“…Moreover, some of these plants contain antinutritional secondary compounds (phenolics, tannins) with potential adverse effects such as inhibition of rumen microbial fermentation, as well as decreased feed digestibility and animal performance (Min et al, 2003;Waghorn & McNabb, 2003;Mueller-Harvey, 2006). In spite of their limited nutritional value, these forage resources are indispensable as feeds for herbivores when production systems are based on grazing rangelands (Papanastasis et al, 2008).…”

Many wild browse and bush species are undervalued mainly because of insufficient knowledge about their potential feeding value. The objective was to evaluate some nutritional attributes of various Algerian browse and shub species (Atriplex halimus, Artemisia campestris, Artemisia herba-alba, Astragalus gombiformis, Calobota saharae, Retama raetam, Stipagrostis pungens, Lygeum spartum and Stipa tenacissima). Chemical composition, phenols and tannins concentration, in vitro digestibility, in vitro gas production kinetics and in vitro bio-assay for assessment of tannins using buffered rumen fluid, and in situ disappearence of the edible parts of the plants (leaves, thin twigs and flowers) were determined. In general, protein content in dicotyledon species was always greater than in monocotyledon grasses, these showing higher neutral and acid detergent fibre and lower lignin contents than dicots. The tannin concentrations varied considerably between species, but in general the plants investigated in this study had low tannin contents (except for Artemisia spp. and S. tenacissima). Monocots showed lower in vitro and in situ digestibilities, fermentation rate, cumulative gas production and extent of degradation than dicot species. The plants were clustered by principal components analysis in two groups: poor-quality grasses and the most digestible dicot species. Chemical composition (neutral detergent fibre and protein) and digestibility were the main influential variables determining the ranking. In conclusion, A. halimus, A. campestris, A. herba-alba and A. gombiformis can be considered of greater nutritional value than the highly fibrous and low digestible grasses (S. pungens, L. spartum and S. tenacissima) that should be considered emergency roughages.

“…Low organic matter digestibilities for Mediterranean browse species (0.50 to 0.55 measured in vitro) are reported and explained by the high content in secondary compounds such as tannins (Papanastasis et al, 2008). Tannins are a group of substances (comprising hydrolysable and condensed forms) that bind to proteins in the rumen and can have either positive or negative effects on intake and digestion depending on the animal species and experience, the proportion in the diet and the absorption of feed additives (for a comprehensive review, see Makkar, 2003).…”

“…While interesting classifications based on functional approaches of grass species have been proposed for grasslands , little has been done to our knowledge for shrubland and woodland communities. The main Mediterranean shrubland communities are maquis (dense shrub communities on siliceous soils), garrigue (open shrub communities on calcareous soils) and phrygana (open, dwarf shrub communities on friable soils); the main woodland communities are dense coniferous woodlands, dense broadleaved woodlands and sparse silvopastoral woodlands (Papanastasis et al, 2008). Vegetation diversity in rangeland is supported by physical, biotic and human factors.…”

“…Papanastasis et al (2008) report that shrublands are more productive than grasslands in similar conditions and that their forage production depends mainly on shrub density and height. Shrubs contribute to the total forage production, but limit the production of the herbaceous layer.…”

“…Shrubs contribute to the total forage production, but limit the production of the herbaceous layer. Herbaceous and woody species not only differ in the amount and quality of biomass production, but also most interestingly in the period when they are available for grazing: winter and spring for herbaceous species, summer and autumn for shrubs and trees (Papanastasis et al, 2008).…”

In the countries surrounding the Mediterranean basin, most of the semi-natural grazing lands are covered by rangelands. Rangelands can be defined as highly heterogeneous natural vegetation communities with high conservation value, growing in harsh environments (poor soils, unfavourable climatic conditions). In the recent socio-economic context, traditional livestock grazing practices that enabled one to reconcile rangeland preservation and animal production no longer apply, especially because they require labour that has become scarce and costly. The consequence is rangeland degradation, due to underutilization in Southern Europe, and overutilization in Northern Africa. We analysed issues raised by rangeland utilization in livestock farming systems of the Mediterranean basin. Based on a review of the scientific literature about rangeland utilization in this area, we argue that the best way to reconcile animal production and rangeland preservation would be to promote management practices allowing animals to express their adaptative capacities in feeding behaviour and productive response. In order to propose management practices adapted to extensive and simplified systems, we conclude that research efforts should focus on: (i) proposing a functional characterization of vegetation heterogeneity at the scale of the vegetation community, (ii) validating the criteria determining animals' foraging behaviour on Mediterranean rangelands, (iii) developing and using simulation models to test management strategies against seasonal and long-term variability in climatic conditions and (iv) evaluating the potential of modern technologies for improving rangeland utilization.
