This research surveyed over 784 Chinese consumers in Shanghai and Nanjing in 2001 and 2002, evaluating their preferences for livestock product attributes using ordered-probit models and factor analyses. Empirical results confirm the heterogeneity of Chinese livestock retail markets and suggest...

Cattle consuming tall fescue pastures infected with the endophyte Neotyphodium coenophialum often suffer physiological disorders that reduce animal performance. One solution is to replace endophyte-infected tall fescue pastures with an endophyte-free mixture. A benefit-cost analysis was...

Based on a consumer survey with over 700 observations, Chinese consumer preferences of livestock product attributes were evaluated using factor analysis and probit models. Regional and time differences were examined. Empirical results provide U.S. exporters with valuable information on China's...
