摘要
测定了鸡、乌鸡、鹌鹑及其属间杂交种的早期生长性状,根据各类禽在0～10周龄的体重、平均日增重及相对生长参数,分别绘制出累积、绝对和相对生长速度曲线。分析了杂交禽与其父母本早期生长性能的差异及趋势。结果表明:杂交禽成年后体重为480～500g,约为鹌鹑的3倍;杂交禽1～2周龄相对生长率最大,5～6周龄绝对生长达到高峰,至10周龄时,两者均有明显降低;其迅速生长期比鹌鹑延长了3周,表明属间杂交使得杂交禽子一代同时获得了两亲本的优良性状,既具有父本快速生长的特征,又具有母本早熟的遗传特性。
The early growth performance of chicken(♂),silkies (♂),quail (♀)and chickenquail hybrids were measured. According to 0～10 wee k weights in various poultry,drawn accumulation,absolute and relative g rowth curve. The difference and trend were analyzed between the chickenquail h ybrids and its parents in early growth performance. The results showed that the adult chickenquail hybrid weights were about 480～500 g,it is three times as m ore as the adult quail weights; The relative growth rate are the biggest of the hybrids in 1～2 weeks, reach to the peak of the absolute growth rate in 5～6 wee ks, Their weights declined significantly for both the hybrids and quail when th eir weights reach 10 weeks; The hybrids extend three weeks than quail in rapi d growth stage. The hybrids have combined with the character of its parents at s uperior growth performance. Hybridization possessed the hybrids with its father character of rapid growth and its mother genetic character of precocity.
