A kind of antibiotic-free microbial fermented feed and preparation method thereof

Abstract

The invention discloses an antibiotic-free microbial fermented feed and a preparation method thereof. The feed is mainly prepared from the following raw materials in parts by weight: 300-800 parts of corn, 45-75 parts of DDGS (Distillers Dried Grains), 8-30 parts of molasses, 120-300 parts of wheat middling, 50-180 parts of bran, 80-200 parts of bean pulp, 2-6 parts of mountain flour, 5-9 parts of calcium hydrogen phosphate, 2-5 parts of table salt, 0.7-1.2 parts of choline chloride, 3-7 parts of anhydrous sodium sulphate, 4-8 parts of 65% lysine, 1-3 parts of 98% threonine, 0.2-0.4 parts of decavitamin, 3-7 parts of polymineral and 2-5 parts of probiotics, the antibiotic-free microbial fermented feed is prepared from fermentation treatment, a novel antibiotic-free fermented feed is researched and produced according to different living habits and biological requirements at different growing periods of pork pigs, and under optimized control conditions, no antibiotic is added, antinutritional factors in plant, animal and mineral substances are decomposed and synthesized by microbial metabolism so as to produce a healthy nutritional feed which is better for ingestion, digestion and nutrient absorption of the pork pigs and is free of toxic effect.

Description

technical field [0001] The invention relates to animal feed preparation technology, in particular to an antibiotic-free microbial fermented feed and a preparation method thereof. Background technique [0002] There are many kinds of common feeds for pigs, which are divided into protein feeds, energy feeds, roughage feeds, green feeds, silage feeds and mineral feeds according to nutrition. Although each type of feed has its own unique functions, there are also requirements for different types of pigs. Pay attention, especially the anti-nutritional factors in plant, animal and mineral substances are not conducive to the digestion and absorption of pigs, and in the production of pigs, the excessive use of antibiotics and the abuse of prohibited drugs due to the eagerness for quick success, and the harmful substances in animal foods Residue or exceeding the standard will seriously affect the quality of pork products, thereby affecting people's health. Therefore, preparing a feed...

[0002] There are many kinds of common feeds for pigs, which are divided into protein feeds, energy feeds, roughage feeds, green feeds, silage feeds and mineral feeds according to nutrition. Although each type of feed has its own unique functions, there are also requirements for different types of pigs. Pay attention, especially the anti-nutritional factors in plant, animal and mineral substances are not conducive to the digestion and absorption of pigs, and in the production of pigs, the excessive use of antibiotics and abuse of prohibited drugs due to the eagerness for quick success, and harmful substances in animal foods Residue or exceeding the standard will seriously affect the quality of pork products, thereby affecting people's health. Therefore, preparing a feed that meets the nutritional needs of pigs and improves the digestion and absorption rate of nutrients without antibiotics can reduce costs and improve utilization. social development needs
