Abstract

Commercial layer and indigenous chicken farming in Nairobi and associated activities in the egg value chains are a source of livelihood for urban families. A value chain mapping framework was used to describe types of inputs and outputs from chicken farms, challenges faced by producers and their disease control strategies. Commercial layer farms were defined as farms keeping exotic breeds of chicken, whereas indigenous chicken farms kept different cross breeds of indigenous chicken. Four focus group discussions were held with producers of these chickens in peri-urban area: Dagoretti, and one informal settlement: Kibera. Qualitative data were collected on interactions between farmers, sources of farm inputs and buyers of poultry products, simple ranking of production challenges, farmers' perception on diseases affecting chicken and strategies for management of sick chicken and waste products. Value chain profiles were drawn showing sources of inputs and channels for distribution of chicken products. Production challenges and chicken disease management strategies were presented as qualitative summaries. Commercial layer farms in Dagoretti kept an average of 250 chickens (range 50-500); while flock sizes in Kibera were 12 chickens (range 5-20). Farms keeping indigenous chicken had an average of 23 chickens (range 8-40) in Dagoretti, and 10 chickens (range 5-16) in Kibera. Commercial layer farms in Dagoretti obtained chicks from distributors of commercial hatcheries, but farms in Kibera obtained chicks from hawkers who in turn sourced them from distributors of commercial hatcheries. Indigenous chicken farms from Dagoretti relied on natural hatching of fertilised eggs, but indigenous chicken farms in Kibera obtained chicks from their social connection with communities living in rural areas. Outlets for eggs from commercial layer farms included local shops, brokers, restaurants and hawkers, while eggs from indigenous chicken farms were sold to neighbours and restaurants. Sieved chicken manure from Dagoretti area was fed to dairy cattle; whereas non-sieved manure was used as fertilizer on crops. Production challenges included poor feed quality, lack of space for expansion, insecurity, occurrence of diseases and lack of sources of information on chicken management. In Kibera, sick and dead chickens were slaughtered and consumed by households; this practice was not reported in Dagoretti. The chicken layer systems contribute to food security of urban households, yet they have vulnerabilities and deficiencies with regard to disease management and food safety that need to be addressed with support on research and extension.

摘要

内罗毕的商业蛋鸡养殖和土鸡养殖以及鸡蛋价值链中的相关活动是城市家庭的生计来源。采用价值链映射框架来描述养鸡场的投入和产出类型、生产者面临的挑战及其疾病控制策略。商业蛋鸡场被定义为饲养外来品种鸡的农场,而土鸡场则饲养不同杂交品种的土鸡。在城市周边地区达戈雷蒂以及一个非正式定居点基贝拉,与这些鸡的生产者进行了四次焦点小组讨论。收集了关于农民之间的互动、农场投入来源和家禽产品买家、生产挑战的简单排名、农民对影响鸡的疾病的看法以及病鸡和废弃物管理策略的定性数据。绘制了价值链概况图,展示了投入来源和鸡肉产品的分销渠道。生产挑战和鸡病管理策略以定性总结的形式呈现。达戈雷蒂的商业蛋鸡场平均饲养250只鸡(范围为50 - 500只);而基贝拉的鸡群规模为12只(范围为5 - 20只)。达戈雷蒂饲养土鸡的农场平均有23只鸡(范围为8 - 40只),基贝拉为10只(范围为5 - 16只)。达戈雷蒂的商业蛋鸡场从商业孵化场的经销商处获取雏鸡,但基贝拉的农场从小贩处获取雏鸡,而小贩又从商业孵化场的经销商处采购。达戈雷蒂的土鸡场依靠受精卵的自然孵化,但基贝拉的土鸡场通过与农村地区社区的社会关系获取雏鸡。商业蛋鸡场的鸡蛋销售渠道包括当地商店、经纪人、餐馆和小贩,而土鸡场的鸡蛋则卖给邻居和餐馆。达戈雷蒂地区筛过的鸡粪喂给奶牛;未筛过的粪便用作农作物肥料。生产挑战包括饲料质量差、缺乏扩张空间、不安全、疾病发生以及缺乏养鸡管理信息来源。在基贝拉,生病和死亡的鸡被家庭宰杀并食用;达戈雷蒂未报告这种做法。蛋鸡养殖系统有助于城市家庭的粮食安全,但在疾病管理和食品安全方面存在脆弱性和不足,需要通过研究和推广支持来加以解决。
