Abstract
The study aimed to determine effects of natural feed additives such as bee pollen (BP), propolis (PRO), date palm pollen (DPP) and pomegranate peel powder (PPP) on performance, carcass traits, digestion coefficient, and some blood metabolites. A total number of 30 weaned detached rabbits at age of five weeks of age with average weight (650±10.00) were used. Rabbits were randomly dispersed into five collections. The treatments were served diet supplemented with 0.00 or 0.20 % of feed additives. In the 1st, rabbits were established un-supplemented and saved as control. While, those in the 2nd, 3rd, 4th and 5th groups were treated with BP, PRO, DPP, and PPP at 0.20% ̸kg diet.
The obtained outcomes from this experiment designated that: 1- Growing rabbits that supplemented with BP significantly (P˂0.05) increased final live weight and total weight gain and decreased total feed intake as well as improved in feed conversion followed by rabbits supplemented with PRO as compared with other groups.
2- Growing rabbits in BP fed group recorded the highest values of carcass and total edible giblet weights and dressing percentage followed by rabbits in PRO group, while rabbits in PPP group recorded significant (P˂0.05) increment for kidneys %.
3- The highest glucose, TP, Glob, TAC and CAT values were recorded in BP fed group. A significant increase in Alb, ALT, AST and SOD and decrease in TChol in PPP fed group, while value of MDA was enhanced significantly for PRO.
4- Digestion coefficient and nutritive values measurements for growing rabbits were increased (P˂0.05) significantly for BP group . 5- Supplementation of BP improved total return, net return and economic value and there is no enhancement for economic efficiency value related to other these feed additives.
Conclusively, from this obtained results it could be concluded that the supplementation of natural feed additives; bee pollen, propilis, date palm pollen and pomegranate peel powder at 0.20% ̸ kg diet had supportive effects on rabbit’s growth performance, carcass characteristics, blood constituents and its antioxidant and digestibility in growing rabbits.
