    Contributor(s):: Chaya, L., Cowan, E., McGuire, B.

    We examined if time spent in turnout influenced behaviour during turnout for horses maintained in stalls and given either 2 h/week (n=7) or 12 h/week (n=7) of turnout. Horses turned out for 2 h/week were more likely than those turned out for 12 h/week to trot, canter, and buck. Frequency of...

    The behavioural time budget of 140 turkey poults housed on litter in groups of 10-11 in small pens was recorded by individual scan sampling from 1-day-old to 12-weeks-old. Over this period some behaviour (sitting/sleeping) remained relatively constant, some (feeding) declined and remained low,...
