The breast meat of a chicken is very white in
color, whereas the breast meat of a wild duck is
dark red. Why is the reason or reasons for this
difference?
The difference reflects only the function
and not domestication. Ducks fly long
distances and so the meat has a higher
percentage of Type I fibers, whereas
chickens don't fly much and their breast
muscle is mainly Type llb.
None of these reasons adequately
explains the difference.
The difference reflects both function and
the effects of breeding. Ducks fly long
distances and so the meat has a higher
percentage of Type I fibers, whereas
chickens don't fly much and their breast
muscle is mainly Type IIb. A second reason
is that chickens are bred to have "whiter"
white meat.
The difference reflects primarily the
effects of breeding. Chickens are bred to
have "whiter" white meat. The function of
the muscle has little or nothing to do with
the difference in color.
