Investigating optimal levels of platform perch provision for windowed broiler housing

Broiler chickens show a preference for platform perches over traditional bar perches. Further information is needed on the optimal provision of these perches in order for them to be successfully installed in commercial systems. This study was designed to compare...

The effect of qualitative feed restriction in broiler breeder pullets on fear and motivation to explore

Restrictively fed broiler breeders are known to have increased motivation to explore and reduced fearfulness because hunger increases the motivation to search for and to acquire food, forcing the birds to face and engage with aversive stimuli that they would...

The power of a positive human–animal relationship for animal welfare

Domestic animals often seek and enjoy interacting with humans. Positive human–animal relationships can elicit positive emotions and other positive welfare outcomes. Nevertheless, our understanding of the underlying processes that govern the positive perception of humans by animals is incomplete. We...

Assessment of non-contact infrared thermometer measurement sites in birds

The standard method of obtaining body temperature in a bird can be a stressful event, making routine evaluations challenging. Twenty-eight privately owned birds in good health were enrolled in the study to compare digital and infrared (IR) temperature readings. Digital...

Broiler chicks’ motivation for different wood beddings and amounts of soiling

In the wild, excreta soiled surroundings can attract predators and spread disease. Yet, farmers rear broiler chicks in large barns with stocking densities that prevent excreta segregation. To measure chicks’ motivation to access unsoiled bedding or soiled litter (collectively, substrates)...

Development and validation of broiler welfare assessment methods for research and on-farm audits

Required auditing of on-farm broiler welfare in the United States has increased; however, a lack of validated tools exists for assessment of enrichment. National Chicken Council (NCC) guidelines were used on a subset of 300 Ross 308 broilers out of...

Efficient, effective, reusable, and customizable social housing for chickens in the laboratory

The Iowa State University Laboratory Animal Resources Department needed caging specifically designed and purposed to socially house chickens in the laboratory. As indoor housing requests for chickens increased, the need for a dedicated caging system for chickens became a high...

Floor substrate preferences of chickens: A meta-analysis

Environmental enrichment promotes sensory and motor stimulation for species-typical behaviors, which in turn enhance animal well-being. For farmed Galliformes, housing systems often limit enrichment to bedding and litter, that simultaneously act as material for dustbathing and foraging. Therefore, this meta-analysis...

Hens with benefits: Can environmental enrichment make chickens more resilient to stress?

Resilience, the degree to which individuals are physiologically and behaviourally impacted by stressors, can be enhanced by positive experiences (e.g. positive moods in human, environmental enrichment in rodents). Such effects are important for human health, but could also have important...

How does ultraviolet light affect layer production, fear, and stress

The lighting spectrum used in modern poultry production commonly lacks significant amounts of ultraviolet light; however, poultry can perceive the ultraviolet spectrum unlike humans and little research has been done to investigate the importance of this part of the spectrum...
