摘  要：
为了研究 0～ 6周龄蛋雏鸡适宜钙需要量 ,试验设计了不同日粮钙水平 (0 .7,0 .8,0 .9,1.0 ,1.1,1.2 % )对该阶段蛋雏鸡的生长性能、骨骼质量和血清有关指标的影响。结果表明 ,在 0～ 6周龄期间 ,钙水平为 0 .9%和 1.0 %的处理组全程增重最大 ,分别为 4 4 6 .4 4± 39.2 2 g和4 55.96± 39.4 9g ,两者间差异不显著。 1.0 %处理组增重显著高于其它 4组 (P <0 .0 5) ;0 .9%的处理组增重显著高于 1.1%和 1.2 %处理组 (P <0 .0 5) ,和 0 .7%和 0 .8%处理组相比尽管差异不明显 ,但也表现出较优的增重性能。 0 .7%和 0 .8%的处理组增重明显优于 1.1%和 1.2 %处理组(P <0 .0 5)。料重比也表现出类似的规律 ,即 0 .9%～ 1.0 %处理组最低 ,0 .7%～ 0 .8%其次 ,1.1%～ 1.2 %最高。从统计学角度考察 ,骨钙、骨磷和血清钙、磷在各处理组并无明显差异 ,粪钙检测结果表明排出体外的粪钙量随钙水平的升高而增加。上述结果说明 0～ 6周龄蛋雏鸡日粮中钙的适宜水平应为 0 .9%～ 1.0 %。

摘  要：
The effects of different dietary Ca levels (0.7, 0.8, 0.9,1.0, 1.1 and 1.2%) on performance, tibia quality and serum characteristics of 0～6 week old pullets were studied to determine the optimum calcium requirement. The results showed that among six groups tested, the groups of pullets fed at dietary calcium level of 0.9% and 1.0% reached the highest body weight gains (BWGs) of 446.44±39.22g and 455.96±39.49g, respectively, which were not significantly different. The BWG of 1.0% dietary Ca level group was significantly higher as compared with the groups of 0.7%, 0.8%, 1.1% and 1.2% dietary Ca levels ( P < 0.05). The BWG of 0.9% level group was significantly higher as compared with the groups of 1.1% and 1.2% dietary Ca levels ( P < 0.05), and not significantly higher as compared with the groups of 0.7% and 0.8% dietary Ca levels ( P < 0.05). The BWGs of the groups of 0.7% and 0.8% dietary Ca levels were higher than those of the groups of 1.1% and 1.2% dietary Ca levels. The feed/gain ratios varied in a similar way to BWG, those of the groups of 0.9% and 1.0% dietary Ca levels were lowest, those of the groups of 0.7% and 0.8%dietary Ca levels were medium and those of the groups of 1.1% and 1.2% dietary Ca levels were highest. There were no obvious differences in calcium and phosphorus concentrations in bone and serum among the six groups. The fecal calcium excreted rose with the increase of dietary calcium level. It is clear based on these experiment results that 0.9% and 1.0% dietary Ca levels are optimum for 0～6 week old pullets.
