Copalic (CA) and kaurenoic (KA) acids are the main diterpenes found in the oleoresin extracted from the copaiba tree (Copaifera sp). This study aimed to characterize the metabolism of CA and KA in rat and human liver microsomes using liquid chromatography with tandem mass spectrometry (LC-MS/MS). The in vitro assays showed deviations from the Michaelian kinetics in the metabolism of CA and KA. Putative metabolites of CA and KA were characterized by LC-MS/MS using electrospray ionization (ESI) with time of flight (LC-ESI-TOF) and ion-trap (LC-ESI-IT) systems and identified as a CA isomer and 16,17-dihydroxy-kaurenoic acid, respectively. CA and KA are subject to extensive metabolism with each passage through the liver with extraction ratios (E) estimated as 0.97 and 0.99, respectively. In conclusion, the kinetic parameters and metabolites described here might support drug development and the traditional use.

Copaiba oil has been used for more than 390 years, however, considering the time of empirical use, there are a scarce number of publications on its activities. This essential oil is a phytomedicine proven to be efficient against some microorganisms. However, different from other phytomedicines which are well established, antimicrobial studies on copaiba oil can present some bias due to the lack of standardization. This review; summarizes recent works, from 2009 to 2016, into the antibacterial and antifungal activities of copaiba oil; discusses issues affecting studies on this oil; and calls for more in vitro and clinical studies.

The present study evaluated the effect of the incorporation of copaiba oil, in direct and in microencapsulated form, into films based on Xanthosoma mafaffa Schott starch. Initially, the characterization of copaiba oil by gas chromatograph coupled with mass spectrometry (GC-MS) and its antimicrobial activity against gram-positive and gram-negative bacteria was performed. The films were produced by the casting technique and characterized in relation to physical, chemical, structural, and antimicrobial activity. Sesquiterpenes, mainly &beta, caryophyllene, were the predominant compounds in copaiba oil, showing antimicrobial activity against B. subtilis and S. aureus. The films showed forming capacity, however, was observed a decrease in solubility and revealed an increase in hydrophobic characteristics. However, the oil reduced the tensile strength and elongation, while the microcapsules did not influence the mechanical properties in comparison to the control film. From microstructure analysis, changes in the films roughness and surface were observed after the addition of oil both directly and in microencapsulated form. Films incorporated with microparticles were able to inhibit the gram-positive bacteria tested, forming inhibition zones, indicating that the encapsulation of copaiba oil was more efficient for protecting bioactive compounds from the oil, suggesting the possible application of mangarito starch-based films incorporated with copaiba oil as biodegradable packaging.

The present study aimed at evaluating the effects of a coating based on copaiba oil on the quality of eggs stored for different periods. Eggs were coated with copaiba oil solutions (4, 8, 12, 16, or 20% copaiba oil) or not (control) and stored for 1, 7, 14, 21, 28 or 35 days at room temperature. The following parameters were evaluated: egg weight loss, egg components (albumen, yolk, and eggshell) relative weights, egg specific gravity, Haugh units, eggshell quality, and sensorial attributes. Eggs stored for 35 days presented the highest weight losses. Coating (20% copaiba oil solution) reduced egg weight loss up to 41.02%. Coated eggs presented better internal quality (yolk and albumen heights, specific gravity, and eggshell strength). Sensorial attributes were negatively affected by storage time (aroma and flavor), and copaiba oil solution (aroma, appearance, and flavor), with the natural odor of copaiba described by the tasters. Egg internal, external, and sensorial quality worsened with storage time. Solutions containing 16 and 20% copaiba oil can be used as a biofilm to coat eggs, preserving its internal and external quality, and may affect their sensory characteristics, and therefore, may be a viable alternative for maintaining the internal quality of eggs stored at room temperature for long periods.

