Eficácia de resíduos da bananicultura sobre a inibição do desenvolvimento larval em Haemonchus spp. provenientes de ovinos

Abstract

This study evaluated the in vitro efficacy of aqueous extracts from banana crop residues on the inhibition of larval development of sheep gastrointestinal nematodes. The quantitative and qualitative coproculture technique was performed to evaluate the anthelmintic efficacy of the aqueous extract of leafs, pseudostems and hearts from banana plants, cv 'Prata Anã', at 25, 75 and 150mg mL-1 concentrations, in a completely randomized design. The results showed that the three extracts, in concentrations equal to or greater than 75mg mL-1, decreased significantly (P<0.05) the nematodes larval development, with efficacy up 96.9%. The identification of the developed larvae revealed occurrence of Haemonchus spp. In the evaluated samples, allowing to conclude that the tested parts of this plant showed anthelmintic properties on the larval development of this important parasite.
