This change is partly justified on the assumption that captive-breeding (or hand-rearing) increases welfare of captive animals because these practices result in animals with reduced fear of humans.
Environmental enrichment is a common strategy used to improve the welfare of captive animals.
Few studies have been carried out on the welfare of captive bottlenose dolphins (Tursiops truncatus).
Environmental enrichment both improves the welfare of captive animals and increases the validity of research using these animals.
Enclosure complexity significantly influences activity budget and occurrence of stereotypic behaviours, highlighting the importance of appropriate enclosure design and enrichment for the welfare of captive bears.
However, so far no studies have investigated the impact of cage shape on the behaviour or welfare of captive flying birds.
Here, we demonstrate that a significant proportion of the variation in apparent welfare between captive carnivore species stems from specific aspects of natural behaviour.
Environmental enrichment strategies are used to improve both the physiological and psychological welfare of captive animals, which can be achieved by increasing the expression of natural behaviour and decreasing abnormal behaviours.
The aim of this study was to assess the welfare of captive bottlenose dolphins in open and closed facilities by measuring states of individual behavior and salivary cortisol concentrations.
And this issue, he adds, is far more complex than just comparing what's worth more: the welfare of captive animals or the survival of apes in the wild.
