在生物实验中,饲料是主要的,但常常忽视了它的变化。在毒理和生物医学实验中,使用半合成饲料有很多好处。在必需营养成份未弄清前,饲喂半合成饲料更加重要,但是常发生肾钙质沉着病,尤其是饲喂的雌大鼠。这样严重地干扰了实验。这个实验目的为了研究半合成饲料中矿物质成份、 In biological experiments, feed is the main, but often overlooked its changes. There are many benefits to using semi-synthetic feed in toxicological and biomedical experiments. Feeding semisynthetic feed was even more important before essential nutrients were elucidated, but nephrocalcinosis often occurred, especially in fed female rats. This severely interfered with the experiment. The purpose of this experiment in order to study the semi-synthetic feed mineral composition,
