Abstract: Myodes rufocanus as an important rodent species in the forest regions of Northeast China, has attracted increasing research attention due to its unique ecological characteristics and potential value as a laboratory animal. However, its solitary nature, high aggressiveness, and specific nutritional requirements pose significant challenges for captive breeding. Based on international rodent welfare standards, this study systematically optimized the housing environment, behavioral management, and breeding strategies for Myodes rufocanus. Experimental result demonstrated that:A mixed bedding system of corncob and wood shavings effectively controlled cage humidity while meeting nesting requirements; Individual housing significantly reduced fight-induced mortality.Dietary enrichment (Chinese cabbage, apple branches) and exercise enrichment markedly decreased stereotypic behaviors. Furthermore, subcutaneous implantation of PIT tags enabled precise individual identification. This study establishes a standardized protocol for the laboratory adaptation of Myodes rufocanus, filling a critical gap in welfare research for voles of the Myodes genus.

摘要： 棕背䶄作为我国东北林区的重要啮齿类动物,因其独特的生态习性和潜在的实验动物价值,近年来受到广泛 关注。然而,其独居性、高攻击性和特殊的营养需求使得人工饲养面临严峻挑战。本研究基于国内外啮齿类动物福利标准,系统优化了棕背䶄的饲养环境、行为管理和繁殖策略。实验结果表明,采用玉米芯与刨花混合垫料可有 效控制笼内湿度,并满足筑巢需求;单笼独居饲养能显著降低打斗死亡率;饮食丰容(白菜、苹果枝)和运动丰容能 显著减少刻板行为。此外,皮下植入PIT标签实现了个体精准管理。本研究为棕背䶄的实验动物化提供了标准化 方案,填补了属动物福利研究的空白。
