Enrichment devices for green turtles (Chelonia mydas) reared in captivity programs
Environmental enrichment supports the well-being and welfare of captive animals. In the current study, the most suitable form of enrichment device for captive green turtles (Chelonia mydas) was investigated, to support head-start programs rearing turtles for release into their natural habitat. Fifteen-day-old turtles (113–114 g initial weight, n = 75) were randomly distributed into 15 experimental plastic tanks, […]
An enrichment object that reduces aggressiveness and mortality in caged laying hens
The effect on aggressive pecking activity and mortality by an environmental enrichment device was examined. In this study, 2955 White Leghorn chickens from three different lines were used in six separate experiments. Experiments were conducted with chickens during their first or second laying period.
