Abstract

The invention belongs to the technical field of feed additives, and discloses a feed additive for promoting growth and intestinal development of livestock and poultry, and a preparation method and application of the feed additive, aiming at improving the structure of intestinal flora of livestock and poultry, overcoming the adverse effects, caused by antibiotics, on the growth of livestock and poultry, and promoting the healthy growth of livestock and poultry. The feed additive is prepared from head cabbage slurry and solid bacillus subtilis according to a mass ratio of 500 to (1-3); the feed additive is prepared by adding 0.2-0.6g of the solid bacillus subtilis into every 100g of the head cabbage slurry, and evenly mixing; when being used as an additive for livestock and poultry feed, 10-40g of the feed additive is added into every 1000g of the feed. The feed additive is wide in material source, adequate in nutrients and high in digestibility and utilization rate; when being used as the additive for the livestock and poultry feed, the feed additive can improve the palatability of the feed, adjust the microcosmic ecological balance of animal intestines, promote the growth and intestinal development of livestock and poultry and reduce the breeding cost, thus laying a foundation for improving the resource utilization of vegetable in livestock production.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive for promoting the growth and intestinal tract development of livestock and poultry, its preparation method and application. Background technique [0002] In recent years, in order to promote the growth of animals and maintain the health of livestock and poultry, many breeding enterprises have abused and overused antibiotics and chemical drugs. As a result, the drug residues in animal products are too high, causing adverse effects on the health of consumers. Therefore, Seeking effective, safe, green and natural feed additives to replace antibiotic products has become an inevitable trend in the development of the livestock and poultry industry. [0003] As a potential substitute for antibiotics, probiotics have many advantages, for example, they can overcome various disadvantages such as endogenous infection or superinfection in animals caused by the abuse of...
