The standard is to prepare 25kg of premix and the components and the use amount are: 1.008-1.602 million IU of vitamin A, 1.60-2.40 million IU of vitamin D, 88-132g of vitamin E, 322.4-33.6g of vitamin K, 11.2-16.8g of thiamine, 48-72g of riboflavin, 11.2-16.8g of cobalamin, 168-252g of nicotinic acid, 4-6g of folic acid, 2, 240-3, 360g of choline, 0.224-0.336g of biotin, 76-114g of pantothenic acid, 80-120g of vitamin C, 2, 000-3, 000g of oil and the balance of corn protein powder. The premix has excellent compatibility, supplements the requirement of white jade snails on vitamins. The premix can be added to feed according to the ratio of 0.25 percent in the total weight of the feed.

Preparation method of highly viscous feeding pregelatinized starch

The invention discloses a preparation method of highly viscous feeding pregelatinized starch, which takes cassava starch as raw material, and comprises the steps of controlling raw material quality, making production technological parameters and taking Na2CO3 as a chemical modifier; the Brabender peak viscosity of the feeding pregelatinized starch produced by the method reaches 1600-degree BU; byadopting the method, additional cost is low and effect is good; and the dosage of the pregelatinized starch prepared by adopting the method in aquatic feeds can be reduced, thus significantly increasing the profit of feeds, and simultaneously reducing loss rate of the feeds in water, improving feed efficiency, lightening water quality pollution, and improving cultivation benefit.

Mineral substance premix of white jade snails

The invention discloses a mineral substance additive premix of white jade snails. The standard is to prepare 25kg of premix, and the components thereof and the use amount thereof are: 240-360g of copper sulfate, 1, 664-2, 496g of ferrous sulphate, 1, 664-2, 496g of manganese sulphate, 1, 720-2, 580g of zinc sulfate, 832-1, 248g of 1% cobalt chloride, 133.36-200.4g of 1% sodium selenite, 384-576g of 1% potassium iodide and the balance of bran cake. The premix has excellent compatibility, supplements the requirement of white jade snails on mineral substances and promotes growth. The mineral substance has no residue and no pollution in snail meat. The premix can be added to feed according to the addition ratio of 0.25 percent in the total weight of the feed.

Preparation method of beta-glucosaccharase

The invention discloses a preparation method of beta-glucosaccharase. The method includes the following steps: selecting Aspergillus niger as parent strain through screening, inoculating the Aspergillus niger, the inoculum size of which is 106-108cfu/g, to bran, rice bran and ammonia chloride, wherein in a solid culture medium prepared from the bran, the rice bran and the ammonia chloride according to the weight percentage of 90-100 percent: 0-10 percent:1-3 percent, the initial water content of the culture medium is 65-75 percent, and the pH is 5.5-6.5, culturing for 48-80h at the temperature of 25-30 DEG C and detecting the activity of beta-glucosaccharase to reach 300-430U/g. The method adopts solid fermentation, uses cheap and rich subsidiary agricultural products as fermentation substrate, simultaneously optimizes the culture medium and culture conditions and achieves high yield of the beta-glucosaccharase under solid fermentation conditions, thus providing scientific basis to the ...
