Abstract :

The study was designed to determine the meat yield and dressing percentage of young rams aged 24 months belonging to three breeds i.e. Turki, Afghan Arabi (AA) and Baluchi, from Afghanistan. Data collected from 36 animals (12 rams each from Turki, AA and Baluchi) during February to May, 2011. Pre-slaughter live weight of Turki, AA and Baluchi was about 49.33 ± 0.31, 45.83 ± 0.49 and 40.71 ± 0.66 kg, respectively and were significantly different (P 0.05). Rams Body Condition Score (BCS) data showed that all the selected animals were almost of similar body conditioned. Carcasses weights were significantly higher (P 0.05) in Turki than the other two breeds (27.79 ± 0.25 kg versus AA 24.80 ± 0.26 kg and Baluchi 21.13 ± 0.35 kg). Dressing percentage of Turki (56.33 ± 0.44%) was significantly higher (P 0.05) than AA (54.11 ± 0.18%) and Baluchi (51.90 ± 0.22%). Proportion-wise weights of various parts in dressed carcasses of three breeds revealed that Baluchi sheep had the highest proportional weights of the body components, followed by AA and Turki. Mutton proportion were found significantly higher (P 0.05) in Fore and Hind limbs of Baluchi sheep. Fat tail proportion contributed significantly (P 0.05) higher 23% of carcass weight in Turki sheep as compared to 7% in Baluchi sheep. AA hooves weight (0.82 ± 0.004kg) was significantly higher from the Turki (0.77 ± 0.01) breed rams, however, little variation appeared from Baluchi (0.81 ± 0.007kg ) rams. Fore limbs weight of Turki breed was significantly higher (4.94 ± 0.04 kg) than AA (4.57 ± 0.04kg) and Baluchi (4.26 ± 0.07kg) while weight of hind limbs of Turki was higher than Baluchi and AA (6.91 ± 0.06, 6.44 ± 0.11 and 6.19 ± 0.05kg, respectively). Collective weight of Neck, Ribs and Brisket of Turki sheep (5.46 ± 0.04 kg) was significantly higher than AA (5.16 ± 0.06kg) and Baluchi sheep (4.87 ± 0.08kg). Weight of loin area of Turki sheep (2.17 ± 0.01kg) was significantly (P 0.05) higher than AA and Baluchi sheep (1.71 ± 0.03 and 1.94 ±0.02 kg) respectively. The results of present study revealed that Turki breed had better potentials for mutton production under Afghanistan conditions than AA and Baluchi.
