An opportunistic study to assess African green monkey (Chlorocebus sabaeus aethiops) welfare using novel and classical biomarkers

The care and well-being of nonhuman primates (NHPs) in biomedical science have benefited from species-specific enrichment research. However, there remain few publications on African green monkey (AGM) welfare and husbandry. This opportunistic study aimed to explore the use of novel...

The impact of enriched housing on the behaviour and welfare of captive leopard geckos (Eublepharis macularius)

Substantial evidence demonstrates the benefits of environmental enrichment in mammals and birds. However, far less is known about this topic in reptiles—an increasingly popular group of pets. This study compared the effects of housing conditions (Standard vs. Enriched) on the...

Gavage-needle voluntary consumption administration of a dose-specific measure to mice (Mus musculus)

Orogastric gavage is a common technique used to administer test articles to rodents with risks ranging from increased stress to death of the animal. In this study, we propose a novel technique to administer treatments to mice for voluntary consumption...

Establishing a predictable cue for catches to reduce reactivity to management events for captive rhesus macaques (Macaca mulatta)

Psychological duress can emerge from the perceived lack of predictability such that, in captive circumstances, reliable signals for aversive events can afford animals with the opportunity to behaviorally and physiologically prepare. Does a reliable and unique signal cue for an...

Evaluation of welfare indicators for companion parrots: A Delphi consultation survey

Parrots can experience several welfare challenges when kept as companions. Despite their popularity no science-based guidelines are available to assess parrot welfare. The aim of this Delphi study was to establish consensus on welfare indicators that could be meaningful and...

Effects of light colour and intensity on stress responses in the Pacific white shrimp (Penaeus vannamei).

Stress is a natural defence mechanism that can negatively impact the outcome of experiments and increase interindividual variability. Among environmental parameters, light colour and intensity are known to impact stress responses in numerous species. The Pacific white shrimp Penaeus vannamei...

Increasing cage complexity reduces abnormal behaviours in farmed blue foxes

We studied the long-term effects of biweekly rotated enrichment objects and a permanent shelter screen on abnormal behaviour, daily activity, and stress physiology in juvenile female blue foxes (aged 3–9 months). The experiment lasted seven months, from August to February, following...

Behavioral and performance effects on female offspring from rabbit does housed in enriched cages during gestation and lactation

In mammals, intrauterine experiences and early-life conditions can influence future behaviors. This study aimed to evaluate the impact of enriched and conventional cages for rabbit does during gestation and lactation on the behavior and performance of the first generation of...

Evaluating outcomes of diazepam administration in gradual steps introductions of adult male and female rhesus macaques (Macaca mulatta)

Social housing remains one of the best forms of environmental enhancement for nonhuman primates (NHPs). The gradual steps (GS) method, a 2-step plan involving an initial phase of limited physical contact (protected contact [PC]) prior to full contact (FC), is...

Biopolymer-based nesting material for sows and its consequence on nest-building behavior, farrowing kinetics and piglet vitality

In the present study, we evaluated the effects of a soluble and biodegradable biopolymer-based material, structurally resembling natural fiber, as an alternative nesting-material for prepartum gilts. A total of 18 first parity sows and their litters were studied. One hour...
