How long does it take for ewes to start estrus or mating after giving birth?

Measures to improve fertility rate

( 1)

Control estrus

By controlling estrus, the estrus of sheep is basically the same, and ewes can breed according to their own needs and give birth to lambs in a predetermined time. The mechanism of estrus control is to interfere with the reproductive physiological process of ewes with hormones or hormone-like drugs, change the periodicity of their natural estrus, and make all ewes treated with drugs concentrate on estrus and ovulation at the same time within the specified time.

Estrus induction

During the seasonal estrus of ewes, exogenous hormones are used to make ewes estrus normally. This can shorten the breeding cycle. You can have lambs twice a year or three times a year.

Activation of sexual function of ram

When some rams reach sexual maturity, even after physical maturity, their sexual activity is still abnormal. In order to activate the sexual function of these rams, it is necessary to graze and feed the sheep reasonably, especially to mix feed and diet according to nutritional standards and exercise reasonably. Using exogenous hormone therapy to increase the concentration of testosterone in blood can also play a role in activating sexual function.
