摘要

本研究旨在确定埃塞俄比亚西北部农民对土著牛的育种目标和性状偏好。采用多阶段有目的随机抽样技术选择研究区和小农。通过对320户家庭的结构化问卷调查、个人观察和焦点小组讨论收集所需数据。资料分析采用χ2检验、最小二乘法、排序指数等统计方法。最小二乘均值分析显示差异(p < 0.001),平均畜群规模为10.9头。从排名指标结果来看,产奶量(0.35)和役力(0.25)是农民主要的养牛目的/目标。配种方式的χ2检验结果显示差异有统计学意义(p < 0.001), 63.8%的农户采用对照配种。根据排名指数结果,体型大(0.35)、颜色(0.26)和良好的牵引力(0.18)是选择种牛的最重要特征。高产奶量(0.4)、颜色(0.19)、体型大(0.16)和犊牛生长(0.13)是奶牛选择的首选性状/标准。在本研究中,优先考虑农民的性状偏好和育种目标对于育种计划的设计和实施至关重要。

Breeding objectives and selection criteria of farmers keeping indigenous cattle populations in north-west Ethiopia
This study was conducted to identify farmers’ breeding objectives and trait preferences for indigenous cattle in north-west Ethiopia. Multistage purposive and random sampling techniques were used to select study districts, and smallholder farmers. The required data were collected through structured questionnaires from 320 households, personal observations, and focus group discussions. The chi-square (χ2) test, least squares mean, and ranking index were statistical methods used for data analysis. The least squares mean analysis showed a difference (p < 0.001) and the mean herd size was 10.9 heads. Based on ranking index results, milk production (0.35) and draught power (0.25) were the main cattle production purpose/objectives of farmers. The chi-square (χ2) test results of mating practices showed a significant difference (p < 0.001) and 63.8% of farmers used controlled mating. According to the ranking index result, large body size (0.35), colour (0.26), and good traction (0.18) were considered the most important traits in selecting a breeding bull. High milk yield (0.4), colour (0.19), large body size (0.16), and calf growth (0.13) were the preferred traits/criterias for cow selection. Prioritizing farmer trait preference and breeding objectives in this study was critical for the design and implementation of breeding programmes.

期刊介绍: Journal of Applied Animal Research (JAAR) is an international open access journal. JAAR publishes articles related to animal production and fundamental aspects of genetics, nutrition, physiology, reproduction, immunology, pathology and animal products. Papers on cows and dairy cattle, small ruminants, horses, pigs and companion animals are very welcome, as well as research involving other farm animals, aquatic and wildlife species. In addition, manuscripts involving research in other species that is directly related to animal production will be considered for publication.
