Biological fodder for promoting replacement gilt heat start, preparation method and application

Abstract

The invention discloses biological fodder for promoting replacement gilt heat start, a preparation method and application. The biological fodder is prepared by mixing fermented soybean meal, fermented wheat bran and Chinese herbal medicines (herba epimedii, actinolite, prepared rehmannia root, coix seed, cowherb seed, dangshen, the root of red-rooted salvia and astragalus membranaceus) according to a ratio. The materials in the biological fodder have the weight proportion range that the fermented soybean meal accounts for 60 percent to 70 percent, the fermented wheat bran accounts for 20 percent to 30 percent, and the Chinese herbal medicines account for 10 percent, wherein the Chinese herbal medicines have the weight proportion range that the herba epimedii accounts for 1.0 percent to 1.8 percent, the actinolite accounts for 1.0 percent to 1.5 percent, the prepared rehmannia root accounts for 1.0 percent to 1.5 percent, the coix seed accounts for 1.0 percent to 1.2 percent, the cowherb seed accounts for 1.2 percent to 1.4 percent, the dangshen accounts for 1.2 percent to 1.5 percent, the root of red-rooted salvia accounts for 1.2 percent to 1.5 percent and the astragalus membranaceus accounts for 1.2 percent to 2.0 percent; the Chinese herbal medicines are prepared by picking, cleaning, drying, superfine grinding and mixing. The biological fodder is high in product safety degree, is added into a complete compound feed recipe according to a ratio of 15 to 20 percent, and can obviously promote the replacement gilt heat start, increase a replacement gilt estrus rate and reduce the replacement gilt cultivating cost.

Description

technical field [0001] The invention relates to the technical field of animal feed preparation, in particular to a biological feed for promoting the start of estrus in gilts, a preparation method and application thereof. Background technique [0002] In actual production, the proportion of non-estrus or delayed estrus of gilts is as high as 20-30%, which directly affects the economic benefits of pig production. The pressure of disease infection and unbalanced nutrition in large-scale pig farms are the key to the lack of estrus or delayed estrus in gilts. [0003] Patent 201410704367.1 discloses a feed additive for improving estrous performance of gilts, including soybean isoflavones, kudzu root extract, genistein, fructose, and glucose. The feed additive formula provided by the invention is reasonable and innovative, suitable for the growth and physiological characteristics of gilts, and after application, the silent estrus rate of gilts is significantly reduced, thereby im...
