Abstract

The invention discloses a composition for promoting meiotic resumption of oocytes of sows and application of the composition. The composition comprises vectors and extracts of ajuga forrestii, oregano, horseradish, cinnamon, rosemary, dunaliella and rhoeo discolor. The composition and the application have the advantages that meiotic resumption of the oocytes of the sows can be promoted, the quality of the oocytes can be improved, the reproductive performance of the sows can be improved, the reproductive lives of the sows can be prolonged, the composition is favorable for activating c-mos and AMPK (adenosine monophosphate activated protein kinase), accordingly, starting of the meiotic resumption of the oocytes of the sows can be promoted, the quality of the oocytes of the sows can be improved, the conception rates and the pregnancy proportions of the sows can be increased, the reproductive health of the sows can be promoted, the immunity and health conditions of the sows can be improved, and the service lives of the sows can be prolonged; the composition can be added into feed for the sows, so that the quantities of eliminated sows among reservation sows and adult sows due to poor oocyte quality of the sows can be greatly reduced, the sow elimination rate can be lowered, and the service lives of high-parity sows can be prolonged; the costs of pig farms can be reduced, and the productivity of the pig farms can be improved.

Description

technical field [0001] The invention relates to the technical field of animal feed additives, in particular to a composition for promoting meiotic recovery of sow oocytes and its application. Background technique [0002] In the process of intensive pig production in my country, 50% of sows are eliminated after only providing 30-40 weaned piglets, which seriously restricts the sustainable development of pig farms. Increasing sow litter size will significantly improve sow reproductive efficiency. The increase in litter size depends on embryo survival and subsequent fetal development, and embryo survival is determined by oocyte quality. [0003] The development of oocytes begins at the embryonic stage, and after birth, oocytes stay in the germinal vesicle (GV) for a long time. After sexual maturity, oocyte meiosis resumes, the germinal vesicle ruptures (GVBD) and the first polar body is expelled, completing the first meiosis. Studies have shown that mitogen-activated protein...
