The invention discloses a broiler feed. The formula according to the weight ratio is as follows: corn 590-690, soybean meal 243-285, wheat 70-80, cotton meal 9-24, calcium hydrogen phosphate 4.9-5.2, calcium powder 9-11, lysine Acid 3.2-3.8, Choline Chloride 0.7-1.2, DL-Methionine 1.4-1.5, Phytase 0.12-0.15, Threonine 0.07-0.09, Sodium Chloride 2.5-3, Biological Additives 2.8-4.7. The advantages of the present invention are: the biological additives are lactic acid bacteria, Bacillus subtilis, mannose oligosaccharides for feed, and compound enzyme preparations, which will not cause the problem of drug resistance, and are green and pollution-free additives. The use of biological additives can overcome the effect of antibiotics on the digestive tract. The adverse effects of other beneficial microbial flora, avoiding the toxic side effects, drug resistance and drug resistance of long-term use of antibiotics, reducing drug residues in livestock and poultry products, improving the quality of livestock and poultry products, and reducing drug residues on human health and life safety threat. |
