Study compares carcass and meat traits in guinea fowl and pheasants

Version 1

A new Animals study compared carcass composition and meat quality in male guinea fowl and male common pheasants raised under the same production conditions and slaughtered at 13 weeks of age. In a 32-bird trial, the researchers found that guinea fowl had higher body weight, carcass weight, carcass yield, and heavier individual carcass components than pheasants. Pheasants, however, had a higher proportion of breast muscle and neck, while guinea fowl showed greater proportions of leg muscles, wings, and skin with subcutaneous fat, along with a lower meat-to-fat ratio.

Why it matters: For veterinary professionals and animal production teams working with alternative poultry species, the study adds species-specific baseline data that could inform nutrition planning, growth targets, carcass evaluation, and conversations with producers serving niche meat markets. The findings also fit with earlier literature showing that meat traits in guinea fowl and pheasants can vary meaningfully by species, age, sex, and feeding program, underscoring that management benchmarks from chickens don’t always translate cleanly to game birds. More broadly, related work in other alternative poultry species points in the same direction: a recent Animals multi-omics study in meat pigeons found that breed had a much stronger effect than plumage color on carcass traits, water-holding capacity, collagen content, fatty acids, free amino acids, and flavor-associated metabolites, reinforcing that genetics can outweigh superficial traits when evaluating meat quality.

What to watch: Watch for follow-up work with larger sample sizes, female birds, and different rearing systems to see whether these carcass and meat-quality differences hold up across commercial settings. It will also be worth watching for more studies that separate true breed or species effects from visible traits such as plumage color when producers make selection decisions for specialty meat markets.
