Dairy cows value access to pasture as highly as fresh feed

Many dairy cows in the developed world are now housed exclusively indoors with fewer than 5% of the 10 million lactating cows in the United States having access to pasture during the grazing season. Indoor housing systems are designed to...

The importance of burrowing, climbing and standing upright for laboratory rats

Standard laboratory cages prevent rats (Rattus norvegicus) from performing many behaviours that they perform in the wild, but little is known about how this may affect their welfare. The aims of this study were (i) to record the propensity to...

Impact of daily grazing time on dairy cow welfare—results of the Welfare Quality® protocol

Grazing provides livestock better opportunities to act out their species-specific behavior compared to restrictive stable conditions. The aim of the present study was to examine the effects of daily grazing time on welfare of dairy cows in organic and conventional...

Unbridle biomedical research from the laboratory cage

Many biomedical research studies use captive animals to model human health and disease. However, a surprising number of studies show that the biological systems of animals living in standard laboratory housing are abnormal. To make animal studies more relevant to...

Naturalness and animal welfare

Naturalness is considered important for animals, and is one criterion for assessing how we care for them. However, it is a vague and ambiguous term, which needs definition and assessments suitable for scientific and ethical questions. This paper makes a...

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...
