| Abstract | ||||
| Results were built upon the data of 436422 ducklings day-old representing three different strains (Pekin, Muscovy and Khaki-Campbell) located in Behaira, Kafr El-Sheikh, Demietta, Gharbeya, Giza and Dakahlia Govemorates. The data were taken through the 4-23 weeks of age during the period from 1990 to 2000 belonging to ten farms from each of the governmental and private sectors. The traits studied were feed intake (g.feed/duckling/day), feed conversion (g feed/g gain), costs, returns, economic efficiency and production function at the end of rearing period (23 weeks of age). The main results could be summarized as follows: 1-The averages feed intake (g feed/duckling/day) for combined sexes of Pekin, Muscovy and Khaki-Campbell duddings during the period of 4-23 weeks of age were 138.68, 142.55 and 143.01 g, respectively. The seasonal averages of this trait were 137.27, 135.14, 143.02 and 133.91 g in the winter; spring, summer and fall seasons, respectively. The means were 148.83 and 126.46 g for the governmental and private sectors, respectively. 2-The averages feed conversion (g feed/g gain) for combined sexes of Pekin, Muscovy and Khaki-Campbell ducklings during the period of 423 weeks of age were 8.12, 9.93 and 8.79, respectively. The seasonal averages of this trait were 9.29, 8.46, 9.97 and 8.46 for the winter, spring, summer and fall seasons, respectively. The means were 9.24 and 8.34 for the governmental and private sectors, respectively. 3- The fixed costs were 7.96, 6.53 and 7.86% and the variable costs were 92.04, 93.47 and 92.14% from the total costs. The duddings and feed costs are the two most important cost factors, the first item accounts for 15.95, 29.87 and 16.83% and the second item accounts for 59.35, 50.70 and 58.58% from the total costs of producing 100 ducklings. | ||||
