How does supplementary feeding affect endoparasite infection in wild boar?

Abstract: Supplementary feeding is widely used in game management but may aid the transmission of parasites. Firstly, feeding sites attract animals and may be regarded as high-risk areas for parasite transmission. Secondly, high host population densities resulting from and supported by supplementary feeding, as well as accumulation of parasites in the environment, may increase parasite prevalence. Our aim was to investigate whether host density or the number of feeding sites drives endoparasite infection in an Estonian … Show more

“…Metastrongylids have been absent from Danish domestic pigs for decades [59,60], while historic data for wild boars is non-existent. Metastrongylids are widespread in European wild boars with prevalences of 28.8-60.0% [34,48,61], considerably lower than in our study (79.5%). One important exception though, is a prevalence of >80% reported in wild boars from the Estonian Island Saaremaa [45].…”

“…In large herbivore management, supplementary feeding is mainly intended to reduce herbivore impact on agriculture, to enhance body condition and reproductive performance, or to supply endangered animals with food or water in crucial periods of their annual life cycle (Kozak et al 1995;Loarie et al 2009). However, it is known that supplementary feeding may have negative long-term effects on wildlife populations (Murray et al 2016), including increasing parasite transmission in wild boar (Sus scrofa) (Oja et al 2017), European bison (Kołodziej-Sobocińska et al 2016a, d;Pyziel et al 2011;Radwan et al 2010), and other wild mammals (Sorensen et al 2014). Oja et al (2017) showed that the effects of supplementary feeding on gastrointestinal parasite infections in wild boar depend on the life cycle of the parasite species, as well as on environmental factors that affect survival and accumulation of oocysts and eggs at feeding sites.…”

An additional effect of supplementary feeding was increased density of wild boar, which promotes the transmission of parasites with a direct life cycle (Oja et al 2017).…”
