| چکیده | ||
| آزمایش حاضر به‌منظور بررسی ترکیب شیمیایی و خصوصیات هضمی و تخمیری برگ توت سیاه و یا جیرههای حاوی مقادیر صفر، 25، 50، 75 و 100 درصد از آن، توسط جمعیت کامل میکروارگانیسمها یا قارچهای شکمبه گوسفند، انجام گرفت. ماده خشک، پروتئین خام، الیاف نامحلول در شوینده خنثی (NDF) و اسیدی (ADF)، خاکستر و تانن برگ توت سیاه به‌ترتیب 5/96، 3۰/19، 82/36، 9۰/15، 31/۹ و 3۰/0 درصد بود. مقدار عامل تفکیک‌کننده، ماده آلی واقعاً تجزیه شده، تولید توده میکروبی و بازده آن در توت سیاه بیشتر از علوفه یونجه بود (05/0>P). با افزایش مقدار برگ توت در جیره تولید گاز افزایش یافت، به‌‌طوری‌که جیره حاوی 30 درصد برگ توت بیشترین پتانسیل تولید گاز را داشت (05/0>P). با افزایش مقدار برگ توت در جیره تجزیه دیواره سلولی، قابلیت هضم ماده آلی، انرژی قابل متابولیسم و اسیدهای چرب کوتاه زنجیر افزایش یافت (05/0>P). بنابراین، جایگزین کردن علوفه یونجه با برگ توت در جیره اثر منفی بر فعالیت هضمی میکروارگانیسمها، به‌ویژه قارچهای جداشده شکمبه که بیشتر هاضم الیاف و بخشهای سخت گیاه هستند، ندارد و می‌توان از برگ توت به دلیل پروتئین بیشتر و الیاف کمتر، به جای یونجه در جیره بره‌های پرواری استفاده کرد. | ||

| چکیده [English] | ||
| This experiment was conducted to determine chemical composition, and fermentation and digestion characteristics of black mulberry leaves, or diets content 0, 25, 50, 75 and 100% of it, by whole rumen microorganisms or rumen fungi. Dry matter, crude protein, NDF, ADF, Ash and tannin of the black mulberry leaves was 96.5, 19.30, 36.82, 15.90, 9.31 and 0.30%, respectively. Partitioning factor, truly organic matter degradability, microbial biomass and microbial biomass efficiency in the black mulberry leaves were more than alfalfa hay (P<0.05). The gas production was increased by increasing amount of the black mulberry leaves, so that diet contains 30% of the black mulberry leaves had the hiegest gas production (P<0.05). The organic matter digestibility, cell wall degradability, metabolizable energy and short chain fatty acids of experimental diets increased by increasing the amount of the black mulberry leaves in diet (P<0.05). Therefore, the replacement of the alfalfa hay with black mulberry leaves in diet, has no negative effect on rumen microorganisms, especially isolated rumen fungi which are the digester of fiber and harsh parts of plants, and due to the higher protein and lower fiber contents of the black mulberry leaves, may be replaced it instead of alfalfa hay in fattening lamb diets. | ||