E eucalipto (Eucalyptus sp.) sobre o crescimento micelial de Alternaria alternata e Colletotrichum musae. O trabalho foi realizado no Centro de Ciência e Tecnologia Agroalimentar da Universidade Federal de Campina Grande, Pombal, Brasil, no peíodo de julho a agosto de 2018. Os experimentos foram conduzidos em delineamentos inteiramente casualizados com sete tratamentos e cinco repetições. Os óleos essenciais foram incorporados ao meio de cultura PDA (Potato-Dextrose-Agar) e vertidos em placas de Petri. Os tratamentos consistiram de quatro concentrações de óleo (0,4, 0,6, 0,8 e 1,0%), um controle negativo (0,0%) e dois controles positivos (os fungicidas Thiram e Mancozebe). Os fungos foram inoculados em placas e incubados por sete dias a 27 ± 2 ° C. O diâmetro das colônias foi medido a cada dia e utilizado para calcular a porcentagem de inibição do crescimento micelial (PIC) e índice de velocidade de crescimento micelial (IVCM). Os óleos de copaíba e eucalipto reduziram o crescimento micelial de A. alternata e C. musae em todas as concentrações. O óleo de copaíba apresentou inibição moderada, com percentuais médios variando de 26,6 a 33,68% para A. alternata e de 39,5 a 49,6% para C. musae. O óleo de eucalipto apresentou alta inibição, com médias variando de 30,0 a 79,7% para A. alternata e 35,6 para 66,3% para C. musae. As concentrações 0,8 e 1,0% apresentaram os maiores valores de inibição em ambos os óleos, porém essas inibições foram menores que as causadas pelos fungicidas. O óleo de eucalipto na concentração 1,31% poderia inibir totalmente A. alternata, mas em todos os outros casos, os óleos seriam incapazes de causar inibição total. Óleos de copaíba e eucalipto inibem o crescimento micelial de A. alternata e C. musae em condições in vitro. As concentrações de 0,8 e 1,0% proporcionaram o maior efeito inibitório. This study evaluates the in vitro fungitoxic effect of copaiba (Copaifera sp.) and eucalyptus (Eucalyptus sp.) essential oils on the mycelial growth of Alternaria alternata and Colletotrichum musae. The work was carried out at the Center for Agrifood Science and Technology of the Federal University of Campina Grande, Pombal, Brazil, from July to August 2018. The experiments comprised completely randomized designs with seven treatments and five replicates. Essential oils were incorporated into PDA culture medium (Potato-Dextrose-Agar) and poured into Petri dishes. The treatments consisted of four oil concentrations (0.4, 0.6, 0.8, and 1.0%), a negative control (0.0%) and two positive controls (the fungicides Thiram and Mancozeb). The fungi were inoculated on plates and incubated for seven days at 27±2°C. The diameter of the colonies was measured every day and use to calculate the percentage of mycelial growth inhibition (PGI) and index of mycelial growth speed (IMGS). Copaiba and eucalyptus oils reduced the mycelial growth of A. alternata and C. musae in all concentrations. The copaiba oil showed a moderate inhibition, with mean percentages ranging from 26.6 to 33.68% for A. alternata and 39.5 to 49.6% for C. musae. The eucalyptus oil showed high inhibition, with means ranging from 30.0 to 79.7% for A. alternata and 35.6 to 66.3% for C. musae. The concentrations 0.8 and 1.0% had the highest inhibition values in both oils, but these inhibitions were lower than the ones caused by the fungicides. The eucalyptus oil at 1.31% could totally inhibit A. alternata, but in all other cases, the oils were unable to cause total inhibition. Copaiba and eucalyptus oils inhibit the mycelial growth of A. alternata and C. musae under in vitro conditions. Concentrations of 0.8 and 1.0% provided the highest inhibitory effect.

