This study was conducted to investigate effects of bee venom (Apis mellifera L.) on the calving, reproductive efficiency of Hanwoo dams and the growth performance and disease occurrence of calves. Eighty seven experimental dams were allocated into two groups, bee venom treated (n=53, BV) and non-treated (n=34, control) of Hanwoo dams in Icheon, Kyonggi province. Calving period (14.08±4.8) and percentages of retained placenta (7.5%) in BV was shortened compared to control (17.2±4.3, 14.7%, respectively. P¤0.05). Post-placenta periods was similar between two groups (P¤0.05). Postpartum days (36.5 ±4.3) to first estrus and calving interval (358±18) were shortened compared to control (40.2±5.2, 375± 23, respectively) but have not significantly affected (P¤0.05). Body weights (43.5±3.0) and average daily gains (0.62) of calves before 30 days old in BV were significantly higher than control (40.3±5.3, 0.52, respectively). The occurrence of respiratory disease and diarrhea in BV was relatively lower compared with Control. The present results indicate that bee venom may affect reproductive efficiency of dams and growth performance of calves.
