Problems solved by technology

The patent uses two mixed strains of Lactococcus and Saccharomyces cerevisiae for fermentation, and protease is added in the production process, which increases the production cost. In addition, the product obtained by this patent lacks the beneficial effect of promoting the balance of intestinal flora and preventing digestive tract diseases Live bacteria, and only a single protein feed, also needs to be used in conjunction with energy feed; Chinese invention patent application No. 200710024276.3 discloses a kind of fee

Embodiment 1

[0020] Use corn, soybean meal and bran (6:2:2, w / w / w) as raw materials, mix them with water at a material-to-water ratio of 1:0.6 and stir evenly, then sterilize at a temperature of 105°C After sterilization, add 40wt% lactic acid bacteria casei, 0wt% saccharomyces cerevisiae and 0wt% bacillus subtilis according to the weight of the raw materials, stir evenly, and ferment at 35°C; the fermentation time is 48 hours; low-temperature drying is carried out after the fermentation is completed. The degradation rate of soybean antigen protein in the fermented feed reached 40%, the degradation rate of raffinose and stachyose that caused flatulence reached 0%, the peptide content reached 2.8%, the lactic acid content reached 4.2%, and the digestible energy value increased from 13.2MJ / kg to 13.3 MJ / kg, the number of beneficial viable bacteria reaches 10 7 CFU / g or more.

Embodiment 2

[0022] Use corn, soybean meal and bran (6:2:2, w / w / w) as raw materials, mix with water at a material-to-water ratio of 1:0.8 and stir evenly, then sterilize at a temperature of 105°C After sterilization, insert 20wt% lactic acid bacteria casei, 0wt% saccharomyces cerevisiae and 20wt% bacillus subtilis according to the weight of the raw materials, stir evenly, and ferment at 35°C; the fermentation time is 48 hours; low-temperature drying is carried out after the fermentation is completed. The degradation rate of soybean antigen protein in the fermented feed reaches 92%, the degradation rate of raffinose and stachyose that cause flatulence reaches 20%, the peptide content reaches 7.8%, the lactic acid content reaches 3.8%, and the digestible energy value increases from 13.2MJ / kg to 13.5 MJ / kg, the number of beneficial viable bacteria reaches 10 8 CFU / g or more.

Embodiment 3

[0024] Use corn, soybean meal and bran (6:2:2, w / w / w) as raw materials, mix them with water at a material-to-water ratio of 1:1.0 and stir evenly, then sterilize at a temperature of 105°C After sterilization, add 20wt% lactic acid bacteria casei, 4wt% saccharomyces cerevisiae and 8wt% bacillus subtilis according to the weight of the raw materials, stir evenly, and ferment at 35°C; the fermentation time is 48 hours; low-temperature drying is carried out after the fermentation is completed. The degradation rate of soybean antigen protein in the fermented feed reaches 82%, the degradation rate of raffinose and stachyose that cause flatulence reaches 92.8%, the peptide content reaches 6.4%, the lactic acid content reaches 3.2%, and the digestible energy value increases from 13.2MJ / kg to 13.8 MJ / kg, the number of beneficial viable bacteria reaches 10 8 CFU / g or more.

Abstract

The invention discloses a preparation method for a fermented feed for corn-bean pulp type daily ration, taking corn, bean pulps and bran (6:2:2, w/w/w) as raw materials and is applied to microbial fermentation engineering. The degradation rate of soybean antigen protein in the fermented feed reaches at least 80 percent, the degradation rate of raffinose and stachyose which cause flatulence reaches at least 90 percent, the peptide content is improved by at least 2 times and reaches at least 6 percent, the lactic acid content reaches at least 3 percent, the digestible energy value is increased to 13.8MJ/kg from 13.2MJ/kg, and the number of beneficial viable bacteria reaches at least 108CFY/g. The prepared novel fermented feed can be singly or proportionally mixed (about 40 percent) with thecorn, the bean pulps and the bran, and added with substances like vitamin, inorganic salt and the like to form a complete feed for growing and fattening pigs, for animals to eat. The feed can effectively improve the digestive absorption capacity of the animals, regulate the microcological equilibrium in animal bodies, enhance the disease prevention and control capacity of the animals and improve the growth performance of the animals.

Description

technical field [0001] The invention relates to a method for preparing a corn-soybean meal type ration feed, in particular to a method for preparing a fermented complete feed with low antigen, high peptide and high lactic acid, belonging to the field of animal feed. Background technique [0002] Feed is the material basis of animal husbandry and is very important to animal husbandry production. The scale and development speed of animal husbandry production mainly depend on the amount of available feed. The quality of feed has a major impact on the quality of animal products. Its quality directly Affect the economic benefits of animal husbandry production. Livestock products are essentially feed conversion products, and high-quality, nutritious feed is a necessary condition to ensure the quality of livestock products. However, toxins and pathogenic microorganisms in feed often remain in animal products, affecting the quality of animal products. Therefore, to develop animal ...
