Sheep's flirting features

The ram is sensitive to the pheromones secreted by the estrus ewes. The ram chases and sniffs the urine of the genitals of the ewes, and anti-lip curling occurs. Sometimes the fore-limb slaps the ewes and sends out courtship calls, while doing crawling. When the ewes are in estrus, some actively approach the rams, or the rams do not move when chasing, the ewe are small, the rams panic when chasing, and the rams do their best to pursue mating. Therefore, since the ewes are not obviously estrus, artificial rams should be used to find ewes when using artificial assisted mating or artificial insemination.
