To determine whether vaccinated or conditioned feeder calves sold through special auctions in Ontario commanded a premium, compared with feeder calves sold at conventional auctions, and whether various physical characteristics of the calves were associated with the sale price.
Cross-sectional study.
14,037 calves sold through conventional and special auctions at the Keady Livestock Market during the fall of 1999 and 2000.
Calves were observed as they were sold by lot in the auction ring. Lot characteristics and the price received for each lot were recorded. Multivariate analysis was used to estimate the effect of lot characteristics and sale type on price.
Information was recorded for 2,601 calf lots. Multivariate analysis indicated that various lot characteristics were associated with sale price, with 68% of the variation explained by the model. Overall, lots sold at special auctions received a premium of 0.06 dollars/lb (Canadian dollars), compared with lots sold at conventional auctions. However, the premium varied with mean body weight of the lot and year. In addition, frame size, breed, body condition score, uniformity of the lot, weaning status, mean body weight, lot size, sex, year, and sale type were significantly related to sale price.
Results suggested that producers selling calves at special auctions at this market received a premium, compared with producers selling calves at conventional auctions.
确定安大略省通过特殊拍卖出售的接种疫苗或经过调教的饲养用犊牛，与在传统拍卖中出售的饲养用犊牛相比是否能获得溢价，以及犊牛的各种身体特征是否与售价相关。
横断面研究。
1999年秋季和2000年在基迪牲畜市场通过传统和特殊拍卖出售的14,037头犊牛。
在拍卖场按批次出售犊牛时对其进行观察。记录批次特征和每批犊牛的售价。采用多变量分析来估计批次特征和销售类型对价格的影响。
记录了2,601个犊牛批次的信息。多变量分析表明，各种批次特征与售价相关，该模型解释了68%的变异。总体而言，与在传统拍卖中出售的批次相比，在特殊拍卖中出售的批次每磅（加拿大元）溢价0.06美元。然而，溢价随批次的平均体重和年份而变化。此外，体格大小、品种、身体状况评分、批次的均匀度、断奶状态、平均体重、批次大小、性别、年份和销售类型与售价显著相关。
结果表明，与在传统拍卖中出售犊牛的生产者相比，在该市场通过特殊拍卖出售犊牛的生产者获得了溢价。
