The purpose of this study was (1) to evaluate the technical and methodological problems associated with invasive haemodynamic measurements in unsedated cattle; (2) to assess the reproducibility of such measurements both within and between days; and (3) to compare the values with those previously reported. Twenty-one healthy calves, aged from 5.5 to 12 months, were studied. The central venous, the right ventricular, the pulmonary arterial, the pulmonary capillary wedge and the systemic arterial pressures were obtained by means of fluid-filled catheters, and the cardiac output was measured by the thermodilution technique. The heart rate, the stroke volume, the pulmonary and systemic vascular resistances and the pulmonary and systemic ventricular workloads were calculated. An adverse reaction, consisting of severe pulmonary hypertension, tachycardia, tachypnoea and transient weakness, occurred in 7 calves during the catheterization procedures. Such a reaction might be due to a local reflex induced by stimulation of mechano-receptors by the catheter tip. It should be avoided by reducing the manipulation of the catheter as much as possible and by inflating the tip of the balloon when moving it forwards. A comparison of the vascular pressures with those previously reported was difficult because of methodological or technical limitations, such as, for instance, a lack of standardization of the baseline. The reproducibility of the haemodynamic measurements obtained was satisfactory, in contrast to previous studies performed in conscious animals. This was attributed to our animals being better trained to the experimental conditions and emphasizes the importance of reducing mental stress in obtaining reliable haemodynamic measurements in unsedated and potentially uncooperative animals.

This study was carried out to compare the changes in plasma cortisol concentration produced by 5 different types of exercise, transportation and ACTH administration. Venous blood was analysed for cortisol concentration before and after each stimulus. The types of exercise were show jumping (n=28), cross country phase of a three-day event (n=32), trot race (n=9), gallop race (n = 10) and endurance ride (n=8). The response following the intravenous injection of synthetic ACTH (200 µg) in 6 of the event horses was determined. The ACTH test was carried out one week after competition. In 5 horses, the response to road transport of one hour was studied. All stimuli, except transportation produced a significant increase in plasma cortisol concentration. The endurance ride produced the largest increase and the show jumping the smallest. ACTH administration resulted in a 164% rire in plasma cortisol. Il was concluded that I) the degree of increase in plasma cortisol concentration appeared to reflect both intensity and dotation of workload; endurance ride appeared to be the most exhaustive and show jumping the least; 2) there was a correlation (r2=0.82) between the individual cortisol response to cross country exercise and to exogenous ACTH in the saure horses and 3) there was an important individual effect on transport-induced cortisol changes.

Changes in heart rate (HR), plasma lactate (LA) and some other blood parameters were studied in 16 healthy show jumping horses participating in the Belgian Junior Championship. Venous blond was collected from each horse before and immediately after competing and was analysed for packed cell volume (PCV), LA, plasma cortisol, blood glucose (GLU), total plasma protein bicarbonate ions and serum levels of lactate dehydrogenase, creatine kinase, aspartate aminotransferase and gamma glutamyl transferase (GGT). A HR recorder placed under the saddle continuously recorded HR from the warm-up tu 5 min after the course in 10 horses. Show jumping induced a significant increase in all parameters, except GLU, which decreased significantly, and GGT which remained unchanged. Resting values of LA and HR were 0.43±0.05 mmol I-1 and 44.7±2.9 beau min-1 respectively. Post-exercise LA reached a mean value of 8.7±0.5 mmol I-1, while HR rose to a peak of 189.2±3.5 beau min-1 during Ihe course. The results of the present study demonstrated that, although the speed and duration of such an exercise are low, show jumping represents severe exertion which requires some anaerobic metabolism.

The changes occurring in breathing mechanics of exercising ponies when heliox is substituted for air are reported. Respiratory airflow, tidal volume (VT) and transpulmonary pressure (Ptp) were simultaneously measured in 5 healthy ponies (255 ± 15 kg) at rest (breathing air) and while they exercised for 6 min on a treadmill. During exercise they first breathed air (2 min), than heliox (2 min) and then air again (2 min). Tidal volume (VT), respiratory rate (fR), minute volume (VE), maximum Ptp changes, total pulmonary resistance (RJ, mechanical work of Breathing per liter (Wrm l'), mechanical work per min (Wrm), dynamic compliance and pulmonary inertance were calculated. Heliox breathing significantly increased f,, and VE while VT remained unchanged. RL was reduced by 50% of lis "air value", Wrm I-' decreased, while Wrm remained unchanged. Pulmonary inertance dropped to 30% of its "air value". These observations suggest that in ponies, turbulent resistance and pulmonary inertance could be mainly responsible for the increases of RL and Wrm 1' during exercise [less ▲]
