A high Ca, semi-purified diet promoted greater egg production with thicker shells in Japanese quail hens. 7 ppm of dietary Se depressed egg weights with no effect on eggshell thickness. The addition of 20 ppm of MHg to either a low or high Ca diet containing Se depressed both egg production and eggshell thickness. Se residues of liver, kidney, and brain in Se-MHg fed quail were significantly higher than in Se treated quail, probably reflecting the ability of Se to bind with Hg. CA, an enzyme required for the formation of the carbonate radical of Ca carbonate in eggshells, was not reduced in the Se-MHg treated Japanese quail hens' blood or oviducts.
高钙半纯化日粮可提高日本鹌鹑母鸡的产蛋量，且蛋壳更厚。日粮中7 ppm的硒会降低蛋重，但对蛋壳厚度没有影响。在含硒的低钙或高钙日粮中添加20 ppm的甲基汞会降低产蛋量和蛋壳厚度。饲喂硒-甲基汞的鹌鹑肝脏、肾脏和大脑中的硒残留量显著高于饲喂硒的鹌鹑，这可能反映了硒与汞结合的能力。碳酸酐酶（CA）是蛋壳中碳酸钙碳酸根形成所需的一种酶，在经硒-甲基汞处理的日本鹌鹑母鸡的血液或输卵管中并未减少。
