A good place to start looking is the Mouse Phenome Database at phenome.jax.org.
From the MPD main page, click on "Phenotype" and browse the blood measures, or click on "Strains" and follow the top links on the next three pages to get to the available phenotypes for C57BL/6 mice.
The best place to look is the one pointed by Dr. Tordoff. Anyway, I add our recent publication with this same strain of mice, where you can find our own results related to metabolic parameters
