Cow-calf producers in western Canada were surveyed in June 2010 regarding calf-hood diseases and veterinary service usage; 310 producers responded. Use of veterinary services, particularly herd-health related services, increased with herd size as did neonatal diarrhea and clostridial vaccine usage. Administration of clostridial vaccines to pregnant dams before calving was associated with a reduction in neonatal diarrhea treatments; however, there was no association between neonatal diarrhea vaccine usage and a reduction in diarrhea treatments. Producers with > 220 breeding females were more likely than those with < 85 breeding females to seek veterinary advice regarding treating sick calves, have a veterinarian necropsy dead calves, have a veterinarian pregnancy check their bred females, and evaluate their herd bulls for breeding soundness.
2010年6月，对加拿大西部的奶牛养殖户就犊牛疾病和兽医服务使用情况进行了调查；310名养殖户做出了回应。兽医服务的使用，尤其是与畜群健康相关的服务，以及新生犊牛腹泻和梭菌疫苗的使用，都随着畜群规模的增加而增加。在产犊前给怀孕母牛接种梭菌疫苗与新生犊牛腹泻治疗次数的减少有关；然而，新生犊牛腹泻疫苗的使用与腹泻治疗次数的减少之间没有关联。拥有超过220头繁殖母牛的养殖户比拥有少于85头繁殖母牛的养殖户更有可能就治疗患病犊牛寻求兽医建议、让兽医对死亡犊牛进行尸检、让兽医对怀孕母牛进行妊娠检查以及评估其种公牛的繁殖健全性。
