Assessment of the safety and efficacy of pre-emptive use of extended-release buprenorphine for mouse laparotomy

Buprenorphine is commonly used to control postoperative pain in rodents. Short-acting formulations of buprenorphine (bup-HCl) require frequent handling and restraint of animals for appropriate dosing, which can be stressful and confound research outcomes. Ethiqa XR (bup-ER) is an FDA-indexed extended-release...

Housing and husbandry alternatives for naked mole rat colonies used in research settings

Naked mole rats (Heterocephalus glaber) are a unique rodent species originating in Africa and are increasingly being used in research. Their needs and characteristics differ from those of other rodents used in research. Unique housing systems are necessary to address...

Efficacy of lidocaine topical solution in reducing discomfort reaction of horses to intramuscular vaccination

Vaccinations via intramuscular injection are a key component of preventative health care in horses. Development of problematic behavioral aversion to injections is quite common. Our clinical impression has been that topical anesthetic applied to injection sites can reduce the behavioral...

The promise of behavioral tracking systems for advancing primate animal welfare

Recent years have witnessed major advances in the ability of computerized systems to track the positions of animals as they move through large and unconstrained environments. These systems have so far been a great boon in the fields of primatology,...

Effects of housing system on anxiety, chronic stress, fear, and immune function in Bovan brown laying hens

The scientific community needs objective measures to appropriately assess animal welfare. The study objective was to assess the impact of housing system on novel physiological and behavioral measurements of animal welfare for laying hens, including secretory and plasma Immunoglobulin (IgA;...

Video conference technology as a tool for pair introduction in rhesus macaques

Pair housing is known to promote welfare for macaques in captivity. However, finding compatible partners can be challenging, particularly when animals are not located near one another. Because macaques show interest in videos of conspecifics, we examined the use of...

Assessment of indoor air quality for group-housed macaques (Macaca spp.)

Indoor Air Quality (IAQ) is strongly associated with animal health and wellbeing. To identify possible problems of the indoor environment of macaques (Macaca spp.), we assessed the IAQ. The temperature (°C), relative humidity (%) and concentrations of inhalable dust (mg/m3),...

Increasing environmental complexity by providing different types of litter and perches during early rearing boosts coping abilities in domestic fowl chicks

Early experience of a complex environment can improve biologically relevant traits related to coping abilities. However, the mechanisms underlying these positive effects have not been well explored. We hypothesized that giving chicks possibilities to express choices within relevant resources could...

Environmental enrichment as part of the improvement of the welfare of Japanese quails

The aim of this study was to evaluate the indicators of the behavioural and physiological welfare of Japanese quails (Coturnix japonica) as possible responses to the enrichment of the birds' habitat. The study sample consisted of 280 Japanese quails (224...
