Abstract
- Four groups, each consisting of 684 weaned (35 days) hybrid Hyla rabbits were fed ad libitum the same commercial concentrate supplemented, respectively, with antibiotics (AGP group: colistin sulphate 144 mg/kg; tylosin 100m g/kg and oxytetracyclin 1000 mg/kg) or with mannan oligosac- charides (MOS) at 0.5 (group MOS_0.5), 1.0 (group MOS_1.0) and 1.5 g/kg (group MOS_1.5). Up to 60 days, mortality rate was recorded daily. For each group, 64 rabbits were controlled weekly for live weight to calculate daily weight gain (DWG). Feed intake (and, by consequence, feed conversion ratio) was measured, weekly, per group. No differences were observed for live weight during the trial, while DWG showed an alternate trend, in general, significantly lower for AGP group, exclusive of the third week (49- 56 days). Exclusive of the first week of the trial feed intake was higher for AGP than the other groups and the feed conversion ratio was more favourable for MOS groups. Mortality rate was significantly higher (34.2%) in AGP groups. The lowest mortality was recorded in MOS_1.0 group (7.75%).
