The aim of this study was to determine the effect of pelleted cerealbased feed in the diet for addax antelope (Addax nasomaculatus) on feed intake and nutrient digestibility. Four addax females (3 years old) were allocated to 1 of 3 treatments according to 3 × 3 Latin square design and fed 3 diets. Each diet consisted of basal diet and meadow hay. In diet A basal diet consisted of a mixture of ground concentrates, chopped dehydrated lucerne, vegetables and fruits. In diet B 50% and in diet C 100% of dry matter (DM) provided with concentrates and chopped dehydrated lucerne in diet A was replaced with a pelleted cereal-based feed. Meadow hay was offered ad libitum. Two females (sisters) were kept together through the study and thus pen was used as an experimental unit. The diets were formulated to be similar for crude protein and crude fibre content. DM intake (DMI) of basal diet did not differ between treatments (P ≥ 0.52) whereas DMI of hay and total DMI linearly decreased with increasing pellet inclusion in the basal diet (P = 0.05 and P = 0.03, respectively). Digestibility of neutral detergent fibre tended to linearly decrease (P = 0.09) and digestibility of hemicellulose linearly decreased (P = 0.05) with increasing pellet inclusion in the diet. Pelleted cereal-based feed used in the diet for addax had a negative effect on roughage intake and digestibility of structured carbohydrates compared to non-pelleted feed of similar nutrient composition.
