“…Comet‐tail artifacts were frequently observed in this study in healthy calves and all but 2 animals had at least 1 thoracic ultrasonographic site with this artifact. In human medicine29 as well as in previous work in cattle,16 diffuse comet‐tail artifacts have been associated with diffuse parenchymal lung diseases such as emphysema. Our study therefore suggests that these can also be found without lung consolidation or clinical score compatible with BRD.…”

“…Thoracic ultrasonography was used in this study in order to assess lesions secondary to lung infection. It has been proven to be a reliable tool to assess lung consolidation as well as the extent of lesions in calves15, 16, 18 and can be done easily in a field setting 419 However, it is important to remember that consolidated lung is not systematically associated with lung infection.…”

“…Since the 1990s, noninvasive assessment of lung parenchyma has been reported as a valuable tool to monitor thoracic lesions associated with pneumonia and pleuritis 12, 13, 14, 15, 16, 17. Thoracic ultrasonography is correlated with both radiographic15, 16 and macroscopic findings 14, 16, 18.…”

BackgroundThe diagnostic tools for bovine respiratory disease diagnosis include clinical inspection, thoracic auscultation, and ultrasonography.HypothesisThoracic auscultation and clinical examination have limitations in the detection of lung consolidation in dairy calves.AnimalsProspective cohort of 106 preweaned calves from 13 different dairy herds (10 with a history of active bovine respiratory disease (BRD) in calves and 3 without suspected BRD problems).MethodsEach preweaned calf was clinically inspected using the Wisconsin calf respiratory scoring chart (CRSC) and treatment history was noted. Systematic thoracic auscultation and ultrasonography then were performed, the latter focusing on lung consolidation. Mortality was recorded over a 30‐day period.ResultsA total of 56 of 106 calves had ultrasonographic evidence of lung consolidation. The sensitivity of thoracic auscultation to detect consolidation was 5.9% (range, 0–16.7%). Only 41.1% (23/33) of calves with consolidated lungs had been treated previously by the producers. When adding CRSC and previous BRD treatment by the producer, sensitivity of detection increased to 71.4% (40/56). The area under the receiver operating characteristics curve was 0.809 (95% CI, 0.721–0.879) for the number of areas within the lungs with consolidation and 0.743 (95% CI, 0.648–0.823) for the maximal depth of consolidation as predictors of death within 1 month after examination. These were not significantly different (P = .06).Conclusions and Clinical ImportanceThis study shows that thoracic auscultation is of limited value in diagnosing lung consolidation in calves. Ultrasonographic assessment of the thorax could be a useful tool to assess BRD detection efficiency on dairy farms.

Background In the veal calf industry, bovine respiratory disease is the main cause of morbidity and mortality. Lung ultrasonography (LUS) is an accurate technique to diagnose bronchopneumonia in calves. Due to the economic constraints faced by the industry, a screening technique able to rapidly examine large numbers of calves is required. Objective To determine if lung ultrasonography focusing on the cranial part of the thorax (1st to 2nd intercostal space (ICS) on the right and 2nd to 3rd on the left) and/or on the middle part of the thorax (3rd to 5th ICS on the right and 4th to 5th on the left) (alternative techniques) are rapid screening techniques as sensitive as LUS of the entire lung (reference technique) to identify calves with lung consolidation lesions. Methods Data on 300 veal calves aged 33.1 ± 8.0 days and weighing on average 67.5 ± 4.0 kg at LUS from two farms were analysed. Systematic LUS of the entire lung was performed on all calves and a lung consolidation score was given to different parts of the thorax. Agreements between the alternative and the reference techniques were measured by Cohen's κ, McNemar's test and weighted κ. Results Agreement between LUS focusing on the cranial + middle part or on the cranial part only of the thorax and the reference technique were almost perfect with a cutoff of 1 cm. The relative sensitivity of these two alternative techniques was high (> 93%). Conclusion Lung ultrasonography of the cranial + middle part or on the cranial part only of the thorax are quick and sensitive techniques to identify veal calves with lung consolidation lesions shortly after arrival at the facility.

The purpose of the present study was to evaluate cattle and buffaloes with respiratory disorders, determine the extent of the lesions, and assess prognosis. The results were compared with the findings determined following physical examination and at slaughter. Animals were referred to Veterinary Teaching Hospitals because of inappetance, loss of body condition, cough, dyspnea, and nasal discharges. Ultrasonographically, it was possible to detect bronchopneumonia, consolidation, pleural effusion, pulmonary emphysema, and pleuritis. It was not possible to visualize lesions located deeper within the lungs where peripheral tissue was not affected. Laboratory findings included a neutrophilic leukocytosis, γ-globulinemia, and increased activity of aspartate aminotransferase. A diagnosis of respiratory disease was made on the basis of clinical and ultrasonographic findings and confirmed in 25 cases at slaughter. Bovine ultrasonography appears to be suitable as a screening tool for detection of pathologic lung processes near the pleura. Thoracic ultrasonography allows assessment of the extent and severity of pulmonary changes so that further evaluations can be considered.
