摘要

Cull dairy cows are regularly removed from dairy herds and enter the marketing system which often involves transportation to public auction markets and then to an abattoir. Many cull dairy cows are removed from the herds because of health reasons andtheir ability to withstand transportation may vary. Moreover, dairy producers lack feedback about potential transport delays and the condition of the cows throughout the transport continuum. The objectives of this study were (1) to follow cull cows fromfarm to abattoir, (2) to monitor changes in the cows' condition, and (3) to record transport delays. From May 2017 to March 2018, data were collected from 20 dairy farms, 2 auction markets and at 6 abattoirs in British Columbia, Alberta, and the USA. Thedairy farms were visited regularly before cows were shipped and a researcher scored the animals for body condition (BCS; 5-point scale), lameness (5-point scale) and udder condition (3-point scale). Trained assessors at the abattoirs also assessed cows'condition at arrival.
