dc.description.abstract
In this study the macroscopic and microscopic structure of the heart of a fast
growing, meat-type turkey line (British United turkeys BUT Big 6) and a wild-
type turkey line (Canadian Wild turkey) were compared. At 8 and 16 weeks of
age, 10 birds of each genotype and sex were sampled. The body mass and heart
mass of the meat-type turkey both increased at a faster rate than those of the
wild-type turkey. However in both turkey lines, the relative heart mass
decreased slightly with age, the decrease was statistically significant only
in the male turkeys. Furthermore meat-type turkeys had a significantly (p <
0.01) lower relative heart mass and relative thickness of the left ventricle
compared to the wild-type turkeys of the same age. The wild-type turkeys
showed no significant change in the size of cardiomyocytes (cross sectional
area and diameter) from 8 weeks to 16 weeks. In contrast, the size of
cardiomyocytes increased significantly (p < 0.001) with age in the meat-type
turkeys. The number of capillaries in the left ventricular wall increased
significantly (p < 0.001) in wild-type turkeys from 2351 per mm2 at the age of
8 weeks to 2843 per mm2 at 16 weeks. However, in the meat-type turkeys there
were no significant changes, capillary numbers being 2989 per mm2 at age 8
weeks and 2915 per mm2 at age 16 weeks. Correspondingly the area occupied by
capillaries in the myocardium increased in wild-type turkeys from 8.59% at the
age of 8 weeks to 9.15% at 16 weeks, whereas in meat-type turkeys this area
decreased from 10.4% at 8 weeks to 9.95% at 16 weeks. Our results indicate a
mismatch in development between body mass and heart mass and a compromised
cardiac capillary density and architecture in the meat-type turkeys in
comparison to the wild-type turkeys.
