Twenty yearling F^ crossbred of West African long legged (WALL) X South East dwarf (SED) of Nigeria were grouped according to their live weight (20.9±1.7kg), and offered one of the 5 concentrate rations as a supplement to the low quality, dry season forage, of mixed grass/legume hay (mainly 3 part Pennisetum purperum and 1 part Centrosema pubescens) for a growth period of 56 days, after which 5 of the lambs were relocated to the metabolism cages for digestibility and nitrogen balance trials. The Mangifera indica kernels were substituted for maize offal in the diet A,B,C,D and E of 0,15,30,45 and 60%, respectively. The concentrate intakes and growth rates were 951,961,1017,1225 and 1001 g/day; and 116,125,146,162 and 116g/d, respectively, with higher utilization of protein, fibre, ether extract and NFE in supplemented groups.
