Abstract
Plasma creatine kinase (CK) activity, an indicator of skeletal muscle damage was correlated with live weight (LW) and muscle yields in 37 different chicken lines representative of 3 categories; broiler (B), layer (L) and traditional (T). Measurements on these lines were made at 6 and 10 weeks of age. Significant increases in plasma CK activity associated with age were observed across all lines and were removed by regression on LW. Differences in CK activity between B lines and the other two categories were not removed by linear regression on LW. The results indicate that alterations in muscle membrane integrity have occurred in B lines that can not be explained by LW alone, and that there is a greater degree of muscle damage associated with the B lines than L and T lines (P<0.01). It is proposed that genetic selection for improved growth rate and
muscle yield in modern broiler lines has detrimental effects upon muscle function and membrane integrity and may be attributable to genetically induced alterations in muscle fibre status.
