This study was conducted to evaluate the effects of Allzyme addition on biologically-treated date-palm mulch (DPM) based diets for growing rabbits. DPM was treated by Trichoderma viride , Trichoderma reesi 230, Plorotus oysterous , and Phanaerochyte chrysosporium . Eighty rabbits were assigned to four groups: a control group, tDPM (10% tDPM inclusion of total diet), Allzyme (Allzyme supplementation), and tDPM + Allzyme (tDPM and Allzyme supplementation). The biological treatment resulted in a significant increase in crude protein and reductions in crude fiber. There was an interaction between tDPM and Allzyme at 9- and 10-week BW. The negative effects of tDPM on BW started at 8-week of age. The tDPM had unfavorable effects on slaughter and meat quality traits. The tDPM-by-Allzyme interaction affected total protein and globulin concentrations. However, blood glucose concentration was influenced by both tDPM and Allzyme. A significant tDPM effect was detected on the expression of INSR, GHSR, and IGF1 genes. However, the Allzyme effect was significant for PPARg and FASN genes. In conclusion, feeding tDPM negatively impacted rabbit's performance, however, Allzyme supplementation alleviated some of those effects. Accordingly, tDPM is recommended to be included in the diets of growing rabbits along with Allzyme supplementation. |
