Risk assessments are important tools to identify deficits in biosecurity management practices. A major strength of some existing tools is that they facilitate cross-country comparisons. However, a weakness is their failure to account for unique intra-national farming enterprise structures such as, for example, pasture-based dairying. Currently, the...
Bovine respiratory disease (BRD) is a leading cause of mortality and compromised welfare in bovines. It is a polymicrobial syndrome resulting from a complex interplay of viral and bacterial pathogens with environmental factors. Despite the availability of vaccines, incidence and severity in young calves remains unabated. A more precise analysis of...
Bovine respiratory disease (BRD) presents a challenge to farmers all over the globe not only because it can have significant impacts on welfare and productivity, but also because diagnosis can prove challenging. Several clinical scoring systems have been developed to aid farmers in making consistent early diagnosis, 2 examples being the Wisconsin (...
Background
Summer scour syndrome (SSS) is a recently identified pathological condition affecting weaned dairy and dairy-beef calves during their first grazing season in Ireland. The syndrome is characterised by diarrhoea, weight loss, weakness, and can ultimately lead to death in some calves. Oral and oesophageal ulcerations are present in some cas...
Bovine respiratory disease (BRD) is a challenge in all housed farming systems that raise calves. Farm to farm variation in BRD prevalence can be partially attributed to variation in host immunity, pathogens and housing environment. Unlike host immunity and BRD pathogens, housing environment has not been well investigated. The objective of this syst...
Bovine respiratory disease (BRD) is one of the leading causes of mortality and morbidity in calves across diverse management systems. Despite expert opinion often citing the influence of housing environment on the level of respiratory disease in calf groups, there have been few reviews of environmental factors that predispose to BRD. This systemati...
Introduction
Bovine respiratory disease (BRD) has a significant impact on the health and welfare of dairy calves. It can result in increased antimicrobial usage, decreased growth rate and reduced future productivity. There is no gold standard antemortem diagnostic test for BRD in calves and no estimates of the prevalence of respiratory disease in s...

BRD is one of the leading causes of mortality/morbidity in calves across diverse management systems. Despite the fact that expert opinion often cites the influence that housing environment can have on the level of respiratory disease in a group of calves there have been few reviews of the environmental factors predisposing to BRD. The objective of...
Abstract Background Retention of veterinary practitioners has arisen as a significant problem in recent years in Ireland. No prior Irish peer-reviewed publications have addressed this problem. An online questionnaire was available through social media and via email to Irish vets from January to November 2019. The aim of this survey was to ascertain...
The objective of this study was to investigate the quality of colostrum produced by Irish dairy cows on commercial farms and the factors that influence it. A convenience sample of 16 dairy herds was used, from which 212 samples were collected. An average of 13 samples were collected per farm. Farmers were asked to collect samples of the colostrum t...
BOVINE neonates are born virtually agammaglobulinaemic (Klaus and others 1969) and successful passive transfer of maternal immunoglobulin depends on efficient absorption of an adequate volume of colostrum of sufficient quality. However, colostrum may also represent a potential source of pathogens such as Mycobacterium avium subspecies paratuberculo...
