Figure 2.

Percentage of observations spent standing, lying, and feeding, in the morning (0800 to 1100 h) and afternoon (1200 to 1500 h) by heifers 17.8 ± 1.0 (mean ± SD) wk of age housed in groups (10 ± 2 heifers/group) on pasture. Heifers were previously reared individually (IH; n = 17) or in pairs (PH; n = 20) until 8.8 ± 0.4 (mean ± SD) wk of age. *P < 0.05. The box extends from the 25th to the 75th percentile with a line at the median. Whiskers extend from the box a distance of 1.5 times the interquartile range with values outside this range shown as circles.
