摘要: 本文论述了对我国畜禽品种资源保护的两种战略及依据,即被动保种战略与主动保种战略。这一研究结论是基于我国畜禽品种资源的现状与特点:即拥有丰富的品种资源(共有601个品种与类型,其中本国地方品种385个)多样化的性能与产品对世界畜牧业的贡献面临经济发展的严峻挑战以及处于变化中的品种结构等。对于那些濒于灭绝及濒危中的品种,可采取被动保种的办法而对于尚未濒危但有潜在危险的大多数地方品种,则应采取主动保种的办法,将保种与开发相结合。并在主动保种方面提供了滩羊与湖羊保种研究中的两个实例以做说明。

Abstract: This paper expresses two conservation strategies, the passive conservation and the active conservation, for the domestic animal and fowl genetic resources in China. The study is based on the current status of these resources and their characteristics: rich in breeds, varieties, and types (the total number is 601, of them 385 are local breeds) diversified traits and production the contribution to world animal production facing serious challenges of economic development, and the breed structure. In process of change, for the relics and endangered breeds the passive conservation strategy should be adopted. For other breeds, the active conservation strategy should be adopted, and the reasonable combination of conservancy and development should be done. Two examples, the active conservation of Tan sheep and Hu sheep, are presented in this paper.

Key words: domestic animal and fowl genetic resources, active conservation of breeds, passive conservation of breeds
