Bedding system influences lying behaviour in dairy cows

Background: The nature and depth of bedding material have an important influence on cow lying behaviour and comfort. Increasing use of recycled manure solids (RMS) as bedding led to an investigation of the influence of this material on cow lying...

The impact of environmental enrichment on red-eared slider turtles (Trachemys elegans)

This study aimed to determine whether tank enrichment improved positive species-specific behaviors (those that benefit the animals' overall well-being), such as basking, and/or decreased negative behaviors (those that may indicate stress, agitation, or discomfort), such as dragging limbs, in red-eared...

To stay virtual or not to stay virtual? That is the question

Both the Office of Laboratory Animal Welfare (OLAW) and the U.S. Department of Agriculture (USDA) released guidance about how to conduct inspections during the pandemic; some of their suggestions may be of value to retain as hybrid approaches (virtual and...

Effects of hair removal creams on mouse skin

Human hair removal brands such as Nair™ are sometimes used in research to remove hair from mice before surgery, imaging, and other procedures.1,3 While the use of these depilatory creams in rodent research is relatively widespread, few studies have evaluated...

Improving maternal welfare during gestation has positive outcomes on neonatal survival and modulates offspring immune response in pigs

Improving the housing of pregnant sows by giving them more space and access to deep straw had positive effects on their welfare, influenced their maternal behavior and improved the survival of their offspring. The present study aimed at determining whether...

Stereotypic behaviors are associated with physiology and immunity differences in long-term confined sows

Pregnant sows in the confined environment have poor welfare and frequently perform stereotypic behaviors. In order to clarify whether highly stereotypic behavior is a sign of increased stress and successfully contributes to coping with or adaptation to adverse environment, fifty...

Eye surface infrared thermography usefulness as a noninvasive method of measuring stress response in sheep during shearing: Correlations with serum cortisol and rectal temperature values

During shearing, animals' welfare is adversely affected and acute stress occurs. Once animal perceives a threat, it develops behavioral, autonomic, endocrine or immune responses to maintain homeostasis. This study aimed to investigate the usefulness of eye temperature assessment by infrared...

Effects of buprenorphine on model development in an adjuvant-induced monoarthritis rat model

Complete Freund's adjuvant (CFA)-induced arthritis in rats is a common animal model for studying chronic inflammatory pain. However, modelling of the disease is associated with unnecessary pain and impaired animal wellbeing, particularly in the immediate post-induction phase. Few attempts have...

Effects of non-aversive versus tail-lift handling on breeding productivity in a C57BL/6J mouse colony

Non-aversive handling is a well-documented refinement measure for improving rodent welfare. Because maternal stress is related to reduced productivity, we hypothesized that welfare benefits associated with non-aversive handling would translate to higher production and fewer litters lost in a laboratory...
