Abstract

ABSTRACT
The present study aimed to compare the impact of oral administration of date palm pollen (DPP) or bee pollen (BP) in suspension form on rabbit bucks' physiological and reproductive performance traits. Fifty V-line male rabbits at 20 weeks of age were divided into five equal groups; Control group was given water (placebo), DPP groups (DPP1, 150 mg/kg BW; DPP2, 300 mg/kg BW), and BP groups (BP1, 200 mg/kg BW; BP2, 400 mg/kg BW). During a 12-week period, supplements were taken three times a week (Sunday, Tuesday, and Thursday). Blood samples (either plasma or serum) were collected at 32 weeks of age to examine the hematological and biochemical constituents. Also, at 28 weeks of age, semen was collected to evaluate some semen quality traits and seminal plasma metabolites.
Results indicate that white blood cells (WBCs) and lymphocytes increased significantly in the high level of both supplements compared to the control group. Meanwhile, the BP2 group had an increase in red blood cells (RBCs), hemoglobin (Hgb), and Packed cell volume (PCV) and a decrease in urea significantly compared to control without significant difference between treatments. Furthermore, high density lipoprotein (HDL) and testosterone were increased in the treated rabbits, as well as decreased in low density lipoprotein (LDL), very low density lipoprotein (VLDL), and Alanine aminotransferase (ALT) significantly compared to the control. there was an increase in the total antioxidant capacity (TAC) and testosterone concentration in the treated groups compared with the C rabbits. These results indicated that DPP and BP, which were natural additives considered safe as they improved the immune and physiological parameters and reproductive performance of rabbit bucks.
Accordingly, from an economic point of view it could recommend using levels of DPP (150 mg/kg BW) or BP (200 mg/kg BW) to improve the biochemical, immunological, physiological, and subsequently bucks reproductive performance.
