Classificação de caprinos e ovinos com infecção natural por parasitos gastrointestinais por meio do método Famacha, proteinograma e exames coproparasitológicos

Abstract

The aim of this research was to identify the gastrointestinal parasites and evaluate the infection with strongyles in dairy goats and sheep in the Metropolitan Region of Recife - PE, through parasitologic fecal exams, Famacha tests and proteinogram. Animals were used from four farms, and two with concomitant goats breeding and sheep farm identified as 1 (G1) and farm 2 (G2), a only goats breeding (G3) and one only sheep breeding (G4).The research was conducted from September 2009 until July 2010. Flocks G1, G3 and G4 were studied for 10 months and Flock G2 for 8 months. The animals were examined by Famacha technique, packed cell volume and total protein plasma concentration. It was performed egg count (EPG), oocyst count (OoPG) and larvae count (LPG) per gram of feces, e animals were classified according a prior established convention to evaluating parameters values, using reference data for OPG, Hematocrit, and Famacha test to resistant, resilient and sick animals. Parasitism was observed in all study period in goats and sheep, identifying type Strongyloidea eggs, Strongyloides sp., Trichuris sp., Moniezia spp. and oocysts of Eimeria spp. The sheep had a better response to parasitism at studied region, ranking mostly of them as resistant and resilient, while most of the goats were framed as sick.
