abstract = "Modified incubation factors affect skeletal musculature development of
broiler chickens during embryonic and postnatal periods of development.
These changes appear to have great influence on the proliferation of
myoblasts and muscle growth after hatching. In this study, the
histomorphological and -morphometric parameters of broiler chicken leg
musculature, after thermal and light treatments during embryogenesis,
were examined. The applied treatments included thermal manipulation
(exposure of fertilized eggs to increased temperature), light
manipulation (exposure of fertilized eggs to monochromatic green light)
and simultaneous thermal and light manipulations. Following the specific
parameters that were observed, it was determined that in the late
postnatal period of development, treated groups have a larger diameter
and smaller nucleocytoplasmic ratio of muscle cells compared to those of
the control group, in which fertilized eggs were incubated at a constant
temperature of 37.8 degrees C, without light. Diameter was increased by
4.20\%, 3.77\% and 4.55\% on day 42 after hatching in thermal, light and
combined thermal and light treated groups, respectively, compared to the
control. The nucleocytoplasmic ratio was increased by 37.5\% on day 42
after hatching in the control group compared to all treated groups. The
volume density of the muscle connective tissue was approximately at the
same level between the groups. It can be concluded that thermal and
light treatments stimulate the proliferation of myoblasts and enhance
development and growth of leg muscles in broiler chickens.",
