Notes: No statistically significant difference in age was observed between shelter-breeding group and temporary groups or between corral-breeding groups and shelter-breeding groups. There was a statistically significant difference in age between animals in corral-breeding groups and those in temporary groups (One-way ANOVA: F = 3.31, df = 2, P = 0.04). Among all animals, there was a statistically significant difference in age between males and females (two sample t-test: t = 14.51, Satterthwaite adjusted df = 3,179, P < 0.01).
