| 摘 要： | 蛋鸡饲粮中添加300mg/kg、400mg/kg的有机稀土络合物，观察其对蛋鸡产蛋率、平均蛋重、采食量等的影响。结果表明：添加稀土能显著提高产蛋率，两试验组分别比对照组高出3.54和6.18个百分点；而对蛋重、采食量影响不大。

| Abstract: | Added 300 mg/kg, 400 mg/kg organic rare - earth to the feed of layers and observed the influences to laying rate, average egg sire and feed intake. The results showed that the organic rare - earth could improve the laying rate. The two experiments were 3. 45% and 6. 18% higher than the control group. The rare - earth had little influence to eggsire and feed intake. |
