Understanding reproduction in goats is essential to increasing productivity, which is largely a function of pregnancy rate, the number of offspring born and weaned and the frequency with which kids are produced. Therefore, goat reproductive management should produce a high level of fertility (greater than 90 percent) and an optimum litter size (two kids) with a high rate of survival to weaning. Understanding reproductive processes in the goat will help producers manage their herd …

Exposure to males after a period of isolation — at least three weeks and one mile away — can be used for induction and synchronization of estrus during the breeding and non-breeding season without additional treatments in goats. The physiological basis for this response is due in part to smell and sight, with neither stimulus completely accounting for the response. It is not effective if the males and females are together …

Progestagens are reproductive hormones like ones that are used in birth control for women. Progestagens are a form of the natural progesterone produced in the body. Various forms of progestagens with different routes of administration have been used for estrus (heat) synchronization. It can be used to extend the lifespan of the corpus luteum during the breeding season when goats are already cycling and it is required for getting goats to show estrus and breed in the non-breeding …

Estrous Synchronization Prostaglandin


Prostaglandin

This hormone is naturally secreted from the non-pregnant uterus of the goat during the estrous cycle. It lyses (destroys) the corpus luteum so the cycle can start over. It is also secreted when it is time for birthing to help with the birthing process. Early studies with few animal numbers have shown that prostaglandin and similar hormones can be used for synchronization in cycling females. Studies have shown that during the breeding season, prostaglandin administered at a dose of …
