Relative preference for different pecking blocks offered as pairwise comparisons in White and Brown-feathered laying hens

Different commercially available pecking blocks (PBs) have varying nutrient composition, appearance, and texture. However, the relative preferences of laying hens for different PBs are unknown. We housed 120 Dekalb White and 120 Bovans Brown in twelve (360 cm x 116 cm x...

Behavioral Biology of Laboratory Animals

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Meta-analysis on the effect of foraging on feather pecking and feather coverage

Feather pecking (FP) has been a longstanding concern in avian welfare because of its potential to inflict harm on bird plumage. Researchers have proposed the redirection hypothesis in studies investigating factors influencing FP, positing that pecking feathers serve as a...

A gentling program decreases fear-related behaviour towards humans but not towards novel objects in broiler chickens

The human-animal-relationship is a crucial aspect of good animal welfare. Improvements in this regard might be particularly relevant for chickens, as their relationship with humans in commercial husbandry conditions is often limited to brief animal inspections (visual contact) on a...

Assessing the motivation of laying hens to outdoor space access

The present study aimed at evaluating the motivation of laying hens to access outdoor space and their behavior under indoor and outdoor conditions. A total of 54 laying hens (White Leghorns) at 38 weeks of age were housed in two...

Smart farming and Artificial Intelligence (AI): How can we ensure that animal welfare is a priority?

The increasing use of technology in livestock farming has the potential for making farming easier and more efficient and for improving animal welfare. There are also, however, potential dangers, one of which is that animal welfare becomes subordinated to the...

Social learning during human-animal interaction: Effects on broiler chickens’ behavior

Human-animal interactions play a great role in animal welfare. Despite that chickens can establish positive bonds with humans, it remains unknown if broiler chickens can do this via social learning. This study examined whether observing conspecifics undergoing gentle handling (demonstrator...

Social enrichment improves affective state and foraging behavior compared to physical enrichment, while maintaining growth performance in broiler chickens

Environmental enrichment is key for improving the broiler welfare in intensive production systems. This study lasted for 43 days and evaluated the effects of physical and social enrichment on broiler welfare. A total of 96 one-day-old male broilers were divided...
