Effect of Dietary Insoluble and Soluble Fibre on Growth Performance, Digestibility, and Nitrogen, Energy, and Mineral Retention Efficiency in Growing Rabbits

摘要: Dietary soluble fibre limits the incidence of epizootic rabbit enteropathy (ERE) and improves energy nitrogen balance in low-insoluble diets, while high-insoluble diets seem to favour ERE. This study assessed whether positive effects are influenced by level insoluble fibre. Four (2 × 2 factorial arrangement) were used with two levels (314 vs. 393 g/kg DM) (87 128 DM), resulting four increasing total dietary levels. Growth performance chemical composition (body carcass) (28-62 days age), faecal digestibility (54-57 jejunal morphometry functionality (39 age) determined. Mortality was low (<1%) treatments did not influence it. Insoluble tended reduce growth rate (p ≤ 0.109), body protein, fat accretion = 0.049 0.120), but only impaired feed efficiency < 0.001). The digestible for increase 0.027), that remained majorly unaffected. In conclusion, healthy rabbits, either or had no benefit.
