Respiratory disease is a leading cause of death loss among US beef cattle operations and has significant lingering negative impacts on calf health, performance, and financial returns as they move through the supply chain. It can also negatively impact cowherd reproductive performance. Yet, a significant number of beef cattle operations have not adopted respiratory vaccination for calves or the breeding herd.
This analysis explores the potential reasons why some producers vaccinate their cattle and some do not, including how influential factors regarding vaccination adoption differ between calves and the breeding herd using Probit regression analysis.
Regression results indicate that, for calves, the likelihood of respiratory vaccine adoption is most influenced by herd size and the use of other vaccines. Breeding herd vaccination decisions are more complex, influenced not by herd size but rather by disease knowledge and risk perception, producer education, and cost barriers.
Herd health management education efforts through veterinarians and extension services can use these results to better target respiratory vaccination information addressing some of these barriers, improving national cattle herd health.
呼吸系统疾病是美国肉牛养殖中导致死亡损失的主要原因，并且在小牛通过供应链的过程中，对其健康、性能和经济回报有着显著且持久的负面影响。它还会对母牛群的繁殖性能产生负面影响。然而，相当数量的肉牛养殖场并未对小牛或繁殖母牛群采用呼吸道疫苗接种。
本分析探讨了一些生产者对其牛群进行疫苗接种而另一些则不接种的潜在原因，包括使用Probit回归分析研究在小牛和繁殖母牛群之间，影响疫苗接种采用的因素有何不同。
回归结果表明，对于小牛而言，采用呼吸道疫苗的可能性受牛群规模和其他疫苗使用情况的影响最大。繁殖母牛群的疫苗接种决策更为复杂，不受牛群规模影响，而是受疾病知识和风险认知、生产者教育以及成本障碍的影响。
通过兽医和推广服务进行的牛群健康管理教育工作可以利用这些结果，更好地针对呼吸道疫苗接种信息来解决其中一些障碍，从而改善全国牛群的健康状况。
