Herd-level economic losses associated with Johne's disease on US dairy operations.

TL;DR: Risk factors associated with Johne's disease in this study confirmed those management practices generally recommended for disease control, including management practices similar to those used by managers unfamiliar with the disease.
Journal ArticleDOI
The Epidemiology of Bacterial Diseases in Food-Size Channel Catfish
TL;DR: Three possible risk factors associated with ESC/columnaris are identified, namely, operation size, stocking density, and feeding rate, which generate hypotheses about managerial and environmental interactions that represent substantial risks to production.
Journal ArticleDOI
Papillomatous digital dermatitis and associated risk factors in US dairy herds.
TL;DR: It is suggested that a high percentage of herds with digital dermatitis could be prevented and management strategies to potentially prevent or reduce incidence ofdigital dermatitis on dairy operations include those related to biosecurity and 'cow hoof' environmental conditions.
Journal Article
Risk factors for initial respiratory disease in United States' feedlots based on producer-collected daily morbidity counts.
TL;DR: Mixed gender groups, cattle from multiple sources and increasing distance shipped were associated with increased risk for initial respiratory morbidity, and heavier entry weight was associated with decreased morbidity risk.
