| Research Abstract |
In cattle, sleeping was increased and agonistic behavior was decreased in the order of whole day grazing, half day grazing, free stall rearing, and tethered rearing. Oxytocin was increased and N/L ratio and cortisol were decreased in grazing. Oxytocin was increased in eating of standing grasses than of harvested grasses. Stand-resting was decreased and sleep, feeding, lying, and affilative behaviors were increased in the enrichment rearing. Oxytocin was increased after being brushed. Behavior was diverse and oxytocin was increased after releasing to paddock.
