Post-sprayed micro-ecological preparation for expanded feeds, and preparation method and application of preparation

Abstract

The invention discloses a post-sprayed micro-ecological preparation for expanded feeds, and a preparation method and application of the preparation. The post-sprayed micro-ecological preparation comprises the following components in percentage by mass: 40 to 60 percent of grease, 1 to 2 percent of solid micro-ecological preparation, 2 to 3 percent of emulsifying agent, 1.5 to 3 percent of protective agent, 0.1 to 0.3 percent of preservative and the balance of water. The preparation method comprises the following steps of dissolving the solid micro-ecological preparation into water, simultaneously adding the protective agent and the preservative, and uniformly stirring the components to obtain a liquid micro-ecological preparation; uniformly mixing the grease and the emulsifying agent while stirring, adding the liquid micro-ecological preparation, and performing homogenizing to completely and uniformly mix the components to obtain the post-sprayed micro-ecological preparation for the expanded feeds. The post-sprayed micro-ecological preparation can be directly sprayed onto the surfaces of the expanded feeds, can be stored for a long time, and is high in viable bacterium content and stable in activity, the shortcomings of high death rate of viable bacteria and high activity loss of a conventional liquid micro-ecological preparation are avoided, feed production procedures are simultaneously simplified, the feed production cost is lowered, and the quality of the feeds is improved.

Description

technical field [0001] The invention belongs to the field of feed micro-ecological preparations and applications thereof, in particular to a post-spraying micro-ecological preparation of extruded feed, a preparation method and application thereof. Background technique [0002] Probiotics are safe, non-toxic and side effects, no residue, no pollution, no drug resistance, low cost, easy to use, and can promote animal growth, prevent human and animal diseases, and replace antibiotics. Feed microecological preparations are based on the safety issues of feed antibiotics. It can not only inhibit pathogenic bacteria, be non-toxic to livestock products and promote the growth of livestock and poultry, but also improve the meat quality and flavor of livestock products, which is beneficial to Ecological environment and export trade are the best solutions for future green feed. [0003] At present, the pre-addition of probiotics during feed processing is likely to lead to the inactivat...

AI Technical Summary

Problems solved by technology

However, this spraying technology is for ordinary liquid probiotics, because the probiotics need to be sprayed on the surface of the extruded pellet feed, so the surface temperature of the feed and the subsequent packaging and transportation process are likely to cause bacterial inactivation , affecting the feeding nutritional value of the feed itself
