Yeast culture preparations for ruminant animal husbandry and methods for preparing yeast culture preparations for ruminant animal husbandry.

Abstract

The invention proposes a yeast culture preparation for ruminant animal husbandry, a method for the preparation and application of the yeast culture preparation for ruminant animal husbandry. The method includes: mixing and fermenting fermentable raw materials, yeast additives, bacterial fermentation agents, and synthetic enzyme agents, to obtain a yeast culture preparation; yeast additives include yeast hydrolysates, yeast metabolites or yeast cell membranes; bacterial fermentation agents include one or more yeasts, lactic acid bacteria or spore-forming bacteria; fermentable raw materials include fermentable carbon sources and fermentable nitrogen sources; fermentable carbon sources include corn flour and bran; and fermentable nitrogen sources include soybean meal, mixed flour and dry cereal residues containing solubles (DDGS).This method can solve the problem of yeast culture preparations used in ruminant animal husbandry, where previous techniques could not simultaneously meet the nutritional needs of the animals and maximize the effects of yeast, and is suitable for the ruminant animal husbandry field.
