摘要

本研究在贡达尔北部进行,以表征城市条件下的乡村鸡生产系统。采用横断面研究方法,于2010年11月至2011年4月期间,采用问卷调查和简单随机抽样的方法,对100户家庭进行调查。鸡的主要生产目标是创收、家庭消费和替换鸡群。养鸡的大部分活动都是由妇女来完成的。平均鸡群规模为10.44只,范围为2 ~ 18只。大多数的鸡晚上都在一个隔离的封闭鸡舍里休息。研究区鸡主要通过食腐获取饲料资源,补充饲料很少。研究区鸡群死亡的主要原因是疾病(47%)、捕食(22%)和管理不善(31%)。据答复者说,其禽群经常出现的常见疾病症状是水样和淡黄色腹泻、闭眼、低垂头、发病率高、抑郁、羽翼下垂、打喷嚏或咳嗽、流鼻涕、头颈扭曲、食欲不振和集体死亡。当地母鸡平均产蛋数为11.53个/只/窝,本试验的孵化率为87.29%,范围为57.1% ~ 100%。研究村家禽生产最主要的制约因素是疾病(第1位)、捕食者(第2位)、补充饲料短缺(第3位)、家禽住房问题(第4位)和缺乏兽医卫生服务(第5位)

Characterization of Urban Poultry Production System in Northern Gondar, Amhara Regional State, Ethiopia
The study was conducted in Northern Gondar to characterize the village chicken production system under urban condition. A cross sectional type of studies were conducted to collect data from November 2010 to April 2011 using questionnaire survey and a simple random sampling techniques, 100 households were included in the survey. The main production objectives of chicken were income generation, household consumption and replacement of the flock. And most of the activities in chicken rearing were carried out by women. The average flock size was 10.44 chickens with a range of 2-18 birds. Most of the birds rested at night in a separated confined chicken house. Chickens in the study area were getting their major feed resources through scavenging with little supplementary feed provision. The major causes of losses of chicken in the study area were disease (47%), predation (22%) and mismanagement (31%). According to respondents, the common signs of disease frequently occurred in their flock were watery and yellowish diarrhoea, closing of eyes, head hangs down, high level of morbidity, depression, droppings of wings, sneezing or coughing, nasal discharge, twisting of head and neck, loss of appetite and mass death. The average number of eggs laid by local hen was 11.53eggs/hen/clutch and the hatchability percentage observed in this study was 87.29 %, which ranged from 57.1%-100%. The most important constraints of poultry production in the study villages were disease (1 st ), predators (2 nd ), shortage of supplementary feeds (3 rd ), poultry housing problem (4 th ) and lack of veterinary health services (5 th
