Evaluation of the effects of space allowance on measures of animal welfare in laboratory mice

We studied how space allowance affects measures of animal welfare in mice by systematically varying group size and cage type across three levels each in both males and females of two strains of mice (C57BL/6ByJ and BALB/cByJ; n = 216...

Effect of housing density on growth, agonistic behaviour, and activity in hatchling saltwater crocodiles (Crocodylus porosus)

The purpose of this study was to examine the effect of density on growth rate, agonistic behaviour, activity and use of space by hatchling C. porosus in captivity. Hatchling C. porosus were raised in identical enclosures (1.5m2) at different densities...

Effect of environmental enrichment and composition of the social group on the behavior, welfare, and relative brain weight of growing rabbits

The objective of the study was to investigate if environmental enrichment and the composition of the social group would affect the behavior and relative brain weight of growing rabbits. Rabbits (72 males and 72 females) were assigned to cages with...

A novel method for the analysis of social structure allows in-depth analysis of sow rank in newly grouped sows

Chronic stress response in fearful animals can result in depression of growth and reproductive performance. It is therefore important to be aware of at risk animals in the herd. Thus far ‘hierarchy' calculations have involved the use of fights won...

The association between infrared thermal imagery of core eye temperature, personality, age and housing in cats

Understanding individual responses to stress is a key aspect of maintaining optimal animal welfare. This is especially important where animals are being kept in sub-optimal environments or where the species may not clearly demonstrate stress. Therefore, the aim of this...

Associations between the dominance status and sexual development, skin lesions or feeding behaviour of intact male pigs

In boars, social relationships could influence pubertal development and feeding behaviour. The objectives of the present study were to determine the relationships between behaviour (agonistic, mounting and feeding behaviours), plasma sex steroids (oestradiol, testosterone) and fat androstenone. A total of...

The effect of auditory enrichment, rearing method and social environment on the behavior of zoo-housed psittacines (Aves: Psittaciformes); implications for welfare

The psychological and physiological effects of different genres of music are well documented in humans. These concepts have also been studied in kenneled dogs and some exotic animals, implying that animals may experience benefits similar to those of humans. This...

A synthetic olfactory agonist reduces aggression when sows are mixed into small groups

Synthetic olfactory agonists mimic odours secreted by mammary glands in several mammal species and their application can reduce anxiety levels in both juvenile and adult animals. This investigation determined the effect of a commercially available synthetic olfactory agonist administration on...

Aggressive behaviour at regrouping is a poor predictor of chronic aggression in stable social groups

Commercial pigs globally are routinely mixed into new social groups. This results in regrouping aggression predominantly during the first 24h which compromises welfare and productivity. Chronic aggression persists thereafter and is also undesirable. Management strategies are needed that reduce the...

Less water renewal reduces effects on social aggression of the cichlid Pterophyllum scalare

Changes in aquatic environments can affect fish behavior. Water renewal, for example, can dilute chemical signals, which are a social communication tool used by some fish species, and this dilution increases aggressive interactions in the group. Fierce and prolonged fights...
