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...

Effects of microclimate during transport on physiological indicators of market pig welfare: A systematic review with meta-analysis

During transportation, microclimatic conditions can fluctuate significantly, affecting pigs’ thermal comfort and leading to compromised welfare and production losses. Although numerous studies have examined the effects of heat stress during transport on pig welfare and meat quality, it remains unclear...

A study on light preference in gilts via behavioral pattern analysis

The rational design of artificial lighting systems in pig housing can enhance animal welfare, thereby boosting gilt health and reproductive performance while improving economic metrics for swine farms. To identify the optimal light environments for gilts under artificial illumination, we...

Behavioral Biology of Laboratory Animals

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Regular play opportunities during the grow-finish phase improve pig trainability and learning in a cognitive bias test

Promoting play behaviour could enhance pig welfare in intensive production systems. Play is associated with positive emotions, and regular play opportunities may positively alter pigs’ affective states. The affective state of pigs can be indirectly assessed through a behavioural test...

Biopolymer-based nesting material for sows and its consequence on nest-building behavior, farrowing kinetics and piglet vitality

In the present study, we evaluated the effects of a soluble and biodegradable biopolymer-based material, structurally resembling natural fiber, as an alternative nesting-material for prepartum gilts. A total of 18 first parity sows and their litters were studied. One hour...

A single-dose pharmacokinetic study of metronidazole administered to Gottingen minipigs (Sus scrofa) by oral gavage or voluntary oral dosing

Oral gavage (OG) dosing can be stressful to pigs and is associated with the risk of complications. To evaluate a potential refinement, we compared the pharmacokinetics of a drug with a known aversive taste (metronidazole) administered orally to 6 Gottingen...
