Yeast additive for feed for improving quality of pork pigs and preparation method of yeast additive

Abstract

The invention discloses a yeast additive for a feed for improving the quality of pork pigs and a preparation method of the yeast additive. The feed additive disclosed by the invention is used in the breeding process of the pork pigs, so that the pork quality can be improved, the daily gain of the pork pigs can be increased, the utilization efficiency of protein, energy and fibers by the pork pigs in a daily ration can be improved, the flavor of the pork can be improved, the added value of the pork can be notably increased, and the economic benefits of pig breeding industry are increased. After the feed additive disclosed by the invention is applied, the weight increment speed of the pork pigs is notably increased, the tenderness of meat quality is notably improved, and the quality and the mass of the pork are greatly increased.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a pig quality-improving feed yeast additive 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 factors in the raw material that are unfavorable to a...

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
