Proportion of cattle treated at least once for BRD and/ or succumbed to BRD during the first 120 d of the feeding period for beef and dairy-type cattle. These percentages represent unadjusted proportions. The asterisks represent the statistical test significance level as follows: “**” 0.01, “***” 0.001. BRD, bovine respiratory disease; Tx, treatment. (A) Beef morbidity proportion: 265/2,055 DNPS; beef mortality proportion: 23/2,055 DNPS; dairy morbidity proportion: 73/769 DNPS; dairy mortality proportion: 6/769 DNPS. Morbidity X2 (1, n = 2,428) = 6.15, p = 0.0132; mortality X2 (1, n = 2,428) = 0.63, p = 0.4264. (B) BRD-treated beef mortality proportion: 14/265; non-BRD treated beef mortality proportion: 9/1,790; BRD-treated dairy mortality proportion: 5/73; non-BRD treated dairy mortality proportion: 1/696. Beef X2 (1, n = 2,055) = 48.04, p < 0.001; dairy Fisher Exact (1, n = 769) = 35.27, p < 0.001.
