Efeito do neem (Azadirachta Indica) no controle de nematódeos gastrintestinais em ovinos suplementados a pasto no período seco

Abstract: Efeito do neem (Azadirachta AbstractThe aim of this study was to evaluated the effect of Azadirachta indica (Neem) extracts upon the productive response and control of gastrointestinal nematodes in Santa Inês sheep during the dry season grazing. Twenty four sheep, were divided in three groups according to the following treatments: SPControl (Animals receiving protein supplement); SP-Oil (Animals receiving protein supplement and Neem oil extract) and SP -Leaf (Animals receiving protein supplement and Neem dry l… Show more

“…From day 28to 42, an effect of higher protein levels over EPG reduction was observed, indicating that the medium and high protein concentrations led to the reduction of nematodes in the gastro-intestinal tract of these animals. These findings are similar to the data obtained by Veloso et al (2004), who studied the effect of different protein levels on sheep, and Igarashi et al (2013), who studied the effect of protein supplement in association with neem oil and dry leaves (Azadirachta indica) on sheep. After day 49, an increase in the dietary protein levels did not affect EPG and resulted in a higher parasite load probably because the vermifuge was administered only at the beginning of the experiment.…”

“…Nos últimos anos o Neem vem recebendo atenção como uma alternativa fitoterápica, sendo também preconizado no controle de parasitas gastrointestinais de ovinos e caprinos (CHAGAS & VIEIRA, 2007;NOGUEIRA et al, 2005;UENO & FRAGA, 2006). Entretanto sua eficácia gera polêmica devido á resultados controversos, uma vez que os trabalhos, geralmente, realizados utilizando suas folhas (RAHMAN et al, 2009;CHAGAS et al, 2008;CHAGAS & Vieira, 2007), sementes ou óleo extraído de suas sementes (IGARASHI et al, 2013;NOGUEIRA et al, 2005) Em outro experimento Nogueira et al (2006), avaliando a eficácia das sementes de Neem desidratadas em caprinos na dosagem de 1,0g/kg e 3,0g/kg em três aplicações com intervalo de 13 dias, observaram um aumento no OPG dos animais tratados em quase todas as administrações, todavia, apesar da maior dosagem, não houve casos de intoxicação como relatado por Nogueira et al (2005). Resultados similares aos obtidos neste trabalho também foram relatados por Chagas & Vieira (2007) que ao avaliarem o efeito anti-helmíntico das folhas de Neem, em cabras, na dosagem de 30g/animal/dia durante cinco dias, observaram que o grupo controle ingeria todo alimento oferecido no cocho em menos de 30 minutos, enquanto que os animais que recebiam o Neem demoravam cerca de duas horas, demonstrando problemas de palatabilidade.…”

“…A prevalência do Haemonchus spp. seguida pelo gênero Trichostrongylus spp., nas coproculturas, foi semelhante a relatada por Chagas et al (2008); Pereira et al (2008); Vieira et al (2008); Moraes et al (2010) e Igarashi et al (2013). Não houve variação nas porcentagens de larvas de helmintos nas coproculturas, assim como também relatado por Chagas et al (2008).…”
