Predictive modelling of deviation from expected milk yield in transition cows on automatic milking systems (2024)
Journal Article

The transition period is a pivotal time in the production cycle of the dairy cow. It is estimated that between 30% and 50% of all cows experience metabolic or infectious disease during this time. One of the most common and economically consequential... Read More about Predictive modelling of deviation from expected milk yield in transition cows on automatic milking systems.

Hoof lesions in partly housed pasture-based dairy cows (2022)
Journal Article

Lameness is a symptom of a painful disorder affecting the limbs, which impacts dairy cow welfare and productivity. Lameness is primarily caused by hoof lesions. The prevalence of different lesion types can differ depending on environmental conditions... Read More about Hoof lesions in partly housed pasture-based dairy cows.

Antimicrobial resistance in dairy slurry tanks: a critical point for measurement and control (2022)
Journal Article

Waste from dairy production is one of the largest sources of contamination from antimicrobial resistant bacteria (ARB) and genes (ARGs) in many parts of the world. However, studies to date do not provide necessary evidence to inform antimicrobial res...

Lameness prevalence and management practices on Irish pasture-based dairy farms (2022)
Journal Article

Background: Lameness is a painful disease, which negatively impacts dairy cow production and welfare. The aim of this observational study was to determine herd lameness prevalence, describe current lameness management practices and identify the prese...

Use of Non-Steroidal Anti-Inflammatory Drugs and Attitudes to Pain in Pasture-Based Dairy Cows: A Comparative Study of Farmers and Veterinarians (2022)
Journal Article

Pain is a significant welfare concern within the dairy industry. Recognizing and managing pain are important factors for safeguarding animal welfare. A questionnaire was sent via post to Irish dairy farmers and large animal veterinarians to assess at...

A randomised controlled trial to evaluate the impact of indoor living space on dairy cow production, reproduction and behaviour (2022)
Journal Article

As a global society, we have a duty to provide suitable care and conditions for farmed livestock to protect animal welfare and ensure the sustainability of our food supply. The suitability and biological impacts of housing conditions for intensively...

The effect of environmental temperature on average daily gain in preweaned calves: A randomized controlled trial and Bayesian analysis (2022)
Journal Article

Neonatal calves are relatively susceptible to heat loss, and previous research suggests that reduced environmental temperatures are associated with reduced average daily gain (ADG) during the preweaning phase. Current methods of mitigating negative e... Read More about The effect of environmental temperature on average daily gain in preweaned calves: A randomized controlled trial and Bayesian analysis.

Preventive hoof trimming in dairy cattle: Determining current practices and identifying future research areas (2022)
Journal Article

Background: The extent to which preventive hoof trimming is implemented on Great Britain's (GB) dairy farms is unknown. The aims of this study were to determine common practices and capture producers’ input on key areas that require further research....

Cow- and herd-level risk factors for lameness in partly housed pasture-based dairy cows (2021)
Journal Article

Lameness in dairy cows is a major animal welfare concern and has substantial economic impact through reduced production and fertility. Previous risk factor analyses have focused on housed systems, rather than those where cows were grazed for the majo...

Improving growth rates in preweaning calves on dairy farms: A randomized controlled trial (2021)
Journal Article

Previous research has identified key factors associated with improved average daily gain (ADG) in preweaning dairy calves and these factors have been combined to create a web app–based calf health plan (www.nottingham.ac.uk/herdhealthtoolkit). A rand... Read More about Improving growth rates in preweaning calves on dairy farms: A randomized controlled trial.

Practical data skills for the farm animal vet (2021)
Journal Article

Background: While farm animal veterinarians receive extensive training in the diagnosis and treatment of individual animals, population medicine or ‘herd health’ has also become commonplace in modern production animal veterinary medicine. Clinicians... Read More about Practical data skills for the farm animal vet.

From the other perspective: Behavioural factors associated with UK sheep farmers’ attitudes towards antibiotic use and antibiotic resistance (2021)
