[0001] The invention relates to a feed for pigs, in particular to a compound feed for improving the estrus rate of sows and a preparation method thereof. Background technique

[0002] With the rapid development of the pig industry, the degree of intensification of the breeding process is getting higher and higher, and the requirements for feed are also increasing. When preparing feed, it is necessary to consider reducing the cost of raw materials, but also taking into account the ratio of nutrition and utilization. Maximize the breeding benefits. However, most of the existing pig feeds have the problem of unbalanced nutritional ratio. After long-term consumption of pigs, they are prone to indigestion, growth retardation, frequent diseases, etc., and also increase the cost of breeding. It has caused a waste of resources. In addition, there are also problems such as excessive addition of trace elements and abuse of hormone drugs, which not only pollute the envi...
