Table 1.
Behaviors recorded from video using behavior sampling and continuous recording during the 30-min novel TMR test.
Fig 1.
Latency to start eating novel TMR once oriented to, or in proximity of, the TMR bucket.
Dairy calves with no prior hay experience (Control, n = 9), prior experience consuming hay from a pipe feeder (Pipe, n = 8), and prior experience consuming hay from a bucket (Bucket, n = 8) were evaluated for their response to the introduction of novel TMR at 50 d of age. Boxplots represent the median (black line within box) and first and third quartiles (25 and 75% of data). Whiskers extend to the lowest and highest values that are not outliers (values that are 1.5x the interquartile range); outliers (o) and means (x) are also presented.
Fig 2.
Proportion of time spent eating TMR (a) and total TMR intake (b) during a 30-min novel feed test. Dairy calves with no prior hay experience (Control), prior experience consuming hay from a pipe feeder (Pipe), or prior experience consuming hay from a bucket (Bucket) were evaluated for their response to the introduction of novel TMR at 50 d of age. Boxplots represent the median (black line within box) and first and third quartiles (25 and 75% of data). Whiskers extend to the lowest and highest values that are not outliers (values that are 1.5x the interquartile range); outliers (o) and means (x) are also presented.
Fig 3.
Proportion of calves eating TMR or lying down over the first 30 min following introduction of TMR.
Dairy calves with no prior hay experience (Control), prior experience consuming hay from a pipe feeder (Pipe), or prior experience consuming hay from a bucket (Bucket) were evaluated for their response to the introduction of novel TMR at 50 d of age. Behavior was scored continuously and binned by minute. Bright yellow indicates that all calves in that treatment performed the behavior at that minute, while dark blue indicates no individuals performed the behavior.
