A comparative study on two territorial fishes: The influence of physical enrichment on aggressive behavior

Intraspecific aggression is detrimental to body/fin damage, physiological stress, and other problems in aquaculture. Environmental enrichment has been proposed to have positive effects on fish aggressive behavior, physiological stress, and fish welfare, but there are mixed results. Here, we examine...

Suitability of different thermometers for measuring body core and skin temperatures in suckling piglets

Monitoring the temperature of piglets after birth is critical to ensure their well-being. Rectal temperature measurement is time-consuming, requires fixation of the animal and is stressful for piglets. This study aims to evaluate the effectiveness of infrared thermometry and thermography...

Refinement of animal model of colorectal carcinogenesis through the definition of novel humane endpoints

This study aimed to define appropriate humane endpoints (HEs) for an animal model of colorectal carcinogenesis (CRC). Twenty-nine male Wistar rats were divided into two control groups (CTRL1 and CTRL2) injected with ethylenediamine tetraacetic acid (EDTA)–saline solutions and two induced...

Effect of environmental enrichment on the brain and on learning and cognition by animals

The humane treatment of animals suggests that they should be housed in an environment that is rich in stimulation and allows for varied activities. However, even if one's main concern is an accurate assessment of their learning and cognitive abilities,...

Retrospective analysis of the effectiveness and reversibility of long-acting contraception Etonogestrel (Implanon®) in common marmosets (Callithrix jacchus)

Contraception is an important population control method for the colony management of primates housed in captivity. Etonogestrel (ENG) implants (i.e., Implanon®) are a widely used progestin-based contraceptive in common marmosets (Callithrix jacchus) with the theoretical advantages of being reversible and...

Evaluation of potential sustainable bedding substrates focusing on preference, behavior, and stress physiology in rats—A pilot study

Ensuring optimal housing conditions for laboratory animals is a crucial prerequisite for high-quality and ethically justifiable in vivo science. In addition to guaranteeing animal welfare and promoting scientific validity, environmental sustainability is also increasingly gaining attention in laboratory animal facilities....

Enhanced understanding of horse–human interactions to optimize welfare

Horses (Equus caballus) have been domesticated for millennia and are regularly utilized for work, sport, and companionship. Enhanced understanding of human–horse interactions can create avenues to optimize their welfare. This review explores the current research surrounding many aspects of human–horse...
