Name: feed_vms Description: Feed pellets dispensed to cows at the Voluntary Milking System (VMS) during milking. There is no scale to weigh the actual amount of feed consumed. Each record is the total amount (kg) of feed pellets dispensed hourly - e.g., hour = 14:00:00 and feed_dispensed = 1.5, therefore this cow ate 1.5 kg of feed from 1 pm to 2 pm. If a cow started milking at 03:55:00 and finished at 04:05:00, there will be two records for that session, one for the amount dispensed until 4 am, and another for the amount dispensed until 5 am. Milking start and end times are not necessarily the same times for feeding, i.e., a cow could start milking at 03:55:00, but only start eating at 04:01:00, therefore she would only have one record for that session to reflect the amount she ate until 5 am.
