摘  要：
试验采用原鸡(♂)与文昌鸡(♀)进行杂交,并对其F1代的外貌特征、体重、体尺等有关指标进行了观察和测定,比较了杂交鸡与文昌鸡的异同,研究了杂交鸡的外貌特征和生长发育的变化规律。结果表明,杂交成年鸡体羽颜色、外貌特征与原鸡基本一致,但杂交成年鸡的体型较大而稍长,胫色、耳叶颜色变浅并发生分离;杂交雏鸡的体重增长比文昌鸡慢,累积生长和绝对生长在第三周差异显著(P<0.05),绝对生长在第四周差异极显著(P<0.01);杂交鸡体尺指标较文昌鸡低,其中体斜长在第三周、第四周差异极显著(P<0.01);龙骨长在第四周差异极显著(P<0.01);胸宽在第三周和第四周也差异显著(P<0.05)。此外,两者除了在胫长和胫围的生长趋势相似外,其他体尺指标的生长趋势都不一样。

摘  要：
In this study, a hybridization was carried out between jungle fowl (Gallus gallus L.)(♂) and domestic Wenchang fowl(♀) and some relevant indexes of F1 such as shape features, body weight, body size etc were observed and determined.Meantime, a comparison was made between hybrid F1 and domestic Wenchang fowl.The shape features and development of F1 were studied.It showed that there was a rough similarity between adult F1 fowl and jungle fowl in feather colour and shape features, except that the adult F1 fowl were bigger and a bit long in body form, with the colour of its shinbone and ear-lobe becoming light, and colour separation coming about.It also showed that the body-weight increase of hybrid F1 chicks was slower than that of domestic Wenchang fowl, and there was a significant difference (P<0.05) between the two in cumulative growth and absolute growth at the third week, and the most significant difference (P<0.01) in absolute growth at the fourth week, and that the indexes of body-size among hybrid fowl were less than those among domestic Wenchang fowl.However, among these indexes there was the most significant difference (P<0.01) between the two in oblique body-length at the third or the fourth week, a significant difference(P<0.01) in sternal length at the fourth week, and also a significant difference in the width of chickenbreast (P<0.05) at the third or the fourth week.In addition, there was a different growth-trend between the two in other body-size indexes, except that a similar growth-trend between the two was observed in shin-bone length and shinbone girth.
