摘 要: | 本试验比较了部分添加粗石粉与全部用细石粉的饲料对高龄蛋鸡生产性能的影响。结果表明,高龄蛋鸡部分使用颗粒状石粉组比全细石粉组饲料耗减少13.09%(P〈0.01),对其他产蛋指标没有显著影响;试验组有机物质和磷的利用率比对照组高2.87%和26.85%(P〈0.05),对其他营养物质的代谢率没有显著影响。

EFFECT OF PART GRANULEAR CALCIUM SOURCE ON OLDER HEN |
| |
Abstract: | Twenty four hens were utilized in two treatments with 30-d periods to determine effects of different calcium on intake,egg production,weight and nutrient digestibilities. Treatment 1 was 4% limestone plus 3.7% stone grain, treatment 2 was only limestone. Treatment 1 decreased intake significantly, tended to increase egg production, and significantly increased apparent digestibilities of organic material and P. |

Keywords: | older hen: limestone performance digestibility |
