چکیده مقاله:

The nutritive value of pistachio epicarp (PE) was evaluated by in situ and in vitro techniques. Chemical analysis indicated that PE was high in crude protein (۱۱.۳۰%) and low in neutral detergent fiber (۲۶.۲۰%). Total phenols, total tannins, condensed tannins and hydrolysable tannins contents in PE were ۸.۲۹%, ۴.۴۸%, ۰.۴۹% and ۳.۷۹%, respectively. Ruminal dry matter and crude protein degradation after ۴۸ hr incubation were ۷۵.۲۱% and ۸۲.۵۲%, respectively. The gas production volume at ۴۸ hr for PE was ۱۲۲.۴۷ mL g-۱DM. As a whole, adding polyethylene glycol (PEG) to PE increased (p < ۰.۰۵) gas production volumes, organic matter digestibility and the metabolizable energy that illustrated inhibitory effect of phenolics on rumen microbial fermentation and the positive influence of PEG on digestion PE. The results showed that PE possessed potentials to being used as feed supplements.
