Feed additive for improving reproductive capacity of sow and preparation method thereof

Abstract

The invention discloses a feed additive for improving the reproductive capacity of a sow. The feed additive comprises the following raw materials in percentage by weight: 45 to 50 percent of epimedium, 10 to 15 percent of leonurus, 5 to 10 percent of semen cuscutae, 5 to 10 percent of angelica sinensis, 3 to 5 percent of safflower, 0.3 to 0.5 percent of vitamin A, 1 to 2 percent of vitamin E, 0.5 to 0.8 percent of folic acid and the balance of zeolite powder. The invention also discloses a preparation method for the feed additive. The method comprises the following steps of: mixing the epimedium, the leonurus, the semen cuscutae, the angelica sinensis and the safflower; smashing a mixture to a particle size of between 25 and 40 microns; adding the vitamin A, the vitamin E, the folic acid and the zeolite powder; and mixing uniformly. The feed additive prepared by the method has the characteristics of less additive amount and quick response when in use, and can remarkably improve the oestrus rate and the conception rate of the sow, and has no toxic or side effect.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for improving the reproductive ability of sows and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's demand for pork consumption continues to increase, and the supply of live pigs must be increased by increasing the number of sows. According to the current breeding performance of sow breeds and the number of sows in stock, the current supply of live pigs It should be greater than the demand, but this is not the case. In recent years, the current situation of insufficient supply of pork has often occurred, and the price of pork has remained high. In addition to the reasons for epidemic diseases (high mortality) and nutritional reasons (the production performance has not been fully utilized), there are also Low sow productivity is closely related. [0003] The low production capacity of sows is mainly manifeste...

Problems solved by technology

Some scholars (Effects of hormones and Chinese herbal preparations on abnormal estrus in sows and comparative experiments, Huang Zhuan, Chinese Animal Husbandry and Veterinary Medicine, No. 7, 2006) used Chinese herbal medicines to treat sows' anestrus. High dosage, slow drug effect, serious waste and poor palatability, etc., which will cause pigs to eat less or refuse to eat, and the desired effect cannot be achieved.
