摘要:

In order to provide further evidence for the association of an indurative lymphocytic mastitis in sheep with MVV (maedi‐visna virus) infection, an experimental study was performed. Fourteen MVV‐free pregnant ewes, 2 years of age, were divided into two groups. Eight were intravenously inoculated with MVV (strain ZZV‐1050); six ewes served as sham‐inoculated controls. Post‐mortem exat. inations were carried out at 8, 16 and 28 months.

摘要:

At slaughter the lungs of 2138 veal calves (13 transport groups, mainly from different farms) were examined. Lung and pleural lesions were classified by degree of extension and pathomorphological features, and the accompanying carcass weights were measured. Seventeen percent of the calves had extensive lung lesions, extensive pleural lesions or both, and their mean carcass weight was reduced by 4.3 kg (p<0.05). The percentage of calves with extensive lesions varied between transport groups from 4% to 33%. All pleural lesions were adhesive. Most lung lesions (93%) were classified as cuffing/exudative pneumonia. Slaughterhouse inspection of lungs can be used as a non‐clinical parameter of respiratory disease in veal calves.

摘要:

A single oral dosage of furaltadone and nitrofurazone (14.0 mg/kg) to 5 preruminant calves (in a cross‐over trial) revealed mean maximum plasma concentration of 2.5 and 3.5 pg/ml, respectively, at approximately 3 h after administration. The final elimination half‐lives of furaltadone and nitrofurazone were 2.5 and 5 h, respectively.

摘要:

Five live virus vaccines against avian infectious laryngotracheitis were studied with regard to safety, immunogenicity and route of administration. Significant differences in virulence between the vaccine strains were found. Reduced virulence was accompanied by a reduction of immunogenicity and capacity to spread.

摘要:

The treatment of 133 dogs with behavioural problems is reviewed. The problems most frequently presented concerned aggressive behaviour and/or fear (agonistic behaviour). The combination of problems of dominance and problem behaviour stimulating conditioning (PBSC) was a diagnosis made significantly more often than others. The owner's inability to control the dog appeared to be associated primarily with aggression, but also with fear, in the dog.

摘要:

The kinetics of unconjugated3H‐bilirubin are described in 25 healthy dogs and 35 dogs with spontaneous hepatobiliary or haemolytic disease, using a two‐compartment model. The bilirubin production rates from erythrocyte degradation (PE), ineffective erythropoiesis (PI) and catabolism of hepatic haemoproteins (PI), were derived from the incorporation of14C‐glycine into haemoglobin and stercobilin. These combined measurements permitted an integral survey of bilirubin metabolism in health and disease. The concentration of unconjugated bilirubin in plasma and its of total bilirubin levels were similar in hepatic and haemolytic disorders.

摘要:

With a99mTc‐labelled aerosol an inhalation (ventilation) image of the lungs was obtained. A lung perfusion image was obtained with99mTc‐labelled macro‐aggregates. The data from the gamma camera were stored in a computer and the inhalation‐perfusion (I/P) ratio was calculated for the total lung as well as for one half another selected region, and a local (pixel) area. In the anaesthetised dog in sternal recumbency, the I/P ratio decreased from the cranial to the caudal lung regions. Hence in the dog gravity is not the only determinant of the I/P ratio distribution, as it is assumed to be in man. Position and anaesthesia appeared to influence the distribution of I/P ratios within the lung.

摘要:

In 54 of 99 dogs with atrial fibrillation heart function was examined scintigraphically. Data on the ejection fraction (EF), end‐diastolic volume (EDV) and regurgitation fraction (RF) are presented. Of these animals 37 had a seriously decreased EF (< 30%) with a more or less normal RF value, whereas a smaller group (17) had a moderately decreased EF (but ≥ 30%) and a seriously increased RF value. In both groups the EDV was increased.

摘要:

General aspects of avian clinical pathology are reviewed. It is concluded that in a clinical setting a volume of blood equivalent to 1 per cent of body weight can be collected safely from avian species for laboratory examinations. The anticoagulant of choice for most laboratory investigations is lithium heparin. In most bird species the right jugular vein is the preferred site for routine blood sampling. The use of a vacuum system greatly facilitates the procedure. The importance of immediately processing blood samples is explained. The many variables that may influence haematological or biochemical parameters are discussed and the reasons for determining blood chemical reference values by non‐parametric methods are emphasised.

摘要:

A review is presented of current knowledge with regard to blood chemistry for the diagnosis of hepatobiliary disease in birds. Straightforward conclusions are difficult, because research on this subject has been limited.
