Article Synopsis
- Bovine respiratory disease (BRD) significantly impacts calf mortality in Ireland, with one-third of deaths in 1-to-5 month-old calves attributed to it, revealing limitations in clinically diagnosing BRD based solely on observable respiratory signs.
- A study involving 53 male dairy calves found that while 43% showed clinical BRD symptoms, 64% had detectable lung lesions through ultrasonography, often preceding clinical signs by over ten days.
- Despite the presence of BRD, overall growth rates (average daily weight gain) did not significantly differ between calves with and without clinical signs, but those with severe lung lesions experienced reduced growth compared to healthy calves.
