“…The highest concentration of this element was found in the spring and summer period and the lowest in the autumn. This phenomenon is probably due to seasonal variations in wild boar diets (Giménez-Anaya et al 2008;Baubet et al 2004). Baubet et al (2004) observed that green parts of plants are dominant in the diet of European wild boars in the spring.…”

The aim of this study was to determine liver and kidney concentrations of selenium in wild boars from the northwest part of Poland, depending on season of the year, age, sex, and body weight. Altogether, samples of livers and kidneys from 172 wild boars that were shot in 2005-2008 were investigated. Liver and kidney concentrations of selenium were determined using spectrofluorometric method. In all the animals studied, selenium concentration was several times lower in the liver than in the kidneys. Selenium concentration averaged 0.19 μg/g wet weight (w.w.) in the liver and 1.20 μg/g w.w. in kidneys. The present study showed that season (P≤0.05), age (P≤0.01), and body weight (P≤ 0.01) have a significant effect on selenium concentration in the liver of wild boars. Liver selenium concentration was the highest in spring (0.23 μg/g w.w.) and the lowest in autumn (0.16 μg/g w.w). Young animals (up to 1 year of age) and those with the lowest body weight (up to 20 kg) were characterized by a slightly lower selenium concentration in the liver compared to older and heavier animals. No significant differences were found in organ selenium concentration between males and females. According to biochemical criteria for the diagnosis of selenium deficiency in pig liver, which were used to evaluate selenium concentration in the liver of wild boars, no individuals were found to have optimal levels. Considering that in Se deficiency higher selenium concentrations are found in kidneys than in the liver, it can be presumed that the wild boars had Se deficiency. However, this is difficult to state conclusively because there are no reference values for this species.

“…native grasses intensively grazed by cattle, exotic pastures, grasslands with very small earthmounds and bare soil areas). The intensive use of grasslands and pastures had already been described in southern Pantanal and in other regions (Barrett 1982;Baubet et al 2004;Choquenot & Ruscoe 2003;Dexter 1998Dexter , 1999Graves 1984;Oliveira-Santos 2013), and plants like grass, herbs and forbs usually represent a considerable part of the feral pigs and wild boar diets (Baber & Coblentz 1986;Cuevas et al 2013a;Cuevas et al 2013b;Giménez-Anaya et al 2008;Hellgren 1993;Taylor & Hellgren 1997). Furthermore, the SDM approach showed that habitats with greater suitability for feral pigs are those predominantly herbaceous (around 80% coverage), interspersed with patches of seasonally dry forest (optimum between 35 and 40% coverage) and not too far from water bodies (around one kilometer).…”

This paper focus a rare case of natural disappearance of feral pigs (Sus scrofa) in an extensive area without using traditional methods of eradication programs. The study was conducted both in the Private Reserve of Natural Heritage (PRNH) Sesc Pantanal and in an adjacent traditional private cattle ranch. In 1998 feral pigs were abundant and widely distributed in the PRNH. However, the feral pigs were gradually disappeared from the area and currently the absence of pigs in the PRNH contrasts with the adjacent cattle ranch where the species is abundant. To understand the current distribution of feral pigs in the region we partitioned the effects of variation of feral pigs presence considering the habitat structure (local), landscape composition and the occurrence of potential predators.Additionally, we modeled the distributions of feral pigs in Northern Pantanal, projecting into the past using the classes of vegetation cover before the PRNH implementation (year 1988). Our results show areas with more suitability for feral pigs in region are a landscape dominated by pastures and permeated by patches of Seasonal Dry Forest. The species tends to avoid predominantly forested areas. Additionally, we recorded that the environmental suitability for feral pigs decreases exponentially as the distance from water bodies increases. The disappearance of feral pigs into PRNH area seems to be associated with changes in the landscape and vegetation structure after the removal of the cattle.

“…Agricultural plants are consumed in equal or higher proportion than non-agricultural plants, when available (Schley and Roper 2003;Herrero et al 2006;Giménez-Anaya et al 2008). Food preferences of wild pigs are reflective of the crops available to them (Schley and Roper 2003).…”

Attractants for wild pigs: current use, availability, needs, and future potential

et al. 2017

View full text Add to dashboard Cite

Populations of wild pigs (Sus scrofa) are burgeoning around the globe, and they are currently the target of extensive research and management efforts. Wild pigs are a highly successful invasive species that cause extensive damage to agriculture and native plant and animal communities. Lethal control is the most common management strategy used to reduce wild pig populations and their damage, and many lethal strategies rely on luring wild pigs to a specific location. Most commonly, a food commodity such as corn or maize (Zea mays) is used for attracting wild pigs to a site, but baiting with food is sometimes prohibited under wildlife laws, and visitation can be variable due to availability of alternative foods, level of harassment by humans, and acceptance of novel food source, devices, and activity. Wild pigs are highly adaptable with refined senses that enable them to interact with their environment and conspecifics in a complex manner. Wild and domestic pigs share keen senses, though differences exist due to suppressed stimuli, evolutionary gains and losses, or other factors related to needs for survival and fitness. Wild pigs routinely rely on acute olfaction to locate food, detect predators, and communicate with conspecifics. A pig's sense of taste is also considered to be refined and more acute than that of humans. An abundance of evaluations regarding various attractants for wild pigs has been conducted over the last several decades; yet, a scarcity of conclusive results on which attractants to use when and where still exists. As such, we undertook a comprehensive review of available information on potential attractants that could be used to aid management strategies of wild pigs such as hunting/shooting, trapping, pharmaceutical delivery, or density estimation. To complete this review, we assimilated and synthesized the most relevant literature, provide recommendations, and identify attractant evaluation needs for the enhancement of the global management of wild pigs.
