In dogs suffering from dilated cardiomyopathy, myocardial concentrations of L-carnitine are sometimes very low. A Labrador suffering from dilated cardiomyopathy was treated with L-carnitine. The dog showed a clear and rapid clinical improvement as well as an improvement of electrocardiographic and echocardiographic indices of cardiac function. Screening by myocardial biopsy in dogs affected by dilated cardiomyopathy and in susceptible breeds is recommended. The dog had been maintained on a strict vegetarian diet. [less ▲]

A 3-month-old female mixed-breed pup was referred for evaluation and treatment of patent ductus arteriosus (PDA). Selective angiography was performed to confirm the diagnosis. A cone-shaped PDA with a large aortic base was outlined. A second selective angiographic procedure was performed to functionally close the PDA by use of thrombotic coils; complete obstruction was obtained. Twenty-four hours after the procedure, the murmur disappeared. One month later, the dog was reexamined and found to be clinically normal. [less ▲]

The acute polymyopathy in a seven-year-old German shepherd dog was attributed to the muscular hypertonia, tremors and seizures which developed during the acute phase of carbamate poisoning. After two days of generalised muscular rigidity, the dog adopted a characteristic fetal position which could be explained by the imbalance between the injuries to the extensor and flexor muscles. The polymyopathy resolved gradually over the course of a week. [less ▲]

During growth, central venous, right ventricular, pulmonary arterial, pulmonary capillary wedge, and systemic arterial pressures, heart rate, and cardiac output were repeatedly measured in 41 Friesian calves, considered as having conventional muscular conformation, and in 19 Belgian White and Blue double-muscled calves. A total of 123 and 70 recordings were collected in conventional and double-muscled calves, respectively. These circulatory indices were calculated: stroke volume, cardiac and stroke indices, pulmonary and systemic pulse pressures, pulmonary and systemic vascular resistance indices, and right and left ventricular work indices. Results indicated that systemic arterial and pulse pressures, as well as cardiac output, stroke volume, cardiac and stroke indices, and right and left ventricular work indices were significantly (P < or = 0.05 to 0.001) lower but, in contrast, pulmonary and systemic vascular resistance indices were significantly (P < or = 0.001) higher in double-muscled than in conventional calves. Right-sided vascular pressures and heart rate were similar in the 2 groups. These results indicated that global cardiac performance may be considerably poorer in double-muscled calves. Diminished cardiac performance of double-muscled calves appears to be related neither to relative bradycardia nor to reduced ventricular preload. The potential role of increased ventricular afterload or of reduced myocardial contractility in double-muscled cattle should be determined by direct measurements. [less ▲]

Two randomly distributed groups of thoroughbred horses were compared during a 12-week period for their cardio-respiratory and metabolic adjustment to strenuous exercise, training and detraining. The horses were trained following the same standardized schedule and were regularly investigated using standardized treadmill exercise tests (SET) of increasing speed. After the first SET and during the whole experimental period, a group of 6 horses received a probiotic (Bioracing) once a day while a group of 5 horses received a placebo. All other conditions were similar for both groups. During each SET, the oxygen uptake, carbon dioxide output, tidal volume (inspired volume), respiratory rate and expired minute volume were obtained using 2 ultrasonic pneumotachographs and a mass spectrometer. All the parameters were the mean of the values calculated during the last 20 s of the SET. Heart rate was continuously measured with a polar horse tester. Venous blood was sampled before and after the test and analyzed for various biochemical parameters. In both groups, training induced significant modification in most of the cardio-respiratory parameters, ie peak oxygen uptake, peak carbon dioxide output, respiratory exchange ratio, ventilation/min to oxygen-uptake ratio and oxygen-uptake to heart-rate ratio. After the 3-week detraining period, most of the values were again similar to the pre-training values in both groups. However, the training-induced modifications of most of the cardio-respiratory parameters occurred earlier and were proportionally greater in the probiotic-treated group than in the control. The respiratory coefficient decreased in the control but not in the treated group. All other parameters changed similarly in both groups. This suggests that Bioracing could modify the physiological effects of training by improving some aerobic metabolic capacities for carbohydrate utilization, but that this effect occurs only during training and not during periods of physical inactivity [less ▲]

