The new technology of silkworm (Bombyx mori L.) artificial feed breeding has many characteristics and advantages. This study assessed silkworm rearing with mulberry leaf at all instars (MF) as the control, and used metabolomics to explore the differences in haemolymph metabolism of fifth instar silkworms under two modes of rearing with an artificial diet at all instars (AF) and rearing with an artificial diet during first to third instars and mulberry leaf during the fourth and fifth instars (AMF). The results show that, compared with silkworms of the MF group, the amount and fold change of various metabolites were higher in the haemolymph of AF group silkworms, and the metabolism of amino acids and uric acid, carbohydrates, lipids, and vitamins were changed. These changes may be the reasons for the poor performance of the AF silkworms. However, the amount and fold change of the various metabolites of silkworms in the AMF group were lower, and some metabolic pathways were more active. The amount of material and energy supply were greater. These changes could explain the high efficiency growth of body weight of silkworms after the conversion from artificial diet rearing to mulberry leaf rearing. These findings provide an important theoretical basis for the optimisation of artificial diet rearing technology for silkworms.

桑叶和两种人工日粮饲养方式下家蚕（Bombyx mori L.）血淋巴代谢组学差异

蚕新技术（Bombyx mori L.)人工饲料养殖有很多特点和优势。本研究以桑叶全龄（MF）养蚕为对照，利用代谢组学研究全龄人工饲粮（AF）和人工饲料养蚕两种模式下五龄蚕血淋巴代谢的差异。第一到第三龄的人工饲料和第四和第五龄的桑叶（AMF）。结果表明，与MF组家蚕相比，AF组家蚕血淋巴中各种代谢物的数量和倍数变化较高，氨基酸和尿酸、碳水化合物、脂类和维生素的代谢发生变化。这些变化可能是AF蚕表现不佳的原因。然而，AMF组家蚕各种代谢产物的量和倍数变化较低，部分代谢途径更为活跃。物质和能源供应量更大。这些变化可以解释蚕从人工饲料饲养转为桑叶饲养后体重的高效增长。这些发现为家蚕人工日粮饲养技术的优化提供了重要的理论依据。
