Abstract
1. Male and female broiler chickens of a pure line were selected over one generation for low or high plasma, cardiac-derived troponin T conc entrations at 12 h of age. 2. Heritability of plasma troponin T was mo derately high (h(2) = 0.38 +/- 0.06), and there was no difference in m ean body weights of parents (G(0)) of the 2 lines at 4 and 19 weeks of age. 3. This preliminary study suggests that broiler breeder companie s will be able to select for resistance against heart damage and ascit es.
