Feed additive for breeding-swine

Abstract

The invention aims to provide a preparation method of a Chinese herbal medicine feed additive capable of enhancing the reproductive performance of breeding-swine. The feed additive comprises followingraw materials in parts by weight: 10 to 15 parts of gorgon fruit, 20 to 25 parts of raw rehmannia root, 15 to 20 parts of morinda officinalis, 5 to 10 parts of Chinese chive seed, 10 to 15 parts of eucommia, and 30 to 40 parts of medical stone powder; commonly, 10 parts of gorgon fruit, 25 parts of raw rehmannia root, 15 parts of morinda officinalis, 5 parts of Chinese chive seed, 10 parts of eucommia, and 35 parts of medical stone powder. The preparation method comprises following steps: adding Chinese chive seeds and eucommia into water with an equal weight, boiling for two hours; then filtering the decoction, concentrating the decoction until concentrate accounting for 50 wt.% of the original decoction is obtained; subjecting gorgon fruit, raw rehmannia root, and morinda officinalis toultrafine grinding; evenly mixing the concentrate, medicinal powder obtained in ultrafine grinding, and medical stone powder under stirring, and sieving the mixture by a 100-mesh sieve.

Description

technical field [0001] The invention relates to a feed additive, in particular to a Chinese herbal medicine feed additive for improving the reproductive performance of breeding pigs. Background technique [0002] With the development of the pig industry, more and more large-scale breeding groups pay attention to the improvement of the reproductive performance of breeding pigs. In the breeding process, give full play to the potential production performance of breeding pigs, so as to create better economic benefits for pig farms. Among them, the reproductive performance of breeding boars is very important. The breeding of breeding boars requires that they have good breeding ability and can The output is large, dense and high-quality semen. And pay more attention to sows, do not hesitate to increase the production cost to improve the reproductive performance of sows, but the production performance of breeding pigs raised in many intensive pig farms is relatively poor, so it is...
