Abstract
To know the carcass quality and proximate composition of Nellore brown lambs under three systems of rearing i.e. intensive, semi-intensiveand extensive system.36 Nellore brown lambs of 3 months age from Livestock Research Station, Mamnoor, Warangal district were randomly allotted to three rearing systems i.e. Intensive (G1), Semi-intensive (G2) and Extensive (G3) system of each 12 animals. The mean dressing percent of lambs on pre slaughter and empty body weight was 52.23 ± 0.56, 47.29 ± 0.33 and 44.13 ± 1.27; 62.63 ± 0.66, 59.19 ± 0.29and 56.57 ± 0.88, respectively in G1, G2 and G3 groups. The dressing percentage of the lambs had significant (p < 0.05) effect between G1 and G3 group and had no significant (p < 0.05) effect between G2 and G3 group. The mean weight (kg) of skin was significantly (p < 0.05) higher in G3 (2.07 ± 0.03) group than G1 (1.76 ± 0.06) and G2 (1.73 ± 0.05) group. The total non- edible offals weight (kg) was higher in G3 than G1 and G3 group and had no significant (p < 0.05) effect between the three groups of the study.
