Achieving optimal welfare for the Nile hippopotamus (Hippopotamus amphibius) in North American zoos and aquariums.

abstract：:This experiment was carried out to investigate the long-term effects of enhancing cage complexity on behavioural measures of welfare in laboratory rats. We housed 72 rats in groups of four in either 'enriched' or 'unenriched' cages for six weeks. Scan and focal animal sampling were conducted in both the light and dark...
