Nutritional composition of three fodder species browsed by camels (Camelus dromedarius) on arid area of Tunisia
ABSTRACT Browsing camels have access to different plant species in relation to the kind of pasture they can reach. A study was conducted in an arid region of Southern Tunisia to determine the dietary preference and forage quality of free ranging camels. Foliage consisting of leaves from Limonium pruinosum, Retama raetam and Stipa tenacissima, was collected during the dry season to evaluate the chemical characteristics and nutritional value of these browse fodder species. The dietary preference was studied using 15 adult camels which were selected from a herd of 50 animals appropriately marked for identification. There was a significant difference in the chemical composition and nutritional value of plant species collected. Based on crude protein (CP) content and nutritional value, the three fodder species browsed can be recommended as good-quality food source for camels under pastoral management.

- "Norton (1994) affirmed that anti-nutritional factors have also been considered as substituent for more luxurious processed protein sources. Wild edible plants are enriched with number of essential nutrients, which are great source of food for the people especially for the rural inhabitants (Laudadio et al., 2009a, b; Barakat et al., 2013). However, these nutritional plants may have some toxic ingredients which are harmful for human The anti-nutritional factor (substances generated by different mechanisms using normal metabolic process) exerts adverse effects against optimum nutrition. "
ABSTRACT: The present study was conducted to evaluate the anti-nutritional composition of the wild plants of Soon Valley, Khushab, Pakistan. Anti-nutritional components posed a high risk to health for the ruminants. So it is very important to estimate the range of anti-nutritional compounds present in the wild plants which are used as forage by the ruminants of this area. Anti-nutritional compounds, such as terpenes, tannins, saponins, phytate, alkaloid, cyanide and oxalate were analyzed. Highest terpene contents (200.33%) were showed by Digitaria sanguinalis, Erigeron divergens showed maximum alkaloid contents (0.93%) while highest cyanide value was observed in Achnatherum hymenoides (0.57%). Excluding cyanide, all anti-nutritional components showed significant variation in all plant species. The values of anti-nutrients observed in the present study are below than the toxic levels. Bulk consumption of monotypic edible parts of plant during one meal may lead to nutritional and health problems. However, traditional methods help to lower down the anti-nutritionals and their respective risks. Similarly, wild edible plants can also be used to improve the living security and thus reduce the starvation due to the millennium development goals. INTRODUCTION Anti-Nutritive Factors (ANF) are compounds which are produced by different mechanisms and affect the utilization of nutrients. These are produced by inactivation of some nutrients and through normal metabolism and affect the utilization of nutrients and digestion of feed. Properties of ANF also depend on digestive process of animal because sometime ANF are degraded in rumen and not show any toxic effect on animals. In monogastric animals, trypsin inhibitor are degradedJournal of Environmental Science and Technology 03/2015; 8(3). DOI:10.3923/jest.2015

- "It resembles L. monopetalum but is readily recognized by its narrower sub-cylindrical leaves, divaricated many-branched inflorescence, and smaller flowers (Quézel & Santa, 1963; Qaiser & Siddiqi, 1984; Boulos, 2000). It has been used in local communities as forage for camels (Laudadio & al., 2009), and recently its medicinal potential has been reassessed (Trabelsi & al., 2012; Debouba & al., 2013; Krifa & al., 2013). From the standpoint of nomenclature, both species names appear to be not yet typified and they are investigated here as part of the researches on the genus Limoniastrum and relatives in both the project " Flora Valentina " (by P.P. Ferrer-Gallego, E. Laguna, and M.B. "
ABSTRACT: The halophytic shrub genus Limoniastrum has recently been recircumscribed to include only two Mediterranean-Saharan species, Limoniastrum monopetalum (L.) Boiss. (≡ Statice monopetala L.) and L. guyonianum Boiss. Protologues of both species are briefly discussed and lectotypes are designated using material at BM (Herb. Clifford) and G (Herb. Boissier).Taxon 12/2014; 63(6):1342-1346. DOI:10.12705/636.4 · 3.30 Impact Factor

- "The ecological conditions in salt marsh ecosystem are fairly severe and fluctuate significantly under the influence of many factors, including pouring annual rainfall, changes in temperature and wind direction, poor skeletal sandy soils and salinity (El-Morsy, 2010). Combinations of these complexity conditions were common features allow only a unique of special natural vegetation to survive in these stressful habitats like halophytes (Laudadio et al., 2009b). The ecophysiological strategies of many halophytes have been studied byseveral authors (Khan et al., 2004; Nedjimi, 2012) mostly agreed that soil salinity, osmotic potential and soil moisture are important factors affecting their growth. "
ABSTRACT: Plants adopt different strategies in response to seasonal variations in their natural biotype. In this study, the responses of seasonal changes on the organic osmolyte contents, ionic homoeostasis, osmotic potential and succulence of native chenopods in a salt marsh of Egypt were studied. Five halophytic species of the chenopodiaceae were collected during the rainy and dry season: Atriplex halimus L., Halocnemum strobilaceum (Pall.), Salicornia fruticosa (L.), Suaeda pruinosa (Lange) and Arthrocnemum macrostachyum (Moric). Results showed that plants employ an osmoconformer strategy via species specificity of response to seasonal variations. The total ions accumulation in all species was higher during the rainy season compared with the dry season. In particular, during rainy season, A. halimus resulted the higher accumulator species, followed by H. strobilaceum. Conversely, S. fruticosa, S. pruinosa and A. macrostachyum were defined as low-accumulator species. In each studied species, the effective salinity, biological absorption coefficient as well as leaf succulence were higher during the rainy season. In conclusion, the present study have pointed out the importance that should be accorded with the development of research directed towards agronomic aspects for the uses of halophytic chenopodiaceae in salt marsh. Further, data obtained indicate that the ions accumulator species should be considered for use in phytoremediation of degraded saline lands.African Journal of Ecology 04/2014; 52:163–172.
