Problems solved by technology

However, the shortage of feed resources in our country seriously restricts the development of the pig industry.
At the same time, the utilization of unconventional feed materials is obviously insufficient, and they are usually discarded as waste or simply used as fertilizers, resulting in waste of resources and environmental pollution.

Abstract

The invention discloses fermented feed for growing and fattening pigs. The fermented feed takes corn flour, bean meal, DDGS, wheat bran, stevia residues and large leaf medlar powder as raw auxiliary materials, reagents of urea, ammonium sulfate, calcium hydrogen phosphate and magnesium sulfate are added on the basis of the raw auxiliary materials, and mixing is conducted to obtain a fermentation substrate; bacillus subtilis liquid, candida liquid, aspergillus niger liquid and lactic acid bacterium liquid are mixed to combined fermentation strain liquid; after the fermentation substrate and thecombined fermentation strain liquid are evenly mixed, fermentation is conducted, and a finished product is dried; and trace elements, vitamins and amino acid are added, and a finished feed product isobtained after thorough mixing. According to the fermented feed, the content of proteins of the feed can be increased, the content of crude fibers is decreased, the palatability of animals to the feed is improved, the nutrient digestion utilization rate is increased, and the nutritive value of the feed is improved comprehensively.

Description

technical field [0001] The invention relates to a fermented feed for fattening pigs, belonging to the technical field of feed. Background technique [0002] my country's pig production accounts for half of the world. However, the shortage of feed resources in my country seriously restricts the development of the pig industry. At the same time, the use of unconventional feed materials is obviously insufficient, and they are usually discarded as waste or simply used as fertilizers, resulting in waste of resources and environmental pollution. Treatment of unconventional feed materials through biotechnology, especially microbial fermentation technology, can improve nutritional value and is a safe and efficient method for the development of low-quality feed resources. Contents of the invention [0003] The purpose of the present invention is to provide a fermented feed for fattening pigs, which can increase the amount of true protein in the fermentation substrate, reduce the ...
