Abstract in English
Two experiments were carried out to determine the effect of flock
age on egg laying pattern, floor laying, egg weight, hatchability,
fertility and body weight at hatch. Eggs were collected from 32and
43 wk old Cobb 500 broiler flocks for 6 consecutive days hourly to
study egg laying pattern and floor laying (experiment 1). In
experiment 2, 2916 eggs from the flock at 32 ,43 and 49 wk old
were used to determine the effect of flock age on egg weight,
hatchability, fertility and body weight at hatch.
