| An experiment was conducted in a farm affected by Epizootic Rabbit Enteropathy to investigate the effects of dietary fibre content and weaning age on Cl. perfringens proliferation in the gut and fattening mortality in growing rabbits. The experiment consisted in a 2 x 2 factorial arrangement with two weaning ages (28 vs. 42 days) and two levels of dietary neutral detergent fibre assayed with a heat stable amylase and expressed exclusive of residual ash (aNDFom; 330 vs. 425 g/kg). Controls were made during two consecutive experimental periods that differed in hygienic environmental conditions by modifying the intensity of cleaning and disinfection in the farm previous to the trial. An interaction (P < 0.001) was detected among the independent variables studied on Cl. perfringens enumeration in the caecal contents, as minimal values for this trait were obtained in non-medicated animals reared in a clean environment, and especially when they were weaned at a later age and fed the diet with the lower fibre content. The treatments studied also led to a variation in fattening mortality (from 4.7 to 34.0%), which was highly and positively correlated (P < 0.001) to the average Cl. perfringens caecal counts in each combination of treatments. The results of the current study indicate that high counts of Cl. perfringens in the gut can be used as an indicator of Epizootic Rabbit Enteropathy, and suggest that strategies designed to control its proliferation in the gut might help to limit fattening mortality in rabbit fed diets not-medicated with antibiotics. | |
