Fermented feed and production process thereof

Abstract

The invention provides a fermented feed and a production process thereof, wherein the fermented feed forms composite fermentation strains by three groups of lactic acid bacteria, yeast and bacillus which have more than ten bacterial strains, the composite fermentation strains are mixed with molasses according to the ratio of 1:1 and are mixed with fermentation zymolyte (cottonseed meal is mixed with rapeseed meal with the grain size of 1.0 to 2.0mm according to the ratio of 90:10-60:40) to form fermentation material according to the ratio of 0.1 percent, after the moisture content of the material is adjusted to 40-60 percent, fermentation of 30 plus or minus 2 DEG C is carried out for 48 hours, and expansion drying under 80 DEG C is carried out after completing the fermentation. Compared with non fermentation, a fermentation miscellaneous meal product produced by the production process reduces the gossypol, isothiocyanate and oxazolidinethione contents by more than 80 percent, improves the crude protein content by more than 5 percent, and has the lactate content larger than 2.5 percent and pH value about 4.5. The product can substitute soya bean meal of 30 to 50 percent in small, medium and large pig feed, the feed cost is lowered by 20 to 50 yuan/ton, feed intake is improved by about 10 percent, the feed meal has close phase comparison, daily gain is improved by about 4 percent, the morbidity is greatly reduced, and the ammonia odour of a colony house is obviously reduced.

Description

Technical field [0001] The invention relates to a fermented feed and a production process thereof. Specifically, more than ten bacterial strains from three groups of lactic acid bacteria, saccharomyces, and Bacillus are used as composite fermentation strains, and the feed raw materials (miscellaneous meal, such as cotton meal, rapeseed meal, etc.) , peanut meal, etc.) into a bio-fermented feed material containing microbial cell protein, bioactive small peptide amino acids, microbial active probiotics, compound enzyme preparations, and small molecule proteins. It belongs to the field of biotechnology. Background technique [0002] With the rapid development of animal husbandry, the contradiction between human and animal food is becoming more and more prominent. To solve this problem, the scientific and technological circles and industrial circles all over the world are looking for and researching new feed resources, and fermented feed is getting more and more attention. Ferm...

Problems solved by technology

However, the cost of soybean meal is high, and fermented soybean meal can only be used as a high-grade protein raw material in high-priced feed such as suckling pig feed, sow feed, and high-grade fish and shrimp feed.

Miscellaneous meal, such as cotton meal, rapeseed meal, peanut meal, etc., has large output, large quantity and low price in my country, but miscellaneous meal contains more anti-nutritional factors, and its palatability is not good, and the animal digestibility is not high, so Can not be added in large quantities in the feed
