The Effect of Iron Dextran Injection on Daily Weight Gain and Haemoglobin Values in Whole Milk Fed Calves (2020)
Journal Article
Allan, J., Plate, P., & Van Winden, S. C. L. (2020). The Effect of Iron Dextran Injection on Daily Weight Gain and Haemoglobin Values in Whole Milk Fed Calves. Animals, 10(5), 853. https://doi.org/10.3390/ani10050853

Anaemia caused by iron deficiency has long been reported in dairy calves. This study investigated iron deficiency anaemia on UK dairy farms feeding whole milk and evaluated the effect of iron supplementation on the daily weight gain (DG) and haemoglo...

Minimally Invasive Markers of Stress and Production Parameters in Dairy Cows before and after the Installation of a Voluntary Milking System (2020)
Journal Article
Jerram, L. J., Van Winden, S. C. L., & Fowkes, R. C. (2020). Minimally Invasive Markers of Stress and Production Parameters in Dairy Cows before and after the Installation of a Voluntary Milking System. Animals, 10(4), 589. https://doi.org/10.3390/ani10040589

Automatic milking systems (AMS) are a low-labour alternative to conventional parlours, with previous studies demonstrating that cows vary in their ability to cope with the change to AMS. Cortisol expression can be combined with other measures to asse...

Infectious bovine keratoconjunctivitis (IBK) caused by Moraxella bovis is commonly seen in the summer months spread by face flies. This trial investigated the difference in incidence of IBK cases from natural exposure between two groups of animals, o...

Risk of Lameness in Dairy Cows with Paratuberculosis Infection (2019)
Journal Article
Smith, J., & Van Winden, S. C. L. (2019). Risk of Lameness in Dairy Cows with Paratuberculosis Infection. Animals, 9(6), 339. https://doi.org/10.3390/ani9060339

Johne’s disease (JD) is an important disease affecting the UK dairy industry, as is cattle lameness. An association between JD and lameness has been suggested; however, little evidence exists to support this. The purpose of this study was to determin...

Mycobacterium avium paratuberculosis infection of calves – The impact of dam infection status (2019)
Journal Article
Patterson, S., Bond, K., Green, M., Van Winden, S. C. L., & Guitian, J. (2019). Mycobacterium avium paratuberculosis infection of calves – The impact of dam infection status. Preventive Veterinary Medicine, https://doi.org/10.1016/j.prevetmed.2019.02.009

Johne’s disease, caused by Mycobacterium avium subsp. paratuberculosis (MAP), is a chronic condition of dairy cattle, and is endemic in the UK. Lack of understanding of the relative importance of different transmission routes reduces the impact of co...

Development of clinical sign-based scoring system for assessment of omphalitis in neonatal calves (2018)
Journal Article
Steerforth, D., & Van Winden, S. C. L. (2018). Development of clinical sign-based scoring system for assessment of omphalitis in neonatal calves. Veterinary Record, https://doi.org/10.1136/vr.104213

Omphalitis contributes significantly to morbidity and mortality in neonatal calves. Diagnosis of omphalitis is based on the local signs of inflammation—pain, swelling, local heat and purulent discharge. An abattoir trial identified an optimal, sign-b...
