How should one design and position straw feeders in group-housed horses? A case study on occupancy and agonistic interactions at straw feeders in a large group of horses

As group housing of horses can be associated with increased injury risk especially when there are limited resources, the aim of this study was to allow initial, scientifically based recommendations regarding the positioning and design of straw feeders. Data collection...

Lighting and behaviour in captivity: Butterflies prefer light environments containing UV wavelengths

The behaviour and welfare of animals in captivity is of great importance to zoological collections, captive breeding programmes, food production and keepers of companion animals. Artificial lighting is commonly deficient in UV wavelengths, and use of such lighting for indoor...

Puzzle feeder as a cognitive enrichment strategy determines long-term welfare improvements in a teleost fish

Providing access to cognitive tasks, such as puzzle feeders, holds promise as enrichment strategy to enhance the welfare of captive animals. Despite the substantial number of teleost fish in captivity, the effects of cognitive enrichments in this group remain relatively...

Moving vs still prey: Do common wall lizards show any preference?

Among prey functional traits, mobility plays a major role, affecting its actual availability to predators: a moving animal is usually more susceptible of being detected than immobile or inanimate prey. With the aim of investigating the role played by visual...

Improving effectiveness of environmental enrichment: The role of light intensity in rock bream (Oplegnathus fasciatus) rearing

Environmental enrichment is a potential approach to enhance the fitness and survival of hatchery fish stocked for conservation purposes. Its effectiveness presumably depends not only on ecologically relevant features of physical enrichment but also on light condition applied. Despite the...

Reducing hay waste from New Zealand white rabbits (Oryctolagus cuniculus) by switching to hanging wire feeders from conventional food bowls

Rabbits require daily dietary fiber (hay) to help maintain a healthy digestive tract. As per our standard operating procedure (SOP), we give the rabbits hay and other daily food enrichment in a bowl. Rabbits are intelligent, playful, and curious animals...

A new laboratory research model: The Damaraland mole-rat and its managed care

The Damaraland mole-rat (Fukomys damarensis) is a subterranean, hypoxia-tolerant, long-lived rodent endemic to southern and central Africa that is increasingly being used in laboratory research. Its husbandry needs and characteristics differ from traditional rodent research models. Here, we provide a...

Moving toward evidence-based care: Measuring preferences in zoo-housed aquatic turtles using 24-h remote monitoring

Providing evidence-based care to animals is a common goal in zoos and aquariums. However, there are many understudied species with a lack of information available, which may result in suboptimal care for individuals of these species. Using preference tests to...

Effect of adopting a timothy hay–based diet at weaning or in adulthood on urinary tract parameters in strain 13/N guinea pigs (Cavia porcellus)

Type of feed is an important consideration in herbivore colony management, yet limited studies report on the effects of diet on common conditions such as urolithiasis in guinea pigs. Urolithiasis is a well-documented cause of lower urinary tract disease in...

The impact of light, noise, cage cleaning and in-house transport on welfare and stress of laboratory rats

Human interaction and physical environmental factors are part of the stimuli presented to laboratory animals everyday, influencing their behaviour and physiology and contributing to their welfare. Certain environmental conditions and routine procedures in the animal facility might induce stress responses...
