Avaliação da resposta hematológica dos animais tratados com Typha domingensis Pers e Operculina hamiltonii sobre nematóides gastrintestinais de caprinos

Abstract

This study evaluated the hematological response of animals submitted to treatments with Typha domingensis Pers and Operculina hamiltonii, in natura, in the control of gastrointestinal helminthiasis in goats naturally infected. Thirty moxotó goats were used. The rhizome and root of T. domingensis and O. hamiltonii, were used in the phytochemistry analysis. The animals were divided into five treatments with the group I treated with moxidectin 0.2% in a single dose of 0.5 mg/kg, group II with T. domingensis using 10 g/20 Kg body weight, group III O. hamiltonii with a dosage of 09 g/20 Kg, group IV with T. domingensis (10 g/20 Kg) associated with O. hamiltonii (09 g/20 Kg) during three consecutive days and the group V as the control. Feces were collected on days zero, seven and 25 for the FECs and for the hematological tests blood was collected at seven, 14 and 28 days post-treatment, for the evaluation of hematocrit, hemoglobin, MGV and MGHC. The values of MGV, erythrocytes, hematocrit and hemogoblin were within the normality for goats. The treatments had no effect on MGV and MGHC. Regarding the erythrocytes, hematocrit and hemoglobin, there was an interaction among periods of sampling. Using this methodology, the supply of T. domingensis and O. hamiltonii had no affect on the hematology response of treated animals.