Bovine muscle biopsies were analysed for fiber type and capillary density by the acid ATP-ase and amylase-PAS methods respectively. Samples obtained from Belgian blue double muscled (DM) calves were compared for their fibre type, size and vascularization with samples from Friesian (F) calves. The animals were sampled both at 2 and 7 months of age. Changes in histochemical composition occurring with ageing, independently of the breed, and differences related to the muscle sampled by comparing biopsies obtained from the longissimus dorsi (LD) and gluteobiceps (GB) muscles in animals of both breed were also investigated. Independently of age and muscle, fibre type I percentage and area were significantly higher in F than in DM muscles. Type IIa area was significantly larger in F than in DM, while fibre type IIb percentage and area were higher in DM. The number of capillaries/mm2 was significantly higher in F than in DM. Fibre type IIa and IIb percentage as well as the diameter of the three fibre types was significantly higher in the oldest animals. Finally, independently of age and breed, fibre type I and IIb percentages were significantly higher in LD but lower in GB. The results mainly demonstrated that Belgian blue DM muscles present a higher proportion of IIb fibres and a lower capillary supply than F muscles. [less ▲]

This study was designed to test the applicability and the reproducibility of the thermodilution method in the measurement of right ventricular ejection fraction (EF), end-diastolic volume (EDV) and end-systolic volume (ESV) in unsedated cattle. In the 16 healthy calves studied, it was possible, using a fast response thermodilution catheter, to obtain characteristic exponential steplike washout curves, allowing the calculation of right ventricular EF, EDV and ESV. Five to 10 successive thermodilution curves were recorded within a few minutes and two to five similar sets of measurements were performed throughout the same day to test the reproducibility of the technique. The same protocol was repeated the following day. Right ventricular EF, EDV and ESV were reproducible successively, throughout a given day and on following days. The mean intraset, intraday and interdays coefficients of variation ranged from a mean of 4.0 (SD 4.1) per cent to a mean of 18.2 (SD 7.9) per cent. Values of right ventricular volumes and EF agreed with those previously reported in various animal species. Thermodilution was, therefore, shown to be a useful method for measuring with a satisfactory reproducibility, right ventricular EF, EDV and ESV in the unsedated healthy calf [less ▲]

Hereditary muscular hypertrophy is a character that has been selected in several animal species for industrial meat production. The selection of this character in cattle produces animals of exceptional commercial value but ones with a lower aerobic capacity than that of conventional cattle. The purpose of this work was to study the role of cardiac function as a potential limiting factor of aerobic capacity in double-muscled calves. Two groups of healthy calves were studied, one consisting of nine calves of conventional conformation and the other of nine double-muscled calves. Pulmonary arterial and capillary wedge, central venous, and systemic arterial pressures were measured by fluid-filled catheters and recorded together with the electrocardiogram. Cardiac output was measured by the thermodilution technique. From these measurements, the heart rate, the cardiac and the stroke indices, the pulmonary and the systemic vascular resistances, and the cardiac power output were calculated. The parameters were recorded under basal resting conditions and during incremental dobutamine challenge, which allowed determination of the resting cardiac power output, the cardiac pumping capability, and the cardiac reserve. Dobutamine challenge induced a significant rise in cardiac and stroke indices, heart rate, and cardiac power output, a significant decrease in pulmonary and systemic vascular resistances, and no change in systemic and pulmonary arterial pressures. The cardiac reserve obtained in the present study was low in comparison with those previously reported in humans, dogs, and horses. This may be related to the poor running capability of bovine species relative to that of the former species.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

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.
