Assessment of environmental enrichment for different primate species under low budget: A case study

The 2011 European Union Zoo Inquiry presented evidence that most zoos fail to achieve adequate levels of nonhuman animal welfare. Appropriate environmental enrichment (EE) can play a role in the promotion of welfare. However, financial and staff constraints frequently make...

Claw condition and claw health in dairy cows: how important is access to pasture?

Housing cows on hard flooring is associated with increased claw disorders. Pasture access shows a positive effect on claw health, particularly for diseases that are related to moist environments (eg, digital dermatitis). Regular documentation of claw health is a useful...

Does access to pasture affect claw condition and health in dairy cows?

The aim of this study was to examine effects of pasturing in dairy cows on claw condition (claw length, hardness) and on the prevalence of claw diseases. At claw trimming, a total of 240 Holstein-Friesian or Red-Holstein cows from 20...
