چکیده

This experiment was conducted to study the effects of various amounts of treated sunflower meal (SFM) with extracted tannins from pistachio hulls on in vitro gas production and ruminal fermentation in ruminants. The SFM was treated with pistachio extract concentrate (PEC), which contained ۱۱۱.۴۰ g kg-۱ total phenol and ۷۱.۳۰ g kg-۱ total tannin per dry matter of extract, at six experimental treatment levels of ۰, ۷, ۱۴, ۲۱, ۲۸ and ۳۵ g PEC per ۱۰۰ g SFM on a dry matter basis. In vitro gas production, in vitro organic matter digestibility (IVOMD), metabolizable energy (ME) and fermentative parameters of samples were measured. The PEC had no effect on fermentation rate, but asymptotic gas production was linearly decreased with increasing dose of extract. All fermentation parameters (i.e., apparent degraded substrate, short chain fatty acids, gas yield at ۲۴ hr, partitioning factor at ۹۶ hr, IVOMD, ME and microbial protein production (MP) linearly decreased with increasing PEC treatment. Inclusion of PEC linearly decreased ruminal ammonia nitrogen concentration (NH۳-N), total protozoa population and pH in the all incubation times. In conclusion, the addition of PEC positively modified some rumen parameters such as NH۳-N concentration and protozoa population.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
