| Abstract | ||
| To study the effect of growth stage on the nutritional value of two rangeland species (Kelussia odoratissima mozaff and Dorema aucheri Boiss) in Kohgiloyeh summer Rangelands, sampling at three stages of vegetative growth, flowering and seeding was performed. The samples were dried and milled in the shadows. Then, the chemical compounds contain Crude Protein, Ether Extract, Ash, Phosphorus, Calcium, content of Neutral Detergent Fiber, content Acid Detergent Fiber were measured in the laboratory. In addition, Dry Matter Digestibility and Metabolizable Energy were calculated. Analyses variance and Tukey’s test were used for all comparisons. The results showed that nutritive value of both species was higher in the vegetative stage than the others stages. CP, Ash, P, Ca, DMD, ME NDF and ADF had significant difference among the three phenological stages in both species (P≤0.05). In general, the nutritional value of Kelussia odoratissima Mozaff. was higher than Dorema aucheri Boiss. | ||
