Abstract：
Young workers, i.e., nurse honey bees, synthesize and secrete royal jelly to feed the brood and queen. Since royal jelly is a protein-rich substance, the quality of royal jelly may be influenced by the consumption of feed with varying protein content. We tested whether honey bee (Apis mellifera) colonies compensates for the nutritional quality to produce royal jelly by feeding different pollen patties made of oak or rapeseed pollen. After harvesting royal jelly, we examined the chemical composition including proximate nutrients, amino acids, proteins, fatty acids, and minerals of royal jelly samples obtained from two treatments. The results revealed that pollen patties with different nutritional levels did not influence the nutritional composition except for the crude fat. The levels of 10-HDA, which serves as an indicator of the royal jelly quality, showed no significant difference between the oak and rapeseed treatments, with values of 1.9 and 2.1 g/100 g, respectively. However, we found some differences in the protein intensity, particularly the MRJP3 precursor, MRJP3-like, and glucose oxidase. This study suggests that honey bees may have mechanisms to compensate for nutritional standards to meet the brood\'s and queen\'s nutritional requirements during bee pollen collection, preserving bee bread and royal jelly secretion.
摘要：
年轻的工人,即，哺乳蜜蜂，合成并分泌蜂王浆来喂养育苗和女王。由于蜂王浆是一种富含蛋白质的物质，蜂王浆的质量可能受到不同蛋白质含量的饲料消耗的影响。我们测试了蜜蜂（Apismellifera）菌落是否通过喂食橡木或油菜籽花粉制成的不同花粉肉饼来补偿生产蜂王浆的营养质量。收获蜂王浆后,我们检查了化学成分，包括最接近的营养素，氨基酸,蛋白质，脂肪酸，和从两种处理中获得的蜂王浆样品的矿物质。结果表明，不同营养水平的花粉馅饼除了粗脂肪外，对营养成分没有影响。10-HDA的水平，作为蜂王浆质量的指标，显示橡木和油菜籽处理之间没有显着差异，值为1.9和2.1克/100克，分别。然而,我们发现蛋白质强度有一些差异，特别是MRJP3前体，像MRJP3一样，和葡萄糖氧化酶.这项研究表明，蜜蜂可能有机制来补偿营养标准，以满足蜂鸟和蜂王在蜂花粉采集过程中的营养需求，保存蜜蜂面包和蜂王浆分泌物。
