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