“…both in vitro and in vivo. The aqueous extraction method used by Oliveira et al (2010) reinforces this hypothesis because it required heating the samples at 60 ºC for one hour, which would denature most condensed tannins. Although we did not observe a decrease in FECs in either trial, a significant reduction in in vitro EHT was observed in the animals infected with T. colubriformis, demonstrating an inhibitory effect of the banana leaf on egg development.…”

“…The anthelmintic effect of the banana plant has been studied both in vitro and in vivo. Aqueous extracts from the leaves, false stems and flowering stalks of banana plants significantly reduced the in vitro recovery of Haemonchus larvae from pooled faeces from naturally infected sheep, with the average reduction in worm recovery ranging from 98.5 to 100% (Oliveira et al, 2010). Lambs that were artificially infected with H. contortus and fed with banana plant leaves for 21 consecutive days demonstrated significant FECs reduction compared with the control group, suggesting that the treatment reduced the fecundity of the worms (Marie-Magdalene et al, 2010).…”

Background: Helminths is a endoparasites that cause the major losses for profitable sheep production in Brazil. The increased development of resistant strains of endoparasites have enforced the search for sustainable alternatives. The aim of this paper was to provide information about endoparasites control with banana leaves in infected sheep as alternative control strategies and see its viability. Materials and Methods:In this study, we performed two trials to investigate the anthelmintic properties of banana leaves on endoparasites in sheep. In Trial 1, twelve sheep were artificially infected with Trichostrongylus colubriformis; in Trial 2, eleven sheep were artificially infected with Haemonchus contortus. Clinical examinations, packed cell volume, total protein, faecal egg counts (FECs) and egg hatchability tests (EHTs) were performed. At the end of the trials, the sheep were humanely slaughtered, and total worm counts were performed. Results: In Trial 1 and 2, no significant FEC decreases were note but significant diference in EHTs were observed. Total worm counts, clinical and haematological parameters did not reveal significant changes between the treatment and control groups. These results suggest that feeding dried ground banana plant leaves to sheep may reduce the viability of Trichostrongylus colubriformis eggs, and this anthelmintic activity is potentially exploitable as part of an integrated parasite management programme. Conclusion: However, further investigation is needed to establish the optimal dosage, develop a convenient delivery form and confirm the economic feasibility of using banana plantation byproducts as feed for ruminant species.

“…Em estudo conduzido por Macedo et al (2009), utilizando óleo essencial de Eucalyptus globulus na concentração de 43,5mg/mL, foi demonstrado 98,7% de inibição do desenvolvimento larval. Extrato aquoso de Musa sp., avaliado na concentração de 57,76mg/mL apresentou eficácia de 90% (Oliveira et al, 2010). Extratos de folhas e sementes produzidos com acetona, etilacetato e metanol produzidos com Annona squamosa, Eclipta prostrata, Solanum torvum, Terminalia chebula e Catharanthus roseus mostraram completa inibição (100%) quando utilizados na concentração de 50mg/mL (Kamaraj e Rahuman, 2011).…”

