prevent the mildew and deterioration of the feed during the high temperature and humid season.
