^a,bMeans with differing superscripts indicate a significant (P < 0.05) difference.

¹Initial composition was determined by dual x-ray absorptiometry (DXA) scan 3 d prior to inoculation. Final composition was determined by DXA scan at 42 dpi. Whole body accretion was calculated by (corrected final composition– corrected initial composition)/d on test.

²BMC = bone mineral content.

³BMD = bone mineral density.
