摘要
蛋雏鸡采用玉米 豆饼日粮 ,添加过量镁 (MgO) ,结果胫骨中镁含量增加 ,钙的含量降低 ,胫骨中钙 镁、磷 镁、钙 磷的比值减小 ,X光摄影 ,骨质疏松。电子显微镜检验 ,骨组织增生。机械力学法检测其鲜骨的最大抗压能力 。
Laying chicks fed corn-Soybean bean rations supplemented with toxic level of magnesium. The results showed that magnesium content in tibia was increasea.Tibia calcium to phosphorus mass ratios\, calcium to magnesium mass ratios and phosphorus to maqnesium mass ratios were decreased. The bone tissue was loose. New bone tissue was hyperplasia. The compressive strength of tibia came down.
