Problems solved by technology

But this preparation method usually only uses one kind of bacterium to carry out one conversion, and the conversion rate of inorganic zinc into organic zinc is low, only 30%-60%, which affects the use effect

Embodiment 1

[0010] A preparation method of an organozinc enzyme preparation. The method is as follows: 81 parts by weight of bran, 13 parts by weight of soybean meal, 0.9 part by weight of rice husk powder, 0.6 part by weight of ammonium sulfate, 0.4 part by weight of potassium dihydrogen phosphate, malt 4 parts by weight, the ratio of 110 parts by weight of zinc sulfate solution with a mass percentage concentration of 0.55% is mixed with the above materials to obtain a mixture. After stirring evenly, when the water content of the mixture is insufficient, add water to the mixture with sterile water. Make its water content be 65% by weight, then, under the condition that pressure is 0.18MPa, temperature is 125 ℃, carry out high temperature and high pressure sterilization for 43 minutes, after sterilization, when above-mentioned material is cooled to 38 ℃, inoculate 2.3% of its weight of Candida utilis (Candida utilis) aspergillus strains, stirred evenly and cultivated at a temperature of 29...

Embodiment 2

[0012] A preparation method of an organozinc enzyme preparation. The method is as follows: 85 parts by weight of bran, 11 parts by weight of soybean meal, 1.1 parts by weight of rice husk powder, 0.4 parts by weight of ammonium sulfate, 0.6 parts by weight of potassium dihydrogen phosphate, malt 2 parts by weight, the proportioning of 90 parts by weight of zinc sulfate solution with a concentration of 0.57% by mass. Mix the above materials to obtain a mixture. After stirring evenly, when the water content of the mixture is insufficient, add water to the mixture with sterile water. Make its water content be 55% by weight, then, under the condition that pressure is 0.22MPa, temperature is 115 ℃, carry out high temperature and high pressure sterilization for 46 minutes, after sterilization, when above-mentioned material is cooled to 36 ℃, inoculate 2.7% of its weight of Candida utilis (Candida utilis) aspergillus strains, stirred evenly and cultivated at a temperature of 27°C for ...

Embodiment 3

[0014] A preparation method of an organozinc enzyme preparation. The method is as follows: 83 parts by weight of bran, 12 parts by weight of soybean meal, 1.0 part by weight of rice husk powder, 0.5 part by weight of ammonium sulfate, 0.5 part by weight of potassium dihydrogen phosphate, malt 3 parts by weight, the ratio of 100 parts by weight of zinc sulfate solution with a mass percentage concentration of 0.56% is mixed with the above materials to obtain a mixture. After stirring evenly, when the water content of the mixture is insufficient, add water to the mixture with sterile water. Make its water content be 60% by weight, then, under the condition that pressure is 0.20MPa, temperature is 120 ℃, carry out high temperature and high pressure sterilization for 45 minutes, after sterilization, when above-mentioned material is cooled to 37 ℃, inoculate 2.5% of its weight of Candida utilis (Candida utilis) aspergillus strains, stirred evenly and cultivated at a temperature of 28...

Abstract

The invention provides a method for preparing an organic zinc enzyme preparation. The method comprises the following steps of: mixing materials such as bran, bean pulp, powdered rice hulls, solution of zinc sulfate and the like to obtain a mixture, stirring uniformly, then performing high-temperature high-pressure sterilization, inoculating a koji plate strain of Candida utilis after the sterilization, stirring uniformly and then culturing, then taking a cultured material out, inoculating a koji plate strain of Aspergillus usamii, culturing again, taking a subcultured material out, inoculating a koji plate strain of bacillus subtilis, stirring uniformly and then culturing for the third time, and oven-drying and crushing a material obtained by the culturing for the third time to obtain the organic zinc enzyme preparation. In the method, a production technology is simple, the production cost is low, the three bacteria are adopted for three continuous transformations, and the transformation ratio from inorganic zinc to organic zinc is up to over 98 percent. The prepared enzyme preparation integrates organic trace elements, an enzyme preparation and probiotics into a whole, and can increase the disease resistance of raised animals and promote the healthy growth of the raised animals.

Description

technical field [0001] The invention provides a method for preparing an organozinc enzyme preparation. Background technique [0002] Adding the "life element" of zinc to the feed will have a good biological effect. The zinc source added by people in the early days was inorganic zinc, such as zinc sulfate and zinc oxide. Later, it was found that organic zinc salts are easier to be absorbed and utilized by animals, such as zinc gluconate and zinc citrate, etc., which are the second-generation zinc additives. After entering the 21st century, amino acid chelated zinc or amino acid chelated zinc has entered the field of feed additives with more superior functions, becoming the third generation of zinc element additives. However, the production process of amino acid complexed zinc or amino acid chelated zinc is complicated, and the production cost is relatively high. Now there is a preparation method of organic zinc enzyme preparation, which is to use fungi, bacteria and other ...
