Using hormones to manage dairy cow fertility: the clinical and ethical beliefs of veterinary practitioners (2013)
Journal Article

In the face of a steady decline in dairy cow fertility over several decades, using hormones to assist reproduction has become common. In the European Union, hormones are prescription-only medicines, giving veterinary practitioners a central role in t...

Prevalence and effect of uterine luminal free fluid on pregnancy and litter size in bitches (2013)
Journal Article

Association between somatic cell count early in the first lactation and the lifetime milk yield of cows in Irish dairy herds (2013)
Journal Article

Change in lifetime milk yield is an important component of the cost of diseases in dairy cows. Knowledge of the likelihood and scale of potential savings through disease prevention measures is important to evaluate how much expenditure on control mea...

Temporal associations between low body condition, lameness and milk yield in a UK dairy herd (2013)
Journal Article

Previous work has hypothesised that cows in low body condition become lame. We tested this in a prospective longitudinal study. Body condition score (BCS), causes of lameness and milk yield were collected from a 600-cow herd over 44-months. Mixed eff...

Association of season and herd size with somatic cell count for cows in Irish,English, and Welsh dairy herds (2013)
Journal Article

The aims of this study were to describe associations of time of year, and herd size with cow somatic cell count (SCC) for Irish, English, and Welsh dairy herds. Random samples of 497 and 493 Irish herds, and two samples of 200 English and Welsh (UK)...

A Bayesian elicitation of veterinary beliefs regarding systemic dry cow therapy: variation and importance for clinical trial design (2012)
Journal Article

The two key aims of this research were: (i) to conduct a probabilistic elicitation to quantify the variation in veterinarians’ beliefs regarding the efficacy of systemic antibiotics when used as an adjunct to intra-mammary dry cow therapy and (ii) to...

A semi-parametric model for lactation curves: development and application (2012)
Journal Article

We propose a semi-parametric model for lactation curves that, along with stage of lactation, accounts for day of the year at milk recording and stage of gestation. Lactation is described as having 3 different phases defined by 2 change points of whic... Read More about A semi-parametric model for lactation curves: development and application.

Associations between udder health and reproductive performance in United Kingdom dairy cows (2012)
Journal Article

The objective of this research was to evaluate the relationship between udder health and reproductive performance in UK dairy cows. Data from 80 herds were restructured such that each unit of data represented a 2-d period during lactation where a cow...

A comparison of broad-spectrum and narrow-spectrum dry cow therapy used alone and in combination with a teat sealant (2011)
Journal Article

The dry period is a critical time in the lactation cycle, offering the optimum time for cure of existing intramammary infection (IMI), while also encompassing the periods of highest susceptibility to new intramammary infection. Until recent years, in... Read More about A comparison of broad-spectrum and narrow-spectrum dry cow therapy used alone and in combination with a teat sealant.

Association between somatic cell count and serial locomotion score assessments in UK dairy cows (2011)
Journal Article

This research investigated the effect of lameness, measured by locomotion score (LS) on the somatic cell count (SCC) of UK dairy cows. The data set consisted of 11,141 records of SCC and LS collected monthly on 12 occasions from 1,397 cows kept on 7...
