Department of Animal Science, University of Ibadan, Nigeria *Corresponding author's Email: richardwura@gmail.com Received: 19 May 2016 Accepted: 16 June 2016 ABSTRACT Present experiment was conducted to evaluate the effect of diets containing different levels of metabolizable energy (3000, 3100 and 3200 kcal metabolizable energy/kg) and crude protein (20, 22, 24 and 26% crude protein) on performance of growing Japanese quail. 288 two-week old quail chicks were assigned into 12 treatments and 3 replicates with 8 birds in each. Birds were randomly allocated to each dietary treatment. For 3000, 3100 and 3200 kcal metabolizable energy/kg levels of energy, crude protein levels of 26, 24, 22 and 20% were assigned. Data on performance and nutrient digestibility were recorded and analyzed using a completely randomized design with a 4×3 factorial arrangement during 6 weeks of age. Metabolizable energy significantly affected (P < 0.05) total and daily feed intake. Level of crude protei...
