| Popis: | Disbudding and dehorning dairy calves is very common, despite the introduction of polled genetics to most dairy breeds. Appropriate pain-control practices for these procedures affect both calf welfare and public perception of the dairy industry. Previously published work has shown that North American dairy producers have not widely adopted use of these medications for disbudding or dehorning. However, since the last published work examining these practices in Canada, changes regarding awareness, availability, and future requirements for pain control have occurred in the industry. With this in mind, online and telephone surveys of both veterinarians (n=238) and dairy producers (n=603) in Ontario, Canada, were conducted in the fall of 2014 with a goal of describing current disbudding and dehorning practices and examining factors associated with the adoption of pain control use. Approximately three-quarters of dairy producers reported performing disbudding or dehorning themselves, whereas the remainder used a veterinarian or technician. Almost all (97%) of the veterinarians surveyed reported using local anesthetic, 62% used sedation, and 48% used a nonsteroidal anti-inflammatory drug. Producer use of local anesthetic was 62%, 38% used sedation and 24% used a nonsteroidal anti-inflammatory drug. Seventy-eight percent of veterinarian disbudding or dehorning was done before 8wk of age, whereas 64% of dairy producers performed this procedure before 8wk of age. Seventy-two percent of veterinarians and 63% of producers reported changing their disbudding or dehorning practices over the past 10 yr; of producers that changed their practices, 73% cited their herd veterinarian as influential. The use of pain control described in these surveys is higher than previously reported in Ontario. Identification of factors associated with best practices, or the lack of adoption of these practices, may help veterinarians target appropriate educational opportunities for their dairy clients. |
