Understanding the characteristics and differences between common poultry breeds used in layer production, including their egg-laying capacity and adaptability to different environments.
Poultry Breeds – Study Notes
| Category | Primary Purpose | Representative Breeds | Key Characteristics |
|---|---|---|---|
| Layer | High egg output (260‑320 eggs/yr) | Leghorn, White Plymouth Rock, ISA Brown, Hy‑Line Brown | Efficient feed‑to‑egg conversion, early onset of lay (≈18 wk), often white or brown eggs |
| Broiler | Fast growth for meat (5‑7 lb in 6‑8 wk) | Cornish Cross, Ross 308, Cobb 500 | Broad breast, rapid feed intake, high feed conversion ratio (FCR ≈ 1.6–1.8) |
| Dual‑Purpose | Moderate meat & egg production | Rhode Island Red, Plymouth Rock, Sussex, New Hampshire | Good egg numbers (200‑250 yr) and decent carcass size; hardy and adaptable |
| Heritage / Traditional | Preservation of historic genetics, often slower growth | Dominique, Black Bantam, Old English Game, Dorking | Longer laying period, better for free‑range, strong foragers |
| Ornamental / Show | Aesthetic traits, exhibition | Silkie, Polish, Frizzle, Sultan | Unique feathering, crests, feathered feet; not production‑focused |
| Specialty | Specific market niches (e.g., high‑omega‑3 eggs) | Araucana (blue/green eggs), Marans (dark brown eggs) | Egg color or other niche traits |
| Breed | Primary Use | Weight (male/female) | Notable Traits |
|---|---|---|---|
| Broad Breasted White | Commercial meat | 30–40 lb / 15–20 lb | Fast growth, large breast, white feathers (no dark pinfeathers) |
| Broad Breasted Bronze | Heritage meat | 28–38 lb / 14–18 lb | Dark meat, strong flavor, good for free‑range |
| Narragansett | Dual‑purpose | 20–25 lb / 12–15 lb | Dark plumage, good for small farms |
| Royal Palm | Ornamental | 12–15 lb / 8–10 lb | Long, curved tail; prized in shows |
