Abstract(s)
The control of reproduction activity has a major impact in the management and profitability of sheep farms. There are several synchronization of estrous protocols. The progesterone/progestogens protocols are widely used all over the word. The long term protocols are the most commonly applied. Progestogens are synthetic hormones that mimics the effects of progesterone. The fluorgestone acetate(FGA) is the progestogen most used in Portugal. Progesterone is administered by controlled internal drug release device(CIDR) and FGA by vagina internal pessaries. Consumers sees less progesterone as a health threaten as it is a natural hormone. On the other hand, several investigators found CIDR harder to loss and to cause less vaginitis than the internal pessaries.
