Impact of Chinese Royal Jelly on Performance, Behaviour and Some Blood Parameters in Broilers Reared under High Stocking Density

Fatma A. Mahmoud
Objective: This experiment was conducted to assess the use of Chinese Royal Jelly (RJ) over a 6 weeks period on performance, behaviour and blood parameters of broilers. Methodology: Approximalty,180 one-day-old Ross broiler chicks were randomly assigned to six treatment groups as follows; Group 1: Control (LSD; 8 birds, per meter square and no supplementation), Group 2: High stocking density (HSD; 16 birds per meter square and no supplementation), Group 3: LSD-RJ 250 (8 birds per meter square and 250 mg kg–1), Group 4: LSD-RJ 500 (8 birds per meter square and 500 mg kg–1 b.wt.), Group 5: HSD-RJ 250 (16 birds per meter square and 250 mg kg–1 b.wt.) and Group 6: HSD-RJ 500 (16 birds per meter square and 500 mg kg–1) RJ given orally. Scan sampling for comparative behavior in all groups was carried out at 2 min intervals during 2-20 min periods for 5 days each week. Results: The highest Feed Intake (FI), Feed Conversion Rate (FCR) and Body Weight Gain (BWG) were recorded in the LSD group (p<0.05) fed on diet supplemented with Chinese Royal Jelly (RJ) compared to other treatments during the experimental period. Also, FI, FCR and BWG were significant (p<0.05) improved in HSD-RJ 250 and HSD-RJ 500 compared to other groups. It was found that a significant higher proportion of chicks in RJ supplemented groups were engaged in feeding, resting, walking, standing, foraging and preening behaviour however, drinking behaviour was not significant influenced (p>0.05) by RJ supplementation. Chicks fed 500 mg of RJ were found to have the highest values of the heterophils and lymphocytes. Serum total protein, albumen and globulin concentrations were significantly (p<0.05) boosted in the RJ groups compared to the controls. Conclusion: The study was completed concluding that Chinese royal jelly supplementation can alleviate the deleterious effect of high stocking density in Ross broiler chicks, improved behaviour, performance and blood parameters in the examined broiler chicks under high stocking density.
