title: A preliminary estimate of the heritability of plasma troponin T in broiler chickens.
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 concentrations at 12 h of age. 2. Heritability of plasma troponin T was moderately high (h2 = 0.38 +/- 0.06), and there was no difference in mean body weights of parents (G0) of the 2 lines at 4 and 19 weeks of age. 3. This preliminary study suggests that broiler breeder companies will be able to select for resistance against heart damage and ascites.
