摘　　要：保护动物品种的多样性,不仅对维护家畜的环境适应能力来说是非常关键的,还关系到未来动物生产模式的建立和完善。调查结果表明,现在世界山羊育种形势呈现一个矛盾的现象:一方面,发达国家通过完善的选育组织对山羊的乳用、肉用及毛用性能进行改进;另一方面,在一些落后的地方,山羊的产品还都用于农牧民的自身消耗。当前山羊育种情况如下,少数山羊经过了充分的选育过程并具有某些特点和特性;而大多数山羊尚未经过系统、完善的选育。通过分析山羊选育的现状,作者提出了一些建议,可以更有效的开发这一物种的遗传潜质。The preservation of the biodiversity of animal breeds is the key to maintain the ability of animal production to adapt to the changing environment.A global overview of goats is showing a contradictory situation： on one hand,small but well organised sectors have developed in a few countries for milk,meat and fibre production;on the other,most of the goats are mostly still used for auto consumption of milk,meat and fibres in village herds.The present goat genetic situation includes a small number of selected and well characterised breeds for milk,meat and fibres and a majority of not well defined populations and local breeds,generally without selection schemes and organisation.After having observed that in many cases,this report concludes by some proposals to express with more efficiency the genetic potentiality of this interesting species.
