Study compares carcass and skeletal traits in Pekin, Muscovy ducks

A newly published paper in Animals adds another side-by-side comparison of two of the world’s best-known meat ducks, Pekin and Muscovy, with a broader lens than many earlier studies. Published June 20, 2026, the study evaluated carcass composition, meat quality, digestive tract morphometry, and leg bone dimensions in 40 broiler ducks, split evenly by genotype and sex. According to the journal abstract, genotype had a significant effect on carcass weight, dressing percentage, and the share of neck, wings, and skin with subcutaneous fat. (mdpi.com)

That focus matters because Pekin and Muscovy ducks occupy distinct roles in meat production. Extension and poultry references consistently describe Pekin, Muscovy, and their hybrids as the main duck types used for meat, with Pekins typically reaching market weight faster and Muscovies producing leaner carcasses. Cornell’s duck research materials also note that Muscovy ducks are genetically distinct from common ducks such as Pekins, and that Muscovy-common duck hybrids are sterile but valued for lean meat production.

The new paper appears to build on that production context by looking beyond simple carcass yield. In addition to carcass traits and physicochemical meat properties, the authors assessed internal organ development, intestinal measurements, texture parameters, and selected femur and tibia dimensions. That broader design is notable because earlier duck research has often examined carcass and meat quality alone, while separate studies have looked at digestive traits or bone-related measures. A recent poultry science paper from some of the same research orbit similarly examined carcass composition, digestive tract morphometry, and leg bone dimensions in spent parent Pekin ducks, suggesting a growing interest in how body composition, gut development, and skeletal structure interact in duck production.

The findings also fit with prior literature showing consistent genotype effects between Pekin and Muscovy ducks. Earlier comparative work has reported that Muscovy ducks tend to have leaner carcasses and different muscle and meat-quality characteristics than Pekins, while Pekins are widely recognized for rapid growth and commercial efficiency. Other published comparisons have found genotype-linked differences in water, protein, fat, collagen, color, tenderness, and muscle structure, which helps explain why this new paper’s combined carcass, digestive, and skeletal approach could be useful for production specialists.

I did not find a separate institutional press release or formal outside expert commentary tied specifically to this June 2026 paper. Still, the broader industry and academic context points in the same direction: duck genotype is not a minor variable. Poultry extension resources emphasize that Pekin and Muscovy ducks differ in growth trajectory, fatness, and feeding needs, and older digestibility research suggests that the two genotypes can process feed ingredients differently during growth. Taken together, that supports the practical relevance of the new study, even without a public expert response attached to this publication yet. (poultry.extension.org)

Why it matters: For veterinarians and technical advisors in poultry systems, the study is a reminder that genotype can influence multiple management domains at once, including carcass targets, gastrointestinal development, and skeletal traits that may intersect with mobility and welfare. In a production setting, that can affect how teams think about feed formulation, growth benchmarks, processing expectations, and how aggressively to monitor leg health or conformation issues in different duck lines. The paper is small, with 40 birds, so it should not be overgeneralized. But it adds useful comparative evidence that breed-specific biology still deserves attention in duck health and production planning. (mdpi.com)

What to watch: The next step is whether researchers link these genotype-associated anatomical differences to commercial outcomes such as feed conversion, gait and lameness measures, condemnations, or welfare indicators, and whether breeders or nutrition teams use that evidence to further differentiate management between Pekin, Muscovy, and hybrid meat ducks.
