Preparation method of rapeseed meal fermented feed

Abstract

The invention provides a preparation method of a rapeseed meal fermented feed. The preparation method is characterized by comprising the following steps of: adding rapeseed meal to molasses and calcium carbonate, and taking the obtained mixture as a fermentation raw material; inoculating saccharomyces cerevisiae and saccharomyces boulardii for solid-state fermentation; and drying and crushing the obtained fermentation product so as to finally obtain the rapeseed meal fermented feed. The preparation method has the beneficial effects that solid-state fermentation of the rapeseed meal is carried out by the saccharomyces cerevisiae and the saccharomyces boulardii, which can degrade anti-nutritional factors in the rapeseed meal, improve the content of crude protein and soluble protein, generate a certain amount of organic acid and obtain special flavor so as to improve the digestive absorption capability of animals and the utilization ratio of the feed and effectively enhance the production performance of animals; and protein energy is supplemented, the immunity of animals is improved, in-vivo micro-ecological balance is regulated, pathogenic bacteria growth is inhibited, disease prevention and resistance capabilities are strengthened, and the problems such as dyspepsia, diarrhea, poisoning, poor disease resistance of organisms and the like can be well solved when the rapeseed meal feed is used for raising livestock.

Description

technical field [0001] The invention relates to a preparation method of rapeseed meal fermented feed. Background technique [0002] Rapeseed is one of the most important oil crops in my country. In 2004, the planting area of ​​rapeseed in the country reached 7.33 million mu, with an annual output of 12.8 million tons of rapeseed, accounting for about 30% of the world's total and ranking first in the world. Rapeseed meal has the same nutritional content as soybean meal. When rapeseed meal and soybean meal are used together, they can play a good role in the balance of amino acids and complement each other. Compared with rapeseed meal alone, it can improve the growth performance of animals. [0003] Rapeseed meal contains toxic or anti-nutritional substances such as glucosinolates (glucosinolates), phytic acid, and tannic acid, which can cause animal poisoning and have extremely poor palatability. Therefore, if rapeseed meal is to be put into feed, it must be detoxified. The ...
