本研究的目的是确定和估计的相对权重分配给首选性状的土著牛人口中最占主导地位的作物-牲畜混合生产系统在埃塞俄比亚中部。选择实验的方法来引出的偏好和随机参数logit模型被用来估计的相对重要性的首选属性的土著奶牛。结果表明，生育力、抗病力和小牛活力性状至少与牛奶一样重要。奶牛的产地也是买家的一个重要属性。属性水平变化对偏好影响的模拟结果表明，生育力和抗病性对偏好的影响大于其他性状。研究结果表明，埃塞俄比亚这一地区的小农社区依赖于半自给农业，因此牲畜发展干预措施应侧重于稳定畜群结构的多种生殖和适应性特征，而不是专注于仅对商业目的重要的特征。
This research aimed at identifying and estimating the relative weight assigned to the preferred traits of indigenous cow population in the most dominant crop-livestock mixed production system in Central Ethiopia. A choice experiment approach was employed to elicit the preferences and a random parameters logit model was used to estimate the relative importance of the preferred attributes of indigenous cows. The results show that fertility, disease resistance and calf vigour traits are at least as important as milk. The location the cows are brought from is also an important attribute for buyers. Results from the simulation on the influence of changes in attribute levels showed that fertility and disease resistance affect preferences more than other traits. The findings suggest that the smallholder community in this part of Ethiopia depends on semi-subsistence agriculture and so livestock development interventions should focus on a multitude of reproductive and adaptive traits that stabilise the herd structure rather than focusing on traits that are only important for commercial purposes.
