Sheep's Feelings and Artificial Assisted Mating Technology

The breeding can be carried out throughout the year, but spring and autumn are the best. The mating methods of sheep are "natural mating" (this article) and "artificial insemination". At present, the method of natural mating is generally adopted in rural areas. Natural mating is not okay, but don't let it be freely mated. It is best to artificially assist in mating after the trial. Now the technique of the trial situation and the manual assisted mating are introduced as follows: The trial situation is to choose a ram that is physically strong, has a strong sexual desire, is free from disease, is aged 3 to 4 years old, and has good production performance. The mission of the ram is to find the ewes. In order to avoid stealing, the rams were tied to the test cloth. The trial cloth used white cloth 35 centimeters long and 30 centimeters wide, and the four corners were attached with belts. Whenever the courtship was performed, they fell under the belly of the trial sheep, making it impossible to mate directly. Tests should be conducted every morning. Try the ram to sniff the ewes with their noses, or use their hoofs to tease the ewes, and even climb across the ewes' backs. The ewes do not move, do not run, do not refuse, or extend their hind legs to urinate. Such ewes are Estrus sheep. Estrus sheep should be pulled out of the sheep and immediately numbered or marked. Artificial assisted mating Through trials, the ewes of the estrus should be singled out in separate bars or other places to allow them to mate with designated rams. The selected species of rams should be fed with high-quality protein feeds in advance to improve management and increase the amount of exercise so that they can have vigorous energy. After the ewes and rams are put together, they can be applied to the ram's nose with urine or secretions of the ewes to stimulate their sexual desire and promote sexual intercourse. One of the benefits of trial and assisted mating is that the rams with good breeds and high quality can be selected to help improve the quality of the lambs; second, the best time for breeding can be grasped to ensure the fertility rate; and the third is the number of males and females. Both the date and the breeding date can be recorded, the date of the birth can be predicted, the management is convenient, the lambing is facilitated, and the survival rate can be increased.
