Effect of cleaning /disinfection strategies on helminth infections in finishing pigs Organic Eprints
Vermeer, Herman M.; Borgsteede, Fred H.M.; Gaasenbeek, Cor P.H.; Blanken, Klaas.
Ascaris suum is the most prevalent helminth on organic pig farms (Carstensen et al., 2002) and is transmitted mainly via the faeces. The use of anthelmintics does not fit in the organic principles and preventive measures are promoted. This project focused on assessing the efficacy of a cleaning protocol for the dunging area of pens on Ascaris s. transmission to pigs. In 4 batches with 8 identical pens for 15 pigs each (n=480 pigs) 6 pigs per pen were orally infected with Ascaris s. The other pigs can be earliest infected at 10 weeks and half of the pens were thoroughly cleaned at that time. Affected livers and egg counts in the manure had to show if this cleaning protocol keeps the non infected animals free of Ascaris s. The results show no effect...

Effect of rooting area and drinker in the outdoor run on behaviour and Ascaris infection of organic pigs Organic Eprints
Vermeer, Herman M.; Borgsteede, Fred H.M.; Gaasenbeek, Cor P.A.; Altena, Henk.
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...

Extra snijmais goed voor welzijn varkens Organic Eprints
Bracke, Marc; Aarnink, Andrè; Vermeer, Herman M..
Vleesvarkens hebben graag een emmer snijmais. Dat blijkt uit praktijkonderzoek op Varkens Innovatie Centrum Sterksel, onderdeel van Wageningen UR. In vergelijking met stro heeft snijmais meer voederwaarde en het leidt minder snel tot verstoppingen in de mestput.

Farrowing accommodation for organic pigs Organic Eprints
Vermeer, Herman M.; Altena, Henk.
Newborn piglets in organic farrowing pens have a lower survival rate than in conventional farrowing pens. This difference is mainly caused by housing the sow loose compared to crated and by climatic effects of the outdoor temperature. Organic lactating sows should have at least 7.5 m² indoor area with straw and a 2.5 m² outdoor run. The aim of the project was to increase piglet survival in order to improve animal welfare as well as the profitability of organic farms. In the experiment we compared survival and behaviour in 3 pen types: type 1 with outdoor run, type 2 with an indoor run and a higher proportion of solid floor and type 3 without run. Data was analysed with Analysis of Variance using parity and liveborn piglets as covariables. Results of 131...

Studies on preventive strategies and alternative treatments against roundworm in organic pig production systems Organic Eprints
Borgsteede, Fred H.M.; Gaasenbeek, Cor P.A.; van Krimpen, M.M.; Maurer, Veronika; Mejer, Helena; Spoolder, H. A. M.; Thamsborg, S.M.; Vermeer, Herman M..
Organic and many ‘low input’ production standards for pigs require outdoor access, and as a consequence expose the animals to a wide range of potential endo- and ectoparasite infection sources. Conventional anthelmintics are used to control parasitic infections, but their preventive use is banned by the organic standards. The present paper investigates the potential of prevention of infection through better hygiene. Attempts were made to break the infection cycle through thorough pen cleaning 10 weeks after the pigs had been introduced to the pen. Although pen fouling can be reduced, the level of roundworm (Ascaris suum) infection was not reduced. Regular deworming with conventional medication is still required in addition to good hygiene.

The use of outdoor runs with rooting areas and drinkers by organic pigs Organic Eprints
