The article describes a test performed on 69 South African Mutton Merino with the purpose to investigate the reaction of a single administration of PGF2a analogue on the duration of oestrus, conception, influence on the development of the corpus luteum and the secretion of progesterone after a synchronised oestrus when injected at different stages of the oestrus cycle. The results are discussed in detail and the general conclusion is that fertility obtained after the synchronised oestrus was substantially lower than normal. PGF2a treatment had no effect on the function of the corpus luteum during the subsequent oestrus cycle since the production of progesterone in all groups was normal
