The purpose of this study was to assess the effectiveness of an evaluation form designed to aid dairy producers to evaluate cows being culled, and to prevent the transport of cows that may be unable to withstand the stress of transport. The objectives of this pilot project were to educate dairy producers about Canadian transport requirements; have producers use the evaluation form to prevent the transport of unfit cows; assess the efficacy of the form; and to encourage the use of standard operating procedures for evaluating cull cows. A total of 16 practicing bovine veterinarians and 54 Ontario dairy producers participated in this study. Veterinarians and producers were sent a pre-study survey to assess their knowledge and attitudes regarding culling cows, 10 cull cow evaluation forms, 2 scoring keys (for both body condition and lameness), and later, a post-study survey, to determine whether their knowledge and attitudes had changed. Veterinarians provided training on proper use of the evaluation form, and the producers completed an evaluation form for every cow they culled from the herd from January to August 2017. The evaluation form included space to record the cow’s body temperature, body condition score, gait, CMT score, last drug treatment date, last milking date, removal date and destination. Data analysis is underway to determine the efficacy of the form and opportunities for form improvement. SAS software was used to perform a Wilcoxon signed rank test to determine whether the responses given by participants differed between completed pre- and post-study surveys. Preliminary data analysis indicated that there was a tendency for producers to report higher confidence in their ability to assess cows before transport after using the evaluation form (P = 0.06). There was an increase in veterinarian’s reported confidence in their ability to help their dairy clients assess cows before transport (P < 0.05). The potential implications of this research project include providing producers with an effective tool to help assess their cattle before transport, and to encourage greater veterinary involvement with their clients.
