Abstract:Retained placenta refers to the fact that the placenta fails to be expelled within the physiological time limit of the third stage of labor after the mother animal gives birth to the fetus. This is a common disease in yak farming. I take white yak's placenta as an example. We used motherwort decoction to treat 20 cases. This explores the current prevention and treatment measures and treatment effects of retained placenta diseases in white yaks. This is expected to provide a theoretical basis for white yak afterbirth.
