Table 2.
Health data (rectal temperature, respiratory rate per minute, serum haptoglobin concentration) in feedlot steers selected as bovine respiratory disease (BRD) cases (n = 35) or pen‐matched healthy controls (n = 35) by pen checkers
| BRD (n = 35) | Control (n = 35) | |||
|---|---|---|---|---|
| Mean (±SD) | Median (Q1–Q3) | Mean (±SD) | Median (Q1–Q3) | |
| Rectal temperature (°F) | 105.3a (0.9) | 105.3 (104.9–106.2) | 102.7b (1.1) | 102.8 (102.2–103.4) |
| Respiratory rate/min. | 46 (5) | 46a (42–50) | 34 (5) | 32b (30–37) |
| Serum haptoglobin (g/L) | 1.49 (0.68) | 1.47a (1.03–1.89) | 0.37 (0.48) | 0.18b (0.13–0.34) |
Q1, 25th percentile; Q3, 75th percentile; SD, Standard deviation.
Within a row, means or medians without a common superscript differed (P < .05).
