Summary: This study utilizes the IUCN Red List data to quantify the impacts of wild pigs on global biodiversity, showing that these animals threaten 672 taxa in 54 countries, with 14 species already extinct due to their impacts. The research highlights the pervasive threats posed by wild pigs across taxonomic groups, with island endemics and non-native range taxa being particularly vulnerable.

Summary: The study found that yawning contagion exists in domestic pigs, and pigs are more likely to yawn when perceiving others' yawns. Yawn contagion is influenced by individual kinship, gender, age, and proximity.

Summary: The study aimed to investigate the diet and stomach characteristics of feral piglets, and it found that feral piglets consume a variety of non-milk items, mainly consisting of vegetable material, from their first week in life onwards, which contributes to enhanced stomach development.

Summary: The study found that Panepinto micro pigs and Yorkshire pigs are able to acquire a joystick-operated video-game task, despite having some level of dexterity and visual constraints. Pigs needed to understand the task conceptually and demonstrate skilled motor performance during the training process.

Summary: Wild pigs are susceptible to low-dose warfarin, with generally low residues in postmortem tissues. However, further improvements to pig-specific bait delivery systems and bait palatability, as well as additional research on efficacy, cost, and non-target impacts, are needed before widespread implementation of warfarin-based baits.

Summary: The study found that lethal removal of wild pigs via trapping can significantly reduce pig density at some sites, with a qualitative reduction observed at other sites. There was little evidence of shifts in pig home-ranging behavior following removal, but a nuanced response in movement behavior was observed at a fine-scale level. This research provides insights into the impact of trapping on wild pig movement and its management implications, demonstrating how targeted trapping can temporarily alleviate the pressure on species sensitive to wild pig consumption.

Summary: Aujeszky's disease, caused by Suid Herpesvirus 1, was studied in wild boars in the Campania Region, with a seroprevalence of 23.85%. Gender was not associated with seropositivity, while age and location were significant factors. The study showed a constant circulation of the virus in the area.

Summary: By conducting eyeblink conditioning experiments on 3-week-old pigs, it has been demonstrated for the first time that young pigs have the potential to be a valuable behavioral tool in measuring neurodevelopment through cerebellar classical conditioning tasks.

Summary: The study found that anxiety behavior in pigs is mainly expressed through displacement activities in natural environments, and this behavior can be mitigated by social interactions. Pigs exhibit higher levels of anxiety behavior for a longer duration, and this behavior is primarily expressed by bystanders rather than opponents.

Summary: Rift valley fever (RVF), caused by the RVF virus (RVFV), primarily affects domestic ruminants and can also be transmitted to humans. This study confirmed that pigs can be experimentally infected with RVFV, although they may not show clinical symptoms. Pregnant sows can also abort following infection. The presence of viral RNA in swab samples suggests that pigs may shed RVFV for at least one month.

Summary: Young domestic piglets showed no clinical signs following RVFV infection, suggesting they may be subclinically infected with the virus.

Summary: Wild pigs are invasive species globally and have negative impacts on biodiversity and economies in their non-native habitats. Accurately predicting their body mass is important for eradication efforts. This study assessed the relationship between morphometric measurements and body mass of wild pigs, and developed equations to predict body mass using easily measured metrics. The equations were validated across different regions and could accurately infer wild pig body mass.

Summary: The study utilized a jet needle-free injection system to inject carbon nanoparticles into the skin of domestic pigs, assessing the morphological distribution of DMUs and observing ultrastructural changes. Results confirmed the role of DMUs as reservoirs of immune cells in the skin.

Summary: This study found that immunocastration has positive effects on the behavior and welfare of pigs, regardless of the housing environment. After the second vaccination, immunocastrates showed reduced sexual and fighting behavior, demonstrating the robustness of the positive effects of immunocastration.

Summary: This study evaluated the impact of environmental conditions and negative stimuli on the use of bait sites by wild pigs. The results showed that wild pigs exhibit increased use of bait sites during drier years and when not exposed to negative stimuli. It is recommended to intensify control efforts during drier periods and focus on eliminating potential surviving wild pigs that may have experienced negative stimuli.
