Normally 4~6 hours later, heat will be able to reach heat and 12 hours will reach estrus. 2. 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 form of rams. After being induced to stimulate, these ewes can enter the estrus state one after another. 3. Body induction 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.
Hormone aphrodisiac method: 1. Implantation method.
