Normally 4 to 6 hours later, the animal will be in estrus and 12 hours will reach estrus. 2. The fake ram method. Put a ewes that are in heat and seeking mating into the adult ewes. Because of the impulsiveness of courtship, ewes often chase and crawl across other ewes in the ram's posture. These ewes can enter the estrus state continuously after being stimulated by such guidance. 3. Body guidance method. The estrus-free ewes will be consciously placed in the rams group to allow the rams to chase and climb, which can effectively promote the estrus of the ewes.
