Growth rate and meat qualities of hybrid ducklings from crossing of domestic and German lines of ducks of the Peking breed have been studied. It is established, that the best results have been received at crossing of drakes of combination NT1 with ducks of combination T2N. At cultivation of hybrid ducklings received at crossing of drakes of combination NT1 with ducks of combination T2N the live weight of ducklings 3284 g is reached at expenses of forage of 2.87 kg. At 49 - day age hybrid ducklings of combination NT1 x T2N surpass ducklings of cross Temp in live weight on 161 g, or on 5.2%. at decrease in expenses of forage on 0,19 kg, or 6.2%. So, the output of viscerated carcass at them was above on 2.3%, pectoral muscles - on 2,4%, and skin with hypodermic cellulose has decreased on 2.3%. In carcasses of these ducklings the fat content was on 4,17% less, and a protein on 19.7% more than in the control. The obtained results allow to recommend these combinations for further breeding to perfect cross Temp for the increase of live weight and improvement of meat qualities of ducklings
