Abstract

The invention discloses a compound feed and a compound feed additive for reducing the limb disease in sows and a preparation method thereof. The method comprises the following steps of sintering driedrice husks in the anaerobic environment to form carbonized rice husks; then adding the carbonized rice husks to a composite enzyme preparation for enzymatic hydrolysis, taking the husks out and draining, pouring the husks into a composite trace element aqueous solution for immersing, then taking the husks out for freeze drying and breaking and adding calcium dihydrogen phosphate and calcium lactate after pulverization to obtain a first material; pulverizing green whole plant corn and then uniformly mixing the corn with a fermenting agent for sealing fermentation, adding the first material, alfalfa meal and multivitamin evenly after fermentation, then conducting freeze drying and pulverizing, adding carboxymethyl dextran and sodium tripolyphosphate for even mixing to obtain the compound feed additive for reducing the limb disease in sows.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a compound feed for reducing limb and hoof diseases in sows, a compound feed additive and a preparation method of the compound feed additive. Background technique [0002] Pig limb and hoof disease, also known as pig limb weakness syndrome and pig lameness, refers to the general term for pig limb and four hoof disease, which is relatively common in pig production. Pigs grow and develop rapidly, and as their weight increases rapidly, the pressure on their hooves increases rapidly. The main symptoms of this kind of disease are abnormal standing, gait and posture of sick pigs, and it is difficult to support the body weight, so that the breeding pigs cannot continue to be used, and can only be eliminated, which affects the production efficiency of the pig herd and seriously damages the economic benefits of the pig industry . [0003] Under the modern pig raising mode, pigs ...
