Grief-like distress responses in horses after the death of a conspecific

As a social species, it would be anticipated that horses may display altered behaviours toward dying or dead conspecifics. However, there is remarkably little literature on this subject. The aim of this study was to identify behavioural changes in horses...

Novel application of machine learning to enhance untrained and inexperienced evaluators’ diagnosis of acute pain in pigs

Accurately identifying pain is a critical first step required to adequately mitigate pain and improve pig health, welfare and quality of life. The objective of this study was to verify whether random forest and support vector machine algorithms trained utilizing...

Refining in-cage enrichment for specialized mouse scenarios

Environmental enrichment is a critical component of a high-quality animal care and use program to provide opportunities for species-specific behaviors and redirect abnormal repetitive behaviors. We used a scoring system to review our enrichment for singly housed mice to assess...

Five-domain-based evaluation of environmental enrichment in Japanese macaques (Macaca fuscata) to reduce aggressive behavior

Compared with wild troops, Japanese macaques (Macaca fuscata), which are commonly housed in cage-like enclosures in zoos and laboratories, face limited feeding opportunities, leading to intense competition and frequent aggression. Such aggression often results in injuries, highlighting the need for...

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...

Social dynamics and behavior of zoo-housed red-footed tortoises at different housing densities

Within zoos, it is common for animals that are considered solitary to be housed with conspecifics. This may be due to a variety of factors such as spatial constraints within zoos, difficulties associated with transferring animals, breeding goals, and/or other...

Advancing canine welfare assessment in kennels: Evaluating the validity of Field Instantaneous Dog Observation (FIDO) scoring in commercial breeding kennels

Accurate assessment of social fear in dogs housed in commercial breeding kennels is necessary to inform their behavioral management, including interventions needed to support their welfare. The Field Instantaneous Dog Observation (FIDO) tool, which was developed to quickly identify areas...
