Assessment of preference behavior of layer hens under different light colors and temperature environments in long-time footage using a computer vision system

As for all birds, the behavior of chickens is largely determined by environmental conditions. In many production systems, light intensity is low and red feather strains have low contrast with the background, making it impossible to use conventional image segmentation...

Lateralised behavioural responses in livestock to environmental stressors: Implications for using infrared thermography to assess welfare conditions

Lateralised behavioural responses to environmental stressors have become more frequently used as indicators of social welfare in animals. These lateralised behavioural responses are under the control of asymmetrical brain functions as part of the primary functions of most vertebrates and...

A practical approach to providing environmental enrichment to pigs and broiler chickens housed in intensive systems

In Europe, regulations contain guidance to maintain high standards of animal welfare. In many parts of the world, large buyers for supermarkets or restaurants are the main enforcers of basic animal welfare standards. They can have considerable influence on improving...

Influence of perch-provision timing on anxiety and fearfulness in laying hens

Perches can enhance laying hen welfare, but their effectiveness might be age-dependent. We investigated early and late perch access effects on anxiety and fear in pullets through attention bias (AB) and tonic immobility (TI) tests. Pullets (n = 728) were...

A buffet of litters – Broiler chickens behave differently according to litter type and freshness

Poultry are usually provided with a single litter type that may not satisfy all litter-directed behavioural functions and may lose functional value over time due to soiling and degradation. We investigated this hypothesis in two commercial broiler flocks reared to...

Better welfare for broiler chickens given more types of environmental enrichments and more space to enjoy them

Providing an increased variety of environmental enrichment options, with sufficient space to use them, could increase the behavioural expression of positive affective states in production animals. The goal of this study was to investigate associations between the number of different...

Animal agency, animal awareness and animal welfare

In nature, animals need to actively engage with the environment in order to prosper in survival and reproduction. Hence, agency is a central adaptive characteristic of animal life. In this paper, I propose that from the adaptive/functional point of view,...

Poultry welfare: Science or subjectivity? British Poultry Science 43(5), 643–652

1. Most people in the developed world agree on what “animal welfare” is, although it is impossible to give it a precise scientific definition. 2. The argument is made that animal welfare is all to do with the feelings of...

Farm animal enrichments improve the welfare of layer chicks and pullets: A comprehensive review

Currently, cage housing is regarded as a global mainstream production system for laying hens. However, limited living space and confinement of birds in cages cause welfare and health problems, such as feather pecking, osteoporosis, obesity, and premature aging. Many studies...

Environmental change or choice during early rearing improves behavioural adaptability in laying hen chicks

Laying hens are typically moved to a novel environment after rearing, requiring adaptability to cope with change. We hypothesized that the standard rearing of laying hen chicks, in non-changing environments with limited choices (a single variant of each resource), impairs...
