Abstract :

این تحقیق به منظور تعیین مقدار تولید مو و ویژگی‎های الیاف بزهای مویی لری با توجه به سن و جنس آنها انجام گرفت. داده‏های آزمایش مربوط به اطلاعات به‌دست آمده از 73 بز در دو گروه سنی (یکساله و بزرگتر از یکساله) و از هر دو جنس (26 بز نر و 47 بز ماده) بودند. متوسط وزن بیده، طول تار، طول استاپل، راندمان بیده، قطر الیاف، ضریب‌ تغییرات قطر الیاف، ضریب ‌پارگی، مقاومت و قابلیت ارتجاعی اندازه‌گرفته‌ شده به‌ترتیب عبارت بودند از: 7/23 ± 429 گرم، 3/0 ± 2/6 سانتی‎متر، 4/0 ± 9/8 سانتی‎متر، 6/0 ± 9/73 درصد، 8/1 ± 6/82 میکرون، 8/0 ± 3/24 درصد، 3/0 ± 6/7 کیلوگرم نیرو، 4/0 ± 2/10 گرم نیرو بر تکست و 0/1 ± 0/14 درصد. سن و جنس اثر معنی‎داری برروی وزن بیده و طول استاپل داشتند. در عین حال، طول تار، قطر الیاف و ضریب ‌تغییرات قطر الیاف در دو گروه سنی متفاوت بود. افراد بزرگتر از یکسال الیافی با مقاومت بیشتر (6/0±3/10 گرم نیرو بر تکست) و قابلیت ارتجاعی کمتری (4/1±4/12 درصد) تولید نمودند که نتایج از نظر آماری معنی‎دار نبود.
