Abstract
Having a comprehensive and correct understanding of grazing behaviour of livestock helps to maximize livestock products. Moreover, a good understanding of livestock behavior allows us to predict the effects of livestock on rangeland and finally we can do livestock grazing management the best possible. Recognition of grazing behavior of animals can provide solutions enables the optimal use of rangeland forage and can also help in preventing the reduction of animal products and will prevent of Ranchers income loss. For this purpose cow grazing behaviour investigation was performed in Tezkharab rangelands for 4 years. Long distance path following day in the pasture, and livestock speed (maximum and minimum average) time for rest and time for the motion and applied grazing system were studied. To study for grazing cycle was used from the geographic position locator (Garmin GPS). Use the belt to the back of a cow's day package. At the end of the day, data was extracted in Elvis using in track mode. The results showed all traits in a significant level 1% Effect was significant difference in years and months (May, June, July, August, September and October) except average speed traits. This trait was significant at the 5% level. This study showed that environmental factors such as seasonal variations and therefore its temperature changes is one of the most important factors that influencing grazing behavior of livestock.
