Abstract

The invention relates to a feed additive for improving reproduction performance of pregnant sows and a preparing method of the feed additive, and belongs to the field of feed additives. The feed additive is prepared from zeaxanthine, beta-carotene, astaxanthin, soybean oil, starch, sodium alginate, beta-cyclodextrin, polycaprolactone, sodium diacetate, ferrous fumarate, sodium butyrate, coated bacillus subtilis, coated lactobacillus, 2,6-di-tert-butyl-4-methylphenol and corncob powder. The feed additive has the advantages that the immune function state of the pregnant sows is adjusted, the reproduction performance of the pregnant sows is improved, the diarrhea rate and weaning death rate of piglets born by the pregnant sows are decreased, the physique and growth state of the newly-born piglets in the newborn stage are changed, and the survival rate and healthy rate of the newly-born piglets are increased.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a green compound feed additive for improving reproductive performance of pregnant sows and a preparation method thereof. Background technique [0002] With the rapid development of intensive pig industry, sow production has become the most important link in the development of pig industry. Therefore, how to improve the reproductive performance of pregnant sows and the health status of their piglets has become the most concerned issue for farmers. Due to the impact of breeding density, environmental pollution and nutritional conditions, pregnant sows often have low immunity, resulting in low birth weight of piglets, increased stillbirth and mummy fetal rate, which seriously affects the economic effect of the pig industry. At present, the feed additives that improve the production performance of pregnant sows are mainly Chinese herbal medicine compound additives, although t...
