Infectious bronchitis is caused by a coronavirus, infectious bronchitis virus (IBV). Infectious bronchitis is an acute and highly contagious disease of economic importance due to the reduction in weight gain observed with infected broilers and the drop in egg quality and production associated with infected laying hens. The presence of deep pectoral myopathy has been associated with IBV variants...

In this study, we compare the level and distribution of genetic variation between South African conserved and village chicken populations using microsatellite markers. In addition, diversity in South African chickens was compared to that of a reference data set consisting of other African and purebred commercial lines. Three chicken populations Venda, Ovambo and Eastern Cape and four conserved ...

The presence of rotavirus infection in broiler chickens (1-2 weeks old) was studied. A total of 232 faecal specimens were collected during the period from July to September 2004 and examined by polyacrylamide gel electrophoresis and silver staining (PAGE-ss) technique for the presence of rotavirus dsRNA in the Department of Medicine, Faculty of Veterinary Science, Bangladesh Agricultural Univer...

We describe Salmonella control programs of broiler chickens, layer hens, and pigs in Denmark. Major reductions in the incidence of foodborne human salmonellosis have occurred by integrated control of farms and food processing plants. Disease control has been achieved by monitoring the herds and flocks, eliminating infected animals, and diversifying animals (animals and products are processed di...

the purpose of this study was to determine the incidence of rickets types in broiler chickens on the basis of gross and microscopic lesions in field clinical cases with regard to differential pathomorphological diagnosis.clinical, serological, gross anatomy and histological investigations were carried out in broiler chickens with signs of rickets. the survey included 12 finisher broiler flocks ...
