摘要:

Idiopathic laryngeal paralysis in dogs is now a frequently recognised disorder, particularly in certain breeds such as the Labrador retriever, Afghan hound and Irish setter. Since it occurs in the older animal, distinguishing the clinical signs and their significance from lower respiratory tract or cardiac disease can be challenging. At present little is known about its aetiology and therefore the treatment is directed at relieving the clinical signs.

摘要:

All cases of lameness that occurred in cows from three dairy herds between August 1989 and July 1990 were examined every 2 weeks from the onset of lameness until the lesions resolved. The incidences of herd lameness were 38%, 22% and 2%. Some 186 clinical lesions were identified in 134 cases of lameness in 120 cows. Sole bruising (42%) and white line separation (39%) were the most frequently diagnosed conditions. Lateral digits of the hind limbs were the most affected. The mean time from the onset of lameness to clinical recovery was 27 days and to lesion recovery was 35 days. The peak incidence of lameness occurred during winter for autumn-calving cows and during the late spring for spring-calving cows. The onset of lameness was associated with the stage of lactation and wet weather conditions. Survival analysis revealed that the probability of an individual cow lasting in the milking herd for any specified period of time without becoming lame was highly associated with both her herd environment and her age. Total lactation yields of milk, milk fat and milk protein were lower for cows suffering from lameness than for herd-mates matched on age and proximity of calving date (p<0.05). Reproductive performance was also poorer in lame cows than in their herd-mates.

摘要:

A 3-week-old Thoroughbred colt was presented for weakness and cyanosis. A pansystolic regurgitant murmur and other physical findings suggested that the foal developed pulmonary oedema as a consequence of congenital heart disease. A large atria1 septal defect, a high ventricular septal defect and dysplasia of the atrioventricular valves were visualised echocardiographically. A persistent common atrioventricular canal was observed at necropsy.

摘要:

A complicated, segmented fracture of the femoral diaphysis in a dog is presented. Complications arose from multiple surgeries and subsequent osteomyelitis. Repair was staged by firstly removing all implants, secondly treating the osteomyelitis with appropriate antibiotics while spanning the cortical-deficient fracture site with a Kirschner external fixator, and finally rigid fixation of the fracture with incorporation of an ethylene oxide-sterilised intercalary cortical allo-implant. Principles of bone grafting are reviewed.

摘要:

A vertebral body abscess extending into the epidural space causing spinal cord compression was diagnosed in the cervical spinal cord in four lambs and the thoracic spinal cord in four lambs. The affected lambs were aged between 4 and 10 weeks and clinical signs had been present for 7–21 days before veterinary examination. Treatment with high doses of penicillin did not result in an improvement of the neurological signs and all lambs were destroyed on humane grounds.

摘要:

A field trial was set up to determine the effects of mechanical shortening of long incisors (bite correction) of ewes with early periodontal disease on the progress of the disease and on their body weights.
