Playtime! Exploring habituation techniques in laboratory rats

Our rat training program teaches the standard method of handling and restraining that involves picking the rat up by the base of the tail and placing it on the wire mesh to be restrained. We observed that there was excessive...

Revamping porcine enrichment

Pigs may exhibit stereotypic behaviors due to lack of proper mental stimulation. Stereotypic behaviors include self-inflicted wounds, biting at the pen, polydipsia, cage destruction, and loud vocalizations. These behaviors may be alleviated with proper daily enriching stimulation. Pigs enjoy a...

Conscious urine sampling and quantification from indwelling catheterization of female Yucatan swine

In addition to routine diagnostic testing of urine for health status, data from urine collection is often necessary to support various nutritional, metabolic, biochemical, and physiologic studies. Collection methods can be stressful to the animal (manual restraint), may require sedation...

Interactive feeding technique: Elicit predatory instincts in the African clawed frog (Xenopus laevis) and grow a research colony of eaters

Xenopus laevis have a unique process for consuming food. They lack a tongue and must utilize inertial suction, jaw prehension, forearm scooping, overhead kicking, and terrestrial lunges when hunting prey. The mechanism by which Xenopus eat elicits a frenzied behavior...

Fight Club: Using housing conditions to curb male cage aggression

Those who have worked with C57BL/6 males know how aggressive they can be towards their cage mates. We poured over academic journals, reading every article we could find regarding male home cage aggression. Three articles piqued our interest and suggested...

Eureka! Enhanced water recipe and enrichment for oocyte quality and embryo development in the African clawed frog (Xenopus laevis)

Husbandry staff set a goal to develop a health monitoring program for a Xenopus laevis colony that included not only specific pathogen freedom, but wellness. This article describes environmental enrichment and a water recipe for the insurance of proper water...

Use of more naturalistic nesting material helps decrease food shredding in mice

Shredding of feed (food grinding or food wasting) is a common behavior among certain strains of mice. It is seen in both captive and wild rodents and may either be an abnormal behavior or a normal behavior that is simply...

Development of edible environmental enrichment objects for weaned pigs

Studies on environmental enrichment for weaned pigs have predominantly focused on stimulating exploration through “nonedible toys.” The research on edible enrichment objects is very limited. For this reason, the aim of this study was to develop and characterize edible environmental...

The use of synthetic grass as a novel substrate within veterinary practice canine inpatient elimination enclosures

Dogs form toileting preferences that may influence canine elimination behaviors. This study aimed to assess the effect of providing a novel substrate (synthetic grass) on indices of canine willingness to eliminate, plus associated behavioral parameters. At a veterinary hospital, an...

Facial expression of pain in Nellore and crossbred beef cattle

Although the science of facial expression of pain in humans is advanced, it has not been extensively explored in nonhuman animals. The study of facial expression as an indicator of pain might represent a substantial advance in pain recognition and...
