This invention belongs to the field of livestock and poultry feed technology, specifically disclosing a high-efficiency compound feed for fattening pigs that resists disease and prevents diarrhea, and its preparation method. The feed includes corn, soybean meal, wheat bran, compound functional premix, vegetable oil, dicalcium phosphate, fish meal, salt, citric acid, maifanite, and zeolite. The compound functional premix contains ferrous sulfate, manganese sulfate, copper sulfate, calcium iodate, lysine, Enterococcus faecalis, and Bacillus subtilis. The Enterococcus faecalis and Bacillus subtilis are prepared using a multi-layer coating process. This invention utilizes the above-mentioned high-efficiency compound feed for fattening pigs that resists disease and prevents diarrhea, and its preparation method. This compound feed, through the scientific ratio of compound functional premix and basic feed, combined with innovative multi-layer coating technology and metal loading intercalation technology, achieves efficient colonization of probiotics and synergistic antibacterial effects, significantly improving the intestinal health and production performance of fattening pigs.

The invention discloses a production system and method of calcium iodate, and belongs to the technical field of chemical synthesis and separation. The production system of the calcium iodate comprises a reaction kettle, a stirrer, a neutralization tank, a synthesis tank, a filter, a dryer and a crusher. The production method of the calcium iodate comprises the following steps: 1, producing potassium hydrogen iodate from potassium chlorate and iodine, 2, neutralizing the potassium hydrogen iodate with potassium hydroxide to produce potassium iodate, 3, reacting the potassium iodate with calcium chloride to produce a calcium iodate suspension, and finally, filtering and drying to obtain potassium iodate monohydrate. According to the method, a chlorine oxidation method, a hydrogen peroxide oxidation method and an electrochemical oxidation method are not needed, the second step and the third step can be carried out under normal pressure without heating except for heating for producing the potassium hydrogen iodate, and special equipment is not needed. No three wastes are discharged in the whole production process, and meanwhile, a byproduct potassium chloride can be produced.

The invention provides a sustained-release bar for repairing mammary glands in the early stage of dry milk of dairy cows and a preparation method thereof, and belongs to the technical field of veterinary pharmaceutical preparations. The breast repair slow-release bar for the dairy cow in the early stage of dry milk is prepared from the following raw materials in parts by weight: 6 to 10 parts of compound plant extract, 10 to 15 parts of ferroferric oxide, 8 to 12 parts of magnesium oxide, 6 to 10 parts of zinc sulfate, 1 to 5 parts of hordenine hydrochloride, 1 to 5 parts of manganese sulfate, 0.05 to 0.15 part of calcium iodate, 0.05 to 0.15 part of sodium selenite, 0.5 to 2 parts of calcium stearate and 3 to 10 parts of vegetable oil. The breast repair slow-release bar for the dairy cow in the initial dry period can effectively promote emptying and involution of breasts of the dairy cow in the dry period, the involution period is remarkably shortened, the risk of mastitis infection in the dry period is reduced, and the repair effect of the breast repair slow-release bar is better than that of natural milk stop.

The invention relates to the technical field of potassium iodate recovery, and discloses a potassium iodate waste liquid recovery treatment method, which comprises: collecting a potassium iodate production waste liquid, and clarifying the potassium iodate production waste liquid to obtain a clarified filtrate; stirring the obtained clarified filtrate and a pre-prepared soluble calcium salt solution for reaction to obtain calcium iodate precipitation slurry; carrying out solid-liquid separation on the obtained calcium iodate precipitation slurry to obtain a calcium iodate filter cake; stirring and reacting the obtained calcium iodate filter cake with a pre-prepared potassium carbonate solution and water to obtain a reaction mixed solution; carrying out solid-liquid separation on the obtained reaction mixed solution to obtain a potassium iodate solution; and carrying out crystallization treatment on the obtained potassium iodate solution to obtain potassium iodate. The method provided by the invention improves the recovery rate of iodine, avoids the use of toxic barium salt, reduces the generation of solid wastes, and realizes the resource utilization of waste liquid.
