Abstract
In this research to investigate of the effect of tannin`s type and level on rumenal degradation of soybean meal (SBM) and canola meal (CM), two experiments have be done. At first experiment supplements were treated by semi-pure tannin of pomegranate-pistachio (PP), in different levels (0, 10 and 15 % of DM for SBM and 0, 5 and 10% of DM for CM). In second experiment, these supplements were treated by (PP), pomegranate-tea (PT) and sole pomegranate (P) at same levels (10% of DM). The effects of these treatments on protein fractioning of treated and untreated SMB and CM was determined by, CNCPS system, in comparison with fish meal (FM) and corn gluten meal (CGM), as a sources of bypass protein. According to results, treated SBM by PP 10% (SBM-PP) and treated CM by PP5% could increase bypass protein fraction in comparison with FM and CGM. So it can be concluded that these treatments, could be used in reminant diet to provide by pass protein, but further research is necessary to investigate in vivo effects of these treatments.
