Abstract

One of the important factors in determining the grazing capacity of rangelands is determining the preferred value of rangeland plants according to the type of livestock using the rangeland and its changes during the grazing season. In this study, the preference value of rangeland species in Zaminsang rangeland in Hormozgan province in the months of grazing season (January to May) and different years (2007-2010) was investigated. To determine the preference value, the method of utilization percentage of plant species and determination of preference index were used. The results were analyzed in a split plot statistical design in time in a randomized complete block design in SAS software and the statistical mean of the studied trait was compared with LSD test. The results showed that the most preferred livestock is primarily Aeluropus lagopoides and Atriplex leucoclada and Alhagi graecorum. The lowest percentage of exploitation was from Halocnemum strobilaceum and Desmostachya bipinnata. Based on the preference value index classification, Aeluropus lagopoides and Atriplex leucoclada species are relatively palatable species (relative preference), Alhagi graecorum and Halocnemum strobilaceum species are moderately palatable species (moderate preference) and Desmostachya bipinnata was one of the almost non-palatable (relative avoidance) species.
