Data on the carcass composition of mature male blesbok and kudu shot on two Northern Transvaal nature reserves are presented. The mean live weights of the 22 blesbok and 18 kudu examined were 73,4 kg and 236,3 kg, cold carcass yields 52,9% and 56,6% and lean meat yields 43.4% and 45,4% respectively. Both species were found to be more productive of high quality retail cuts and of lean meat than domestic stock.
