Abstract
1. Cardiac troponin T is a recently developed serological marker used as a sensitive diagnostic tool for early myocardial damage in ‘at risk’ human patients. 2. Serum troponin T values were measured in young 30‐d‐old broilers with ascites and in healthy age‐matched flockmates. 3. The data showed a significant increase (P< 0.001) in troponin T values in ascitic broilers compared with control birds. A similar increase in the arterial pressure index in ascitic birds indicated a good positive correlation at this age. 4. The results suggest that this new assay cross‐reacts with chicken cardiac troponin T antigen and that it may be an important indicator of myocardial cell damage for use in future genetic selection programmes in the combat against ascites.
