| 摘 要： | 用北京油鸡与红宝鸡进行正反杂交，并与红宝、北京油鸡进行比较观察，测定其后代生长速率、饲料报酬。结果表明，红宝与北京油鸡杂交可明显提高北京油鸡杂交后代的生长速度和饲料报酬。试验还表明，在生长速率上，红宝鸡的母本效应明显，北京油鸡作父本应用比用作母本效果好，周增重速率从第３周时就表现出快速趋势

| Abstract: | Reciprocal crosses were conducted in Beijing Fatty chicken and Redbro chicken.Growth rate and food conversion effiency(FCE)were compared in Beijing Fatty chicken,Redbro chicken and their reciprocal hybrids.The comparative results indicated growth rate and FCE were higher for reciprocal hybrids than for Beijing Fatty chicken. Because reciprocal effect on growth rate was obvious,it was suggested that Redbro chicken should be used as maternal line and Beijing Fatty chicken as paternal line when crossing. |
