本试验旨在初步探索中华蜜蜂(Apis cerana cerana)越冬阶段维生素与矿物质的需要量。根据中华蜜蜂天然饲料——蜂蜜中的维生素和矿物质的含量设计试验饲料(维生素中剂量组、维生素高剂量组、矿物质中剂量组、矿物质高剂量组、维生素中剂量+矿物质高剂量组、维生素高剂量+矿物质中剂量组),测定维生素和矿物质对中华蜜蜂越冬阶段蜂群群势削减率和越冬饲料消耗量2个指标的影响,并以糖水和蜂蜜为对照进行比较,研究中华蜜蜂越冬阶段对维生素和矿物质的需求量。结果表明:在越冬阶段,除了使用天然蜂蜜作为越冬饲料外,也可以在中华蜜蜂常规饲料——糖水中添加复合维生素和矿物质来满足蜜蜂越冬的部分营养需求,复合维生素的最佳添加剂量应低于0.08 mg/kg,复合矿物质的最佳添加剂量应在0.95~1.89 mg/kg。
This experiment was conducted to study the requirements of vitamins and minerals for Apis cerana cerana during overwintering period. We detected the contents of vitamins and minerals in honey, which was the natural fodder for Apis cerana cerana during overwintering period, and designed the experimental diets, including medium dose vitamin group, high dose vitamin group, medium dose mineral group, high dose mineral group, high dose vitamin and medium dose mineral group, and medium dose vitamin and high dose mineral group. The effects of these experimental groups were compared with the control group of honey and sugar water (syrup). Feed consumption and reduction rate of population of swarm were detected. The results showed that the dose of complex vitamins in overwintering diet of Apis cerana cerana in syrup should be lower than 0.08 mg/kg and that of complex minerals should be between 0.95 and 1.89 mg/kg when there was no natural fodder-honey.[Chinese Journal of Animal Nutrition, 2010,22(6):1625-1629]
