摘要
试验采用玉米-豆饼型试验日粮，高镁组（6000×10-6，MgO）鸡血液中镁含量显著高于中镁组（1200×10-6，MgO）和对照组（0．00×10-6，MgO）（P＜0．05），中镁组与对照组间无显著差异（P＞0．05），而血液中其他矿物元素含量三组间无显著差异（P＞0．05）。在肝脏中，高镁组的磷沉积量显著低于中镜组和对照组（P＜0.05），而中镁组与对照组间无显著差异（P＞0．05），其他矿物元素沉积量三组间无显著差异（P＞0.05）。在脾脏、肾脏、胰脏中镁、其他矿物元素的含量及沉积量三组间无显著差异（P＞0.05）。肝脏、脾脏、肾脏、胰脏的鲜重三组间无显著差异（P＞0．05）。
The effect of magnesium level (1. Control group 0.00× 10-6 Mg2+, C; 2. Medium magne-sium group 1200× 10-6 Mg2+, M; 3. High magnesium group 6000×10-6, H) on layer - grower wasstudied with conventional diet supplemented with MgO. The results showed that magnesium content inblood was higher in H group than that in C and M groups (P < 0.05) with no significant differences (P> 0.05) . Other mineral content in bloodr had no significant differences in C, M and H groups (P >0.05). Phosphorus depesition in liver in H group was higher than that in C and M groups (P < 0.05)with no significant differences (P > 0.05). Otder mineral dpeition in liver has no significant differencesin C, M and H groups (P > 0.05). Magnesitim and other mineral in spleen, kidney and pancreas haveno significant differences in C, M and H groups (P > 0.05) . The effect of magnesium level on gaid inweight of liver, spleen, kidney and pancreas were not significantly differente in C, M and H grpups (P> 0. 05).
