Nutritive Value of Some Herbages for Dromedary Camel in Iran

A. Towhidi    

Abstract: To prepare standard tables of chemical composition of feedstuffs and to determine digestibility and palatability of different plant species in dromedary camel, this research was carried out by considering the most consuming herbages of Iranian desert rages. The plant species were included Atriplex lentiformis, Alhagi persarum, Seidlitzia rosmarinus, Saueda fruticosa, Haloxylon ammodendron, Tamarix kotschyi, Hammada salicornica, Salsola yazdiana, Salsola tomentosa, Tamarix aphylla and Artemisia sieberi. Thirty samples of the browsing parts were collected from the rangelands of Yazd province in autumn. Chemical composition of samples including Dry Matter (DM), Crude Protein (CP), Crude Fiber (CF), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Ether Extract (EE), Total Ash (TA), macro elements (Ca, P, Mg, K), micro elements (Fe, Mg, Cu, Zn)and gross energy (GE) were analyzed. The in vitro digestibility was determined by camel rumen liquor in Tilley and Terry method. Palatability of the plants were measured by three mature camels in cafeteria trials. The camels voluntarily fed 11 plant species during one hour for six days. Data were analyzed by GLM method in SAS software. The highest CP (18.3%) and the lowest NDF (40.4%) and ADF (35.4%) were related to Tamarix aphylla. The lowest CP (5.5%) and the highest NDF (72.8%) and ADF (59.6%) were related to Artemisia sieberi. The highest organic matter digestibility in dry matter was related to Haloxylon ammodendron. The results also indicated that Atriplex lentiformis, Alhagi persarum, Seidlitzia rosmarinus, Saueda fruticosa, Haloxylon ammodendron, Salsola tomentosa, Hammada salicornica, Tamarix kotschyi, Salsola yazdiana, Tamarix aphylla and Artemisia sieberi were more pleasure feed, respectively. It was not observed any correlation between %DOMD and chemical composition. Moreover, There was not a consistent relationship between the palatability of herbages with %DOMD or chemical composition.
