چکیده

به منظور تعیین رفتار چرایی بز تالی به عنوان دام غالب منطقه، این بررسی در منطقه زمین‌سنگ استان هرمزگان از سال 1385 به مدت چهار سال انجام شد. شاخص‌های مورد بررسی این تحقیق شامل زمان ورود و خروج دام از مرتع، مسافت روزانه طی شده توسط دام، مسیر دام در مرتع با توجه به شیب آن، حداکثر و میانگین سرعت دام، همچنین مدت زمان استراحت، حرکت و چرای دام در روز بود. برای تعیین شاخص‌های ذکر شده از دستگاه موقعیت‌یاب جغرافیایی جی‌پی‌اس گارمین استفاده گردید که با استفاده از کمربندی مخصوص به پشت یک بز سه ساله بسته شده و پس از خروج دام از آغل فعال شده، سپس در پایان روز داده‌های آن با استفاده از مدتراک در محیط الویس استخراج گردید. مسیر حرکت دام به انتخاب چوپان مشخص ‌شد. نتایج رفتار چرایی دام در ماه‌های فصل چرا برای چهار سال مورد مطالعه نشان داد که در بین سال‌ها، فقط میانگین سرعت دام در سال چهارم و برای ماه‌های فصل چرا نیز تنها زمان حرکت و زمان استراحت در ماه‌های چهارم و پنجم معنی‌دار شد و دیگر خصوصیات رفتاری چرای دام اختلاف معنی‌داری نداشتند. همچنین در طی سال‌های بررسی 31 تا 39 درصد از زمانی که دام در مرتع حرکت می‌کرد به چرا اختصاص داشت.

چکیده [English]

This research was aimed to determine the grazing behavior of Tali goat, as the dominant livestock, in the Zaminsang rangelands of Hormozgan province for four years starting from 2006. The indices examined in this study included the time of livestock entry to and exit from rangelands, the daily distance moved by the livestock, the livestock path, maximum and average livestock speed, and the time spent for livestock rest, movement and grazing. To determine the mentioned indices, the GARMIN GPS was used and closed with a special belt behind a three-year-old goat. The GPS was activated when the livestock exited the barn. Then, at the end of the day, its data were extracted in the Ilwis software.  The path of livestock movement was determined by the shepherds. According to the results, significant differences were found for the average speed of livestock in the fourth year, and the movement time and rest time in the fourth and fifth months, while no significant difference was found for other behavioral characteristics of livestock grazing.  Moreover, during the study period, 31 to 39 percent of the time the livestock moved in the rangeland was dedicated to grazing.
