Aspects of sex breeding and segregation in rabbits

Abstract

This research study presents some indices of reproductive and sexual heredity in rabbits. The investigation subject was a rabbit flock that had the same raising conditions and the same experimental period. The largest prolificacy was obtained in October (7.6 animals) and August (7.55 heads); the lowest prolificacy was recorded in the winter months, and namely in December (5.8 heads), January (6.05 heads) and February (6.8 heads). This proves the doe-rabbits’ dependence on the day length and influence on the reproduction. The closest gender segregation ratio is 1: 0.9 in July and the farthest one is 1:1.5 in December in favor of males, which are born more often than females.
