An interim report is presented where date of lambing has been varied in an attempt to synchronize feed requirements with pasture growth. Lamb growth and ewe liveweights are presented for ewes suckling twins. The ewes were stocked at either 21.3 or 27.7 ewes/ha and had average lambing dates of September 1 or October 1. Later lambing ewes were heavier, had higher intakes, and had higher lamb growth rates in the first month of lactation than did early lambing ewes. Low-stocked ewes also performed better than high stock ewes.
