	abstract = {This study endeavoured to characterise the effects of breed and  calving liveweight (CW) on postpartum (pp) ovarian activity in 16  Friesian (F) and 16 Jersey (J) heifers. Half of the animals within each  breed were differentially fed (High vs Low: H vs L) during the 8 weeks  before calving to achieve CWs (24 h pp) of 404 (FH), 354 (FL), 334 (JH)  and 279 (JL) kg. They were fully fed as one group after calving.  Ovarian ultrasonography showed that the FL group had the longest  postpartum anovulatory interval (PPAI) of 77 days compared to 47 days  among other groups. The second dominant follicle pp emerged 6 days  later in FL heifers. Breed, but not CW, affected follicle patterns in  the first normal oestrous cycle. Underfeeding of Friesian heifers  during late pregnancy extended the PPAI whereas Jerseys were not  affected to the same extent.   },
