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...

Is harbor porpoise (Phocoena phocoena) exhaled breath sampling suitable for hormonal assessments?

Over the last decades, exhaled breath sampling has been established for laboratory analysis in various cetacean species. Due to their small size, the usability of respiratory vapor for hormone assessments was questionable in harbor porpoises (Phocoena phocoena). This pilot study...

Strategies to encourage the adoption of social housing during cardiovascular telemetry recordings in non-rodents

The National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) is working with industry to promote social housing during cardiovascular telemetry recordings within non-rodent safety pharmacology and toxicology studies. Following surveys to capture current practice, benefits...

Facial thermography is not useful in assessing body temperature in common squirrel monkeys (Saimiri sciureus) in comparison to rectal temperatures

A group of 39 captive common squirrel monkeys (Saimiri sciureus) had their body temperature measurements compared by rectal thermometry and facial infrared thermal imaging (Flir i3, Flir Systems Inc). Squirrel monkeys were caught up and manually restrained for examination and...

Assessment of a noninvasive chronic glucose monitoring system in euglycemic and diabetic swine (Sus scrofa)

Models of type-I diabetes are well-characterized and commonly used in the preclinical evaluation of drugs and medical devices. The diabetic minipig is an excellent example of a translational model. However, chronic glucose monitoring in this species can be challenging; frequent...

Analysis of hair cortisol as an indicator of chronic stress in pigs in two different farrowing systems

Confinement to farrowing crates is known to prevent sows from performing natural behavior, impairing animal welfare and possibly causing chronic stress. Hair cortisol analyses are increasingly used to detect chronic stress in animals. In the present study, hair samples were...
