Conteúdo: 	Two-tooth ovulation rate and hogget oestrus activity were measured on two flocks in 1975 and reproductive performance was recorded for surviving ewes in 1977-9. Twin ovulators were on average 2 kg heavier than single ovulators and hogget oestrous activity was positively related to May hogget weight. Weight differences diminished but did not disappear with time. Within both flocks a small but positive phenotypic relationship existed between early indicators of increased fertility and subsequent mature reproductive performance.
