摘  要：
将648只罗曼商品代产蛋鸡随机组群进行九种处理(3×3因子试验)来确定三种不同含钙量日粮(2.75％、3.75％和4.25％)和三种不同含磷量日粮(?)和(?)50％)对产蛋高峰期中产蛋鸡产蛋性能、胫骨重、胫骨强度、胫骨灰分等的影响。当日粮中磷钙水平增加时对饲料消耗量也随之增加:增加日粮中钙含量时,蛋的比重也随之呈线性增高;(?)增加日粮磷含量时对蛋的比重无影响。日粮中钙磷水平对鸡的产蛋率、体重无显著影响。随着日粮中钙含量增加,鸡的胫骨强度、胫骨重则对这些指标无明显影响。然而当日粮中(?)水平为2.75％时,降低日粮中磷的含量将会明显地影响胫骨强度,胫骨重、胫骨灰分的质量。

摘  要：
Six hundred and forty-eight Roman (F1) Puiletswere randomly allocated 'o nine treatments and arranged in a 3×3 factorial to determine the effects of three levels of di-etary calcium (2. 75. 3. 75 and 4. 25%) and three levels of dietary available phosphorous (0. 30, 0. 40 and0. 50% ) on eggshell quality and tibia weight,tibia breaking strength, tibia ash of pullets during peak production. food consumption increased as dietary calcium or phospho rousincreased. Increasing dietary calcium aroused a slight significant increase in egg specific gravity , but dietery phosphorous had no significant effect on egg specific gravity. Calcium and peospuorous levels did not significantly effectegg puoction , body weight or phospho-rous. Ionized calcium incressed significantly as dietary calcium increased. yibia breading strength. tibia weight, tibia asd increasedsignificanrly with increasing dietary calcium. Di-etary phosPhorous had no significant effect on these parameters. However,where 2. 75% cal-cium was fed, reducing dietary phosphorous significantly decreased tibia weight and tibia ashcontent.
