title: Pharmaceutical control of reproduction in sheep and goats.
abstract: Small ruminant species such as sheep and goats are short-day breeders, which is a crucial factor affecting the offer of lambs and kids throughout the year. An appropriate management of reproduction allows ewes and does to breed in the spring to increase the supply of product to the marketplace on a year-round basis. Pharmaceutical control of reproduction is possible, usually through administration of hormones or analogues related to the natural estrous cycle, such as progesterone, prostaglandins, and/or melatonin.
