Abstract

Days elapsed from the mid point of the anoestrous period to first (DF) and last (DL) oestrus of the breeding season and duration of this breeding season (DD) within a flock of 60 adult Lincoln ewes are reported in this note. All traits showed considerable variation and the phenotypic correlation between DF and DD was −0·57 (P < 0·01) while that between DL and DD was 0·87 (P < 0·01). However, DF was not correlated with DL (P = 0·10).
