Sperm survival rate improving yeast extract and preparation method thereof

Abstract

The present invention discloses a sperm survival rate improving yeast extract and a preparation method thereof. The sperm survival rate improving yeast extract is composed of the following raw materials in parts by weight: 150-170 parts of discarded saccharomyces cerevisiae, 4-6 parts of activated carclazyte, 3-5 parts of lime milk, 0.01-0.02 part of chitin enzyme, 0.02-0.03 part of protease, 1-2 parts of egg white, 2-3 parts of black bean peptides, 1-2 parts of mactra antiquata meat powder, 0.3-0.8 part of carrageenan, 1-2 parts of dehydrated scallion powder, 1-2 parts of xueyingzi (amaranthaceae, a plant viagra) powder, 0.5-1 part of epimedium brevicornum extract, 0.5-1 part of polygonatum sibiricum extractum, 0.1-0.2 part of lotus flower pollen, 2-3 parts of walnut meat powder, and 0.1 0.2 part of sodium lactate. The yeast extract can promote male livestock sperm production, improve the survival rate of sperms, enhance sperm motility, increase the number of sperms, lower sperm deformity rate and sperm acrosome abnormal rate, improve the physical condition of male livestock, and increases male livestock use life.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a yeast paste for improving sperm survival rate and a preparation method thereof. Background technique [0002] Saccharomyces cerevisiae belongs to the Saccharomycetes family. It is a single-celled organism that is oval or spherical. It reproduces in three ways: budding, spores, and conjugation. It is simple in shape but complex in physiology. It is used in winemaking industry. Saccharomyces cerevisiae is widely used in the brewing industry, and there are many types, among which the use of brewer's yeast is the most common. Brewer's yeast has high nutritional value. It contains about 50% protein, 6-8% nucleic acid and rich in B vitamins, vitamin D, fat, polysaccharides and mineral components. In addition, it also contains a variety of high economic value The coenzymes and physiologically active substances contained in it, such as coenzyme A, coenzyme Ⅰ, cytochrome C, coa...

Problems solved by technology

In the past, due to the limitation of technical level, the waste yeast of Saccharomyces cerevisiae was directly used as animal feed without wall-breaking treatment, and some were used as animal feed after autolysis and some simple processing. The processing level of these processing methods was not high, and obtained The palatability of the product is poor, the quality is not stable, and the utilization rate of yeast protein is also low
