Preparation technology and application of environment-friendly comprehensive deodorization biological feed for fattening pigs

Abstract

The invention provides a compound fermentation biological feed and a preparation method thereof. The method comprises the steps of fermentation of base material components, a fermentation process and the like. The compound fermented biological feed is prepared from the following raw materials in parts by weight: 65 to 72 percent of corn, 5 to 12 percent of soybean meal, 9 to 12 percent of rice bran meal, 7 to 10 percent of bran, 1.0 to 1.5 percent of mountain flour, 0 to 0.2 percent of calcium hydrophosphate, 0.5 to 0.9 percent of lysine, 0 to 0.1 percent of methionine, 0.1 to 0.2 percent of threonine, 0 to 0.1 percent of tryptophan, 0.2 to 0.5 percent of table salt, 0 to 0.05 percent of phytase, 0.01 to 0.03 percent of multi-vitamin and 0.2 to 0.3 percent of multi-mineral. The six fermentation strains, namely lactobacillus rhamnosus, lactobacillus plantarum, bacillus licheniformis, bacillus subtilis, saccharomyces cerevisiae and candida utilis, are adopted. According to the present invention, the high-quality biological fermentation feed is produced by using the conventional complete feed, the nutrition is balanced, the palatability is good, the concentration of ammonia gas and hydrogen sulfide in the manure odor of the fattening pigs can be significantly reduced by more than 60%, and the air environment of the pig house is improved; meanwhile, the feed conversion ratio can be reduced by 14.5%, the production performance is effectively improved, and the feed cost is remarkably reduced.

Description

Technical field[0001]The present invention relates to a composite fermentation bio feed and a preparation method thereof, belonging to the field of biotechnology.Background technique[0002]my country has currently become a world of live pigs. According to the National Bureau of Statistics, my country's piglet column is about 700 million in 2014. In 2019, the whole year of African pigs fell 21.6% in the previous year, but also reached 544 million. At the same time, pig breeding brings huge economic benefits and social benefits, it has also highlighted the shortage of protein feed resources in my country and the problem of severe pig manure pollution. In many environmental pollution caused by pig manure, odor pollution is an important aspect in the contamination of livestock and pouternity. The constituents of malodous materials are complex, with a strong toxicity, such as ammonia and hydrogen sulfide concentration to make human livestock. As one of the environmental public hazards, ma...
