title: Characterisation of embryonic cardiac-derived troponin T in broiler chicks bled one to 168 hours after hatching.
abstract: Troponin T, a cardiac-specific protein released only from damaged or injured heart tissue and cells, was measured in the sera from fowl chicks bled one, 12, 24, 48, 96 and 168 hours after hatching. A peak troponin T response was observed 12 hours after hatching in two experiments conducted six months apart. In the second experiment the heterophil/lymphocyte (H/L) ratios were also increased at one and 12 hours after hatching. The data suggest that the troponin T response in chicks bled 12 hours after hatching, together with the raised H/L ratios at the same age, may indicate a physiological stress reaction to the process of hatching, rather than a process which is under direct genetic control.
