Nutritive value of fresh sulla (Hedysarum flexuosum) as a sole feed for growing rabbits

Abstract : For determining the nutritive value of Sulla (Hedysarum flexuosum), containing organic matter (OM) 84.3; crude protein (CP) 22.5; neutral detergent fibre (NDF) 49.0; acid detergent fibre (ADF) 34.3; acid detergent lignin (ADL) 10.8 % on DM basis, sixteen rabbits of Algerian white local population (individually caged) weaned at 35d old (mean body weight: 541±29g) were fedad libitum fresh green Sulla as a sole feed during five weeks. The faecal digestibility of the Sulla was measured between 49 and 53 days of age on 12 rabbits. The digestibility of DM, OM, CP, NDF and ADF was 52.3; 52; 64.4; 35.5 and 28%, respectively. The average DM intake reached 114.2 g/d (125.6 g/kg LW 0.75), while the digestible CP intake was 17.7g/d (19.5 g/kg LW 0.75 d) and that of digestible energy (DE) was 1.05 MJ/d (1.15 MJ/kg LW 0.75). These digestible nutrients intake allowed to meet not only the maintenance requirement, but also to support a growth rate of 18.9 g/d. The digestible energy concentration of the fresh Sulla was 9.2±0.15 MJ/kg DM, while the digestible crude protein concentration was 145±1.8g/kg DM. Harvested at young stage of growth, Sulla could be considered as a good and balanced fibre source for the growing rabbit and comparable to other good quality forages such as alfalfa and ryegrass.
