摘　　要：本文以18周龄农凤鸡和青脚白羽鸡(各10只)为试验材料,比较矮小型和正常型鸡体型性状和内脏器官发育的差异。结果表明:矮小型鸡比正常型鸡体重低41%,背高低29%,身长短18%,肩宽窄15%,胫长短21%,骨盆窄14%;矮小型鸡的心脏、肺脏、脾脏和各消化器官的绝对重量均低于正常型鸡,但肺脏、脾脏、腺胃和食道、肌胃、十二指肠的相对重量大于正常型鸡;矮小型鸡各消化器官的绝对长度均小于正常型鸡,但肌胃和十二指肠的相对长度大于正常型鸡;矮小型鸡的消化系统较发达,屠宰率低于正常型鸡。The paper compared the differences of body development between dwarf chicken and ordinary chicken. Ten , type traits and internal organ＇s ＂Nongfeng＂ hens, ten hens with cyan claws and white wings as test materials, these hens both at 18-weeks-old. Results showed that dwarf chicken were 41%, 29%, 18%, 15%, 21%, 14% lower/shorter in weight, back height, body length, shoulder width, shank length and pelvis width respectively. The absolute weight of heart, lung, spleen and other alimentary organs of dwarf chicken we.re all lower than that of ordinary chicken. However, the relative weight ,of lung, spleen, stomach gland and esophagus, gizzard, duodenum of dwarf chicken all higher than that of ordinary chicken. In terms of absolute length, all the alimentary organs from dwarf chicken were shorter than that of ordi- nary chicken, while gizzard and duodenum were longer than that of ordinary chicken when com- pared on~ the relative length. Furthermore, dwarf chicken had relative stronger alimentary system, but the slaughter percentage of dwarf chicken was lower than that of ordinary chicken.
