Problems solved by technology

[0004] Since 2012, Chengde Boya Agriculture and Animal Husbandry Development Co., Ltd. has started research in this area, and achieved certain results in early 2013. The utilization efficiency of straw reached about 50% (with the goal of growing and finishing pigs), but enzymatic hydrolysis The production cost of fermentation is high, and the processing cost per ton of straw, only the enzymatic fermentation part exceeds 600 yuan

Embodiment 1

[0032] Step 1: Crush the stalks, the length of which should not exceed 5mm.

[0033] The second step: add wheat bran accounting for about 5% of the weight of the straw to the straw powder.

[0034] Step 3: Add 0.02% xylanase (50,000 IU / g) and 0.01% cellulase (20,000 IU / g) to the mixture of straw and wheat bran.

[0035] Step 4: adding clear water to the mixture with the enzyme added, injecting clear water into the mixture according to 80% of the straw weight, and fully mixing.

[0036] Step 5: Inoculate the lactic acid bacteria liquid and yeast liquid into the mixture that has been injected with clean water. The inoculation proportion of the lactic acid bacteria liquid accounts for about 2% of the straw weight; the inoculation proportion of the yeast liquid accounts for about 0.5% of the straw weight.

[0037] Step 6: Pack the mixed and inoculated materials into packaging bags with additional breathing balance valves, seal them tightly, and stack them in a warehouse with an ...

Embodiment 2

[0042]Select binary hybrid pigs (long × large) of about 40kg, and divide them into 2 treatments according to random block design, each treatment has 6 repetitions (columns), and each repetition has 6 pigs. A total of 12 pens were used in the experiment. The test is divided into two stages: 40-60kg and 60-90kg body weight stage feeding. The experimental group was fed a compound diet containing fermented straw, and the control group was fed a conventional diet containing antibiotics. The test results showed that there was no significant difference in average daily gain, daily feed intake and feed / weight gain ratio between the experimental group and the control group in the first stage (P>0.05). The average daily gain increased by 3.1%; the average daily gain, daily feed intake and feed / weight gain ratio of the second stage between the test group and the control group did not show significant differences (P>0.05). The average daily gain of the enzymatically hydrolyzed and ferme...

Abstract

The invention provides a preparation method of biological feed. The method comprises the following steps of crushing stalks; mixing crushed stalks with wheat bran; adding xylanase and cellulase; then, supplanting and adding water accounting for 75 to 85 percent of the weight of the stalks; then, inoculating lactobacillus liquid and yeast liquid; obtaining the biological feed after the enzymolysis and fermentation. Through the optimized enzymolysis combination, the microbial combination anaerobic fermentation is combined; the water content is reduced to a proper degree, so that the treatment cost of per ton of stalks is reduced by about 300 Yuan; the practical application values are basically realized. The prepared biological feed uses the weight ratio of 20 percent for replacing the complete formula feed; the growth speed, differences of the feed conversion ratio and the like of live pigs are not obvious, but the grain consumption and the live pig weight increase cost are obviously reduced; the contents of pork protein, amino acid and calcium can be increased; the contents of fat and cholesterol are reduced.

Description

technical field [0001] The invention belongs to the technical field of enzymolysis and fermentation straw, and in particular relates to a biological feed and a preparation method thereof. Background technique [0002] At home and abroad, there are many experiments on the technology of enzymatically hydrolyzing and fermenting straw to produce pig bio-feed, but few of them are really successful and popularized, especially for lignified yellow straw, which is basically helpless. [0003] Before 2010, the fermentation of straw mainly used microbial degradation, but the effect was limited. In recent years, with the rapid development of enzyme preparation production technology, the production cost of finished enzymes has become lower and lower, the production cost of cellulase unit enzyme activity has dropped by at least 60%, and the production cost of xylanase has dropped by 70%. Above, the fermentation of straw has gradually shifted to the pursuit of enzymatic hydrolysis effect...
