| 摘 要： | 试验选用25周龄罗曼褐父母代蛋种鸡720只,随机分为4个组,试验组分别在空白对照组饲粮基础上添加0.05%土霉素、0.1%和0.2%的复合益生菌制剂,以比较其效果。试验结果表明:在饲料中添加复合益生菌能显著提高种鸡的产蛋率和营养物质表观利用率,降低饲料报酬,对种蛋孵化率没有不利影响。 |
| 关 键 词： | 复合益生菌 产蛋率 孵化率 营养物质表观利用率 |

| Abstract: | A total of 720 Lohman brown parent-breeding layers were randomly divided into 4 dietary treatments .The basal diet were supplemented 0.05% terramycin,0.1% and 0.2% compound probiotics,respectively. The results indicated that dietary supplementation with compound probiotics significantly improved laying rate and nutrient digestibility,and decrease feed remuneration,whereas there were no significant difference for the hatchability of breeding eggs among all groups. |
| Keywords: | compound probiotics laying rate hatchability nutrient digestibility |
