Impacts of temperature on the growth, feed utilization, stress, and hemato-immune responses of cherry salmon (Oncorhynchus masou)

Cherry salmon (Oncorhynchus masou) hold commercial value in aquaculture, and there is a need for controlled laboratory studies to isolate the specific effects of temperature on their growth, feeding, and well-being. We examined the effects of different temperatures (10 °C,...

Social context increases ultrasonic vocalizations during restraint in adult mice

Adult mice emit many ultrasonic vocalizations (USVs) during social interaction tasks, but only a few studies have yet reported USVs in stressed adult mice. Our aim was to study which experimental conditions favor USV emission during behaviors associated with different...

Evaluation of targeted injections of ivermectin or potassium chloride for euthanasia of anesthetized thorny devil stick insects (Eurycantha calcarata)

Insects are commonly utilized in biomedical research and have become increasingly popular in museum collections and as pets. Despite this, objective evaluation of insect euthanasia is scarce. This study investigated the effectiveness of targeted injections of ivermectin or potassium chloride...

Euthanasia complications in non-domestic species

There are very few studies describing euthanasia complications in non-domestic species. The goal of this study was to survey veterinarians to determine what complications may commonly occur during the euthanasia of non-domestic species. An online survey was sent to seven...

Choice, control, and animal welfare: Definitions and essential inquiries to advance animal welfare science

The ways in which humans can support good welfare for animals in their care is an ongoing subject of debate: some place emphasis on the animals' physical health; others, on animals' ability to live “natural lives”; and others on animals'...

CIRS-LAS – a novel approach to increase transparency in laboratory animal science for improving animal welfare by reducing laboratory animal distress

The 3Rs principle is highly topical in animal-based research. These include, above all, new scientific methods for conducting experiments without an animal model, by using non-animal models (Replace), reducing the number of laboratory animals (Reduction) or taking measures to keep...

Sex, age, and individual differences in bottlenose dolphins (Tursiops truncatus) in response to environmental enrichment

Application of environmental enrichment, as a means to successfully decrease undesired behaviors (e.g., stereotypic) and improve animal welfare, has been documented in a variety of zoological species. However, a dearth of empirical evidence exists concerning age, sex, and individual differences...

Moving away from soiled bedding sentinels—The (R)evolution in rodent health screening

Traditional health monitoring methods consist of Soiled Bedding Sentinels (SBS), with animals exposed to dirty bedding from colony animals, which require the euthanasia of SBS. Numerous studies have demonstrated that SBS may not accurately represent a colony's health status. During...

Why it hurts: With freedom comes the biological need for pain

We argue that pain is not needed to protect the body from damage unless the organism is able to make free choices in action selection. Then pain (including its affective and evaluative aspects) provides a necessary prioritising motivation to select...

Reaction to novel objects and fecal glucocorticoid metabolite levels in two species of nocturnal geckos

Many reptiles are maintained in captivity and heavily traded, although welfare measures for many species are not well established and are under-researched compared to other animals. In this study, we focused on two of these species: crested geckos (Correlophus ciliatus)...
