Abstract
Results were built upon the data of 436422 ducklings day‌old represented three different strains (Pekin, Muscovy and Khaki‌Campbell) located in Behaira, Kafr EI-Sheikh, Demietta, Gharbeya, Giza and Dakahalia Governorates. The data were taken through the production period from 1990 to 2000 belonging to ten farms from each of the governmental and private sectors. The traits studied were age (weeks) at 10%, 50% and age at the peak of egg production. The main results could be summarized as follows: The average ages for the Pekin, Muscovy and Khaki-Campbell ducks at 10 % egg production were 25.33, 26.94 and 25.06 weeks, at 50 % egg production were 30.59, 34.35 and 29.74 weeks and at the peak of egg production were 37.16, 45.88 and 42.68 weeks, respectively. It was observed that the age at the peak of egg production was reduced by 8.72 and 5.52 weeks in Pekin ducks compared to Muscovy and Khaki-Campbell ducks, respectively. The corresponding means for the governmental and private sectors were 25.61 and 25.32 weeks at 10 % egg production, 31.65 and 29.76 weeks at 50 % egg production and 38.43 and 42.53 weeks for age at the peak of egg production, respectively. The birds of the private sector reached peak of egg production later than the governmental ones due to the fact that the second sector used a definite lighting programs.
