| Popis: | This research study presents some indices of reproduction 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 prolificity was obtained in October (7.6 animals) and August (7.55 heads); the lowest prolificity was recorded in the winter months, and namely in December (5.8 heads), January (6.05 heads) and February (6.8 heads). This proves that reproduction function in rabbit does depends on day length. 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. |
