Piglet protein feed and production method thereof

Abstract

The invention relates to a piglet protein feed and a production method thereof, which belong to the technical field of herding feed processing technology. In a method for removing anti-nutritional factors of soybean or soybean residue, hot-press puffing is adopted firstly, and then aerobic fermentation and anaerobic fermentation are carried out. The method can remove the anti-nutritional factors in low-temperature desolventized soybean residue and raw soybean, overcomes the serious defect that the anti-nutritional factors are used as the main protein nutrition sources for the piglets, and promotes the production of a large number of easily digestible functional nutrients and flavor components. The soybean residue material fermented grains and soybean meal material fermented grains of the obtained anti-nutritional factors are the piglet protein feed with good quality, and are used for preparing full-price daily ration for piglets with the ages of 7-70 days, the adding proportion is 15-30%, the feed replacing the soybean residue increases the daily gain by 10.5%, reduces the diarrhea rate by 30%, and increases the survival rate by 8%; and the feed replacing imported fish meal, proteinic powder of porcine corpuscle and other animal-based protein feeds reduces the daily ration cost by 15-30% and increases the biological safety of the feed.

Description

technical field [0001] The invention relates to the field of livestock feed, especially a high-quality protein feed for piglets and its production technology. Specifically, the invention relates to a combination of hot-pressed puffing processing technology and microbial solid-state fermentation technology for degrading soybeans and soybean meal. Anti-nutritional factors, so as to improve the nutritional value and digestibility of low-temperature desolvated soybean meal and raw soybean, a special high-quality protein feed production technology for piglets. Improve piglet health and performance and reduce feed costs. It is a biological feed processing technology that combines physical processing and biological treatment to rapidly increase the biological potency of raw soybeans and low-temperature desolvated soybean meal. Background technique [0002] The pig industry is the main industry that provides high-quality animal protein sources for human food. Piglet feeding is the ...

AI Technical Summary

Problems solved by technology

[0002] The pig industry is the main industry that provides high-quality animal protein sources for human food. Piglet feeding is the key and difficult point in pig production. The common problems are high diarrhea rate, low survival rate and low growth rate in piglets

In the existing research in this field, the problem encountered by thermal processing is that the effect on non-heat-sensitive anti-nutritional factors is not ideal, the effect is simple, and the specific parameters have not been determined

The extruded soybean meal on the market only adds the high-temperature extrusion process of soybeans in the oil production process, which is very limited in the removal of anti-nutritional factors; the research on microbial fermentation processes is mostly concentrated in the laboratory level and the field of liquid fermentation, and the on-site production technology There are still many problems that have not been effectively solved, such as the efficient combination of fermentation strains, the conversion of aerobic fermentation and anaerobic fermentation time, the improvement of fermentation speed, effective product testing indicators and methods, etc.
