✦ Synopsis
Energy and protein requirements of guinea keets (Numida meleagris) in a hot humid climate were determined involving one day-old keets of three varieties : Pearls, Lavender and White. Nine dietary treatments combining three levels of metabolisable energy (ME) and crude protein (CP) were oþ ered during each growth phase (0-4, 5-8 and 9-12 weeks of age). Crude protein levels were P 1 , 220, 200 and 180 ; 200, 180 and 160 ; and 180, 160 and 140 g kg-1 dry mash for respective phases, P 2 , P 3 , while ME levels were 12.13 and 12.55 ; 11.72 and 12.13 ; and 11.30 and 11.72 MJ kg-1 dry E 1 , E 2 , E 3 , matter for 0-4 and 5-12 weeks of age, respectively. The live weight gain during 0-12 weeks of age at diþ erent energy levels 751 ; 775 and 755) were comparable, but those at diþ erent protein (E 1 , E 2 , E 3 , levels 847 ; 804 and 633) were diþ erent (P AE 0.01). Keets fed either 180 g or 160 g CP kg-1 (P 1 , P 2 , P 3 , during 9-12 weeks of age had similar gains. Feed conversion ratios (FCR) during 0-12 weeks on E 1 P 1 (3.50), (3.47) and (3.47) did not diþ er signiücantly. At 4 weeks of age, FCR on the three E 2 P 1 E 3 P 1 energy levels were similar but the cumulative FCR on (3.67) and (3.65), although similar, were E 1 E 2 improved (P AE 0.05) compared to that on (3.87). Thus, the requirements of ME are 11.30 and 12.13 E 3 MJ kg-1 dry mash during, 0-4 and 5-12 weeks of age with 220, 200 and 160 g CP kg-1 during 0-4, 5-8 and 9-12 weeks of age, respectively. 1999 Society of Chemical Industry
