Three stocking rates (12.0, 15.5 and 19.0 ewes/hectare) and 2 lambing times (Sep. and Oct.) were compared in Merino flocks in 1970-72. Ewes lambing in Oct. grew approx. 5% more wool than those lambing in Sep. Lambing time did not affect fertility, but perinatal mortality of lambs was greater in flocks lambing in Sep. than in Oct. Twinning rate and the percentage of lambs weaned decreased as stocking rate increased.
