The aim of the study was to evaluate the effect of three different dietary energy levels on dry matter intake, milk production and composition of early lactating Friesian cows at University dairy farm Peshawar. Nine multiparous early lactating (10±5days in milk) cows were selected and divided into three groups with three animals in each group with three dietary energy levels, (E-100%), (E-88%) and (E-112%); respectively. High DMI (P<0.05) was recorded for diet E-112 (13.78±0.17kg/day) followed by diet E-100 (13.14±0.12kg/day). Significantly high milk yield (14.80±0.10lit/day) was observed in diet E-112 and lower milk yield (13.01±0.10kg/day) for diet (E-88%). High milk fats (3.91±0.02%) were found at low energy diet and no statistical difference found among other composition of milk. It was concluded that diets containing high dietary energy above than the recommended ME level by NRC for early lactating cows can increase DMI and milk yield under local environment of Peshawar.
