Eighteen of 91 seven- to nine-month-old Belgian white and blue double-muscled male fattening cattle developed typical signs of shipping fever. They were all injected intramuscularly once a day for three days with 5 mg/kg of enrofloxacin, and in addition nine selected at random were injected intramuscularly five times at 12 hour intervals with 0.1 mg/kg of(More)
This study was to investigate whether the monofrequency forced oscillation (MFO) technique could be accurately used for pulmonary function testing in calves. The airflow resistance measured by this technique was compared to the resistance measured by the classical reference method by an in vitro study, using an artificial lung model, and by an in vivo(More)
Eighteen Belgian white and blue double-muscled calves suffering from the acute respiratory distress syndrome were studied. Fifteen of the calves inhaled ipratropium bromide (0.6 mg) four times a day for three to four days whereas the other three control calves inhaled sterile 0.9 per cent saline. All the animals were injected with ceftiofur sodium (1(More)
Parameters derived from the non-invasive and simple monofrequency forced oscillation technique were compared with classical parameters of ventilatory mechanics in order to assess its usefulness for the investigation of pulmonary function in calves. To facilitate this comparison, theoretical derivations were coupled with in vitro measurements, using an(More)
A hyperspectral endmember detection and spectral unmixing algorithm that finds multiple sets of endmember distributions is presented. If endmembers are represented as random vectors, then they can be characterized by a multivariate probability distribution. These distributions are referred to as endmember distributions. The proposed method combines the(More)
Impulse oscillometry (IOS) was compared with conventional pulmonary function techniques (using oesophageal balloon and airflow measurements). Healthy Friesian (FR) and Blue Belgian (BB) calves were examined in different conditions of extrathoracic airway resistance (physiological and vertical head position). Higher resistance values were detected in BB(More)
The Functions of Multiple Instances (FUMI) method for learning target pattern and non-target patterns is introduced and extended. The FUMI method differs significantly from traditional supervised learning algorithms because only functions of target patterns are available. Moreover, these functions are likely to involve other non-target patterns. In this(More)
During this investigation, which involved 58 Belgian White and Blue double-muscled calves affected by a naturally occurring Acute Respiratory Distress Syndrome, the clinical efficiency of a 5-HT2 receptor blockade with metrenperone (group A) was compared to the efficiency of a non-steroidal (flunixine meglumine--group B) and a steroidal (prednisolone sodium(More)
This cross-over trial involving 6 Blue Belgian double-muscled calves aimed to investigate whether ipratropium bromide inhaled alone or in combination with clenbuterol hydrochloride could prevent the dramatic clinical and pulmonary disturbances that are observed during an experimentally induced bronchoconstriction. Inhaled bronchodilators significantly(More)
