Based on colony records, the mean body masses of all adult, non-pregnant animals in the WNPRC (438 ± 5 g), and SNPRC (456 ± 7 g) colonies, and the animals maintained on the NEPRC diet but housed at SNPRC (441 ± 7 g) were not significantly different, though the difference between SNPRC and WNPRC approached significance (p = 0.065).
