A feed synbiotic, its preparation method and its application in livestock and poultry breeding animal feed

Abstract

The invention discloses a symbiotic used for feeds. The synbiotic is a microcapsule structure, the core material of the microcapsule structure is mainly prepared from epilactose and lactic acid bacteria, and the packing material of the microcapsule structure is mainly prepared from sodium alginate, lactalbumin and soybean proteins. A preparation method of the synbiotic used for feeds comprises the following steps: adding epilactose and the lactic acid bacteria to a packing material solution, and fully and uniformly mixing the epilactose, the lactic acid bacteria and the packing material solution; and carrying out compressed air extrusion to form liquid drops, dropwise adding the liquid drops to a coagulating agent solution, coagulating the mixture to obtain microcapsules, and drying the microcapsules to obtain the synbiotic used for feeds. The synbiotic used for feeds can be added to the feeds in order to promote growth of animals, increase the body weight, promote propagation of intestinal probiotics, guarantee healthy growth of the intestinal tract and improve the body immunity, is safe, has no side effects, and can be used for a long term.

Description

technical field

[0001] The invention belongs to the field of feed additives, and in particular relates to a synbiotic for feed, a preparation method thereof and an application thereof in animal feed for livestock and poultry breeding. Background technique

[0002] The long-term addition of feed antibiotic growth-promoting agents in feed has caused the drug residues in animal-derived food to exceed the standard seriously, posing great harm to the national health and ecological environment of our country, and has become a constraint to the healthy and sustainable development of my country's feed industry. Bottleneck problem. Therefore, it is of great practical significance and long-term development prospect to develop and develop safe, efficient and green alternatives to feed antibiotic growth promoters.

[0003] The concept of synbiotics (Synbiots) was proposed by Gibson and Roberfroid in 1995. It is a mixture of probiotics and prebiotics, which has the ability to increase th...
