Although these additives do not contain the nutrients needed by chickens, they have great benefits in promoting the growth and development of chickens, increasing the egg production rate, and enhancing disease resistance and feed storage. Its types include antibiotic additives, insect repellent health additives, antioxidants, antifungal agents, Chinese herbal medicine additives and hormones, enzyme preparations and so on. Antibiotic additives Antibiotics have antibacterial effects. Some antibiotics, when added as dietary supplements, can inhibit the activity of harmful bacteria in the gut of chickens, have resistance to various respiratory and digestive diseases, increase feed utilization, and promote the effect of weight gain and egg production. The effect is even more pronounced when the chicken is in adversity. Commonly used antibiotic additives include penicillin, oxytetracycline, chlortetracycline, neomycin, and tylosin.

Antioxidants In the process of feed storage, adding antioxidants can reduce the loss of vitamins, fats and other nutrients, such as adding 200 grams of mountain quinoline per ton of feed, storage for one year, loss of carotene 30%, without the loss of antioxidants 70 %; The addition of antioxidants to fat-rich fish meal can maintain the original crude protein digestibility, and the efficiency of digestion, absorption and utilization of various amino acids is not affected.

Anti-mould agent In the process of feed storage, in order to prevent the feed from becoming moldy and deteriorating, and maintain good palatability and nutritional value, antifungal agents can be added to the feed. The commonly used anti-mold agents include sodium propionate, calcium propionate, sodium dehydroacetate, and glacier. The added amount is: 1 kg of sodium propionate per ton of feed; 2 kg of calcium propionate per ton of feed; 200 g to 500 g of sodium dehydroacetate per ton of feed. Yolk color enhancer After adding the egg yolk color enhancer to the feed, the egg yellow color can be improved, that is, the color of the egg yolk changes from pale yellow to dark yellow. Commonly used egg yolk color enhancers include lutein, lukangding, and red pepper powder. For example, add 200 grams to 300 grams of red pepper powder per 100 kilograms.
