This study aimed to evaluate impact of enzymes mixture (EZ) addition to diets containing date stones meal (DSM) on body weight, blood parameters, immune response and carcass characteristics of growing rabbits. Seventy-five New Zealand White (NZW) rabbits,28 days of age with average weight 491±2.77g, were randomly divided into fiveexperimental groups. The 1 st group was fed control diet (Diet A) contained 0% DSM and served as a control. The 2 nd , 3 rd groups, were fed diets contained 10% DSM either without (Diet B) or with EZ (1 g/ Kg diet) diet addition (Diet C), respectively. The 4 th and 5 th groups, were fed diets contained20% DSM either without (Diet D) or with EZ (1 g/ Kg diet) addition (Diet E), respectively. At the end of the experimental period five rabbits from each groupwere taken to determine carcass characteristics, blood parameters and meat quality. Percentages of dressing were significantly (P<0.05) higher in rabbits fed 10% DSM+ EZ than the other groups. The protein and lipid percentage of meat were significantly higher in rabbit fed A, C and E diets than those fed Diet D, the levels of glucose, total lipid, triglycerides, HDL, LDL and RBC's were significantly (P<0.05) higher, whereas GPX and SOD percentages were lower (P<0.05) in rabbits fed A or C diets than the other groups. Higher values of α-globulin, BA and LTT were recorded with rabbits fed A, B or C diets compared with other groups. IgA, IgM and IgG were significantly higher in rabbits fed A, C or E diets than the other groups. No significant differences were 486 EL-KELAWY AND EL-SHAFEY recorded in creatinine, AST, ALT, alkaline phosphates, cholesterol, total protein, albumin, TAC, GSH, globulin, globulin-γ, LA, PI and PA, hematological criteria and differential leucocytes counts among the different groups. Total bacterial, Salmonella, E. Coli and Proteus bacterial counts were significantly lower in rabbits fed B, C, D or E diets than the control group. In conclusion, date stones meal can be included in rabbit diets up to 10% with adding enzyme complex (Kemzyme) without any adverse effects on body weights, blood parameters, immune index, carcass characteristics and meat quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
