不同水平维生素A对意大利蜜蜂春繁阶段群势及幼虫抗氧化性的影响
Effect of Different Levels of Vitamin A on the Colony Development and Larvae Antioxidation of Apis mellifera ligustica During the Period of Spring Multiplication
摘要
Abstract
[Objective] The objective of this study is to study the effect of different levels of vitamin A on the population and larvae antioxidation of A. mellifera ligustica during the period of spring multiplication. [Method] Twenty-five colonies of honeybees (no pollen in colonies) from a local apiary were used in the study. The honeybee colonies were randomly allocated into 5 groups with 5 replicaties for each. The 5 groups of honeybees were fed with basal diet with supplementation of vitamin A at the levels of 0 (group 1), 5 000 (group 2), 10 000 (group 3), 15 000 (group 4) and 20000 IU-kg"1 (group 5), respectively. The colony development and antioxidant activities of larvae of the 5 groups were evaluated. [Result] During the period of spring multiplication, there were significant differences in colony development and feeding amounts of the groups fed with different levels of vitamin A. The colony development of group 3 was significantly faster than the control group and other experimental groups (P<0.05) at the end of trial. The antioxidant activities (T-SOD, CAT and T-AOC) of 5-day-old larvae of group 3 and group 4 were significantly higher than the control and other experimental groups (P<0.05). The content of MDA was significantly lower than the control and other experimental groups (P<0.05). Except for group 4, the workers' emergent weight of group 3 was significantly higher than the control and other experimental groups (P<0.05). [Conclusion] Optimal diet vitamin A supplementation (10 000-15 000 IU-kg-1) will increase the population of bee colony and antioxidant activities of larvae of A. mellifera ligustica during the period of spring multiplication.关键词
