Productive Performance, Blood Constituents and Some Physiological Parameters of Rabbit Bucks Administered With Bee Pollen Under Hot Conditions Prevalent in Assiut

Abstract

The impact of treatment with bee pollen (BP) on the productive performance and some hematological and physiological traits of rabbit bucks were studied under hot climatic conditions prevalent in Assiut during the summer season. A number of 30 rabbit bucks (15 Vline & 15 Moshtohor line); 14 weeks old were divided into three equal experimental groups. The bucks of 1 st group were fed on a commercial basal ration and served as control, while those in the 2 nd and 3 rd groups were fed on the same ration in addition to daily oral supplementation with 250 and 500mg BP/buck, respectively in gelatin capsulated form allover experimental period. The obtained results revealed significant rabbit line differences in total feed intake (TFI/g), RBCs (10 6), total protein (TP), glucose (mg/dl), total lipids (g/L), aminotransferase(ALT/IU/L), IgG (mg/dl), IgM (mg/dl) and Tri-iodothyronine (T3/ng/dl) hormone concentration. While, the differences were insignificant in the productive traits, Hb (g/dl), HTC (%), cholesterol (g/dl), total antioxidant capacity (TAC/mm/l), aspartate aminotransferase (AST), follicle-stimulating hormone (FSH), testosterone (Testos) and Luteinizing hormone (LH) hormone concentrations. The total feed intake of bucks treated with 250 and 500mg BP/buck decreased by 4.45 and 8.48%, but the means of BW (g), BWG (g) and PI (%) increased significantly (P0.01 or 0.05) than those of the control. The means of Hb (g/dl), HTC (%), RBCs (10 6) and Lymphocytes (%) of the bucks treated with BP increased significantly (P0.01 or 0.05) than those of the control. The means of TP, albumin, globulin (g/dl) and glucose (mg/dl) levels as well as TAC (%), IgG (mg/dl), IgM (mg/dl) of the treated bucks significantly (P0.

Influence of Using Date Palm Pollen or Bee Pollen on Some Blood Biochemical Metabolites, Semen Characteristics and Subsequent Reproductive Performance of v-Line Male Rabbits

“…Also, the PCV ratio in BP2 and DPP2 rabbits were highest (P<0.05) compared with the C group by (20.74% and 17.65%, respectively). The present study results indicated that treating rabbits with DPP and BP had improved the hematological variables, which are in agreement with the previous results of Abuoghaba et al, (2017), El-Neney and El-Kholy, (2014), Khalil et al, (2015), andTaghian, et al (2017). Treatment with both 250 and 500 mg BP/buck of rabbit bucks raised in hot, humid environments showed significant improvement in the RBCs, lymphocytes, and neutrophils parameters (Abuoghaba et al, 2017).…”

Also, BP significantly increased RBC and WBC counts in rabbits compared with control (Neney and El-Kholy, 2014).…”

“…In addition, treatment with BP significantly increased the levels of RBCs, neutrophils, and lymphocytes in Baladi rabbit bucks (Khalil et al, 2015). The increased total WBCs, lymphocytes, neutrophils, and RBCs count and Hgb concentrate for treated bucks may be due to the vital role of DPP and BP in enhancing the immune functions (Abuoghaba et al, 2017). Besides, the improvement of the RBCs ratio increased the packed cell volume ratio represented by PCV, PA, PI, and BA.…”

Bee Products for Poultry and Rabbits: Current Challenges and Perspectives

“…Despite some of these substances being considered by-products, they are sources of bioactive compounds with relevant biological effects and significant impacts on animal physiological and productive performance [4,29,30]. Several studies have found that bee products, with a high content of essential amino acids, antioxidants, active enzymes, vitamins, minerals, antibacterial, antiprotozoal, and immunostimulant substances, can improve animals' growth, meat quality, and immunological performance [3,4,[31][32][33][34] (Figure 1). Rabie et al [29] found that administering propolis (400 mg/kg diet) or bee-pollen (2 g/kg diet) to the broiler diets as well as adding bee-venom (2 mg/L water) to broiler drinking water is recommended instead of using antibiotics in broiler farms to increase body weight and improve blood biochemical indices.…”

“…According to Yıldız et al [77], supplementation of bee pollen under stress lowered the oxidative stress indicators and increased the antioxidant system of animals. Moreover, Abuoghaba et al [31] found that dietary supplementation of bee pollen (500 and 1000 mg/kg diet) to breeder hens improved several hatching and hematological traits, in addition to reducing the adverse effects of heat stress on chicks treated with thermal manipulation during egg incubation.…”
