How to breed sheep in autumn

Autumn is the golden season for ewes to mate in estrus. Timely scientific breeding of ewes at the right age is the most effective measure to improve the parity rate and litter rate of ewes.

1. Choose to keep the breeding sheep? Ewes with multiple lambs were selected as seed to maintain the breed characteristics of multiple lambs at one birth.

two。 Fattening before mating? Ewes of appropriate age should be given short-term optimal feeding one month before mating, and each ewe should be supplemented with 0.2-0.25 kg concentrate per day. Only when the ewe of the right age has a good body condition, the estrus can be normal and the number of ovulation will increase, thus the quasi-pregnancy rate and litter rate of ewes can be improved.

3. Grab the autumn fat? The suitable time for mating of sheep is a good time to grab autumn fat, which can significantly increase the number of ovulation of ewes, exuberant sexual desire of rams, good quality of semen, increased rate of quasi-pregnancy and multiple births, concentrated estrus and more ovulation.

4. Breeding at the right time? The duration of estrus in each sheep is 24-40 hours, and the time of ovulation is mostly 30-34 hours after the beginning of estrus, so the timely mating time should be 12-25 hours after estrus. The oestrus duration of old ewes is relatively short, so it should be mated as early as possible after estrus, while the ewe of young ewes should be in estrus for a long time, and the mating time should be later.

5. Rematch? Generally in a period of estrus, once mating can be fertilized and pregnant. However, in order to improve the quasi-pregnancy rate and litter rate, ewes can be mated twice in mid-estrus and late estrus, or in different periods of a single estrus. Huo Rui
