The aim of this experiment was to determine the fattening performance and carcass characteristics of Angora goat x Coloured mohair goat cross-breed F, male kids (genotype 1) and male Coloured mohair kids (genotype 11). Genotype groups were divided into two sub-groups. Total daily feed intakes of kids in genotype Ia (n = 5) and IIa (n = 9) were 40% concentrate and 60% forage whereas total feed intake of kids in genotype Ib (n = 5) and IIb (n = 9) were 60% concentrate and 40% forage. Fattening lasted 90 days. Daily live weight gains and feed efficiencies (1 kg live weight gain/feed intake) of genotype Ia and Ib were 39.20 and 56.20 g; 8.01 and 7.41 kg, respectively. Daily live weight gains and feed efficiencies of genotype Ila and lib were 53.33 and 79.00 g; 6.64 and 7.41 kg, respectively. Cold dressing percentages, percentages of leg, back, loin and fat on kidney were 40.8, 41.9, 43.3 and 45.5% (p<0.05); 29.2, 31.5, 32.1 and 31.9% (p<0.05); 5.5, 6.0, 6.8 and 6.7% (p<0.05); 5.6, 6.5, 6.1 and 6.4%; 1.6, 3.7, 2.2 and 3.0% (p<0.001) for genotype Ia, Ib, IIa and IIb respectively. It can be concluded that Coloured mohair kids had better daily and total gains and kids fed 60% concentrate had the higher performance compared with others.
