Effects of honeybee venom supplementation in drinking water on growth performance of broiler chickens.

The effects of water supplementation of bee venom (BV) on performance, antioxidant activity, and liver function in Arbor Acres broiler chickens were investigated. Hence, 3 experimental treatment groups (control, 0.5 mg/L of BV, and 1 mg/L of BV) were allocated to 3 replicates of 5,000 one-day-old chicks each. The control group was kept on tap water, whereas the other 2 groups were supplied water supplemented with 0.5 and 1 mg of BV, respectively, per liter of drinking water. Broilers were provided ad libitum access to feed for the experimental period of 1 to 28 d of age. Supplementing drinking water with BV significantly increased BW gain at 28 d of age (P < 0.05). The average daily weight gain from d 1 to 28 was increased for birds supplemented with BV compared with control birds. The increase in BW gain was more pronounced with supplementation of 1 mg/L of BV compared with 0.5 mg/L of BV. An improved feed intake was noted in groups supplemented with BV as compared with control chicks. Liver function enzymes, aspartate aminotransferase, and alanine aminotransferase activities including total cholesterol, total protein, albumin, and globulin were not changed by BV supplementation. Tap water supplementation of BV did not alter the number of leukocytes, erythrocytes, heterophils, and lymphocytes. However, the antioxidative activities estimated as a superoxide dismutase-like activity of broiler chicks supplemented with BV was significantly increased (P < 0.05) in comparison with those without BV supplementation. These data indicate a possibility of better broiler performance through BV supplementation under conditions of severe stressful challenges the newly born chicks encounter.
