摘要

2018 - 2019年,在Bahir Dar市城市和城郊地区的小规模养鸡场中,对外来鸡品种的生长、存活和产蛋性能及盈利能力进行了评估。采用半结构化问卷调查、监测和实地观察等方法收集数据。本研究共纳入33家小规模养鸡企业(30家来自城市,3家来自城郊地区)。所有问卷数据均使用SPSS Version 20进行分析。监测资料采用SAS 9.0通用线性模型(GLM)程序进行方差分析。监测结果显示,鸡的生长性能因品种和生产者的生产系统而有显著差异。城市地区22周龄沙索T44日增重(10.66±0.03 g)和总增重(1642±5.02 g)较高。6月龄白褐鸡平均产蛋量为124.8±4.10个蛋。年平均产蛋性能为239.63±4.32。所有外来鸡的总死亡率为6.5%。尽管有许多限制,小规模的鸡肉生产还是有利可图的。季节性疾病爆发、饲料短缺和住房问题是小规模鸡肉生产者面临的主要制约因素。外来鸡的生长性能和成活率较好,但产蛋量较低。因此,研究区小规模养鸡企业的管理实践有待改进。

Growth, survival and egg production of exotic chicken breeds under small scale production system in Bahir Dar City Administration, Amhara Region, Ethiopia
Growth, survival and egg production performance and profitability of exotic chicken breeds were evaluated under small-scale chicken producers in urban and peri-urban areas of Bahir Dar City from 2018 to 2019. Data were collected using semi-structured questionnaires, monitoring and field observation. Thirty-three small-scale chicken enterprises (30 from urban and three from peri-urban areas) were included in this study. All questionnaire data were analyzed using SPSS Version 20. The monitoring data was analyzed with ANOVA using the general linear model (GLM) procedure of SAS version 9.0. The monitoring result revealed that the growth performance of chicken significantly varied with respect to breeds and production systems of producers. Sasso T44 had higher daily body weight gain (10.66 ± 0.03 g) and total body weight gain (1642 ± 5.02 g) within 22 weeks of age in the urban areas. The mean egg production for Bovans Brown at the age of six months was 124.8 ± 4.10 eggs. The annual mean egg production performance of Bovans Brown was 239.63 ± 4.32. The overall mortality rate of all exotic chicken was 6.5%. Despite many constraints, small-scale chicken production was profitable. Seasonal disease outbreaks, shortages of feed and housing problems were the major constraints of small-scale chicken producers. The growth performance and survival rate of exotic chicken was promising, but the egg production was low. Therefore, the management practices of small-scale chicken enterprises in the study area should be improved.
