Problems solved by technology

[0004] The object of the present invention is to provide a green pollution-free pig feed and its preparation method. The raw materials used in the pig feed include a large amount of discarded crude fiber and macromolecular protein. The compound enzyme preparation decomposes crude fiber and macromolecular protein, not only can reasonably control the reaction conditions to make the enzymatic hydrolysis complete, but also decomposes the decomposed small molecule sugar and amino acid peptide chain base by adding an appropriate amount of isophorone diisocyanate Sexual cross-linking and fixation, so that the nutrients after enzymatic hydrolysis will not be lost, which effectively solves the problem that the existing pig feed is usually directly added with compound enzyme preparations in order to realize the rapid digestion of pigs, which is used to digest the crude fiber and macromolecules in the feed. However, the environment acidity and temperature of different enzyme preparations are different, and the acidity in the gastric juice is strong, which easily affects the activity of the enzyme, which in turn causes the enzyme preparation to have a weak force, resulting in crude fiber and Large molecular protein is difficult to digest. At the same time, some existing pig feeds directly use small molecular digestible substances, but these substances are expensive and costly. Some pig feeds are first decomposed by enzymes and then decomposed by enzymes during the preparation process. Pressing, but the small molecular substances produced by enzymatic decomposition will be lost through the solvent during the preparation process, and enter the problem of reducing the nutrition of pig feed

[0031] The specific preparation process of the quaternized ammonium salted crab shell is as follows:

[0032] Step 1: Take 10kg of crab shells, wash them, dry them and grind them, add the ground crab shells to 100L of hydrochloric acid solution with a concentration of 5mol / L and soak for 12 hours, and stir continuously during the soaking process to make the calcium in the crab shells Dissolving, then filtering, washing and drying to obtain pretreated crab shells;

[0033] Step 2: Add the pretreated crab shells obtained in step 1 into a 40% sodium hydroxide solution, heat up to 50° C. for deacetylation reaction for 6 hours, then filter, wash and dry to obtain chitosan;

[0034] Step 3: Add the chitosan prepared in step 2 to a 5% acetic acid solution to form a chitosan solution with a concentration of 0.05g / mL, and then add 2,3-cyclone to the 100L chitosan solution Oxypropyltrimethylammonium chloride, stirred and reacted at 50°C for 7h, filtered, washed and dried to obtain quat...

[0036] A preparation method of green pollution-free pig feed, the specific preparation process is as follows:

[0037] In the first step, 59kg of bagasse, 37kg of soybean meal, 45kg of wheat bran, 38kg of alfalfa grass and 27kg of distiller's grains were dried and crushed to a particle size of less than 1cm;

[0038] In the second step, edible vinegar is added into water and configured into a solution of pH=5.8-6, then 2.3kg of cellulase and 1.2kg of xylanase are added thereto, and bagasse, wheat bran, Add alfalfa grass and distiller's grains into the solution, raise the temperature to 55°C and stir at a low speed for 72 hours, then filter, dry the filter residue for later use, and keep the filtrate for later use;

[0039] In the third step, add 34kg of cornmeal and the residue filtered in the first step into water, adjust the pH=8.2-8.5, add 4.2kg of alkaline protease to it at the same time, raise the temperature to 50°C and stir at low temperature for 3 days, and filter the ...

Embodiment 3

[0043] A preparation method of green pollution-free pig feed, the specific preparation process is as follows:

[0044] In the first step, 63kg of bagasse, 41kg of soybean meal, 51kg of wheat bran, 42kg of alfalfa grass and 29kg of distiller's grains were dried and crushed to a particle size of less than 1cm;

[0045] In the second step, edible vinegar is added into water to be configured into a solution of pH=5.8-6, then 2.8kg of cellulase and 1.4kg of xylanase are added thereto, and bagasse, wheat bran, Add alfalfa grass and distiller's grains into the solution, raise the temperature to 55°C and stir at a low speed for 72 hours, then filter, dry the filter residue for later use, and keep the filtrate for later use;

Abstract

The invention discloses a green nuisance-free pig feed. The green nuisance-free pig feed comprises the following raw materials in parts by weight of 59-63 parts of bagasse, 34-38 parts of corn flour,27-29 parts of distillers' grains, 37-41 parts of soybean meal, 45-51 parts of wheat bran, 38-42 parts of alfalfa, 2.3-2.8 parts of cellulase, 1.2-1.4 parts of xylanase, 4.2-4.5 parts of alkali protease, 18-21 parts of quaternisation crab shells, 0.6-0.8 part of trace elements, 21-22 parts of isophorone, 17-18 parts of glycidyl trimethyl ammonium chloride, 5-7 parts of table salt, 1.3-1.5 parts ofcomplex vitamins and an appropriate amount of water. The used raw materials comprise massive waste crude fibers and macromolecule protein, in the process of preparation of a pig feed, the crude fibers and the macromolecule protein are directly decomposed through a compound enzyme preparation, and the reaction condition can be reasonably controlled, so that the enzymolysis is thorough; an appropriate amount of the isophorone is added, so that micromolecule sugar and amino acid peptide after decomposition, are subjected to alkaline cross-linking fixation, and nutrient substances after enzymolysis cannot run off.

Description

technical field [0001] The invention belongs to the field of pig feed preparation, and relates to a green pollution-free pig feed and a preparation method thereof. Background technique [0002] In the pig industry, pig feed can provide the necessary nutrients and vitamins for the growth and development of pigs, so that pork is rich in nutrients and can supplement the nutrients and trace elements necessary for the human body. [0003] In order to reduce the harm to the human body, the existing pig feed usually uses green and pollution-free feed. During the feed preparation process, the crude fiber, oil and other substances are directly crushed and fermented, and then trace elements are added to realize the green and pollution-free pig feed. , but the pure green and pollution-free pig feed is prone to mildew when placed in a humid environment for a long time, which will cause certain harm to the health of pigs, and the existing pig feed is usually directly added with compound ...
