Synchronization of oestrus in cattle, sheep and goats using a prostaglandin analogue.

Abstract

Prostaglandin F~(Y, (PGF2a) causes luteolysis in several species of animals including cattle and sheep. This has led to investigations with PGF2a as an agent for the control of oestrus and ovulation in domestic animals (Inskeep 1973) and to comparison of PGF2a and progestins as practical methods of synchronizing oestrus in cattle (Smith 1973). This paper reports preliminary studies of the use of a synthetic prostaglandin analogue (ICI .79939) in synchronizing oestrus and ovulation in sheep, cattle and goats.
