Embodiment 1
[0049] Dry the epimedium, motherwort, dodder, angelica and safflower respectively, then weigh 450 grams of epimedium, 100 grams of motherwort, 100 grams of dodder, 100 grams of angelica, and 50 grams of safflower, slice and mix, The mixed mixture is first subjected to 60-mesh coarse crushing, and then the QYF fluidized bed jet mill is used for cell-level fine crushing, and the mixture is crushed to an average particle size of 25-40 microns (about 350-500 mesh fineness) , and then add 500,000 IU / gram of vitamin A microcapsules 5 grams, 20 grams of 50% vitamin E powder, 8 grams of 99% folic acid, then add carrier zeolite powder (fineness is 100 mesh), the total amount reaches 1000 grams and mix evenly again to obtain the feed additive of the present invention.
Embodiment 2
[0051] The same method as in Example 1, the weights of the raw materials added are: 500 grams of Epimedium, 150 grams of Motherwort, 100 grams of Cuscuta, 100 grams of Angelica, 50 grams of Safflower, 5 grams of vitamin A microcapsules of 500,000 IU / gram , 20 grams of 50% vitamin E powder, 8 grams of 99% folic acid, prepared Chinese herbal medicine compound feed additive according to the preparation method identical with embodiment 1.
Embodiment 3
[0053] The same method as in Example 1, the weights of the raw materials added are: 450 grams of Epimedium, 150 grams of Motherwort, 100 grams of Cuscuta, 100 grams of Angelica, 50 grams of Safflower, 5 grams of vitamin A microcapsules of 500,000 IU / gram , 20 grams of 50% vitamin E powder, 8 grams of 99% folic acid, prepared Chinese herbal medicine compound feed additive according to the preparation method identical with embodiment 1.

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...
