Study of some traits on the local population of rabbit in Lebanon in an experimental raising

Hajj E., Boutros C.

In order to identify and to preserve the local population of rabbit, a study has been carried out on some traits of production and reproduction. The experiment was conducted on 20 females and 8 males, randomly distributed between four equal groups of reproduction in order to control crossings. With a semi-intensive rhythm of reproduction (interval of 10 days between the parturition and the next mating), results indicate a very high variability of studied traits qualifying this population as heterogeneous. This heterogeneity could justify a selection program. Receptiveness of females having shown a red color of the vulva was 79 per cent and the rate of gestation 35 per cent. Prolificacy varied from 6 to 7 kits, with 2 to 3 kits at weaning indicating high mortality between birth and weaning (40 to 50 per cent). Pre-weaning growth rate was about 15 plus minus 5 g/d leading to a live weight of 454 plus minus 157 g at weaning. At 77 days of age, the weight was 1.70 plus minus 0.28 kg and the post-weaning live weight gain was about 27 plus minus 5 g/d. The feed conversion ratio between weaning and 77 days of age was 4 plus minus 1.
