- Statement
- The initial study was undertaken with Welsh Mountain ewes (n=5) housed in urine collection apparatus, equipped with tri-axial accelerometers glued to their hind. The time of ewes exhibiting the urination squatting posture was recorded and the volume of each individual urine event was also recorded. The data form this trial were analysed blind with the Boolean algorithm and we recorded no records of false positive or negatives in the dataset, suggesting the technique would work well for the field deployments. We regressed the data for squat time with urine volume, and obtained a linear relationship. This linear relationship was subsequently used to estimate urine volume from squat time only in the field campaigns. For the field campaigns Welsh Mountain ewes (n=30) were equipped with accelerometers glued to their hinds and deployed to a semi-improved upland 11.5 ha field (240-340 m asl) at the Henfaes Research Centre (53°13′N, 4°0ʹW) in spring (12th May 2016 to 16th June 2016) and autumn (28th September 2016 to 3rd November 2016). The following year a different set of sheep (n=30) from the same flock were deployed to an area of common grazing land (495 ha) on the Carneddau mountain range (322 - 943 m asl) within the Snowdonia National Park (53°22′N, 3°95′W), Wales, UK. Sheep were deployed in spring (31st May 2017 to 5th July 2017) and autumn (18th September 2017 to 28th October 2017) at the second study site. This resulted in a large dataset for the time, squatting duration, frequency and estimated volume of individual sheep urine events while free-grazing. Data for rainfall and temperature across the four study periods are also provided.
