Problems solved by technology

However, such progress has been accompanied by a series of problems: pigs' physical fitness and adaptability have declined, and they are prone to stress syndrome, resulting in a decline in pork quality
Compared with the disadvantages of long cycle and slow effect of genetic breeding regulation, reasonable nutritional regulation is a more realistic solution to pork quality problems and a widely used technical means

Abstract

The present invention discloses a feed additive for pigs and a preparation method thereof. The additive comprises the raw materials of tea residues, straw, rapeseed meal, mixed microorganism strains,a pH adjuster, soybean powder phospholipid, sodium chloride and oligosaccharide. The preparation method is as follows: firstly, the mixed microorganism strains are subjected to enlarged cultivation ona PDA medium; then a microorganism suspension is mixed with the tea residues, straw and rapeseed meal; the mixture is cultured; then the pH adjuster, soybean powder phospholipid, sodium chloride andoligosaccharide are added to fermentation liquid; and the materials are mixed to obtain a finished product. The tea residues, straw and rapeseed meal are subjected to mixed fermentation with the mixedmicroorganism strains; and then the fermented materials are mixed with the soybean powder phospholipid and oligosaccharide to prepare the feed additive. The feed additive can promote animal growth, reduces feed conversion ratio and also improves animal immunity.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a pig feed additive and a preparation method thereof. Background technique [0002] For a long time, pork has occupied an important position in the dietary structure of Chinese residents. After years of reform, my country's pig industry has achieved great development in the market economy, and gradually established and consolidated my country's status as a major pig producer. With the improvement of living standards, people have gradually changed the concept of pork consumption: safe, nutritious and high-quality pork products are the first choice. In recent years, the pig breeding work has always adhered to a central goal, that is, to continuously increase the growth rate of pigs, while taking into account the reduction of pig body backfat thickness and increase carcass lean meat percentage. Therefore, domestic pig raising enterprises have introduced a large number of...
