This study was conducted in Shao-ya diaklings,a laying type duck,to determine its abilities of meat production and feed protein utilization before 12 weeks of age.In the grouped feeding trial and nitrogenbalance test,five isoenergetic diets(2950 kcal calculated ME/kg as fed)were used.The crude proteinquality was essentially the same,and their contents were 27.5,23.0,18.4,15.2,and 12.0,respectively.The results were as follows.The growth rate of draklings increased almost linearly during the first 3 we...

用分组饲养试验和代谢试验方法研究用等能量饲粮，不同粗蛋白水平对公绍鸭12周龄前生长和CP利用能力的影响，结果表明：在前3周内日增重随周龄提高近直线上升，5至6周出现高峰；增重与饲粮CP％、CP采食量间，前3周均呈显著正相关(P≤0.05)，以后则在Ⅰ到Ⅳ组范围内呈显著负相关(P.05)，而CP％最低的Ⅴ组不受周龄影响；测得氮存留率为27.4—55.5叻，平均41.5％；公绍鸭生长对CP水平的要求，前3或4周约20—22％，第4—8周15％或略高，其后降至13—14％；公绍鸭养作肉用，在6周龄前后上市可望获利，但此时体重尚轻，到8周龄后，因饲料耗用比过高，只宜进行牧饲或散养。

To search for DNA-based sex identification candidate marker of poultry, whole blood DNAs from each five males and five females of Native Chicken, Brown Tsaiya, Muscovy, White Roman Goose, Bronze Turkey, Australian Black Swan, Quail and Ring-necked Pheasant were analyzed by spindlin gene. PCR products were amplified by SPIN12 and SPIN13 primer kits. Different electrophoresis patterns showed correct gender for each bird species. The accuracy of sex identification was 100%. Furthermore, the PCR DNA fragments of the same gender were different among bird species.

以土鸡、褐色菜鸭、番鸭、白罗曼鹅、青铜火鸡、澳洲黑天鹅、鹌鹑、环颈雉各5公5母个体 DNA作为模版，应用SPIN12及SPIN13引子组进行聚合酶连锁反应后，由电泳分析结果显示所有受检物种之雄性与雌性均呈现不同样态，且与实际性别吻合，证实此引子组可成功鉴别鸡、鸭、番鸭、鹅、火鸡之性别外，亦可作为黑天鹅、鹌鹑、环颈雉等鸟类的性别遗传标记，从不同物种所呈现的DNA片段亦有变异存在。
