Chicken eggs represent an important source of protein to the growing
human population and also supply repositories of unique genes that
could be used worldwide. The inheritance of shank feathering trait is
dominant upon non-feathering shank trait in chicken which is based on
two factors: pti-1L and pti-1B that are located on Chromosomes 13, 15,
and 24. Using 185 fertile eggs collected from two genetic lines (shank
feathering and non-feathering shank) of Kurdish chicken, we found
that egg weight highly (P < 0.01) correlated with yolk weight (r2=0.520,
0.704, respectively), albumen weight (r2=0.918, 0.835), and shell weight
(r2=0.626, 0.225). The first two principal components explained the
greatest variance in both the White with shank feathering (85.6% of
total variance) and non-feathering shank (76.5%). Therefore, differences
in the component traits of the eggs between the two genetic lines may
be influenced by the same gene actions as shank feathering trait.
According to these results, the two genetic lines of Kurdish chicken
yield significant differences in the internal traits of eggs.
