[Gastrointestinal parasites in goat farms from Bergamo province (Lombardy, north Italy)].Parassitologia. 2006 Sep; 48(3):385-9.P
A survey on gastrointestinal parasites in goat farms in Bergamo province was carried out from May 2005 to January 2006. Thirty-one dairy goat farms and 836 adult female goats were examined. Faecal sampling was carried out before the antihelminthic treatments, and the sampling times were grouped in three seasonal periods (June-August, September-October and November-March). Faecal exams were carried out by a McMaster method and eggs per gram (EPG) were calculated for each gastrointestinal parasite. Differences in prevalence of Strongylida, Trichuris and Nematodirus were found between farms with goats on pasture and those where animals were permanently housed indoor. Strongyloides spp. showed higher values of prevalence in goats housed indoor. With regard to the sampling seasons, Strongylida eggs were more prevalent in summer while Nematodirus in winter in goats at pasture. Strongyloides occurred more frequently in autumn in stabled goats.
