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。

Firstly, achieving a new low and high cycle noninterfering loading, the high frequency induction local heating, the control of high cycle vibration frequency and amplitude, and the crack propagation real-time detection, an experimental system of L-HCCF at elevated temperature is established. Secondly, under two vibration frequency (50Hz and 100Hz), the contrast experiment of light and serious corrosion disc slots is done. It is found that the experimental L-HCCF life of serious corrosion disc is less than that of light's, but its dispersion is larger, and the experimental failure is identical with the service's.
