Abstract

Information on animal requirements for RANGEland grazing capacity is essential. Therefore, animal unit equivalent (AUE) of each breed should be determined independently. In this research, live weight of Gharagol sheep based on average live weight of 3 and 4 years old ewes was determined. Then, two herds of Gharagol breed were selected. Within each herd, 15 three year old ewes, 15 four year old ewes, 5 three years old rams, 5 four year old rams, 10 three month old lambs and 10 six month old lambs have been selected. They were weighed two times including; at the time of end of grazing season in lowland and in winter. For determination of dry matter requirement, forage quality was taken in to consideration. According to the results; weight of Gharagol sheep (three and four years old ewe) was 53.53 ± 0.88 kg and weight of ram and lamb was 89.53±0.96 and 30.70±1.17 kg. Therefore, animal unit equivalent (AUE) for ewe, ram and lamb were 1.05, 1.55 and 0.69 respectively. According to MAFF equation (1984); daily METABOLISM ENERGY requirement for maintenance condition of ewe, ram and lamb Gharagol sheep by considering condition of RANGElands and distances from watering points and plant density was calculated 10.71, 15.81 and 9.15 Mj (including that multiplied by 1.5). Dry matter requirement based on forage quality for ewe, ram and lamb Gharagol sheep were calculated 1.50, 2.26 and 1.02 kg, respectively.