The potential insecticidal of oils from southwestern Amazon plants against Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) was investigated. Initial bioassays were performed with undiluted oils from 11 plant species. The efficacy of the oils was evaluated against eggs and third -instar caterpillars of S. frugiperda. The oils of Copaifera sp. (Leguminosae), Orbignya phalerata (Arecaceae), and Carapa guianensis (Meliaceae) displayed a high efficacy against the caterpillars and were used in subsequent concentration-response bioassays, at concentrations established through preliminary tests. The highest nonlethal concentrations of oils and the lowest lethal concentrations were calculated. A completely randomized design was adopted in both bioassays. The LC50 of the oils varied from 7.50 to 60.84% (v/v). Copaifera sp. oil had the highest toxicity and was 6.84-fold more toxic than O. phalerata oil and 8.11-fold more toxic than Carapa guianensis oil. In general, oils from Copaifera sp., O. phalerata, and Carapa guianensis were effective in controlling S. frugiperda caterpillars under laboratory conditions, and are good candidates for use in integrated management programs of corn pests. RESUMO Investigou-se o potencial inseticida de óleos vegetais de plantas ocorrentes na Amazônia Sul Ocidental sobre Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae). Inicialmente, foram realizados bioensaios utilizando-se óleos puros (sem diluições), oriundos de 11 espécies vegetais. A eficiência dos óleos foi avaliada para ovos e para lagartas de terceiro ínstar de S. frugiperda. Os óleos de Copaifera sp. (Leguminosae), Orbignya phalerata (Arecaceae) e Carapa guianensis (Meliaceae) apresentaram elevada eficiência para as lagartas de S. frugiperda, sendo, portanto utilizados nos bioensaios subsequentes de concentração-resposta. As concentrações de cada óleo, utilizadas nestes testes de concentração-mortalidade, foram estabelecidas por meio de testes preliminares. Estabeleceram-se as maiores concentrações dos óleos em que não ocorresse morte de insetos e as menores concentrações em que ocorresse a maior mortalidade. Com base nos dados obtidos, foram estabelecidos os intervalos definitivos. O delineamento inteiramente casualizado foi adotado em ambos os bioensaios. As CL50 variaram de 7,50 a 60,84% (v/v) entre os óleos. O óleo de Copaifera sp. apresentou maior toxicidade para as lagartas, sendo 6,84 vezes mais tóxico que o óleo de O. phalerata e 8,11 vezes mais tóxico que o óleo de Carapa guianensis. Em geral, os óleos de Copaifera sp., O. phalerata e Carapa guianensis são eficazes no controle de lagartas de S. frugiperda, sob condições de laboratório, destacando-se como candidatos a uso nos programas de manejo integrado das pragas do milho.

In vitro bioassay using Sarcoptes scabiei as a test microorganism is a viable method of study for diverse drugs with acaricidal properties. A great amount of assays proves the diverse and efficient biological activity of extracts and compounds from Brazilian savanna plants. This study had as main object, test and compare the acaricidal activity of four Brazilian Cerrado bioproducts: Stryphnodendron adstringens Mart., Copaifera sp., Lafoensia pacari A. St Hil. and Pterodon emarginatus Vogel, 1837. To perform this test S. scabiei mites were collected from crusts removed on ears of highly infected sows. The mites were selected and separated in Petri dishes with three different concentrations (25, 50 and 75%) of each bioproduct, to evaluate their potential acaricidal activity. The mortality of the mites was counted in each Petri dish every hour, during five hours. The statistical analyses demonstrated differences between the bioproducts tested. The oleoresin of Copaifera sp. and P. emarginatus presented the best results with 100% of mites mortality after treatment. The ethanolic extracts of S. adstringens and L. pacari demonstrated lower acaricidal activity when compared to the oleoresins, with little or no difference among the control groups tested. This bioassay demonstrated to be efficient, reliable, low cost and easy accomplishment. Oil resins from Copaifera sp. and P. emarginatus have in vitro acaricidal activity against adult females of S. scabiei var. suis. RESUMO : O uso de Sarcoptes scabiei como microrganismo teste para bioensaio in vitro é um método de estudo viável para diversas drogas acaricidas. Muitos ensaios comprovam a diversidade e eficiência de atividade biocida de extratos e componentes presentes em plantas do cerrado brasileiro. Este trabalho objetivou testar e comparar a atividade acaricida de quatro bioprodutos do cerrado brasileiro: Stryphnodendron adstringens Mart., Lafoensia pacari A. St Hil., Copaifera sp. e Pterodon emarginatus Vogel, 1837. Para este estudo, ácaros S. scabiei foram colhidos em crostas removidas de orelhas de fêmeas suínas altamente infestadas. Os ácaros foram selecionados, separados e colocados em placas de Petri com três diferentes concentrações (25, 50 e 75%) de bioprodutos, para avaliar o potencial de atividade acaricida de cada um. Foi realizada a contagem da mortalidade dos ácaros em cada placa de Petri a cada hora, durante cinco horas. As análises estatísticas demonstraram diferenças entre os bioprodutos testados. As óleo-resinas de Copaifera sp. e P. emarginatus apresentaram os melhores resultados, com 100% de mortalidade dos ácaros após tratamento. Os extratos etanólicos de S. adstringens Mart. e L. pacari demonstraram menor atividade acaricida quando comparados as óleo-resinas, com pequena ou nenhuma diferença entre os resultados dos grupos controle. Este ensaio demonstrou ser uma ferramenta eficiente, confiável, de baixo custo e de fácil realização. As óleo-resinas Copaifera sp. e P. emarginatus possuem atividade acaricida in vitro sobre fêmeas adultas de S. scabiei var. suis.

