The single-crown erection of the rooster, the single crown of the hen and the smaller crown. The crown, ear and lobe are red, and the cormorants, embryos and toes are yellow. Big broiler is a large-scale mixed-use variety. Second, production performance 1. Meat production performance: The adult cock weighed 2.9 kg, the adult hen had 2.3 kg, and the 6-month-old cock reached 76.67% of the annual weight, and the hen reached 77.59%. Big broilers have good meat performance, even distribution of subcutaneous fat, and tender meat. Its half-net slaughter rate was 77.80% for roosters, 73.45% for hens, 75.69% for roosters with whole net slaughter, and 70.88% for hens. 2. Egg Production Performance: Big bone chickens have the prominent characteristics of large eggs, with an average annual egg production of 160 eggs, weight of 62 to 64 grams, and a high of 70 grams or more. Under better feeding conditions, up to 180 pieces. Eggshell dark brown, thick and solid shell, low breakage rate. The ratio of eggs to eggs is 1:3.0 to 3.5. 3, reproductive performance: cock 6 months of sexual maturity, weighing about 2.2 kilograms, hens about 180 to 210 days production, male and female breeding ratio of 1:8 to 10. Egg fertilization rate was 90%, hatching rate of fertilized eggs was 80%, 60-day-old brooding rate was over 85%, nesting rate was 5% to 10%, and nesting duration was 20 to 30 days. Big-broiled chickens are excellent local chickens that can be used concurrently. Care should be taken to preserve the seed and strengthen breeding so that their excellent performance can be further improved. At the same time, the large-bone chicken can be used as a female parent, and the introduced layer chickens can be used as male parents to crossbreed so that a better cross combination of both meat and eggs can be selected for both meat and eggs, thereby exploring the ways of crossbreeding of large-bone chickens.
