Effects of light spectrum on pig behaviour, health and growth

Pigs show preferences to display certain behaviours under specific light spectra. Moreover, adding UVB light to the spectrum might enhance pigs’ vitamin D status. Despite the potential, there are still gaps in understanding the broader effects of light spectrum on...

Enriching the environment with multiple rooting materials and bedded rest areas improves welfare of finishing pigs

Providing environmental enrichment, including rooting materials and bedding, is essential for improving pig welfare by reducing tail, ear, and body lesions. In this observational field study of Norwegian commercial farms, all farms applied some level of environmental enrichment. Thus, rather...

Effects of dietary restriction on regulation of energy metabolism in male Wistar rats (Rattus norvegicus)

Laboratory rats are most often fed ad libitum (AL), but dietary restriction (DR) is commonly used to provide appropriate experimental designs. The current methods of DR have shortcomings; animals are often subjected to social isolation, periods of fasting, and disturbed...

Putting the evidence into evidence-based husbandry: A scoping review of empirical approaches to improving captive reptile welfare

Non-avian reptiles are commonly kept in captivity, including zoos, aquariums, farms, laboratories, classrooms, rehabilitation centres, and homes. With this wide range of captive conditions and potential diversity of species housed, it is crucial to ensure that these animals are housed...

Impacts of chopped food on primate behavior are not clear cut. A case study on zoo-housed ring-tailed lemurs

Measuring how food presentation influences behavior helps encourage practices that support natural foraging efforts for species housed in zoos. To test the effect of food presentation on a commonly housed zoo primate, observations of the behavior of ring-tailed lemurs (Lemur...

Relative preference for different pecking blocks offered as pairwise comparisons in White and Brown-feathered laying hens

Different commercially available pecking blocks (PBs) have varying nutrient composition, appearance, and texture. However, the relative preferences of laying hens for different PBs are unknown. We housed 120 Dekalb White and 120 Bovans Brown in twelve (360 cm x 116 cm x...

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,...
