Nutritive value of fresh ash (Fraxinus Angustifolia) leaves for growing rabbits
Résumé
The nutritive value of Ash (Fraxinus angustifolia) leaves, harvested in autumn was determined (direct method), using ten rabbits (individually caged) weaned at 35d old (mean body weight: 911g) fed ad libitum only fresh Ash leaves during 16 days. Ash leaves composition was: organic matter (OM) 89.3%, crude protein (CP) 14.6%, neutral detergent fibre (NDF) 39.4, acid detergent fibre (ADF) 26.3, acid detergent lignin (ADL) 15.1% on dry matter (DM) basis. The faecal digestibility of the Ash
leaves was measured between 48 and 51 days old. The digestibility of OM, CP, NDF and ADF were 74, 67, 59 and 59% respectively. The concentration in digestible energy and digestible protein of the Ash leaves was estimated to 13.59 ± 0.90 MJ and 98 ± 10.4 g/kg DM respectively. The Ash leaves harvested in autumn could be considered as a good source of energy and fibre for growing rabbit. Key words: Ash leaves, Fraxinus angustifolia, nutritive value, autumn, digestibility
