Utilization of enrichment objects by growing pigs in a commercial facility and the impact on behavior and skin lesions

Environmental enrichment is a way to provide growing pigs with a complex environment to explore and occupy themselves as they grow. Single point enrichment can provide some complexity to the environment while not having the drawbacks of substrate enrichment, including...

Social sham chewing in sows?

In this short communication, we describe chewing behaviour in sows with no apparent edible substrate in their mouth as a potential social behaviour. Chewing in sows during interaction with unfamiliar sows was unexpectedly observed in a study assessing social abilities...

The protective effect of social support: Can humans reassure pigs during stressful challenges through social learning?

Farm animals can socially learn to trust a human after observing that human handling a familiar conspecific gently, even if they never positively interacted with the human themselves. This study aimed to evaluate whether pigs are reassured by a human...

An effective environmental enrichment framework for the continual improvement of production animal welfare

Substrates and objects are provided to farm animals on the assumption that they improve animal welfare by enriching the environment, but these often fail to consider the extent to which an environmental enrichment (EE) improves animal welfare, if at all....

Comparison of low and high doses of pentobarbital or thiopental for euthanasia of isoflurane-anesthetized pigs

Barbiturate overdose is a common method for euthanizing pigs. However, barbiturates can cause tissue damage and may affect experimental results, so the minimal dose should be used. The minimal dose of barbiturate for euthanasia in pigs under isoflurane anesthesia has...

Non-surgical external jugular vein catheterization using an ear vein access in piglets

The objective of this study was to investigate the feasibility of external jugular vein catheterization through an ear vein in piglets. Forty-six sevoflurane-midazolam anaesthetized piglets were included. External jugular vein catheterization was conducted through the ear vein using the Seldinger...

Clean-catching urine from pigs: A method for collecting quality specimens for urinalysis and microbiological culturing in a laboratory environment

Urine is an important biological specimen for assessing various metabolic functions and drug clearance. In urinary tract infection research, urine is particularly important as urinary bacterial titres constitute the main diagnostic outcome for assessing the course of infection. Collecting uncontaminated...

Effects of repeated intramuscular injections on sow behaviour reactions and stress-related saliva biomarkers – A pilot study

Medicating large production animals, such as sows, individually can be challenging, especially when repeated treatments are needed. Intramuscular (i.m.) injections have been shown to be aversive, and an increased reaction could be expected over consecutive days of injections. The aim...

Environmental enrichment strategies for weaned pigs: Welfare and behavior

This research aims to evaluate the effects of different types and strategies of environmental enrichment for weaned pigs on behavior. Forty weaned piglets aged 21 to 28 days were distributed in a completely randomized design in five treatments: without enrichment...

Stress responses in pigs postweaning: Effect of heavier hybrid and weaning intact litters

Early and abrupt weaning of pigs is a stressful event. In addition, the use of hyperprolific sows with increasing numbers of live born piglets has decreased the average pig's birth weight, colostrum intake and weaning weight. The aim of this...
