Summary

The effects of two levels of roughage (18 or 40%), of DES implantation (36 mg, twice), and of the addition of adjoining dirt yards to pens with concrete slatted floors, on the behaviour of intact male calves, were examined in a 2 x 2 x 2 factorial experiment. Observations were carried out on four days, every 15 min for 24 hr. Activities recorded were: standing, lying, eating, drinking, ruminating, jumping and idling.

Animals on the high roughage diet spent 26% more time eating, 5% more time drinking, and 19% more time ruminating, than those on the low roughage diet.

Most of the rumination was performed while the animals were lying down. Animals allowed yards adjoining their pens spent 20% less time ruminating and 13% more time jumping than animals confined to pens alone. Those allowed the yard preferred to stand there and to lie down in the pen. The yards were used more on a cool day than on a hot day.