ResumoO objetivo deste trabalho foi determinar a eficácia in vitro do extrato etanólico de Aloe vera L. frente a estágios de vida livre de Haemonchus contortus. O fitoterápico foi produzido com percolação da polpa do vegetal com álcool absoluto, a 25ºC, sendo posteriormente liofilizado. Foram realizados o teste de eclodibilidade de ovos (TEO) e o teste de desenvolvimento larval (TDL), com concentrações crescentes (0,78 a 100mg/mL) em seis repetições. Para analisar a composição química do fitoterápico, procedeuse a marcha fitoquímica completa, analisando qualitativamente a presença de fenóis, taninos, antocianinas, antocianidinas, leucoantocianidinas, estero ides, triterpenos, saponinas, resinas e alcaloides; além da quantificação de fenóis totais, teste de toxicidade frente Artemia salina e ensaio antioxidante pelo teste de redução do radical DPPH. O produto obtido a partir de A. vera apresentou eficácia de 94,35 ± 1,13% no TEO, já no TDL a eficácia foi de 76,03 ± 0,45%, ambos na concentração de 100mg/mL. Nas análises fitoquímicas, foram encontrados diversos compostos que podem ter contribuído com o efeito anti-helmíntico, tanto direta como indiretamente. Os dados da marcha fitoquímica, aliados aos resultados dose-dependentes obtidos nos testes in vitro evidenciam que o extrato produzido possui potencial para combater H. contortus. Novos estudos devem ser realizados buscando maximizar a eficácia deste extrato, uma vez que foram encontrados resultados excelentes nos testes realizados.Palavras-chave: Etnoveterinária, fitoterapia, infecção parasitária. AbstractThe aim of this study was to determine the in vitro efficacy of ethanolic extract of Aloe vera L. against Haemonchus contortus free-living stages. The herbal material was produced by pulp leaving the solution with ethanol at 25°C and latter the material was lyophilized. After this, the product was used for the egg hatch test (EHT) and the larval development test (LDT) in different concentrations (0.78 to 100mg/mL) with six replicates. A complete phytochemical screening was performed to analyze the materials' chemistry composition, screening qualitatively the presence of phenols, tannins, anthocyanins, anthocyanidins, leucoanthocyanidins, steroids, triterpenes, saponins, resins and alkaloids; beyond the total phenols quantification, brine shrimp toxicity test and DPPH radical reduction antioxidant test. A. vera extract had an efficacy of 94,35 ± 1,13% using the EHT and of 76,03 ± 0,45% when using the LDT test, both in concentration 100mg/mL. Phytochemical tests showed few chemical compounds that could exert anthelmintic properties. The results obtained with the biochemical tests together with the dose-dependent effect found in in vitro tests demonstrate that extract has the potential to be a good drug candidate against H. contortus. Further studies should be conducted to maximize the effectiveness of the herbal, because it demonstrated excellent results in experiments.Keywords: Ethnoveterinary, herbal medicine, parasitic infection.

This study evaluated the effectiveness of pink pepper meal supplementation (PPM) in the dairy goats diet as an antiparasitic agent compared with ionophore, the monensin sodium. A total of 18 female Saanen goats, were distributed in a completely randomized in groups of three treatments and six replications, consisting of the experimental groups: negative control (did not receive anticoccidial agent or PPS), group 1 (supplemented with 30% of PPM) and group 2 (supplemented with anticoccidial agent -monensin sodium). There was a significant effect of treatments on voluntary feed intake on growing phases (P ≤ 0.05). Furthermore, the animals treated with PPM had the lowest food consumption compared with the other treatments (P ≤ 0.05), but without negative effect on live body weight. In general, at both phases of rearing, it was not detected significant difference between the voluntary feed intake of control group and with monensin sodium supplementation (P > 0.05), but the food consumption in the control group did not result on increase of live body weight probably due to sanitary challenges such as gastrointestinal parasites. The opposite was observed in animals treated with monensin sodium that had the highest body weight (P ≤ 0.05) that did not differ from animals fed with pink pepper (P > 0.05). By the way, in the growth phase our results revealed significantly effect of treatments on live body weight (P ≤ 0.05). Animals fed with pink pepper supplementation had a greater live body weight compared with the control (P ≤ 0.05) and similar to those supplemented with the monensin sodium (P > 0.05). The number of oocysts per gram of faeces was lower in animals treated with PPS that differed significantly from control (P ≤ 0.05). Regarding the count number of eggs per gram of faeces OPG, it was not detected significant effect of treatments (P> 0.05). It was found that the pink pepper supplementation was effective in the control of gastrointestinal parasites of goats, mainly on protozoa family Eimeriidae, revealing potential for use in alternative parasite control programs. Concomitantly also it was showed maximizing animal performance by high live body weight even with the reduction of voluntary feed intake.
