摘要：
Three groups of wethers viz. Jamunapari male xBlack Bengal female (JBB), Selected Black Bengal male xSelected Black Bengal female (SBB) and Random Black Bengal male xRandom Black Bengal female (RBB) of 1 year old were evaluated for pre-slaughter traits and carcass characteristics. The correlations between pre-slaughter traits and carcass traits were computed. It was found that the preslaughter weights of JBB and SBB were almost similar in yielding hot and chilled carcass as well as dressing percentage (DP). RBB wethers were lighter (p <0.05) than JBB and SBB in pre- and post-slaughter weights and also inferior (p <0.05) in DP. SBB wethers were found to produce more visceral fat compared to JBB and RBB. Other variety meats appeared erratic in yield.l. Correlations were compared by Z statistic among three genetic groups and the value of Z did not differ (p <0.05) between groups.
