“…The improved physical condition and productive performance of F does could be attributed to the obviously increased feed intake (179 g/d of feed) during the flushing period one week before mating; this leads to heavier body weight with good body energy reserves which resulted in heavier litter at birth and higher milk yield, both in turn reflected in heavier kits and litter at weaning (Eiben et al, 2001) with lower pre-weaning death rates. These results are confirmed by those of Tumova et al (2003), who observed that only in the week immediately after restriction, rabbit show a sharp increase for feed intake, to the extent that the daily gain is higher by 40% than the ad libitum fed rabbit.…”

ABSTRACT:A study was conducted to clarify the infl uence of fl ushing or doe relocation as biostimulation methods on oestrus response and subsequent performance on thirty NZW multiparous 10-11-month-old rabbit does after a twomonth resting period in summer. After weaning of their last litter in June, the does were not re-mated and were fed a 100 g daily ration till September, the end of resting period. Then the does were randomly allocated to three groups (10 does/group): a control group (C) in which does remated without oestrus synchronisation, a relocated group (R) and a fl ushed group (F). Relocation consisted of moving does to another room in cages similar to their initial cages 48 h before the intended mating. F does returned to ad libitum feeding one week before mating. After mating, all females were fed and housed under the same conditions. The following parameters were measured: oestrogen level at end of rest period and at mating time, oestrus response parameters, fertility rate, nest quality traits, milk production, litter and kit traits at birth and weaning, and doe weight at mating and kindling. Results obtained revealed that, under the condition of this experiment, fl ushing was superior to relocation as a biostimulation method, since does of F group responded by signifi cantly higher oestrogen level at mating, improved receptivity and fertility rates, higher milk production, and their litters were heavier at birth and weaning. No signifi cant differences were recorded between the different groups for the nest quality traits. On the other hand, doe relocation did not exert any signifi cant effect on oestrus response and subsequent performance of the rabbit does. In conclusion, a short fl ushing period of one week could be good biostimulation method for oestrus synchronisation and improvement of receptivity in multiparous restricted fed rabbit does after a long rest period.

“…According to Eiben et al, (2001) and Rommers et al, (2001), feed restriction during rearing of rabbit, followed by a short flushing and delay of first insemination to an older age, seems to present a promising strategy for optimizing body development of young and improving their productivity and longevity.…”

The objective of the present study to investigate the effect of feed restriction system on growing performance, carcass traits, meat quality and blood parameters of growing New Zealand White (NZW) rabbits, during experimental periods from 5 to 13 weeks of age. A total number of 90 NZW rabbits (male and female ratio 1:1) of weaning aged 5 weeks (about 777.45±10.38g body weight) were randomly divided into five experimental groups (n=18 each), the first group was fed ad-libitum as control, the second group was fed restriction a mount of feed for first 2 weeks only, the third group was fed restriction for 4 weeks only, the fourth group was fed restriction 6 weeks only and the fifth group was fed restriction for all experimental period (8weeks). Results showed a significant (P< 0.01) increased of live body weight, weight gain and feed intake in group 1 (ad libitum) as compared with other restricted groups. No significant effect was observed in health status or mortality percentage of rabbits during experimental periods. Renal fat was significantly (P< 0.05) reduced in rabbits restricted as compared with control group. The meat pH was not affected by restriction feed groups. On the other hand blood parameters studied were not significantly influenced by the treatment. Conclusively, it could be concluded that, feed restriction groups of growing rabbits at different ages studied with various mounts can be adopted because it does not interfere negatively in the performance, meat quality and blood parameters. Also it's beneficial in improvement of feed and economic efficiencies.

Positive effects of restricted and subsequent higher nutrient supply a few days prior to AI on reproduction were found in nulliparous rabbits (Eiben et al, 2001;Gómez et al, 2004;Bonanno et al, 2004a). For multiparous does, an increased pre-mating energy intake could improve conception rate (Fortun-Lamothe, 1998).…”
