摘要

The current study reports the parasitological results of a quality control audit in 21 European boar studs. Field investigations were performed over a 2-year period (2012-2013) during the winter and spring. From each stud, an average of 30 (range, 25-33) individual faecal samples and ejaculates from 615 randomly selected Pietrain boars were analysed. Statistical analysis revealed a significant effect (P 0.0001) of de worming regimen (DR) x age class of boar (A) and housing condition (H) x A on the presence of parasites. A second model indicated a significant effect (P = 0.0262) of DR x H x A on the presence of parasites. Sperm output was significantly affected (P 0.0001) by the DR. Based on this study, recommendations for de worming AI boars are proposed. (C) 2016 Elsevier Ltd. All rights reserved.
