Improving rat welfare through the development of a peribulbar anaesthesia technique for ophthalmic procedures: A preliminary study

Rats are a commonly used animal model for the study of the pathogenesis and novel treatments of glaucoma, which is induced experimentally using invasive, painful procedures. Peribulbar anaesthesia (PBA) is frequently used in people and domestic animals prior to ophthalmic...

Rats prefer condensed milk to strawberry jam – a new possibility for voluntary oral drug administration

Voluntary oral drug administration using sweet substances promotes rodents' therapeutic compliance while reducing stress induced by forced drug administration. We aimed to test whether rats would willingly eat strawberry jam or condensed milk from a syringe, and which one they...

Environmental conditions shape learning in larval zebrafish

Growing evidence reveals notable phenotypic plasticity in cognition among teleost fishes. One compelling example is the positive impact of enriched environments on learning performance. Most studies on this effect have focused on juvenile or later life stages, potentially overlooking the...

Paper towel shredding as a novel, affordable, noninvasive method for detecting arousals in hibernating rodents

Many research groups explore the regulation of hibernation or compare the physiology of heterothermic mammals between the torpid and aroused, euthermic states. Current methods for monitoring torpor (for example, infrared cameras, body temperature or heart-rate telemetry, and motion sensing) are...

Differences in fluid, electrolyte, and energy balance in C57BL/6J mice (Mus musculus) in metabolic caging at thermoneutral or standard room temperatures

The Guide for the Care and Use of Laboratory Animals recommends mice be pair or group housed and provided with nesting materials. These provisions support social interactions and are also critical for thermoregulatory behaviors such as huddling and burrowing. However,...

Disentangling developmental effects of play aspects in rat rough-and-tumble play

Animal play encompasses a variety of aspects, with kinematic and social aspects being particularly prevalent in mammalian play behaviour. While the developmental effects of play have been increasingly documented in recent decades, understanding the specific contributions of different play aspects...

Anesthesia and humane euthanasia methods for king worm larvae (Zophobas morio)

A growing spotlight on insect welfare as research subjects, fodder for vertebrate animals, and patients for veterinarians highlights the need to establish humane euthanasia methods for these species. An insect of increasing commercial importance is the king worm (Zophobas morio),...

The protective effect of social support: Can humans reassure pigs during stressful challenges through social learning?

Farm animals can socially learn to trust a human after observing that human handling a familiar conspecific gently, even if they never positively interacted with the human themselves. This study aimed to evaluate whether pigs are reassured by a human...

Social reinforcement guides operant behaviour and auditory learning in a songbird

Motivation to seek social interactions is inherent to all social species. For instance, even with risk of disease transmission in a recent pandemic, humans sought out frequent in-person social interactions. In other social animals, socialization can be prioritized even over...

Sleep quality in cynomolgus macaques (Macaca fascicularis) varies by housing type and following surgery

Sleep is an important contributor to good physical and mental health and an important component of post-surgical recovery. The assessment of dark phase (‘nighttime') behavior can provide insight into the efficacy of analgesic treatments and should be considered when assessing...
