Occurrence of parasitic diseases in sheep and goats in the District Federal, Brazil, during 2003 to 2009

Parasitism is a major factor limiting livestock production in general. The goat and sheep industry are affected by many parasites representing significant losses in meat, milk and wool culture. The recent introduction of sheep and goats in the Brazilian Midwest region brought with them new diseases not previously reported in the region. The aim of this study is to describe the occcurrence of major parasites, affecting sheep and goats in the Federal District and surrounding areas, and predisposing factors of these diseases to local herd reviewing cases obtained by necropsy of animals in the period 2003 to 2009. From October 2009 to July 2010 were reviewed the necropsy reports of the region in retrospect the years 2003 to 2009 looking for the demand for case studies of parasitic diseases. It was found to occcur of ectoparasitosis and endoparasitosis in small ruminants. The main parasites found were Haemonchus contortus and Oestrus ovis in both cultures, however Oesophagostomun sp. occcurred only in sheep. There was a higher occcurrence of Haemonchose in the rainy season in the Cerrado. This is the first epidemiological research of parasitism in goats and sheep in the region.
