The studies were carried out on 480 Peking ducks from the paternal A44, A55 and maternal P66, P77 strains. The birds were housed indoors on a slatted floor. Concentrate mixtures for ducks were provided ad libitum. Ducks from the investigated strains characterized by a great body weight. In the 9th week of ducks' life males weighed beyond 3 kg, and females 2.85 kg. Up to the 9th week, feed intake per one duck and per 1 kg of body weight ranged from 11.9 to 13.6 kg, and from 3.8 to 4.1 kg, respectively. Slaughter yield was from 66.2 to 70.1 percent but females characterized by a greater slaughter than males. Proportion of breast and leg muscles in ducks' carcasses increased together with the age of birds and was from 24.8 to 28.0 percent in the 9th week of life. Skin with subcutaneous fat content was stated from 21.3 to 28.9 percent of carcass, and it was mostly greater in females within each strain
