Indigenous breeding practices of the farmers and the livestock production system form the bases for designing community-based breeding programs. The aim of this study was to characterize production system and examine breeding practices of the indigenous goat farmers in Hai district in Northern Tanzania to determine their relevance in establishing a community-based breeding program in the area. A cross-sectional survey was conducted in which information was collected from 160 households randomly selected from 6 villages. Average household herd was 29.2 goats with majority keeping less than 20 goats. Major reasons for keeping goats were income generation, meat and milk production. Controlled mating was practiced mainly using apron and castration. Castration was practiced using traditional methods to control breeding and improve meat quality. Farmers in the study area had large goat flocks and a small buck to doe ratio. Farmers do not have a good understanding of inbreeding and its negative effects but practise other good breeding methods which could impact the productivity of their animals. Diseases and feed shortages were the main constraints to production. Opportunities exist for a community-based breeding program to genetically improve goat productivity.
农民的本土养殖实践和畜牧业生产系统为设计基于社区的养殖计划提供了基础。本研究旨在描述坦桑尼亚北部 Hai 区的本土山羊养殖户的生产系统和养殖实践，以确定在该地区建立基于社区的养殖计划的相关性。本研究采用横断面调查，从 6 个村庄中随机抽取 160 户家庭收集信息。平均每户家庭有 29.2 只山羊，大多数家庭饲养的山羊少于 20 只。饲养山羊的主要原因是为了获得收入、生产肉和奶。配种主要使用围裙和去势来控制。去势是用传统的方法来控制繁殖和提高肉质。研究区的农民有大量的山羊群和较小的公母比例。农民对近亲繁殖及其负面影响了解甚少，但他们确实采用了其他一些可能影响动物生产力的良好养殖方法。疾病和饲料短缺是生产的主要限制因素。有机会通过基于社区的养殖计划来提高山羊的生产力。
