Abstract

Postweaning development was monitored in domesticated rabbits reared in single- or mixed-sex groups at a commercial farm. The results suggest that sex composition of cage groups had no significant effect on weight gain, feed intake or mortality rates from weaning (35 days) to marketing (93 days). On sacrifice at 93 days, females from single- and mixed-sex groups showed no significant differences in plasma gonadotropin levels (LH and FSH) or weights of paunched carcase, ovaries, uterus, adrenals, kidneys or kidney fat. Evidence for within-cage dominance hierarchies was found at 63 days of age when 46% of the rabbits inspected showed signs of aggressive attack.
