Body weight analysis. (A) At P42, all Ur animals were significantly lighter than control animals. In the males, the other HIH animals were also lighter than the controls; however, the comparison between control males and Veh males was not significant. In the females, the Veh animals were significantly lighter than the control animals, but TH and Epo animals were more comparable to the control animals. (B) On the day of HIH (P17), mean (SD) weight of the male kits was 93.0 (7.8) g. On average, HIH males lost 9.6% (7.1%) of their body weight between P17 and P18 as a result of the HIH insult. By P19, HIH males gained 2.0% (6.9%) of their P17 body weight back, compared to a 26.7% (6.0%) weight gain in controls by P19. The HIH males never fully recovered from the weight loss that followed HIH, but the difference in weight between Veh males and control males on P42 lost its significance. (C) At P17, the mean weight of the female kits was 83.3 (5.6) g. On average, HIH females lost 11.3% (8.3%) of their body weight between P17 and P18 as a result of the HIH insult. By P20, HIH females gained 4.4% (13.5%) of their P17 body weight back, compared to a 25.2% (9.0%) weight gain in controls by P20. The HIH females took an extra day longer to gain back the P17 body weight deficit when compared to the HIH males, but the HIH females maintained a weight gain pattern more consistent with the control females by P42. * Denotes p–value < 0.05, ** denotes p–value < 0.01, and ns denotes no significant difference.
