http://orgprints.org/13722/ Effect of rooting area and drinker in the outdoor run on behaviour and Ascaris infection of organic pigs Vermeer, Herman M. Borgsteede, Fred H.M. Gaasenbeek, Cor P.A. Altena, Henk Pigs Health and welfare Air and water emissions Hygiene is often a problem on the outdoor runs of growing organic pigs. Manure and urine are mainly excreted outside, but spread all over the run. Reduc-ing the dirty surface may improve well being, reduce ammonia emission, improve hygiene and reduce labour and parasite infections. The presence of a rooting area and of a drinker on the outdoor run were tested in a 2x2 factorial design. The pens with the rooting areas had a higher number of pigs on the outdoor run than the pens without a rooting area (1.6 vs 1.2 pigs). This was caused by more pigs in area 2 and 3. At higher temperatures there were more pigs outside, except in the root-ing area: this was popular at all temperatures. A rooting area resulted in a cleaner outdoor area, however in some cases the root-ing area became a dunging area. An extra outdoor drinker leads to a cleaner area around the drinker, but to a dirtier indoor area. No difference in Ascaris infection was found between the four treatment combinations. 2006-06 Report NonPeerReviewed application/pdf http://orgprints.org/13722/1/Vermeer_QLIF_4-1-1-3_RIAH_final_report_11-04-06.pdf Vermeer, Herman M.; Borgsteede, Fred H.M.; Gaasenbeek, Cor P.A. and Altena, Henk (2006) Effect of rooting area and drinker in the outdoor run on behaviour and Ascaris infection of organic pigs.
