Abstract Extract Dental abnormalities of sheep are common and in many parts of the world are the main reason for culling otherwise-healthy breeding ewes before the end of their natural reproductive life, leading to increased flock replacement costs. Excessive incisor-tooth wear and periodontal disease are considered the two most important syndromes ...

The pathology of Johne's disease in sheep
Australian Veterinary Journal, 1990SUMMARY The clinical, gross and histopathological findings in 50 sheep affected with Johne's disease are described. Clinically 90% were emaciated and 20% showed severe diarrhoea. On necropsy there was thickening of the walls of the intestines, particularly of the ileum, caecum and less frequently the jejunum, but in 36% of sheep the changes were only ...

Genetic Diseases of Sheep and Goats
Veterinary Clinics of North America: Food Animal Practice, 1990Congenital malformations and inherited disorders constitute a substantial proportion of the afflictions seen in sheep and goats. Of these, malformations tend to be similar in both species, whereas the genetic diseases encountered to date, with the exception of a few, are different. Of the 28 genetic diseases of sheep and goats described in this review,

SUMMARY Outbreaks of ovine white liver disease (WLD) on 7 farms in eastern Victoria were investigated. Most occurred in late spring and mainly affected lambs 3 to 6 months old, with a morbidity of 20 to 100% and mortality of 8 to 15%. Clinically affected lambs showed illthrift, emaciation and bilateral, serous, ocular discharge.

Nairobi sheep disease is probably the most pathogenic virus known for sheep and goats. It is transmitted by an Ixodid tick, both trans-stadially and transovarially and causes an acute gastroenteritis. In totally susceptible populations, mortality rates of over 90% regularly occur. The infection also causes abortion.

Emerging parasitic diseases of sheep
Veterinary Parasitology, 2012There have been changes in the emergence and inability to control of a number of sheep parasitic infections over the last decade. This review focuses on the more globally important sheep parasites, whose reported changes in epidemiology, occurrence or failure to control are becoming increasingly evident.
