Spatial variability in shrub vegetation across dune forms in central Saudi Arabia (2018)
Journal Article
Bradley, A. V., Haughan, A. E., Al-Dughairi, A., & McLaren, S. J. (2019). Spatial variability in shrub vegetation across dune forms in central Saudi Arabia. Journal of Arid Environments, 161, 72-84. doi:10.1016/j.jaridenv.2018.10.003

In desert dune environments, vegetation may be an indicator of dune stability and rates of sediment transport. As topography and underlying controls of vegetation vary over large spatial areas variations in dune form make scaling up of field research... Read More

A multi-scale approach interpreting sediment processes and distribution from desert sand colour in central Saudi Arabia (2018)
Journal Article
Bradley, A. V., McLaren, S. J., Al-Dughairi, A., & Khalaf, N. R. (2018). A multi-scale approach interpreting sediment processes and distribution from desert sand colour in central Saudi Arabia. Earth Surface Processes and Landforms, 43(14), 2847-2862. doi:10.1002/esp.4438

In central Saudi Arabia the redness of sands observed on satellite imagery, often related to iron oxide amount, was used to better interpret geomorphic processes operating in the area. To compare variations between dune and interdune morphology, line... Read More

Quantitative analysis of antimicrobial use on British dairy farms (2017)
Journal Article
Hyde, R. M., Remnant, J. G., Bradley, A. J., Breen, J. E., Hudson, C. D., Davies, P. L., …Green, M. J. (in press). Quantitative analysis of antimicrobial use on British dairy farms. Veterinary Record, 181(25), doi:10.1136/vr.104614. ISSN 0042-4900

Antimicrobial resistance has been reported to represent a growing threat to both human and animal health, and concerns have been raised around levels of antimicrobial usage (AMU) within the livestock industry. To provide a benchmark for dairy cattle... Read More

Factors affecting the cost-effectiveness of on-farm culture prior to the treatment of clinical mastitis in dairy cows (2017)
Journal Article
Down, P., Bradley, A. J., Breen, J., & Green, M. J. (2017). Factors affecting the cost-effectiveness of on-farm culture prior to the treatment of clinical mastitis in dairy cows. Preventive Veterinary Medicine, 145, doi:10.1016/j.prevetmed.2017.07.006. ISSN 0167-5877

The objective of this study was to use probabilistic sensitivity analysis to evaluate the cost-effectiveness of using an on-farm culture (OFC) approach to the treatment of clinical mastitis in dairy cows and compare this to a ‘standard’ treatment app... Read More

SimiVal, a multi-criteria map comparison tool for land-change model projections (2016)
Journal Article
Bradley, A. V., Rosa, I. M., Pontius, R. G., Ahmed, S. E., Araújo, M. B., Brown, D. G., …Ewers, R. M. (2016). SimiVal, a multi-criteria map comparison tool for land-change model projections. Environmental Modelling and Software, 82, 229-240. doi:10.1016/j.envsoft.2016.04.016

The multiple uses of land-cover models have led to validation with choice metrics or an ad hoc choice of the validation metrics available. To address this, we have identified the major dimensions of land-cover maps that ought to be evaluated and devi... Read More

Prediction of intramammary infection status across the dry period from lifetime cow records (2016)
Journal Article
Henderson, A., Hudson, C., Bradley, A. J., Sherwin, V., & Green, M. J. (2016). Prediction of intramammary infection status across the dry period from lifetime cow records. Journal of Dairy Science, 99(7), doi:10.3168/jds.2015-10684. ISSN 0022-0302

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... Read More

Journal Article
Down, P., Bradley, A. J., Breen, J., Hudson, C., & Green, M. J. (2016). Current management practices and interventions prioritised as part of a nationwide mastitis control plan. Veterinary Record, 178(449), doi:10.1136/vr.103203. ISSN 0042-4900

The objectives of this study were to report performance and management data taken from a sample of UK dairy farms that have participated in the Agriculture and Horticulture Development Board Dairy Mastitis Control Plan (DMCP) and to identify importan... Read More

Molecular epidemiology of Streptococcus uberis clinical mastitis in dairy herds: strain heterogeneity and transmission (2015)
Journal Article
Davies, P., Archer, S. C., Emes, R. D., Bradley, A. J., Leigh, J., & Green, M. J. (2016). Molecular epidemiology of Streptococcus uberis clinical mastitis in dairy herds: strain heterogeneity and transmission. Journal of Clinical Microbiology, 54(1), doi:10.1128/JCM.01583-15. ISSN 0095-1137

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... Read More

Recycling manure as cow bedding: potential benefits and risks for UK dairy farms (2015)
Journal Article
Lech, K. A., Archer, S. C., Breen, J. E., Green, M. J., Ohnstad, I. C., Tuer, S., & Bradley, A. J. (in press). Recycling manure as cow bedding: potential benefits and risks for UK dairy farms. Veterinary Journal, 206(2), doi:10.1016/j.tvjl.2015.08.013. ISSN 1532-2971

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
