dc.descriptionFourty, thin-tail lambs (mean BW 13 .8 ± 1 .1 kg) were used in an experiment to measure energy and protein requirements. Lambs were divided into four dietary treatments in a 2 x 2 x 2 factorial design in which the factors were sex (male vs female), energy levels (high vs low) and crude protein (high vs low) . Metabol izable energy (ME) and crude protein (CP) requirements were measured by regression technique, using data collected during the experiment . Results showed that combination of low protein and high energy diet gave the highest response, i.e . 112 g daily gain with better feed convertion, i .e . 5 .4 . Equation models developed to predict ME and CP requirements were EM (MJ/head) = -11 .9266 - 0 .6487 BW °." (kg) + 38 .48 ADG (kg) + 4 .6887 log ME/CP (J/g) and CP (kg/head) = 8 .14766 - 0.10642 BW "5 (kA+ 6 .05777 ADG (kg) - 1 .39541 log ME/CP (J/g) . Predicted ME and CP requirement, for maintenance were 482 kJ/kg BW 0.75 and 5 .14g/kg BW 5 respectively .   Key words: Energy, crude protein, sheep, growing phaseen-US
