Using machine learning and predictive artificial intelligence to determine cage change frequency for mice housed in individually ventilated cages and drive vivarium operational efficiency

A standard 2-wk cage change frequency for individually ventilated mouse cages is used in many research facilities, with negligible effects on animal health and welfare. However, these techniques rely on subjective visual evaluations and often require spot changes. In this...

The maintenance conditions of the zebrafish (Danio rerio) breeding stock affect the survival and behavior of their offspring

The environment in which we live influences our biological traits throughout our ontogeny, being markedly significant during the beginning of our lives. Some characteristics inherited (genetically and/or epigenetically) from parents can also influence individual development, known as transgenerational effects. In...

Germinating a novel idea to rodent heat support

An external heat source is frequently used to help rodents maintain optimal body temperature. The current gold standard for providing heat support to laboratory rodents is circulating warm water blankets. However, these come with certain drawbacks, including cost, the need...

The effects of artificial UV-B provision on positional sleeping behaviour and vitamin D3 metabolites of captive aye-ayes (Daubentonia madagascariensis)

Zoological environments aim to promote natural behaviours and optimal welfare conditions. Over the past decade, research on the use of artificial ultraviolet-B (UV-B) exposure has improved vitamin D3 levels and reduced incidences of metabolic bone disease in diurnal primates; however,...

Effects of enclosure size on the preferences of juvenile chinchillas (Chinchilla lanigera)

This study investigated the cage size preferences of juvenile chinchillas using enclosures that allowed free choice between different dimensions. Three comparisons were tested: (1) small floor area (0.15 m2) vs. double floor area (0.30 m2) at constant height; (2) low...

Horse vision through two lenses: Tinbergen’s Four Questions and the Five Domains

To improve human–horse interactions and reduce the risk of injury, it is essential to adopt an equi-centric perspective that prioritizes how horses perceive their environment. This review focuses on the equine visual system, both because it is the most studied...

Impact of feeding strategies on the welfare and behaviour of horses in groups: An experimental study

Finding feeding strategies that meet horses’ needs without compromising health is essential for optimising welfare, particularly in group housing, where limited hay availability increases aggression and injury risks. Recently, two strategies have emerged: portioning daily intake into smaller, frequent meals...

Evaluating the suitability of substrate enrichment for Zebrafish in high-capacity research aquaria

Zebrafish, Danio rerio, show a preference for substrate enrichment within their tanks however this is seldom included within high-capacity research aquaria due to fears its inclusion may impact on their ability to breed on demand. To investigate this potential impact...

Husbandry and management interventions for the conservation and welfare of captive animals – a systematic evidence map

Zoos and aquariums are poised to play increasingly important roles in mitigating the global biodiversity crisis. However, the ultimate success of ex-situ conservation depends on animal welfare and effective husbandry and management practices. As such, an empirical understanding of ‘what...
