摘　　要：以赤水黑羽乌骨鸡群中发现的携带ｄｗ基因的矮小型黑羽乌骨母鸡为素材，通过计划选配，育成了公母鸡都为矮脚、黑羽和乌骨性状并能真实遗传的矮小型黑羽乌骨鸡品种群。公鸡胫长６．８±０．５４ｃｍ，母鸡胫长６．１±０．４９ｃｍ，皮乌、肉乌、骨乌，胸腿肌肉发达。开产日龄１７０～１８５ｄ，３００日龄产量５８个，５００日龄产蛋量１３６个。公母比例１∶８～１０，种蛋受精率和受精蛋孵化率可达８５％以上，健雏率９６％以上，６周龄育雏率９２％以上。以其作母系与正常型黑羽乌骨鸡相配，其后代全为正常型，性能优异，种鸡饲养成本明显降低。An experiment taking dwarf dark-feather-and-black-born(DFBB) hens which brought dw gene out of Chishui DFBB chickens as experimental source material and making properly selected mating arrangement was undertaken and a dwarf DFBB chicken variety has been improved.Both cocks and hens of the variety belong to the characters of short leg,dark feather and black born and these characters can be truly hereditable.The tibia length in cocks is 6.80±0.54 cm and that in hens is 6.10±0.49 cm.The skin,muscle and born of the birds all are black and the chest and leg are muscular.The age of started laying period is 170 to 185 days.Its laying performance is 58,136 eggs at the age of 300 and 500 days respectively.The ratio of cocks to hens is 1∶8 to 1∶10.The fertility rate of breeding eggs and hatchability of fertile eggs reached more than 85% and the rate of robust baby birds raeched more than 96%.Brood rate is more than 92% at the age of 6 weeks.Taking the variety as female line to hybridized with formal DFBB chickens all of the F1 are formal phenotype uniformly and belong to superoity performance.The feeding cost of breed chickens is decreased signifcantly.
