| چکیده | ||
| مراتع از گونههای مختلف گیاهی با خصوصیات رویشی و فنولوژی متفاوت تشکیل شده که ارزش چرایی معینی دارند. از این روی دام چرا کننده نیز بر حسب آن از خود رفتار چرایی خاصی بروز میدهد. بدون شناخت این رفتارها، برنامهریزی و مدیریت مرتع و دام مقدور نمیباشد. برای پی بردن به رفتار چرایی دام، سایت نیک در مراتع کوهستانی مازندران در منطقه پلور انتخاب گردید. رفتار چرایی دام مانند مسافت طی شده در روز، سرعت حرکت دام، زمان صرف شده برای حرکت، استراحت و چرا با استفاده از GPS مورد بررسی قرار گرفت. زمان بررسی از سال 1389-1386 بوده است. نتایج نشان میدهد که رفتار چرایی دام در ماههای مختلف فصل چرا متفاوت میباشد. رفتار چرایی دام در سالهای مختلف دارای اختلاف معنیدار نمیباشد. بیشترین میزان حرکت دام (دقیقه)در کلاس شیب 30-15 درصد و کمترین آن در کلاس شیب بیشتر از 60 درصد میباشد. به طور میانگین، دام در ماه اول فصل چرا مسافت 14.84 کیلومتر، در ماه دوم مسافت 30/13 کیلومتر و در ماه سوم مسافت 38/12 کیلومتر را طی مینماید. | ||

| چکیده [English] | ||
| Rangelands consist of different plant species with different vegetative and phenological characteristics that have a certain grazing value. Accordingly, livestock reveals particular grazing behavior. Without knowing these behaviors, range and livestock planning and management is not feasible. To understand the livestock behavior, The Niak site was selected in the mountain rangelands of Mazandaran in the Plour region. Livestock grazing behavior such as the distance traveled daily, the speed of the livestock, the time spent moving, resting and grazing were investigated using GPS. The study period was from 2007 to 2010. The results showed that livestock grazing behavior was different in different months of the season. Livestock grazing behavior showed no significant differences in different years. The maximum livestock movement (min) was recorded in slope class of 15- 30% and the lowest in slope class more than 60%. On average, the distance traveled by livestock in the first, second and third month of the grazing season was calculated to be 14.84 km, 13.30 km, and 12.38 km, respectively. | ||
