7 results about "Feather meal" patented technology

This invention relates to the field of feed science and technology, specifically to a feed preparation method for improving the appearance, oiliness, and color of pig concentrate. The concentrate consists of a main ingredient and auxiliary ingredient system. The main ingredient core includes 100-350 parts of 46% protein dehulled soybean meal, 150-300 parts of high-temperature, high-pressure hydrolyzed feather meal, 15-30 parts of grade IV degummed soybean oil, and 15-40 parts of phospholipid oil powder, etc.; the auxiliary ingredients include fruit and milk flavoring agents that target the olfactory preferences of growing pigs. The process strictly limits the pore size of the bulk plant raw materials to 1.5-2.0 mm and uses lipid emulsification spraying technology to construct a "reflective microemulsion film" on the powder surface. This invention utilizes the optical superposition of the solid golden color of hydrolyzed feather meal and the deep yellow color of grade IV soybean oil to give the product a golden, delicate, and long-lasting glossy appearance. Furthermore, the solution overcomes the palatability bottleneck of high-proportion feather meal replacing conventional protein, effectively improving the daily weight gain of pigs and significantly reducing the rate of hindgut diarrhea.

The application provides a method for promoting degradation of waste feather by feather powder. The method is characterized in that feather powder is added to an inorganic salt culture medium containing waste feather as the only carbon and nitrogen source, and then microorganisms with the function of degrading keratin are inoculated to degrade the waste feather. The method has the advantages of short degradation time of waste feather, significantly improved degradation rate and keratinase activity, low cost and easy operation. The application can accelerate the green transformation and high-value application of waste feather, and can screen and enrich germplasm resources for degrading keratin, thereby helping to realize the green and circular high-quality development of the livestock and poultry breeding industry.

This invention discloses a method for preparing and applying a microbial protease liquid fertilizer, comprising the following steps: S1. Mixing animal and plant protein raw materials with water, and subjecting them to physical-assisted cell wall disruption to obtain a pretreated protein slurry; S2. Inoculating with a composite seed liquid, and performing aerobic fermentation and enzymatic hydrolysis at 45-50℃ for 48-60 hours, maintaining the pH of the fermentation broth at 6.5-7.5 to obtain an enzymatic hydrolysate; S3. Cooling to 28-35℃, inoculating with a mixed probiotic agent, and performing anaerobic or facultative anaerobic fermentation for 48-72 hours to obtain a fermentation broth; S4. Adding trace element salts, and stirring the reaction at 40℃ to 45℃ for 1.5-2.5 hours to allow small molecule active peptides in the fermentation broth to undergo in-situ complexation with metal ions, followed by post-treatment to obtain the microbial protease liquid fertilizer; Through the synergistic effect of physical cell wall disruption and composite enzymatic hydrolysis, the conversion efficiency of recalcitrant waste protein raw materials such as feather meal is significantly improved.
