Abstract

All poultry species live in groups. These groups can change in structure and composition depending on the season, group size, or availability of resources. Living in groups protects animals from predators and facilitates finding new resources, among other benefits. But living in groups also has...

Abstract

For captive animals, group sizes and/or densities are established by humans based on criteria that range from enclosure size to experimental needs or economic reasons. Because group sizes in farm, zoo and laboratory animals are the result of human decisions, it is important to highlight the...

Abstract

Farm animals are social species with a strong tendency to form groups. Living in groups has associated costs and benefits. The costs refer mostly to competition for food, or access to other valuable resources that may lower the individuals' fitness, while the benefits includes (but are not limited...

Abstract

Provision of adequate housing is essential to assure the welfare of farm animals. One relevant aspect is space allowance, due to potential consequences on the behaviour and welfare of animals. The objective of this study was to determine the effect of space allowance on the behaviour and potential...

Abstract

The grazing dynamics of animals differ depending on whether they are raised on rangeland or sward areas. Grazing patterns of cattle raised on rangeland can be modified by the location of supplement feed and water troughs. However, no information about the use of this strategy is available for...

Abstract

The aim of this review is to discuss the impact of group size on damaging behaviours, aggression, fear and stress in farm animals and to identify housing- and management options that can help to reduce problems caused by suboptimal group sizes. Increasing group size was found to increase the risk...

Abstract

Animal group sizes may exert important effects on various cognitive mechanisms. Group size is believed to exert pressures on fundamental brain structures that correlate with the increased social demands placed on animals living in relatively large, complex and dynamic social organizations. There is ...

Abstract

With the development of laboratory animal science, increasing attention has been given to the possible influence of housing and husbandry on the behaviour and welfare of laboratory animals as well as on the scientific integrity. With the present paper, we aim to contribute to this knowledge by...

Abstract

Group size is one of the most important factors influencing the formation and maintenance of successful social groups in captivity. For zoos, appropriate social groupings are of the utmost importance to provide examples of species-typical behaviors, as well as attain captive breeding goals. In the...

Abstract

In modern rearing systems, turkey producers often face economic losses due to increased aggression, feather pecking, cannibalism, leg disorders, or injuries among birds, which are also significant welfare issues. The main underlying causes appear to relate to rapid growth, flock size, density, poor ...
