چکیده

این آزمایش به‌منظور بررسی هضم‏پذیری و فراسنجه‏های تخمیر جیره‏های حاوی برگ، غلاف با دانه، و گل درخت برهان در گوسفند با روش‏های هضم دومرحله‏ای و تولید گاز انجام شد. جیره‏های آزمایشی شامل سطوح صفر، 25، 50، 75، و 100 درصد برگ، غلاف، و گل برهان بودند. نتایج نشان داد بیشترین قابلیت تولید گاز مربوط به جیرۀ حاوی 50 درصد برگ بود (05/0P<). نرخ تولید گاز در جیرۀ حاوی 75 درصد گل از سایر جیره‏ها بیشتر بود (05/0P<). عامل پارتیشنینگ، تولید تودۀ میکروبی، و بازده تودۀ میکروبی در جیرۀ حاوی 100 درصد برگ و سطوح متفاوت غلاف بالاترین بود (05/0P<). قابلیت هضم مادۀ خشک در جیره‏های حاوی سطوح مختلف برگ، 50 درصد گل، و 25 درصد غلاف برهان، و قابلیت هضم الیاف نامحلول در شویندۀ خنثی در جیره‏های حاوی سطوح مختلف گل و 25 درصد غلاف برهان در مقایسه با جیرۀ شاهد بالاتر بود (05/0P<). کمترین غلظت نیتروژن آمونیاکی مربوط به جیره‏های حاوی 100 درصد برگ و غلاف با دانۀ برهان بود (05/0P<). براساس این نتایج، می‏توان از برگ، گل، و غلاف با دانۀ برهان به جای یونجه در جیرۀ گوسفند استفاده کردد و هضم‏پذیری و تخمیر شکمبه‏ای جیره را افزایش داد.

چکیده [English]

This experiment was conducted to investigate the digestibility and fermentation parameters of diets containing flower, pod with seed and leaf of siris in sheep by two-step digestion and gas production methods. The experimental diets were including zero, 25, 50, 75 and 100 percent of Siris flower, pod and leaf. The result showed that gas production potential of diet containing 50 percent leaf was greater than other treatments (P<0.05). Gas production rate of diet containing 75 percent flower showed significant increase compared with the other diets (P<0.05). Partitioning factor, microbial biomass, biomass efficiency were the greatest for diets containing 100 percent leaf and different levels of pod (P<0.05). Dry matter digestibility of diets including different levels of siris leaf, 50 percent siris flower and 25 percent siris pod and neutral detergent fiber digestibility of diets including different levels of siris flower and 25 percent Siris pod were higher compared to control diet (P<0.05). The lowest concentration of ammonia nitrogen was belonged to diets containing 100 percent leaf and pod of Siris (P<0.05). It could be concluded that Siris leaf, flower and pod with seed of siris can be used instaed of alfalfa in sheep diet and increase digestibility and diet ruminal fermentation.
