Abstract: This study was carried out to evaluate the effects of adding two treatments (biological or chemical) on degradability and productive performance of Ossimi lambs. Thirty Ossimi lambs with average body weight 18.00±0.20 kg and 4 months old were used in this study. Lambs were distributed into five similar groups (6 lambs each). They were randomly assigned to the five experimental diets. Animal groups were fed the five respective rations composed of concentrate feed mixture (CFM) + roughage (pruning grape trees by-products), (RI) the control ration contained untreated roughage, (R2) roughage treated with 3% urea, (R3) roughage treated with Trichoderma reesei; (R4) roughage treated with Trichodenna viride and (R5) roughage treated with Trichoderma reesei + Trichodenna viride. The DM, OM and CP disappearance values were in situ determined with untreated or treated roughage and effective degradability (ED) was assessed. Fractions of DM (a and b) and ED were significantly (P<0.05) increased with treated roughage either with urea or fungi compared to control (untreated). The highest degradable values of DM were observed with R5. The similar trend was observed for OM and CP degradability. Nutrients digestibilities and nutritive values (TDN and DCP) were significantly higher (P<0.05) for rations containing treated roughage (R5, R4, R3 and R2) compared to control one (R1). The highest TDN and DCP values (60.40 and 8.31 %, respectively) were noticed for R5 compared to those for other rations. Generally, the biological treatments (R5, R4 and R3) increased all nutrients digestibility, digestibility of cell wall constituents (NDF, ADF, cellulose and hemicellulose) and improved feeding values (TDN and DCP%). Ruminal NH3-N and TVFA's concentrations were significantly increase by urea and biological treatments. However, the differences in blood constituents (total protein, albumin, globulin, and urea) were not significant (P>0.05) among the different experimental rations except blood urea and globulin were significantly higher (P<0.05) in the second group (urea treatment). Blood constituents were generally normal in all experimental groups. Results of growth performance showed that there were improvements with respect to total body gain and ADG in groups R3, R4 and R5. Feed conversion was significantly (P<0.05) improved for lambs fed rations contained biological treatments (R3, R4 and R5) followed by R2 and the least one of R1. It could be concluded that biological and chemical treatments for pruning grape trees by-products to rations of growing Ossimi lambs improved their performance, digestibility, average daily gain and feed conversion and the best results were achieved with R5 treatment with two fungi.

Keywords: biological treatments, fungus, digestibility, blood and ruminal parameters.
