Autumn is the golden season for estrus mating of ewes. The proper mating of ewes of the right age is the most effective measure to increase the quaternary birth rate and multi-crop rate.
1. Select breeding goats to use a litter of ewes as a species, to maintain the characteristics of sheep breeds.
2. Before mating, sow ejaculate age 1 month before mating, short-term excellent feeding should be carried out, each supplement 0.2 ~ 0.25 kg per day. Only escaping females of the right age have good estrus, normal oestrus, and increased number of ovulations, which can increase the quasi-fetal rate and multiple lambs rate of the ewes.
3. Grasping the appropriate period of autumn yak sheep breeding is a good time for grabbing autumn fleas. Grasping autumn oysters can significantly increase the number of ovulation of ewes. Rams have a strong libido, a lot of semen quality, and quasi-fetal rates. The multiple birth rate increased, the estrus estrus concentrated, and more ovulation.
4. The timing of estrus in a timely breeding game is 24 to 40 hours, and the ovulation time is 30 to 34 hours after the start of oestrus. Therefore, timely breeding time should be 12 to 25 hours after estrus. Older ewes have short estrus duration and should be bred early after estrus. Young ewes have a longer estrus time, and breeding time should be later.
5. The practice of compounding is generally performed within one estrus period. Fertilization can be performed once the animals are bred. However, in order to increase the quasi-fetal rate and multi-crop rate, two breedings can be performed in the middle and late stages of the estrus estrus, or two or three breeding rams can be used each at one time during one estrus period.
