Synbiotics for feeds, feed additive containing same, and feed and application thereof

Abstract

The invention relates to synbiotics for feeds, a feed additive containing the same, and a feed and application thereof, belonging to the technical field of feed processing. The synbiotics for feeds use Lactobacillus plantarum, Enterococcus faecalis, Enterococcus faecium and Bacillus subtilis as composite probiotics and oligosaccharide as prebiotics; through synergism of the probiotics and the prebiotics, the prebiotics exert promotion effect on the probiotics, promote the growth of the probiotics and inhibit the growth of harmful bacteria, so the purpose of adjusting the microecological balance of intestinal tracts is eventually achieved; and residues are not left in animal bodies, and drug resistance is not incurred, so the problems of drug resistance and drug residues resulting from abuse of antibiotics are overcome. The feed provided by the invention has good effect on growing pigs and weaned piglings, accelerates the growth speed of bred pigs, improves the immunity of pigs and reduces the diarrhea rate and incidence rate of pigs.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a synbiotic for feed, a feed additive containing the same, feed and application thereof. Background technique [0002] In recent years, my country's pig industry has developed very rapidly, and the technical level of breeding management has also improved, but it also faces many problems in the process of pig breeding, such as: early piglets are affected by factors such as weaning, nutrition and environment, Lead to reduced feed intake, growth retardation, weight loss, diarrhea, and even death; growing pigs have low digestibility of feed, slow growth, and excessive excrement, which is easy to cause environmental pollution. [0003] In order to reduce the above problems, most of them use antibiotics in feed or direct injection. Long-term use of antibiotics will cause bacteria to develop drug resistance, and at the same time, it is easy to cause antibiotic residues in animal ...
