繁殖小白鼠食崽现象与食饵性补钙关系的研究

The Study on Relationship Between Youngeating and Calcium Addition in Stock Mice

目的:观察繁殖小白鼠食崽现象与食饵性补钙的关系。方法:以BALA/c小白鼠和FVB小白鼠为实验动物,在饮用水中添加微量元素钙作添加剂,对繁殖鼠进行了长期的饲养观察实验。结果:繁殖母鼠通过食饵性补钙,食崽现象得到有效遏止。实验数据显示:当繁殖鼠体内血清钙浓度降低到(2.30±0.05)mmol/L时,出现食崽现象;当血清钙浓度达到(2.51±0.08)mmol/L时,无食崽现象,繁殖正常。结论:缺钙是母鼠食崽的主要原因,通过食饵性补充钙,可有效预防母鼠食崽。

To solve the problem of youngeating arising in the stock mice after giving birth to several litters,we fed the stock mice with the calium gluconate as a additive.The youngeating was completely suppressed in positive mice fed with calcium gluconate.Calcium serum content of the preganant mice fed with common food was(2.30±0.05) mmol/L,going with the occurance of youngeating.In contrast with the control,calcium serum content of positive preganant mice was(2.51±0.08) mmol/L above.Thus,application of the calcium...
