This paper describes the traditional breeding objectives and practices of West African Dwarf goat, Djallonke sheep, and N'dama cattle keepers in The Gambia and discusses the implications of these on the design of breeding-related interventions to improve livestock productivity. Data were collected via surveys implemented within three study sites in The Gambia, where traditional mixed crop-livestock smallholder farming predominates. The surveys comprised a participatory rural appraisal conducted in nine communities and a household questionnaire targeting 238 households. Livestock-keeping households were classified as 'poorer' or 'wealthier' based on the number of cattle owned. The most important objectives for keeping all species of livestock for the poorer groups (0 to 10 cattle) was 'savings and insurance', followed by 'income' and 'ceremonial/dowry' for the small ruminants and 'manure' and 'draught' for both cows and bulls. In contrast, for the wealthier group (more than 10 cattle), savings and insurance was the fourth to seventh ranked production objective (depending on species), with the most important production objectives being ceremonial/dowry for goats, income for sheep and manure for cows and bulls. An analysis of breeding practices indicated that breeding animals are selected on criteria which partially align to the breeding objectives, animals are rarely purchased for the purpose of breed improvement, knowledge of the cause and consequence of inbreeding is low and breeding decision makers may not necessarily be the livestock owner, particularly if the livestock owner is a women. Given this, it is suggested that capacity building on breeding-related issues, particularly in relation to the selection of breeding animals and specifically targeted at the different socioeconomic groups of livestock keepers, may be an appropriate, effective and relatively low-cost breeding intervention.
本文描述了冈比亚西非矮山羊、贾隆克羊和恩达马牛养殖户的传统育种目标与做法,并探讨了这些对旨在提高牲畜生产力的育种相关干预措施设计的影响。数据是通过在冈比亚三个研究地点开展的调查收集的,这些地点以传统的农牧混合小农户养殖为主。调查包括在九个社区进行的参与式农村评估以及针对238户家庭的住户问卷调查。根据拥有的牛的数量,牲畜养殖户被分为“较贫困”或“较富裕”两类。较贫困群体(拥有0至10头牛)饲养所有牲畜品种的最重要目标是“储蓄和保险”,其次是小反刍动物的“收入”和“仪式/嫁妆”以及牛的“肥料”和“役用”。相比之下,较富裕群体(拥有超过10头牛)中,储蓄和保险是第四至第七重要的生产目标(取决于牲畜品种),最重要的生产目标是山羊的仪式/嫁妆、绵羊的收入以及牛的肥料。对育种做法的分析表明,选择育种动物的标准与育种目标部分一致,很少为了品种改良而购买动物,对近亲繁殖的原因和后果了解较少,而且育种决策者不一定是牲畜所有者,特别是如果牲畜所有者是女性。鉴于此,建议针对与育种相关的问题开展能力建设,特别是关于育种动物的选择,并专门针对不同社会经济群体的牲畜养殖户,这可能是一种合适、有效且成本相对较低的育种干预措施。
