First, time constraints. The deadline for estrus and mating of razor clams is usually March 15. Since then, the body function has changed due to temperature increase. Even if there is estrus, the mating behavior cannot be implemented smoothly. Moreover, the “mood” of public money has changed at that time. Basically, it is impossible to play a breeding function. Therefore, after March 15th, farmers can abandon the management of estrus-free locusts and consider timely skin-peening.

Second, the situation is unknown. The performance of individual estruss is always inconspicuous or incomplete. The more anemic breeders become, the more anxious they are at the end of the situation, and some will be eager to “trace” frequently, and some will simply put the storks into the public chanting cage. In order to complete the mating. As everyone knows, doing so will only be counterproductive. The reason is that if the breeding pheasants do not reach the height of estrus, they will not accept the public mating behavior. Frequent “taste” and artificial “improvement” will not reach the desire to complete mating. Because of the antipathy of the species, the situation will be reduced or disappeared, and some will be bitten with the public to cause harm.

Third, drug assistance. For some species that are not always estrus, some farmers have adopted feeding aphrodisiac drugs to make them estrus and forced to mate. Practice shows that this is futile and undesirable. Although some of the aphrodisiac drugs can cause estrus symptoms in the species, they will not conceive after mating, and they will not be able to give birth. This is because, under the action of drugs, although the species of quail has estrus, it does not ovulate at all. Natural conception is not possible. Some breeders, after feeding aphrodisiac drugs for the species, have taken compulsory measures such as tying up and fixing the species, and then mating the male crickets. This is even more counterproductive. It simply cannot achieve the purpose of conception and should be resolutely prohibited.
