Two-tooth ovulation rate and hogget oestrus activity were
measured on two flocks in 1975 and reproductive performance was recorded
for surviving ewes in 1977-79. 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.
