Endoparasites in organic pig herds. [Endoparasitter i okologiske svinebesaetninger.]
DJF Rapport, Husdyrbrug. 2003 , ( No.49 ): 40 pp.
From March to October 1999 a study was made of parasites present in faeces and soil samples collected from 9 privately owned pig farms in Denmark which had been run on organic lines for a few months to 8 years; the size of the herds varied from 12 to 258 sows. the The endoparasites found were Ascaris suum in 28% of 12-week-old piglets, 33% of slaughter pigs and 4% of the sows; Trichuris suis in 4%, 13% and <1%, and Oesophagostomum spp. in 5%, 14% and 20%, respectively; no strongylid parasites were found. Very few Trichuris eggs were found in the soil, but they were present in 14% of the samples from areas used by the sows and 35% from areas used by the slaughter pigs. The first infective eggs were identified in July and the last in August. The numbers of Oesophagostomum larvae increased in pasture samples from May to October. 20 ref.
