Determining whether a species' vocal communication system is graded or discrete requires definition of its vocal repertoire. In this context, research on domestic pig (Sus scrofa domesticus) vocalizations, for example, has led to significant advances in our understanding of communicative functions. Despite their close relation to domestic pigs, little is known about wild boar (Sus scrofa) vocal...

Porcine infectious anemia is a well-known disease that occurs worldwide and is caused by the uncultivable hemotrophic bacterium Mycoplasma suis. In this study the occurrence of M. suis in wild boars was investigated by employing a quantitative real-time LightCycler PCR. M. suis infections were detected in 36 out of 359 wild boars (10.03%). Sequencing of the 16S rRNA gene and subsequent phylogen...

BACKGROUND Since the re-appearance of wild boars in Sweden in the 1970s, the population has increased. Besides having large litter sizes, puberty at an early age is considered as an important factor contributing to the high reproductive potential of wild boar. Although controversial, supplemental feeding is applied to varying extent throughout the wild boar range in Sweden, and its effect on wi...

Wild pigs are the most prolific, very intelligent and secretive species that over the recent past has been in a lot of conflict terms with the humans. These animals are adaptive generalists and survive in wide range of habitats worldwide. The reproductive traits of wild pigs are extraordinary showing high prolificacy so it becomes impossible to control their population. These animals have adapt...

Linkage and QTL maps of Sus scrofa chromosome 17 (SSC17) were analysed with five markers and in three F2 families based on Wild Boar (W), Meishan (M) and Pietrain (P) crosses. The maps were similar across the three families and agree well with published maps. In the M · P family, new quantitative trait loci (QTLs) for growth and fat deposition were located in the vicinity of GHRH, whereas in th...

In order to obtain basic design criteria for anaerobic digesters of swine manure, the effects of different digesting temperatures, temperature shocks and feed loads, on the biogas yields and methane content were evaluated. The digester temperatures were set at 25, 30 and 35 degrees C, with four feed loads of 5%, 10%, 20% and 40% (feed volume/digester volume). At a temperature of 30 degrees C, t...
