[0002] Cows usually give birth naturally, but sometimes, due to the large fetus or the small size of the calf, human intervention is often needed to perform different degrees of midwifery. In actual production, the proportion of dystocia is generally about 10%. When the amniotic fluid ruptures and the calf has not been delivered for 2 hours, the cow's hoof has not progressed after 20 minutes of exposure, or the calf's tongue turns purple, take midwifery measures in time. Before assisting the cow in giving birth, the delivery room should be thoroughly disinfected, and the pulling, pushing, and correction instruments and ropes used for midwifery should be disinfected.
