Preparation method for fermented feed for corn-bean pulp type daily ration

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 ...

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 feed that uses full price feed, feed concentrate or energy protein feed as raw materials. Adding lactic acid bacteria and enzyme preparations to prepare fermented complete feed rich in probiotics and polypeptides

This patent does not degrade the anti-nutritional factors for the main raw materials in the full-price feed, and does not significantly improve the digestibility of the feed. At the same time, enzyme preparations such as protease are added when preparing polypeptides, which will increase additional production costs.
