Problems solved by technology

But this technology has the following defects: it can only be limited to the treatment of agricultural waste or grain and oil processing waste; the content of water-soluble nutrients transformed into is not high (only 30-70%); The crude protein content is not high, and none of the five enzymes used in this technology, such as protease, has the effect of converting or synthesizing protein, so it is impossible to achieve "increasing crude protein from 1-3% to 10-60%" and the effect of "converting non-protein nitrogen in the raw material to protein nitrogen"

Embodiment 1

[0010] Embodiment 1 Production of piglet (early stage) compound feed

[0011] Corn 591kg, secondary flour 95kg, soybean meal 235kg, fish meal 50kg, pulverized (more than 85% of the particle size is less than 1.4mm), add 1000kg of clean water, stir, adjust PH6.0-6.3 with 10N hydrochloric acid, add α-bacterial amylase (dosage : 5 units / gram of feed), stir evenly, gradually heat up to 90°C, keep warm at 86-89°C for about 20-30 minutes, and stir continuously until the solution does not develop color when it encounters iodine, then heat up to 100°C to inactivate the enzyme 5-10 minutes. Then cool down to 65°C with water cooling, add glucoamylase (100 units / gram feed), lipase (20 units / gram feed), cellulase, hemicellulase (consumption is respectively 15 units / gram feed), and use 10N hydrochloric acid Adjust the pH to 4.5, maintain the temperature at 58-61°C, and hydrolyze for 4 hours. Then cool it down to 55°C with water, adjust the pH to 6.5 with 10N sodium hydroxide, add 3.942 (...

Embodiment 2

[0014] Example 2 Production of concentrated feed for growing and fattening pigs with a body weight of 15-30 kg (concentrated feed consumption 30%)

[0015] Weigh 274kg of soybean meal and pulverize it to 60-80 mesh, add 300kg of clean drinking water, adjust the pH to 6.5 with 10N hydrochloric acid, add fungal protease (Aspergillus soil 3.942), dosage: 1000 units per gram of feed. Heat up, hydrolyze at 50-55°C for 4-6 hours, stir for a few minutes every half hour, and check with ninhydrin reagent. 90°C, use feed grade calcium carbonate to adjust the pH value to 6.0-6.3, add α-amylase (8 units / g feed), hydrolyze at 61-65°C until the filtrate does not develop color when it meets iodine, stop hydrolysis (At this time, there are no macromolecular substances such as starch and protein in the hydrolyzate, but there are substances such as small molecule dextrin, maltose, glucose, peptide and amino acid). Add 12kg of calcium hydrogen phosphate, 4kg of salt, and 10kg of compound premix...

Abstract

A process for preparing the feed for animal by zymohydrolysis features that the basic high-energy material and / or basic protein material are zymohydrolyzed to degradate the macromolecular starch, cellulose and coarse protein into micromolecular monoose, biose, amino acids, dextrin and peptide. It can increase appetite of animal by 10-25%, growth speed by 12-25% and utilization rate of feed by 10-25%, and decreasing cost by 2-3%.

Description

1. Technical field [0001] The invention belongs to animal feed, in particular to a method for enzymatically hydrolyzing and processing animal feed. 2. Background technology [0002] At present, more than 95% of animal feed is still based on grains and by-products such as corn, wheat, and bran, and animal and plant waste such as fish meal, meat and bone meal, feather meal, blood meal, and cake; the former is rich in starch and fiber. Elements, etc., are referred to as energy base materials (hereinafter the same), and the latter is rich in crude protein and fat, referred to as protein base materials (hereinafter the same). The existing concentrated feeds and compound feeds on the market are all produced with energy-based materials and protein-based materials as the main raw materials, and most of the starch, crude fiber, crude fat and crude protein contained in them still exist in the state of macromolecules. More than 90% of molecular nutrients are insoluble in water, and th...
