	abstract = {Single and twin lamb growth rates, herbage mass and quality were monitored 3-5 times from birth to weaning on 6 farms in the southern North Island. Lambs (n = 50-80/farm) were tagged and weighed at birth, and ewes (n = 20-50/farm) grazing with the monitored lambs were tagged and weighed from docking. The average live weight gain (LWG) from birth to weaning was 273 g/d (229-311) and 220 g/d (152-279) for single and twin lambs respectively (P<0.001) and remained relatively static over the lactation period. Mean herbage energy concentration averaged 10.5 MJME/kg DM during the first two months of lactation but had declined to 8.9 by weaning (P<0.001). In conclusion, twin lamb growth rates on hill country are considerably lower than those of single lambs. },
