Update on current hormonal and non-hormonal contraceptive options in non-human primates

Reproductive success in captive non-human primates (NHPs) has increased the demand for safe, effective, and reversible population control methods. This review provides an overview of the current literature on hormonal and non-hormonal contraceptives as reproductive control methods in NHPs. Where...

The effect of rearing and adult environment on HPA axis responsivity and plumage condition in laying hens

The hypothalamic–pituitary–adrenal (HPA) axis responsivity is influenced by early life experience and also modified by the environment an individual experiences as an adult. Because laying hens are transferred from rearing to laying farms at 16–18 weeks of age, they are...

Impact of musical rhythm on blood, physiological and welfare parameters in stabled horses

The aim of this study was to evaluate the effects of two styles of classical music, based on different tempos (BPM), on the physiological and blood parameters of horses during social isolation and restriction of movements. First experiment was carried...

Life beyond a jar: Effects of tank size and furnishings on the behaviour and welfare of Siamese fighting fish (Betta splendens)

Globally, Siamese fighting fish (Betta splendens) continue to be sold and kept in small, barren jars or tanks, with little concern for their welfare. This study aimed to examine the impact of housing size and furnishings (i.e. live plants, refuges)...

Standard methods for marking caudate amphibians do not impair animal welfare over the short term: An experimental approach

Major advancements in ecology and biodiversity conservation have been made thanks to methods for marking and individually tracking animals. Marking animals is both widely used and controversial due to the potential consequences for animal welfare, which are often incompletely evaluated...

Environmental enrichment affects immunity and reduces disease severity in pigs after co-infection, with stronger effects when applied from birth than from weaning

We investigated whether environmental enrichment applied at different life stages of pigs affects the susceptibility to and severity of disease by studying immune cell functions around weaning and during nursery, the effects of infection in ex vivo models and in...

Report of the 2023 RSPCA/UFAW/IAT Rodent Welfare Group Meeting

This report summarises the meeting and covers discussions ranging from housing and husbandry to refinement in procedures, education, and learning from companion rate care. It includes some action points for readers to consider raising at their own establishments.

The 3Hs Initiative—Housing, handling, and habituation

We have looked at our housing, handling and habituation approaches to identify areas to make improvements. This is critical for our resaerch outputs and has the benefit of reducing the cumulative suffering the animals experience by reducing stress and negative...

Use of the oxygen reserve index/FiO2 as a non-invasive index to estimate venous admixture in anesthetized dogs

The oxygen reserve index (ORi) is a novel, non-invasive parameter that estimates arterial oxygen partial pressure (PaO2) during hyperoxia when the fraction of inspired oxygen (FiO2) is elevated. This study aimed to assess the utility of the ORi/FiO2 ratio as...

The effect of preference assessment-informed enrichment device colour on biting and foraging behaviour in loggerhead sea turtles

Although environmental enrichment procedures have demonstrated their benefit to non-human animals in zoos and aquariums, the field has given little attention to phylogenetic variables that might affect their efficacy. Recently, research with loggerhead sea turtles Caretta caretta has demonstrated that...
