Energy requirement of 144 8-week-old exotic ISA ESSOR Guinea fowls (Numida meleagris) in a hot savanna climate was determined. Three levels of metabolisable energy (ME) with equal crude protein (CP) level of 160 g CP kg-I were offered during the second growth phase (8- 15 weeks of age). The ME levels were EI, 10.88; E2, 11.30; and E3, 11.72 MJkg-' dry matter. The mean final live weight (EI, 1898 g; E2, 1906 g; E3, 1936 g), mean live weight gained (EI, 613 g; E2, 620 g; E3, 650 g), mean daily feed intake (EI, 131 g; E2, 130 g; E3, 133 g), and feed conversion ratio «EI, 8.33; E2, 8.78; E3, 8.91) recorded did not differ significantly during 8-15 weeks of age at different energy levels. Similarly, the mean slaughter weight (EI, 2043.75 g; E2, 2075.00 g; E3, 2112.50 g), mean bled weight (El, 1950.0 g; E2, 1975.00 g; E3, 1993.80 g), mean dressed weight (EI, 1393.75 g; E2, 1412.50 g; E3, 1435 g), and mean dressing percent(E I, 68.2 %; E2, 68.0 %; E3, 67.9 %) recorded did not differ significantly (P 0.05). Also, the differences (P0.05) among mean tissue fat (EI, 17.84 %; E2, 17.91 %; E3, 18.96 %) and protein (EI, 25.79 %; E2, 25.66 %; E3, 24.49 %) on the various energy levels were not significant. Based on this study, it is recommended that 10.88 MJkg .) dry matter metabolisable energy should be adopted as desirable during 8-15 weeks of age to save cost of production
