| 摘 要： | 试验对樱桃谷SM3父母代种鸭一年的入孵种蛋数、受精蛋数、出雏数进行了跟踪观测.并对种蛋受精率(x)与受精蛋孵化率(y)之间的相关与回归关系进行了分析,建立了相应的回归方程.结果表明,在孵化技术水平和孵化条件相对稳定时,种蛋受精率与受精蛋孵化率呈显著的正相关关系,可得到如下回归方程:y=0.433x+57.735;应用该回归方程可以指导生产实践、制定科学饲养管理和孵化新技术,并可望大幅度提高饲养效益.

| Abstract: | The yearly amount of incubative breeding eggs, fertilized breeding eggs and hatching rate of fertilized eggs of cherry valley breeding ducks (Super M3) were analyzed in this experiment. The correlation between fertilization rate of breeding eggs (x) and hatching rate of fertilized eggs (y) was analyzed and the regression equation was obtained. Under the relatively stable conditions of incubation, the fertilized rate of breeding eggs and hatching rate of fertilized eggs had significant positive correlation. ... |
