Abstract

The invention relates to a method for preparing dairy cow feed by microbial fermentation, which comprises the following steps of: performing primary culturing on yeast and aspergillus niger, mixing, and performing secondary culturing; fermenting a feed substrate according to a specific ratio, wherein the substrate is prepared by mixing 1 to 3 weight parts of bean pulp, 8 to 10 weight parts of cotton dregs, 6 to 15 weight parts of alcohol meal, 7.5 to 15 weight parts of maize, 25 to 35 weight parts of maize fiber feed, 4 to 8 weight parts of maize peel, 15 to 22 weight parts of bran and 6 to 10 weight parts of ammonium sulfate; and after fermenting, drying and crushing to obtain a feed finished product. The invention also provides dairy cow feed prepared according to the method, which has high crude protein content.

Description

technical field [0001] The invention relates to a method for preparing dairy cow feed by microbial fermentation, in particular to a method for preparing dairy cow feed by selecting high-quality yeast and Aspergillus niger strains and adopting scientific fermentation technology, and the dairy cow feed prepared according to the method . Background technique [0002] In recent years, the dairy farming industry has achieved rapid development in my country. The number of dairy cows in my country increased from 4.265 million in 1998 to 10.63 million in 2004, an average annual increase of 16.4%. However, the overall production level of dairy cows is still relatively low, and the average annual milk production of dairy cows does not exceed 5,000 kilograms, which is far from developed countries. At the same time, the disease control and prevention system of dairy cows is not perfect, resulting in a high incidence of nutritional metabolic diseases and obstetrical diseases of dairy c...
