Visits of housed cattle to GreenFeed units (2016-2023)

This dataset comprises data on visits to a GreenFeed unit by housed beef cattle, including dates and times, animal identification and visit number. The GreenFeed system (C-lock Inc., Rapid City, SD, USA) is designed to measure greenhouse gases (carbon dioxide and methane) emissions by animals visiting the unit. To encourage the visit, the GreenFeed dispenses pelleted feed to a visiting animal. The animal is identified by their radio frequency identification ear tag, and this is related back to their UK Offical Tag number. Greenhouse gas emissions from the cattle can be found elsewhere (http://resources.rothamsted.ac.uk/farmplatform) but where there are multiple visits by an animal on the same day, the emissions are averaged. This dataset does not contain any greenhouse gas emissions, but does present the date and time of each visit to the GreenFeed system. It is anticipated that this data could be used to study cattle behaviour and hierarchies.
