Preparation of forage protein by enzymolysis technology: After using the enzymolysis technology to remove the most of phytic acid, polyphenols, glucosides and other substances from the double-lower shelled rapeseed meal obtained from the pre-extraction and leaching processes in China, It can be used as the main source of crude protein in compound feed for poultry, livestock and fish. Studies have shown that the advantages of enzymatic treatment are: simple equipment, easy-to-use enzymatic hydrolysis technology, low investment, and quick results. The annual enzymolysis equipment for processing 10,000 tons of bread cake is only about 500,000 yuan, and the construction period is only about 2 months. It is suitable for technological transformation of existing feed factories, and the elimination of harmful substances glucosinolates and anti-nutrients is effective. After enzymolysis, the elimination rate of harmful substances and anti-nutrients in shelled pancakes reached more than 80%, and the use of this pancake for compound feed was effective. Research trials have shown that the feeding carp is 2.2 times faster than conventional feeding, its breeding cycle is about 45 days shorter than conventional feed, the feed coefficient is 1.81, formula cost is more than double that of commonly used formulas, and 75% of soybean cake is replaced Breeding pigs is growing faster than conventional feeds, but there is no damage to pigs. The price of soybean meal is nearly twice as high as that of rapeseed meal. This alone can greatly reduce the cost of feeding. The study of its mechanism shows that due to the elimination of anti-nutritional phytic acid and polyphenols, the protein's biological titer is increased, and trace elements can be effectively absorbed and utilized.
