摘要

在埃塞俄比亚奥罗米亚州贝尔区对本地鸡种群的生产和繁殖性能以及小农的性状偏好进行了研究,以评估研究地区本地鸡种群的生产和繁殖性能以及农民的性状偏好。这项研究是在埃塞俄比亚东南部贝尔区的五个选定县(马达瓦拉布、德洛梅纳、贝尔贝尔、Ginnir和Sinana县)进行的。在本研究中,采用简单随机抽样技术对390户拥有土鸡种群的家庭进行了抽样。将收集到的数据进行编码并插入到Microsoft excel电子表格中,使用SAS 9.13版软件进行分析。生长速率和产蛋性状是各研究区农民/牧民首选的第一和第二选择标准。体重是所有研究区农民/牧民对雄性和雌性鸡的主要性状偏好。土种公鸡初次交配和产蛋的平均年龄分别为4.30±0.1和4.50±0.1个月。每只母鸡年产蛋数为4.0±0.12个,每窝产蛋数为20.18±0.66个,每只母鸡年产蛋数为20.18±0.66个。雏鸡的孵化率和成活率分别为76.25%和74.35%。研究结果表明,研究区农牧民对雄性和雌性鸡的选择标准和性状偏好不同。因此,该研究表明,有机会通过选择进行遗传改良,有必要深入研究品种特征以及农牧民性状偏好与性状经济价值的关系。

Productive and reproductive performances of indigenous chicken population and traits preference of smallholder farmers in Bale Zone, Oromia Regional State, Ethiopia
A study was conducted on productive and reproductive performances of indigenous chicken population and traits preference of smallholder farmers in Bale Zone, Oromia Regional State, Ethiopia for assessing productive and reproductive performances of indigenous chicken population and farmers traits preference in study area. The study was conducted in five selected districts (Madda Walabu, Delomena, Berbere, Ginnir and Sinana districts) of Bale zone, south east Ethiopia. For this study, a total of 390 household having indigenous chicken population were sampled using simple random sampling techniques. The collected data were coded and inserted on Microsoft excel spread sheet and analysed using SAS software version 9.13. Growth rate and egg production traits are the first and second selection criteria preferred by farmers/pastoralists across study districts. Weight is the main trait preference by farmers/pastoralist both for male and female chicken across all study districts. The average age of indigenous cockerels and pullets at first mating and laying was 4.30 ± 0.1 and 4.50 ± 0.1 months, respectively. The number of clutches per hen and eggs per clutch and total eggs produced per hen per year were 4.0 ± 0.12, and 20.18 ± 0.66 eggs, respectively. The hatchability and survival rate of chicks were 76.25 and 74.35%, respectively. The result of study indicated that farmers/pastoralists in study area were practices different selection criteria and trait preference both for male and female chicken. Therefore, the study suggested that there is an opportunity for genetic improvement through selection and there is a need of in-depth breed characterization and the relationship of trait preference of farmers/pastoralists with economical values of the traits.
