Avaliação da eficácia de Typha domingensis Pers (Taboa) e Operculina hamiltonii (G. Don) D.F. Austin & Staples (batata de purga), in natura sobre nematóides gastrintestinais de caprinos, naturalmente infectados, em clima semi-árido.

Abstract

One of the main problems of the goat’s herd are the worms, however, the search for alternative controls have been increased, particularly the phytotherapie. This study aimed to evaluate the efficacy of Typha domingensis Pers and Operculina hamiltonii, in natura, on gastrointestinal helminthes infections in naturally infected goats in semi-arid region. Thrirty goats were used and T. domingensis of the rhizome and root of O. hamiltonii, with completion of phytochemical. Feces were collected on days zero, seven and 25 to achieve the FECs; and blood samples were collected at seven, 14 and 28 days of treatment for erytrogram and biochemical dosages. The animals were divided into five treatments with six repetitions. The treated groups showed a reduction in the average number of FEC at seven and 25 days when compared with the control on the same period, the highest percentages of effectiveness of O. hamiltonii were of about 84% and 70% in seven and 25 days post treatment, respectively. The values of MGV, Erythrocytes, Hematocrit and Hemoglobin were within the normal range for goats. Treatments affected values of MGV and MGHC, and concerning to Erythrocytes, Hematocrit and Hemoglobin, there was interaction among periods of sampling. The mean values of Total Protein, Albumin, AST and ALT were below the normal ranges. Treatments did not affect serum values of total protein, AST and ALT. Providing T. domingensis Pers and O. hamiltonii did not affect the physiorganic response of animals. O. hamiltonii was effective in controlling gastrointestinal nematodes of goats in semi-arid region.
