摘要

本研究的主要目的是描述卡法地区本地鸡种群的生产系统、生产性能和相关制约因素。从Kaffa区的10个县中,根据其土鸡种群的潜力和可及性有目的地选择了3个县。从每个农村鸡舍中有意选择至少拥有五只成熟土鸡的家庭。然后,使用半结构化的问题器从300个有目的选择的家庭中收集了定性和定量变量的数据。结果表明,大多数受访者为女性(71.1%),其中56%为文盲。每户平均家庭人数为5.86人。农户养鸡主要集中在厨房(60.7%)和主房(30.7%)。玉米(55.7%)和高粱(20.3%)是农户提供的主要饲料补充物。平均鸡群规模、初蛋龄(月)、平均蛋/母鸡/窝数(窝数)、窝数和年蛋/母鸡/年分别为8.68、6.09、12.3、3.6和44。平均孵化率为80.5%。研究区主要的生产制约因素是捕食(72.7%)和病害(27.3%)。常见的捕食者类型有:Buteo jamaicensis(当地称为“Gace”)、Helogale hirtula(当地称为“Shiifoo”或“Wociwoco”)、Felis silvestris(当地称为“Haallaro”)和Felis catus(当地称为“Kubbi Kullaro”),分别占54.6%、24.4%、15.5%和5.5%。有效种群规模和近交率分别为486和0.111%,表明研究区鸡群未发生近交。综上所述,目前的研究表明,文盲女性农民主要参与了食腐制度下鸡的护理和管理。食腐制度下鸡的生产性能与国家报告相当;然而,这些表现受到捕食者和疾病的影响。因此,应该对妇女进行教育和培训,以改善家庭的整体社会经济地位并使她们受益。此外,应根据捕食者和疾病控制规划,实施成功的干预策略,有效利用地方鸡种群的现有潜力。同样,在本地鸡种群被外来品种稀释之前,也应该考虑保护它们

Indigenous Chicken Production Environments, Reproductive and Productive Performances and Constraints in Kaffa Zone, South Western Ethiopia
The main objective of this study was to describe the production systems, productive performances and associated constraints of indigenous chicken populations in Kaffa Zone. From ten districts of Kaffa Zone, three districts were purposively selected based on their potential for indigenous chicken population and accessibility. From each rural kebeles those households who possess a minimum of five mature indigenous chicken were purposively selected. Then, data on both qualitative and quantitative variables were collected from 300 purposively selected households using a semi-structured questioner. The results indicated that majority of the respondent were female (71.1%) and 56% of them were illiterate. The average family size per household was 5.86. Farmers mainly keep their chickens in the kitchen (60.7%) and main houses (30.7 %). Maize (55.7 %) and sorghum (20.3 %) were the major feed supplements provided by the households. The average chicken flock size, age at first egg (months), average egg/hen/clutch (clutch size), clutch number and annual egg/hen/year were 8.68, 6.09, 12.3, 3.6 and 44, respectively. The average hatchability was 80.5%. The major production constraints were predators (72.7 %) and diseases (27.3 %) across the studied districts. The type of predators which are commonly occurring included Buteo jamaicensis locally known as “Gace”, Helogale hirtula locally known as “Shiifoo” or “Wociwoco”, Felis silvestris locally known as “Haallaro” and Felis catus locally known as “Kubbi Kullaro” accounted about 54.6, 24.4, 15.5, and 5.5 % respectively. The effective population size and rate of inbreeding were 486 and 0.111% indicating chicken populations in the study area are not exposed to inbreeding. In conclusion, the current study indicates illiterate female farmers were mainly involved in care and managing of chickens under scavenging system. The performances of chickens were comparable with the national reports under scavenging system; however, these performances were influenced by predators and diseases. Therefore, educating and training women’s should be implemented to improve the overall socio-economic status of the family and benefit them. In addition, successful intervention strategy should be carried out to effectively utilize the existing potentials of indigenous chicken populations in line with predator and disease control programs. Again, conservation of the indigenous chicken populations should also be considered before they have been diluted with exotic breeds
