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...

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...

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...

How does the previous environment affect pigs’ responses when switching to a barren or enriched environment as assessed by Qualitative Behaviour Assessment?

Intensive pig farming systems are often characterised by barren and monotonous environments, which can impair pig welfare. While enriching the environment enhances pig welfare, less is known about the implications of changes in housing conditions regularly happening on commercial farms....

Tactile stimulation by humans: Do pigs prefer scratching or stroking?

Scratching and stroking are tactile interactions used to improve the animal-human relationship and reduce stress in pigs. Both interactions resemble behaviours from the behavioural repertoire of pigs and have been applied in previous studies. To investigate the relative efficacy of...

Effects of different ways of music stimulation on exploring, playing and aggressive behavior

In the breeding of farm animals, music serves as an environmental enrichment factor that can improve the mood and welfare level of animals. However, it is not clear whether pigs receiving different modes of musical stimulation can improve cognitive performance....

Voluntary additional welfare monitoring of farm animals used in research: Maximising benefits requires sustained support

The aim of this project was to co-create an animal welfare monitoring system that incorporated both positive and negative welfare measures that would contribute to best practice husbandry standards of farm animals in a real animal research setting. Researchers worked...

Clinical interpretation of body language and behavioral modifications to recognize pain in domestic mammals

Nonhuman animals use nonverbal cues to communicate their mental state about positive and negative events, including pain. Pain is a multidimensional process that elicits behavioral changes aimed at preventing further damage and promoting healing. These changes include restrictions on movement...

Review: Gut microbiota—a powerful tool for improving pig welfare by influencing behavior through the gut–brain axis

Animal welfare is one of the core concerns in the field of animal science, with behavior serving as a direct reflection of emotional state and health, and thus a key indicator for welfare assessment. With the widespread adoption of intensive...
