Measuring Heterogeneous Preferences for Cattle Traits among Cattle‐Keeping Households in East Africa
利用肯尼亚和埃塞俄比亚506户养牛家庭的选择实验数据，通过混合logit和潜类别模型分析农户对牛只性状的偏好差异，发现种植系统重视牵引力和抗锥虫病，而牧区系统关注畜群增长，为针对性育种政策提供依据。
Abstract This study employs mixed logit and latent class models to examine preferences for cattle traits with a focus on heterogeneity among cattle keepers, using choice experiment data of 506 cattle‐keeping households in Kenya and Ethiopia. The findings indicate the existence of preference heterogeneity based on cattle production systems. Highly valued cattle traits for the cropping systems include traction fitness and trypanotolerance, while traits associated with herd increase are considered important in pastoral systems. Considering heterogeneity within population segments provides a framework for adapting breeding policy interventions to specific producer segments, by integrating preferred traits in a breed improvement program.
