Protection of blood-brain barrier as a potential mechanism for enriched environments to improve cognitive impairment caused by chronic cerebral hypoperfusion

Chronic cerebral hypoperfusion (CCH) is a common pathophysiological basis for Alzheimer’s Disease and vascular dementia in the early stages. It has been confirmed that blood-brain barrier (BBB) destruction is a key factor in CCH-related cognitive impairment. Here we explored the...

Psychological stress, its reduction, and long-term consequences: What studies with laboratory animals might teach us about life in the dog shelter

There is a long history of laboratory studies of the physiological and behavioral effects of stress, its reduction, and the later psychological and behavioral consequences of unmitigated stress responses. Many of the stressors employed in these studies approximate the experience...

Putting our best foot forward: Care and conditioning for swine hooves

Maintaining the hooves of swine in research is vital to their health and welfare. Ideal flooring provides stable footing and a surface for wearing down the hooves. Otherwise, injuries can occur, or repeated anesthesia may be needed for regular hoof...

Quantitative and qualitative behavioral measurements to assess pain in axolotls (Ambystoma mexicanum)

Effective pain relief in animals relies on the ability to discern pain and assess its severity. However, few objective measures exist to assess the presence and severity of pain in axolotls, and few resources are available regarding drugs and appropriate...

Rearing enrichments affected ranging behavior in free-range laying hens

Within Australia, free-range systems are prevalent, but pullets destined for range access are reared indoors. This mismatch between rearing and layer housing may hinder adaptation to the free-range environment. Rearing enrichments could enhance pullet development. A total of 1,386 Hy-Line...

Relationships between rearing enrichments, range use, and an environmental stressor for free-range laying hen welfare

Enrichments during pullet rearing may improve adaptation and welfare of hens as they move from indoor rearing to a free-range system. Individual variation in outdoor ranging may also affect welfare. This study assessed the effects of rearing enrichments and an...

An Enrichment Device for Great Apes

The influence of an environmental enrichment feeding device (puzzle feeder), on activity and behaviour patterns of captive orang-utans, gorillas and chimpanzees was studied at London Zoo. General activity levels and behaviours directed towards the feeder increased for all species when...

Behaviour and Preferences Among Deep Litters in Captive Capuchin Monkeys (Cebus Capucinus)

A captive group of white-faced capuchins, Cebus capucinus, was presented with four deep litters in simultaneous choice (or preference) tests. A floor covering of ground corn cob, woodchips, wood wool or peat was presented once in each quarter of the...

In-Homecage Blood Collection from Conscious Stumptailed Macaques

Six adult female stumptailed macaques (Macaca aretoides) were trained within a two week period to actively co-operate during in-homecage venipuncture rather than in a restraint apparatus away from the homecage. The training was based on consistent firmness, gentleness and patience....
