“…For all the browse species, except for A. asak, the ADF fraction was a large proportion of the NDF, which indicated high content of cellulose and lignin and low hemicellulose content. The CP and cell wall fibre contents reported for A. tortilis, A. amara, D. cinerea, B. aegyptiaca and Z. spinachristi in this study were similar to those reported in other studies (Heneidy 1996;Shayo and Uden 1999). Browse species with relatively high content of condensed tannins such as A. amara, A. asak and S. africana may have limited intake by browsing animals since low preference was associated with high condensed tannin content of browses (Kaitho et al 1997).…”

The study was conducted in Abergelle district of Tigray, northern Ethiopia with the objectives of evaluating the chemical composition, in vitro dry matter digestibility (IVDMD) and in sacco degradability characteristics of foliages of major browse species. Samples of foliages from 12 and 10 browse species were collected during the wet and dry seasons, respectively. The samples of the browse species were collected based on their abundance in the district, preference by livestock to browse them, accessibility to browsing and their additional uses other than livestock feed. The neutral detergent fiber (NDF) was higher in the browse species during the wet compared to the dry season except for Sterculia africana and Ziziphus spina-christi. Similar trends were observed for acid detergent fiber (ADF) content except for Acacia asak. The condensed tannins content and the IVDMD of the browse species had inverse relationships in both seasons. The in sacco dry matter (DM) and nitrogen degradability parameters of the browse species were seasonally variable. Based on in sacco potential DM and nitrogen degradation of the browse species in both seasons, Acacia oerfota, Acacia tortilis, Balanites aegyptiaca, Boswellia papyrifera, Sterculia africana, Terminalia brownii and Ziziphus spina-christi were ranked to be superior in their nutritive value, and thus can have better use as animal feeds. Consequently, these browse species could be considered in agro-forestry systems for better integration of livestock production with available feed resources in semi-arid areas.

“…Nitraria retusa is an important sand controller, its leaves and twigs are occasionally grazed by sheep, goats and camels (Le Houérou, 1980;Heneidy, 1996). Its fleshy red fruits are eaten by human beings and birds, the wood is used as fuel by the local inhabitants (Kassas & Girgis, 1965) and the bitter fleshy leaves are used as poultice (Jafri & El-Gadi, 1977).…”

“…It is an important sand controller, and its leaves and twigs are occasionally grazed by sheep, goats and camels (Heneidy 1996). The Chenopodiaceae Atriplex halimus is a Mediterranean xero-halophyte saltbush species, highly resistant to drought (Le Houerou 2000), and salinity (Bajji et al 1998).…”

Nitraria retusa and Atriplex halimus (xerohalophytes) plants were grown in the range 0-800 mM NaCl while Medicago arborea (glycophyte) in 0-300 mM NaCl. Salt stress caused a marked decrease in osmotic potential and a significant accumulation of Na ? and Cl -in leaves of both species. Moderate salinity had a stimulating effect on growth rate, net CO 2 assimilation, transpiration and stomatal conductance for the xero-halophytic species. At higher salinities, these physiological parameters decreased significantly, and their percentages of reduction were higher in A. halimus than in N. retusa whereas, in M. arborea they decreased linearly with salinity. Nitraria retusa PSII photochemistry and carotenoid content were unaffected by salinity, but a reduction in chlorophyll content was observed at 800 mM NaCl. Similar results were found in A. halimus, but with a decrease in the efficiency of PSII (F 0 v/F 0 m) occurred at 800 mM. Conversely, in M. arborea plants we observed a significant reduction in pigment concentrations and chlorophyll fluorescence parameters. The marked toxic effect of Na ? and/or Clobserved in M. arborea indicates that salt damage effect could be attributed to ions' toxicity, and that the reduction in photosynthesis is most probably due to damages in the photosynthetic apparatus rather than factors affecting stomatal closure. For the two halophyte species, it appears that there is occurrence of co-limitation of photosynthesis by stomatal and non-stomatal factors. Our results suggest that both N. retusa and A. halimus show high tolerance to both high salinity and photoinhibition while M. arborea was considered as a slightly salt tolerant species.
