Bayesian estimation of prevalence of paratuberculosis in dairy herds enrolled in a voluntary Johne’s Disease Control Programme in Ireland (2016)
Journal Article

Bovine paratuberculosis is a disease characterised by chronic granulomatous enteritis which manifests clinically as a protein-losing enteropathy causing diarrhoea, hypoproteinaemia, emaciation and, eventually death. Some evidence exists to suggest a... Read More about Bayesian estimation of prevalence of paratuberculosis in dairy herds enrolled in a voluntary Johne’s Disease Control Programme in Ireland.

Prediction of intramammary infection status across the dry period from lifetime cow records (2016)
Journal Article

The dry period is very important for mammary gland health, with the aim not only to cure existing intramammary infections (IMI) but also to prevent new IMI. Although it is known that the dry period is an important time for optimizing udder health, th...

Linking bone development on the caudal aspect of the distal phalanx with lameness during life (2016)
Journal Article

Claw horn disruption lesions (CHDL; sole hemorrhage, sole ulcer, and white line disease) cause a large proportion of lameness in dairy cattle, yet their etiopathogenesis remains poorly understood.

Use of early lactation milk recording data to predict the calving to conception interval in dairy herds (2016)
Journal Article

Economic success in dairy herds is heavily reliant on obtaining pregnancies at an early stage of lactation. Our objective in this study was to attempt to predict the likelihood of conception occurring by d 100 and 150 of lactation (days in milk, DIM)...

Challenges facing the farm animal veterinary profession in England: a qualitative study of veterinarians’ perceptions and responses (2016)
Journal Article

The farm animal veterinary profession in the UK has faced a number of challenges in recent decades related to the withdrawal of government funding and a contraction of the agricultural sector. They have come under pressure to respond by developing sk...

The effect of paratuberculosis on milk yield—a systematic review and meta-analysis (2015)
Journal Article

Bovine paratuberculosis is a disease characterized by chronic granulomatous enteritis causing protein-losing enteropathy. Adverse effects on animal productivity are key drivers in the attempt to control paratuberculosis at the farm level. Economic mo...

Test-retest reliability and predictive validity of a juvenile guide dog behavior test (2015)
Journal Article

The ability to measure stable and consistent behavioral traits in dogs would facilitate selection and assessment of working dogs, such as guide dogs. Ideally, these measures should predict suitability for the working role from a young age. This study...

Using the incidence and impact of health conditions in guide dogs to investigate healthy ageing in working dogs (2015)
Journal Article

This study aimed to use retirement data from working guide dogs to investigate healthy ageing in dogs and the demographic factors that influence ageing. Using a dataset of 7686 dogs spanning 20 years, dogs withdrawn for health reasons before they rea...

Molecular epidemiology of Streptococcus uberis clinical mastitis in dairy herds: strain heterogeneity and transmission (2015)
Journal Article

Multi Locus Sequence Typing was successfully completed on 494 isolates of S. uberis from clinical mastitis cases in a study of 52 commercial dairy herds over a 12 month period. In total, 195 sequence types (STs) were identified. S. uberis mastitis ca...

Evaluation of the usefulness at national level of the dairy cattle health and production recording systems in Great Britain (2015)
Journal Article

The aim of this study was to formally evaluate, qualitatively, the ability of existing recording systems to generate accurate and reliable estimates of the frequency of selected health conditions in the dairy herd of Great Britain. Fifty-nine recordi... Read More about Evaluation of the usefulness at national level of the dairy cattle health and production recording systems in Great Britain.

Recycling manure as cow bedding: potential benefits and risks for UK dairy farms (2015)
Journal Article

Material obtained from physical separation of slurry (recycled manure solids; RMS) has been used as bedding for dairy cows in dry climates in the US since the 1970s. Relatively recently, the technical ability to produce drier material has led to adop... Read More about Recycling manure as cow bedding: potential benefits and risks for UK dairy farms.

An investigation of the dynamics of intramammary infections acquired during the dry period on European dairy farms (2015)
Journal Article

The dry period is acknowledged as playing a key role in mastitis epidemiology and yet surprisingly few studies have explored dry period infection dynamics in detail.
