Many farmers nowadays have a lot of ewes' low birth rate, which is really anxious. In order to effectively improve the conception rate of ewes, and thus achieve the purpose of improving the reproductive rate of ewes, Xiao Bian has compiled the main reasons for the low rate of ewes, and the corresponding prevention measures.
1. Rams are infertile or the quality of the ram's semen is poor, resulting in fertilization of the ewes but infertility. When farmers choose rams, they choose some rams with poor genetic performance, or some males have an unreasonable proportion of males and females, which leads to excessive mating frequency and low sperm quality.
2. The ewes are malnourished, resulting in abnormal ovulation and ovulation. In the estrus breeding season, some peasants still use sheep to feed, which causes some ewes to be thin and weak, which affects the ewes' ovulation is not normal.
3. After the ewes are estrus, the breeding is not timely, delaying the best time for conception of the ewes. Some sheep farmers have insufficient understanding of the estrus symptoms of the ewes and the estrus ovulation of the ewes, which delays the optimal conception time of the ewes.
4. Ewe disease treatment is not timely, delaying the best estrus season of the ewes. During the estrus breeding season, some common diseases and internal and external parasitic diseases affect the normal sensation of the ewes, which affects the normal estrus of the ewes.
Prevention and treatment measures for ewes with low fertility rate:
1. Perform artificial insemination. Sometimes the quality of the ram's semen cannot be determined. It is best for the farmer to ask the technician to come over and check and timely perform artificial insemination.
2. Strengthen the management of ewes and promote the normal estrus of ovulation of the appropriate age ewes.
3, do not mismatch the timing, timely ate ewes breeding. According to the general rule, the suitable time for ewes to breed is: the sheep are 10 to 15 hours after the start of estrus, and the goats are in the afternoon or the third morning after the start of estrus.
4. The ewe needs to be treated in time.
After understanding these reasons, the most important thing is to choose the ewes' nutrition and rams. According to the corresponding measures, the average ewes' fertility rate will increase.
