Figure 4.

Consumption of timothy hay and food pellets during the observation period. Points depict the mean percentage of total time that Hartley (HR) and Hairless (IAF) animals spent consuming either (A) timothy hay from the rack in the open field or (B) food pellets in the home cage during each of the four 15-min segments (segments 1 through 4). Bonferroni-corrected significant differences were revealed between open field and home cage consumption (P < 0.001) during segments 1 through 3 by both strains. In addition, Hairless subjects showed increased time spent consuming hay during the 4th segment for the open field relative to home cage (P = 0.006). In the open field, values for Hairless subjects were increased significantly (P < 0.006) relative to Hartley during all but the third segment. Error bars represent the SEM.
