Abstract
Degradation aspects in terms of kinetics of the tested samples namely  dates, oranges and olive residues by the dromedary ruminal microflora is comparatively studied with vetch-oat hay as a standard. The results indicate greater hydrolytic ac-tivity of the dromedary ruminal microflora towards dates and orange residues than both olive residues and hay.  Fermentation of dates and orange residues reaches their stationary phase after 24 hours and olive wastes after 48 hours. However, fermentation process was marked by two phase; namely the degradation of soluble fraction and that of cellulosic one. The results showed also that types of substrate is a determining factor for in vitro gas production. In fact, substrate rich in cellular content (dates and orange residues) is characterised by a fast fermentation that moves towards CO2 production, and it is marked by a long latency phase. On contrary,  the fibrous substrate degradation (olive residues and hay) is tributary of less long latency period and generates CH4. The degradation level observed indicates that the dates and oranges residues might represent an acceptable source of energy for dromedary. On the other hand, the olive residues, in spite of being rich in organic matter, cannot be used in animal feeding.
