Abstract: | Three halophytes from El Oued (Atriplex halimus L., Sueda mollis, Zygophyllum album) which are preferentially grazed by camels, and in addition to the hay of vetch-oats (a reference control substrate), have been analyzed in order to determine their nutritional value for camels. Our study is based on the evaluation of their nutritional potential by measuring the fermentability in vitro by ruminal microbiota of camels. The results of the in vitro rumen fermentation by dromedary microbiota show that, with the exception of Z album, the total gas production, generated by the anaerobic degradation of these substrates, is relatively high compared to that of the reference substrate, contrary to most other domestic ruminants, to which most of studies mention that in vitro gas production is negatively influenced by the fiber content of foods and their content of secondary compounds.These results could be explained either by the fact that our tested substrates contain a highly digestible fiber fraction, or by the digestive and metabolic use capacity of camelin ruminal microbiota of this type of feed, or by the combination of these factors |
