Non-antibiotic daily ration feed additive premix for broiler chickens and usage method

The invention relates to non-antibiotic daily ration feed additive premix for broiler chickens. The non-antibiotic daily ration feed additive premix for the broiler chickens is composed of 10-20% of curcumin, 5-15% of xylooligosaccharide, 5-15% of bacillus licheniformis and 50-80% of carriers. A usage method of the non-antibiotic daily ration feed additive premix for the broiler chickens comprises the step that when broiler chicken feed is prepared, the non-antibiotic daily ration feed additive premix for the broiler chickens and the feed are mixed or evenly stirred according to the proportion of 1:1000. According to the non-antibiotic daily ration feed additive premix for the broiler chickens and the usage method, the composite effect of the curcumin, the xylooligosaccharide and the bacillus licheniformis is used to regulate the organism immunity and disease resistance of the broiler chickens, improve the egg laying productivity of the chickens and stimulate the growth potential of the chickens, and the significant effects are achieved. Animal tests prove that the premix can effectively replace antibiotics, the toxic and side effects such as the drug resistance and drug residues which occur after the antibiotics are used for a long time are avoided, and the healthy sustainable development of breeding industries and feed industries is facilitated.
