Abstract

While grazing in rangelands, the livestock select the species and some species are preferred over others. In this study, PREFERENCE VALUE of the species was investigated during 2007 to 2010 at BINALOOD rangelands in Khorasan Razavi province. This research was performed using TIMING METHOD and filming the LIVESTOCK GRAZING for three times per year during the grazing season. The results of grazing time percentage for each species were analyzed by SAS software. Among the rangeland species, those grazed by sheep at least two years were analyzed. Results indicated that Agropayron intermedium was more grazed compared to other species. Scariola orientalis, Convolvulus arvensis, the flowers of Onobrychis cornata and Eremurus spectabilis were highly considered by livestock and allocated most of the grazing time followed by Agropayron intermedium. Also, the percentage and degree of palatability of some species showed significant differences at various stages of filming and during the study years, so that most grasses had a greater palatability in vegetative growth stage, which declined in the later stages. In contrast, livestock preference for some species such as Iris songarica and Verbascum songaricum increased during the final stages of growth.
