Not AvailableA study was conducted to evaluate the effect of feeding differentmetabolizable energy (ME) and crude protein (CP) levels on performance of Aseel chicken during 0 to 8 weeks of age (Juvenile phase). At 1 day old, 432 chicks were randomly distributed into nine groups. Each group had 48 chicks distributed into eight replicates with six birds in each. Maize–soybean meal-based diets with three ME levels (2,400, 2,600 and 2,800 kcal/kg) and three CP levels (16%, 18% and 20%) were fed to birds in a 3×3 factorial design. DifferentME levels had significant effect on body weight gain (BWG), feed intake and feed conversion ratio (FCR). Birds fed diet with 2,400 kcal/kg ME had significantly lower BWG (P<0.004), lower shank length (P<0.0007), higher feed intake (P< 0.0001) and poor FCR (P
