Yeast additive for growth and development promoting and body immunity enhancing feed of piglets and preparation method thereof

Abstract

The present invention discloses a yeast additive for a growth and development promoting and body immunity enhancing feed of piglets and a preparation method thereof. The feed additive is rich in various nutrients needed for the growth of piglets, can effectively assist the piglets to digest and absorb the feed, improves the feed utilization rates, is free of hormones and chemical residues, and can also enhance the body constitution of the piglets, improve body immunity, and reduce the incidence of the diseases while promoting the growth of the piglets.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a feed yeast additive for promoting growth and development of piglets and enhancing body immunity and a preparation method thereof. Background technique [0002] During the rapid development of animal husbandry, its demand for food, especially protein feed, is increasing. Every year, my country imports a large amount of raw materials such as fishmeal and soybeans to make up for the shortage of domestic raw materials. Therefore, it is urgent to develop and utilize new feed resources. Chinese scientific researchers have explored this in many aspects, and microbial fermented feed has attracted much attention. Microbial fermented feed refers to the use of plant-based agricultural and sideline products as the main raw material under artificial controllable conditions (such as temperature, moisture, time, etc.), through microbial fermentation, to decompose the anti-nutritional...

The article "Production Technology of Feed Grade Yeast Single-cell Protein" introduces a method of producing a feed-grade yeast single-cell protein additive through yeast fermentation. The raw materials used in this method are mainly corn soaking water and corn dregs and other waste water produced by corn deep processing plants. and waste residue, because this method does not provide the specific process steps and control conditions of the production process, and also lacks further research on feed yeast additives. In addition, its production methods are relatively traditional and conservative, and the deep processing and functional improvement of feed yeast Therefore, the quality of feed products obtained by them is not high, the functionality is not strong, it is difficult to meet the higher requirements of the new social development for feed products, it is difficult to gain a foothold in the market competition, and it is easy to lead to elimination and elimination
