Abstract

Determination of grazing capacity in addition to rangeland production depends on various factors which FORAGE QUALITY is the most important. This study was conducted to obtain general information from nutritive value of three province rangelands of Semnen , Markazi and Lorestan. Samples were collected randomly from main vegetation community of each province during two years. Then nitrogen and acid detergent fiber were measured to estimate crude protein, dry matter digestibility and metabolizable energy. To determine forage requirement of animals, dominant sheep breed in each region wase considered. Then forage requirement of each animal unit was estimated based on live weight. The results showed that there were no significant differences (p<0.05) between FORAGE QUALITY in three provinces and three palatability classes. However there were significant differences between FORAGE QUALITY of Plant families (p<0.05). In three provinces of SEMNAN, Markazi and Lorestan crude protein ranged 8.8, 9.5 and 9 percent, acid detergent fiber varied from 40, 41 and 43 percent and average dry matter digestibility were 54, 54 and 52 percent respectively. Metabolisable energy obtained 7.2, 7.1 and 6.9 Mj/Kg DM. According to the results daily forage requirement of Sangsary sheep breed in SEMNAN was 1.3 kg dry matter. Louri sheep was dominant breed in Lorestan with daily requirement of 1.6 kg/DM. while Farahani and Zandi were two dominant sheep breeds in Markazi province with daily requirement of 1.25 and 1.63 Kg/DM respectively. Generally FORAGE QUALITY in the provinces showed that if suitable grazing season be selected, ANIMAL REQUIREMENT for maintenance condition is met by rangelands. However vegetation composition and contribution of each species in range production should be taken in to account.
