	abstract = {The effects of stocking rate (low, L; and high, H), breed (Jersey, J; and  Friesian, F) and age (2, 3, >3 years old) on the intervals from calving to first  ovulation and to first oestrus were assessed in pasture grazed dairy cattle  using a 2 x 2 design. Cows in the FH herd had longer intervals from calving  to first postpartum ovulation (C-ovn1; 49.2 vs 24.7, 31.1 and 29.4 days) and  C-hl (47.1 vs 32.5 days) intervals than older cows, with 3 year old cows  intermediate. The high stocking rate herds had reduced CS, liveweight and  milk production compared to the low stocking rate herds. Condition score  and milksolids production were inversely related to the C-ovnl and/or C-hl  intervals. Increased stocking rates were associated with longer periods of  postpartum anoestrum.  },
