Abstract

The invention discloses a microecological preparation increasing the sow estrus rate and preparation method and application thereof. The microecological preparation is prepared from butyrivibrio fibrisolvens, enterococcus faecalis, lactobacilli and bifidobacteria. The butyrivibrio fibrisolvens, the enterococcus faecalis, the lactobacilli and the bifidobacteria obtained through separation in Meishan sow faeces are subjected to enlarging cultivation in liquid fermentation tanks respectively to obtain bacterium liquid, different kinds of bacterium powder are mixed according to the weight ratio of 1 to 0.5-2 to 1-3 to 1-3 after drying and colony counting, and the microecological preparation is prepared through ultrafine smashing, screening, coating and quality detecting. The preparation is high in product safety degree, 300-500 g of the preparation is added into each ton of sow feed, the day age of estrus of replacement gilts can be earlier, the estrus rate of the replacement gilts and weaning sows is increased, the heat interval of the weaning sows is shortened, oocyte quality is improved, and the breeding rate is increased.

Description

technical field [0001] The invention relates to the technical field of animal feed additives, in particular to a microecological preparation for improving sow estrus, a preparation method and application. Background technique [0002] Microorganisms can directly or indirectly control the functions of the host body, such as energy acquisition, shaping the host immune system, metabolism of exogenous substances, and release of metabolic signals. Meishan pig is an excellent local pig breed in my country, which has the characteristics of early sexual maturity, high estrus rate and large number of litters. Our recent experiments found that when Meishan sows were in estrus, the number of B. fibrinolyticus, Enterococcus faecalis, Lactobacillus and Bifidobacteria in their feces increased significantly compared with that before estrus. Bacillus fibrolyticus is a cellulolytic bacterium, which, like Lactobacillus, can produce acetic acid through fermentation, thereby increasing the syn...
