An example dataset containing feeding behavior and visit records for cattle over a two-day period (2020-10-31 to 2020-11-01). Each day's data is stored as a separate data frame within a list. This is the cleaned data output from the vignettes (i.e., "Articles" listed on the package website) "Data cleaning" code.
Format
A list of 2 data frames, one for each date (2020-10-31, 2020-11-01), with each data frame containing the following 10 variables:
- transponder
integer, unique electronic ID for each bin
- cow
integer, animal ID number
- bin
integer, feeding bin location number
- start
POSIXct, timestamp when feeding event started
- end
POSIXct, timestamp when feeding event ended
- duration
integer, duration of feeding event in seconds
- start_weight
numeric, weight of feed (kg) at start of feeding event
- end_weight
numeric, weight of feed (kg) at end of feeding event
- intake
numeric, amount of feed consumed (kg) during the event (calculated as start_weight - end_weight)
- date
Date, calendar date of the feeding event
Source
Collected using an Insentec automatic feeder at University of British Columbia Dairy Education and Research Centre from October 31 to November 1, 2020.
Details
The dataset contains detailed feeding behavior for multiple cattle over two consecutive days. Each entry represents a distinct feeding event where an animal visited a feed bin.
Examples
# Access data for the first day
first_day <- all_fed[["2020-10-31"]]
# Calculate average intake per feeding event
mean(first_day$intake)
#> [1] 0.7443296
# Count feeding events by cow on November 1
