Abstract

The invention relates to an avian influenza resistant feed additive for large-scale ecological chicken breeding. The avian influenza resistant feed additive is prepared from the following raw materials in parts by weight: 50-120 parts of japanese metaplexis pericarp, 20-50 parts of a coarse hyperforin coarse material, 20-30 parts of astragalus membranaceus, 15-30 parts of honeysuckle and 20-30 parts of isatis root. The invention also relates to a preparation method for the feed additive. The preparation method comprises the steps of crushing the raw materials into fine powder, screening the fine powder through a 100-mesh sieve, and uniformly mixing the fine powder. The invention also relates to a use method of the feed additive. The use method comprises the steps of mixing a basic daily feed for chicken and the avian influenza resistant feed additive according to a mass ratio of (5-10):1, stirring the feed and the feed additive in a stirring machine for 120-150 minutes to obtain a mixture, taking out the mixture, and stirring the mixture in water to form paste which is used for feeding the chicken. The avian influenza resistant feed additive disclosed by the invention is used for feeding the chicken, so that the operation is easy, and the avian influenza resistant effect is outstanding.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to the technical field of poultry feed additives. Background technique [0002] At present, in the process of large-scale chicken farming, the ubiquitous problems of "two highs and one low" of low quality (product quality), high input (raising cost input), and high risk (disease risk), especially the risk of disease, have always been a problem. An important bottleneck in the development of my country's chicken farming industry. [0003] In recent years, with the continuous improvement of people's living standards, consumers have put forward higher requirements for the quality of chicken. Due to the large-scale use of antibiotics and feed additive residues and accumulation in order to solve the high risk of disease in the process of large-scale chicken raising, it has led to a series of food safety and human health problems, prompting people to start paying attention to the wa...
