Problems solved by technology

[0002] Cottonseed meal is a flour cake obtained after cottonseed is pressed, and then most of the residual oil is separated through the leaching process to obtain a reddish or yellow granular product, which is the main raw material for making feed. There is a large amount of free gossypol in cottonseed cake and cotton meal, and free gossypol is harmful to animals. Therefore, when taking cotton meal directly, it may cause animal poisoning or reduce the sperm motility of male animals, and there is also a high amount of free gossypol in cotton meal The crude protein will reduce the utilization of gossypol in the feed due to gossypol when feeding animals, which needs to decompose the gossypol in the gossypol, and the current traditional method of decomposing gossypol has the following disadvantages: High crude fiber content, poor applicability, cannot be used in feed
Low protein solubility and poor utilization
High gossypol content can easily cause animal poisoning and reduce breeding benefits
The appearance color is poor and cannot be used in large quantities
Low digestion and utilization rate, unable to reduce feeding cost

Abstract

The invention discloses a method for fermenting and decomposing gossypol in cottonseed meal by composite strains. Corynebacterium, Torula utilis Henneb, Bacillus subtilis and lactic acid bacteria are used for fermenting and culturing to prepare composite strain fermentation broth; then, the composite strain fermentation broth and a cottonseed meal raw material composed of cottonseed meal, corn steep liquor, molasses, ammonium sulphate, urea and a 10% sodium hydroxide aqueous solution raw material are evenly mixed; and then a solid is fermented, dried, smashed and packaged by a sealed bag to finish decomposing the gossypol in the cottonseed meal. The protein solubility of the fermented cottonseed meal is improved by above 50%, the feed cost is lowered, the breeding benefit is increased, and the cottonseed meal has a wide use range.
