  1. ALP (alkaline phosphatase), CalS (calcified substance), AOS (antioxidase) and SDHG (succinic dehydrogenase). : Data ares non-calcified number of eggs. Compared with ALP: * P < 0.05; ** P < 0.01. All the data were collected from examining 18 blocks of liver or intestinal tissue samples from each of six mice
