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
