Embodiment example 1

[0028] A biological feed for promoting estrus initiation of gilts of the present invention is adopted, and 65% of fermented soybean meal, 25% of fermented wheat bran, 1.6% of epimedium, 1.2% of actinolite, 1.0% of rehmannia glutinosa, 1.0% of coix seed, 1.2% Wang Buliuxing, 1.3% Codonopsis, 1.2% Danshen, and 1.5% Astragalus.

[0029] The above-mentioned feeds that have been formulated are added to the special full-price feed for gilts according to the proportion of 20%.

[0030] A feeding experiment was carried out in a large-scale breeding enterprise in Sichuan. 200 LY gilts were selected for the test, and they were equally distributed to two treatment groups according to their body weight and age. Each treatment had 4 repetitions, and each repetition had 50 pigs. They were respectively fed with the control group diet or containing 20% ​​of the biological agent of the present invention. Feed the treatment group diets. The test started from a body weight of 55kg, and the gil...

Embodiment example 2

[0032] Adopt a kind of biological feed of the present invention to promote the start of estrus in gilts, select 70% of fermented soybean meal, 20% of fermented wheat bran, 1.2% of epimedium, 1.5% of actinolite, 1.2% of rehmannia glutinosa, 1.1% of coix seed, Buliuxing 1.0%, Codonopsis 1.0%, Salvia miltiorrhiza 1.5%, Astragalus 1.5%.

[0033] The above-mentioned feeds that have been formulated are added to the special full-price feed for gilts in proportions of 10%, 15%, and 20%, respectively.

[0034] A breeding experiment was carried out in a large-scale breeding enterprise in Guangdong. The test selects 300 LY gilts, and distributes them to 4 treatment groups on average according to body weight and age, each process is replicated 3 times, and each replicates 25 pigs, respectively feeding the control group diet or containing 10% of the present invention, 15%, 20% biological feed treatment group diet. The test started from a body weight of 55kg, and the gilts were identified...

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...
