| Popis: | In this study we defined smallholders’ sheep breeding objectives using farmers’ trait preferences through a proportional-piling tool and a bio-economic model to evaluate the congruence between the two breeding objectives. We took Menz sheep of Ethiopia as a case study. Multinomial logistic regression analysis showed that there were no statistically significant differences among weights allocated by farmers to growth rate, survival and lambing interval, which formed the high priority traits for Menz farmers. The likelihood of farmers attaching more weight to these three traits was significantly higher than they do to 6-month weight, mature weight, fleece weight and litter size (odds ratio = 1.16 to 2.32, P |
