Problems solved by technology

[0003] my country is rich in wheat straw resources, but due to the high fiber and lignin content of wheat straw and low nutrient content, although dairy cows can eat it directly, it has not been widely used in dairy farming; distiller's grains are starchy raw materials that are left over after yeast fermentation. The waste that comes down, which contains crude protein, crude fat, crude fiber and nitrogen-free extracts, is a good nutritional substrate for microorganisms, but when it is directly fed as animal feed, it has problems of poor digestibility and palatability. In the feed industry small amount added

Embodiment 1

[0023] A new process for producing dairy cow fermented feed using wheat straw and distiller's grains as raw materials. The specific preparation steps are as follows:

[0024] (1) Degradation of wheat straw: crush wheat straw to 60 mesh, adjust the water content to 30% to 40%, add quicklime with a mass ratio of 4% to 6% of wheat straw, stir evenly, and keep it in a wet state for 72 to 96 hours;

[0025] (2) Preparation of solid medium: add water to the medium components according to the ratio of 40% of wheat straw degradation products, 30% of distiller's grains, 10% of corn steep liquor, 4% of bran, 10% of bean cake powder, 3% of urea, and 3% of ammonium sulfate Mix evenly, control the water content at about 65%, sterilize at 121°C for 20 minutes, and cool to room temperature;

[0026] (3) Aspergillus activation: take fresh bran, sieve fine powder with a 60-mesh sieve, add water according to the ratio of bran: water = 1: 1.0-1.3, mix well until there is no dry powder and no ag...

Abstract

The invention discloses a fermented feed for dairy cows, which is prepared from raw materials of wheat straw and distillers' grains, is produced by using microbial fermentation and is high in content of proteins, strong in palatability and rich in saccharomyces cerevisiae, bacillus subtilis and other probiotics. In the product, the content of true proteins is about 42-48%, the content of the proteins is improved by above 12%, and the fermented feed further contains a large number of beneficial live bacteria, a variety of vitamins, enzymes, amino acids, short peptides, high-quality proteins and other nutritional ingredients. The fermented feed disclosed by the invention has the advantages that 1) through the fermentation enzymolysis effect of microbes, the content of the true proteins in the product is improved, thereby being conductive to making up for the blank in the protein feed for farming the dairy cows in China; 2) the product is rich in the nutritional ingredients and has the advantages of promoting growth and development of the dairy cows, increasing the utilization rate of the feed, enhancing the immunity, improving intestinal microecology, preventing diseases, reducing environmental pollution, increasing the milk production rate and the like; and 3) the solid-state fermentation is adopted, so that the production process is simple and environmental pollution is avoided.

Description

technical field [0001] The invention relates to a new process for producing dairy cow fermented feed by using wheat straw and distiller's grains as raw materials, belonging to the field of feed processing. Background technique [0002] Protein raw materials are the foundation of the development of feed industry. The shortage and high price of protein raw materials in my country have become one of the bottlenecks restricting the development of animal husbandry. At present, with the improvement of people's living standards and the emphasis on the quality of life, the demand for meat, eggs, milk, and aquatic products is increasing day by day. The production of grain and feed is facing severe challenges, and feed protein resources will become increasingly scarce. It is imminent to expand feed resources and develop unconventional feed. The important strategy to alleviate the contradiction is to improve the utilization rate of the existing protein source, tap the available nutrit...
