The main objective of this study was to investigate the effects of pollen patty with supplementation of different concentrations of curcumin-steviol glycoside complex (CSG) in (). Twelve colonies of were conducted from July 10th to August 21st for 42 days. were assigned to four dietary treatments with 3 replicates of equal size as follows: no supplementation of pollen patty (NC), supplementation of basal pollen patty (PC), supplementation of basal pollen diets + 0.04% of CSG (T1), supplementation of basal pollen diets + 0.08% of CSG (T2). The percentage of CSG was calculated based on the total weight of pollen patties. Thorax weight was significantly increased ( < 0.05) in the T2 diet compared with the NC and PC diet. There was no significant difference ( > 0.05) in pollen patties consumption among the PC, T1, and T2 diets. The T1 and T2 diets showed significantly higher ( < 0.05) honey production than the PC and NC diets. Also, the PC diet showed significantly higher ( < 0.05) honey production than the NC diet. The T2 showed significantly higher ( < 0.05) brood area than the PC and NC diets at 28 and 42 days. In addition, the PC and T1 diets showed significantly higher ( < 0.05) brood areas than the NC diet. The T1 and T2 diets showed significantly higher ( < 0.05) catalase and superoxide dismutase (SOD) 1 gene expression than the PC and NC diets. The expression of the thioredoxin reductase (Trxr) 1 gene was significantly higher ( < 0.05) in the T1 diet, and decreased in the order of the PC, T2, and NC diets. The expression of the SOD2 gene was significantly higher ( < 0.05) in the T1 diet than the PC and T2 diets and was significantly lower ( < 0.05) in the NC diet. Therefore, supplementation of CSG to pollen patty might be the ideal strategy to improve performances.
本研究的主要目的是调查补充不同浓度姜黄素-甜菊糖苷复合物（CSG）的花粉饼对（）的影响。从7月10日至8月21日对12个蜂群进行了为期42天的实验。将蜂群分为四种日粮处理，每组3个重复，每组规模相同，如下所示：不补充花粉饼（NC）、补充基础花粉饼（PC）、补充基础花粉日粮+0.04% CSG（T1）、补充基础花粉日粮+0.08% CSG（T2）。CSG的百分比是根据花粉饼的总重量计算的。与NC和PC日粮相比，T2日粮组的胸重显著增加（P<0.05）。PC、T1和T2日粮之间的花粉饼消耗量无显著差异（P>0.05）。T1和T2日粮的蜂蜜产量显著高于PC和NC日粮（P<0.05）。此外，PC日粮的蜂蜜产量显著高于NC日粮（P<0.05）。在第28天和第42天，T2的育虫面积显著高于PC和NC日粮（P<0.05）。此外，PC和T1日粮的育虫面积显著高于NC日粮（P<0.05）。T1和T2日粮的过氧化氢酶和超氧化物歧化酶（SOD）1基因表达显著高于PC和NC日粮（P<0.05）。硫氧还蛋白还原酶（Trxr）1基因的表达在T1日粮中显著较高（P<0.05），并按PC、T2和NC日粮的顺序降低。SOD2基因的表达在T1日粮中显著高于PC和T2日粮，而在NC日粮中显著较低（P<0.05）。因此，在花粉饼中补充CSG可能是提高（）性能的理想策略。
