Abstract

The invention discloses a feed additive used for raising litter size of sow, and belongs to the technical field of the feed additive. The feed additive is characterized by comprising: by mass, beta-carotene 12.67-17.3%, vitamin e 63.37-43.2%, vitamin b2 20.28-34.5%, biotin 0.26-0.34%, vitamin b12 0.06-0.41%, and folic acid 3.36-4.25%. The preparation method includes mixing the beta-carotene, Ve, Vb2, biotin, Vb12, and folic acid, fully stirring the mixture to mix uniformly, and adding the feed additive in the conventional feed from 3 days after ablactation of the sow to mating and from mating to 19 days after mating. The feed additive can promote sow to ovulate, improve the live embryo number, growth the cervix uterus length of sow, enlarge the space occupied by the embryo in uterus, so that the litter size of sow can be increased. The practice shows that the litter size of sow can increase 2-3, and the feed additive has good economic benefit.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a feed additive for improving the litter size of sows. Background technique [0002] At present, domestic large-scale pig farms mainly use imported breeds for crossbreeding. After crossbreeding, imported pig breeds have fast production speed, high lean meat rate, and good social and economic benefits. The main problems are: the low reproductive rate of imported pig breeds, far Far from satisfying the demand of pig farms for imported pig breeds. At present, most pig farms achieve the effect of producing more piglets by increasing the number of imported sows. Due to the increase in the number of imported sows, it not only increases the cost, but also increases with the number of sows fed. The increase in the number resulted in a significant increase in the incidence of disease. Contents of the invention [0003] Aiming at the problem of low reproductive rate ...
