The present study was designed to evaluate the effects of dietary flavophospholipol ("Bambermycin") levels on the growth performance in 400 hybrid rabbits from weaning at 28 days until slaughter at 74 days of age. The fryers were randomly assigned to one of the four dietary treatments that consisted of either 0, 4, 8 or 16 ppm supplemental flavophospholipol. Each treatment was applied to 100 animals each. Dietary treatments exerted no significant effects on live weight, daily weight gain and feed consumption across the entire fattening period. However, daily weight gains in treated fryers were increased by 2.4% on the average. The only significant treatment effect was found in feed conversion (food/gain) in fryers fed 16 ppm supplementation; kilogram food intake per kilogram weight gain was reduced by 0.16 kg as compared to the control group. Mean feed conversion in treated groups was improved by 3.5% on the average. In addition of flavophospholipol a significantly decreased mortality was observed. It was remarkable, that losses caused by infection in control were exclusively due to infections by Bordetella species, while the treated groups were only caused by Pasteurella species.
