	abstract = {Milk yield and composition were measured weekly throughout  lactation, and daily dry matter intake (DMI) on 7 occasions, for Friesian  (n=16) and Jersey (n=16) heifers calving at either high (H) or low (L)  liveweights. During the 8 weeks pre-partum, heifers were fed to achieve  calving liveweights of 404 (H Friesian), 354 (L Friesian), 334 (H Jersey) and  277 (L Jersey) kg. All heifers were fully fed on pasture as one group for the  whole of lactation. Calving liveweight had no effect on average DMI over the season. Average  DMI was higher for Friesians than Jerseys while average liveweight- corrected DMI was slightly greater for Jersey than Friesians. Average daily  milk yields and yields of lactose were lower for L than H heifers. Solids- corrected milk yields and yields of milkfat and protein were unaffected by  calving liveweight, but milkfat \% and protein \% were higher for L than H  heifers. The Friesians had higher milk yields, and yields of protein and  lactose, but lower milkfat \% and protein \% than Jerseys. No effect of restricted feeding during late pregnancy in heifers was  demonstrated on milk solids production in the subsequent lactation.},
