Abstract

The present invention discloses a feed additive for promoting estrus, ovulation and fertilization of pigs and furred furred animals. The feed additive comprises a Chinese herbal extract, multivitamins, organic chromium, enzyme production probiotics, phytase, composite betaine, essential amino acids and a carrier; and the additive is prepared from the following components, by weight: 4 to 6 parts of angelica, 1.5 to 2.5 parts of epimedium grandiflorum extract, 1.5 to 2.5 parts of leonurus artemisia extract, 2.5 to 3 parts of actinolite, 2 to 3 parts of nutsedge, 2 to 3 parts of dodder, 1.2 to 2 parts of vitamin E, 1.5 to 2.5 parts of vitamin A, 0.03 to 0.05 part of sodium selenite, 0.01 to 0.03 part of biotin, 10 to 15 parts of organic chromium, 2 to 3 parts of enzyme production probiotics, 1.5 to 2.5 parts of phytase, 2 to 3 parts of complex betaine, 1.5 to 2.5 parts of methionine, 2 to 3 parts of lysine, and 100 parts of carrier. By adopting the Chinese herbal extract, the multivitamins, the organic chromium and the enzyme production probiotics, the feed additive has effects of improving sexual function of sows and furred animals for breeding, promoting estrus, follicular maturation and superovulation of dams, improving conception rate and litter size of breeding stock, and significantly improving reproductive performance of breeding stock.
