3Rs improvements in the Bexsero® (Meningitis B) vaccine

Bexsero® is a new vaccine in the UK which since September 2015 has been added to the childhood immunisation programme for the prevention of Meningitis B. The in-vivo test as performed in Biological Services Division (BSD) uses female CD1 mice...

Refining the palpation technique to improve monitoring in the transgenic mouse

We have developed an accurate method of detecting and monitoring internal ovarian tumours. This reduces the number of procedures, refines the way we detect internal tumours and defines an end point before animals become visibly sick. The problems with the...

Development of a body condition score for the mountain chicken frog (Leptodactylus fallax)

The Critically Endangered mountain chicken frog (Leptodactylus fallax) has undergone drastic population decline due to habitat loss, hunting, invasive species, and chytridiomycosis. In response, several partner institutions initiated a conservation breeding program. It is important to maintain the captive population...

Cognitive judgement bias is associated with frequency of anticipatory behavior in bottlenose dolphins

Many animals display a suite of increased vigilance and/or activity responses in relation to upcoming events, termed “anticipatory behavior.” Anticipatory behavior toward positive events has been suggested as a cross‐species measure of affective state as it likely reflects the balance...

Vocal correlates of emotional reactivity within and across contexts in domestic pigs (Sus scrofa)

Vocalizations have long been recognized to encode information about an individual's emotional state and, as such, have contributed to the study of emotions in animals. However, the potential of vocalizations to also encode information about an individual's emotional reactivity has...

Fecal glucocorticoid metabolite responses to management stressors and social change in four species of callitrichine monkeys

The use of enzyme immunoassays (EIA) for the non-invasive measurement of glucocorticoids provides a valuable tool for monitoring health and welfare in sensitive species. We validated methods for measuring fecal glucocorticoid metabolites (FGM) using the response to veterinary exams for...

The biology and husbandry of the African spiny mouse (Acomys cahirinus) and the research uses of a laboratory colony

African spiny mice (Acomysspp.) are unique precocial rodents that are found in Africa, the Middle East, and southern Asia. They exhibit several interesting life-history characteristics, including precocial development, communal breeding, and a suite of physiologic adaptations to desert life. In...

Assessing animal affect: An automated and self-initiated judgement bias task based on natural investigative behaviour

Scientific methods for assessing animal affect, especially affective valence (positivity or negativity), allow us to evaluate animal welfare and the effectiveness of 3Rs Refinements designed to improve wellbeing. Judgement bias tasks measure valence; however, task-training may be lengthy and/or require...

Body temperature measurement in mice during acute illness: Implantable temperature transponder versus surface infrared thermometry

Body temperature is a valuable parameter in determining the wellbeing of laboratory animals. However, using body temperature to refine humane endpoints during acute illness generally lacks comprehensiveness and exposes to inter-observer bias. Here we compared two methods to assess body...

Fish sentience denial: Muddying the waters

Recent empirical studies have reported evidence that many aquatic species, including fish, cephalopods and crustaceans, have the capacity for nociception and pain, and that their welfare should be taken into consideration. Some sceptics, rejecting the precautionary principle, have denied that...
