Proestrus estrus metestrus and diestrus.

A flock of ewes is generally mated by a single ram who has either been chosen by a farmer or has established dominance through physical contest with other rams in feral populations. The presence of excess ROS can influence early embryonic development through modification of the key transcription factors that modify gene expressions. In the female reproductive system ROS can impair cellular functions and subsequently interrupt intracellular homeostasis and furthermore lead to cell damages. 0 Review s 1425. Reproduction in non-human mammals is regulated by an estrus cycle. In sheep the length of the estrus cycle ranges from 13 to 19 days and averages 17 days.

Female sheep reproductive system Broad ligament - a tough layer of fibrous tissue containing blood vessels and nerves that serve to suspend the majority of the reproductive tract in the abdomen. Sheep have a cotyledonary synepitheliochorial placenta Entrican and Wheelhouse 2006 whereas humans and mice have discoid haemochorial placentation Carter and Enders 2004. The uterus is the place where the fetus develops. Ovaries produce eggs which pass into the uterus. In these systems 3 to 4 males per 100 females are required. A gilt becomes a breeding female either from an arbitrary time before mating eg.

In systems where males are run with females all year round only 1 male per 100 females will be required for beef and sheep production.
