Abstract

Animalunit requirement is calculated 1.5-2Kg dry forage for each day in grazing capacity estimation, but FORAGE QUALITY differs from one plant to another, region to region, and in different growth periods. Thus, calculation of ANIMAL UNIT REQUIREMENT/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> ANIMAL UNIT REQUIREMENT based on FORAGE QUALITY will be a more reliable indicator than using 1.5-2kg dry mater when estimating grazing capacity. ANIMAL UNIT body weight of the Lori- Bakhtiari sheep was determined to be about 50 kg. ANIMAL UNIT REQUIREMENT/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> ANIMAL UNIT REQUIREMENT in maintenance condition and grazing in RANGELANDS (0.6 times of keeping in a stable) was extracted from NRC tables based on crude protein (152 gr.), metabolic energy (13.4 mJ) and 2 percent body weight forage (1.6 kg). FORAGE QUALITY was measured for nine vegetation types in the region. With consideration of animal requirement and vegetation composition of each vegetation type, forage quantity that supplied metabolic energy, crude protein, and 2 percent body weight dry mater was calculated in maintenance condition and grazing in RANGELANDS. Using completely randomized design with 3 treatments and 9 replicates for each treatment, statistical comparison of FORAGE QUALITY that provided animal requirement showed significant differences (P<0.01).These results showed the necessity of calculating ANIMAL UNIT REQUIREMENT/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> ANIMAL UNIT REQUIREMENT based on FORAGE QUALITY in different regions and conditions.
