Resumo
This experiment aimed to evaluate internal and
eggshell quality collected from hens of different lines and
ages. A total of 48 white eggs obtained in a commercial farm
from four genetic lines (Babcock B300, Hy Line W36,
Lohmann white e Hisex) in three different ages (29.60 and
69 weeks) were allotted in a completely randomized design
in a 4x3 factorial arrangement. Egg weight, percentage of
yolk, albume and eggshell, albume height, specifc gravity
and Haugh unit were measured and means were compared
by Tukey test. Babcock B300’ eggs showed higher Haugh
unit (97.23) and albume height (6.68 mm) values as compared
to Hisex (84.46 and 8.19 mm, respectively). The egg yolk
percentage from Hy line W36 hens (29.63%) at 69 weeks of
age were greater (p<0,05) than Babcock B300 (26.28%), Hisex
(26.43%) and Lohmann White (26.58%). This study indicates
that egg weight increased and Haugh unit and albume height
reduced in older hens for all lines. The eggshell quality was
reduced in aged hens.
