Abstract |
Three groups of wethers viz. Jamunapari ??Black Bengal ?? (JBB), Selected Black Bengal ??Selected Black Bengal ?? (SBB) and Random Black Bengal ??Random Black Bengal ?? (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 pre-slaughter 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.1. Correlations were compared by Z statistic among three genetic groups and the value of Z did not differ (p>0.05) between groups. |
