The studies were carried out on 40 males and 40 females from A44 ancestral strain of ducks. Dissection analysis was conducted on 7, 8, and 9-week-old ducks for genetic potential manifestion. Duck carcasses were measured for estimation of correlation coefficients between carcass measurements and tissue content. Trunk and chest measurements of ducks for slaughter were increased over rearing. Sexual dimorphism in trunk and chest width, and chest depth, and also in length, circumference and thickness of shank wasn't noticeably observed in 7, 8, and 9-week-old birds. Male and female carcases were well-muscled. Weel-muscled and lean carcases could obtain choosing to the selection flock the A44 ducks which distinguished by measurements positively correlated with breast and leg muscles content (trunk with neck lenght, breast bone length, chest circumference), but negatively correlated with carcass fatness (chest width)
