Abstract

In the framework of a genetic improvement scheme a countrywide survey of small ruminant owners was conducted in The Gambia to obtain information about the ownership pattern, reasons for keeping and especially about breeding and management practices including housing and feeding. The main results were the following: women play a major role in small ruminant production, representing 52% of the owners of sheep, 67% of the owners of goats and 43% of the owners of both sheep and goats. The average number of animals owned is quite low (about six head of sheep and goats each, out of which about three are breeding females). Most of the breeding males are born in their respective flock and there are fewer breeding bucks than breeding rams. However, there are sufficient numbers of breeding males around. Animals are mainly left free to roam around during the dry season, and are either tethered or herded in the rainy season. During night animals are housed or tied under a shelter. Supplementary feeding is not common and vaccination against Pest des Petit Ruminants (PPR) and Pasteurellosis is only partly carried out. Implications for the establishment and structure of a multiplication tier within a three tier breeding scheme, nucleus-->multipliers-->farmers are discussed.

摘要

在一项遗传改良计划的框架内,在冈比亚对小型反刍动物养殖户进行了全国性调查,以获取有关养殖模式、养殖原因的信息,特别是有关繁殖和管理实践(包括圈舍和饲养)的信息。主要结果如下:妇女在小型反刍动物养殖中发挥着主要作用,占绵羊养殖户的52%、山羊养殖户的67%以及绵羊和山羊养殖户总数的43%。每户养殖的动物平均数量相当少(绵羊和山羊各约6头,其中约3头为繁殖母羊)。大多数种公羊出生在各自的羊群中,种公山羊比种公羊少。不过,周围有足够数量的种公羊。旱季时动物主要自由放养,雨季时则拴系或放牧。夜间动物被安置或拴在遮蔽处。补充饲喂并不常见,小反刍兽疫(PPR)和巴氏杆菌病疫苗接种仅部分进行。文中还讨论了在核心群→扩繁群→养殖户的三级繁育体系中建立扩繁层级的形式和结构的相关问题。