Goid é o agente etiológico de uma das principais doenças na cultura do feijão-caupi, vulgarmente conhecida como podridão cinzenta do caule. Em decorrência da falta de produtos fitossanitários registrados para o controle desta doença um aumento na busca por métodos de controle alternativo é cada vez mais comum. O objetivo do presente trabalho foi avaliar o efeito de óleos essenciais sobre o crescimento micelial do fungo M. phaseolina. Os óleos testados foram de hortelã (Mentha sp.), eucalipto (Eucalyptus spp.), copaíba ( Copaifera sp.) e alecrim-da-chapada (Lippia gracilis), nas concentrações 0,4; 0,6; 0,8 e 1,0%. Os óleos foram incorporados ao meio de cultura do tipo BDA e posteriormente vertidos em placas de Petri de 90x15mm, após a solidificação do meio, discos de 8mm contendo o micélio do patógeno foram repicados para as placas com os respectivos tratamentos. O experimento foi conduzido no delineamento experimental inteiramente casualizado (DIC) em arranjo fatorial 4 x 4 + 1 +1, sendo dezesseis tratamentos mais uma testemunha negativa e uma testemunha positiva que constou da aplicação suplementar no meio (BDA) do fungicida Sportak 450 EC (Procloraz), e cinco repetições, totalizando 90 parcelas experimentais. Posteriormente todas as placas foram transferidas para incubadora do tipo B.O.D. (biochemical oxygen demand) a 27 ± 2 ºC. Foram realizadas medições diárias do diâmetro da colônia em dois sentidos perpendiculares até que tomasse toda a superfície do meio de cultura de uma das placas. Os dados obtidos foram interpretados por meio de análise de variância não paramétrica e as médias foram comparadas pelo teste de Kruskal-wallis, a 5% de probabilidade de erro e Scott Knott a 5% de probabilidade nos casos em que existiram diferenças significativas e normalidade dos dados. Os óleos essenciais de hortelã e alecrimda-chapada apresentaram melhores resultados quanto a inibição do crescimento micelial, enquanto que os óleos de eucalipto e copaíba apesar de potencialmente promissores, apresentaram inibição intermediária do crescimento micelial do fungo. Macrophomina phaseolina (Tassi.). Goid is the etiological agent of one of the major diseases in cowpea bean crop, commonly known as gray rot stem. Due to the lack of registered phytosanitary products to control this disease, the search for alternative control methods is increasingly common. The objective of this study was to evaluate the effect of essential oils on the mycelial growth of M. phaseolina. The oils tested were Mentha sp.,Eucalyptus spp., Copaifera sp., and Lippia gracilis at concentrations of 0.4; 0.6; 0.8 and 1.0%. The work was conducted in Phytopathology Laboratory of the Federal University of Campina Grande. Daily measurements of the colony diameter were performed in two perpendicular directions until it filled the entire surface of the culture medium of one of the plates. The experiment was conducted in a completely randomized experimental design in a factorial arrangement 4 x 4 + 1+1, with sixteen treatments plus one negative control and one positive control, which consisted of the supplemental application in the medium (BDA) of the fungicide Sportak 450 EC (Procloraz), and five replications, totaling 90 experimental plots. The data were interpreted through non-parametric analysis of variance and the means were compared by the Kruskal-wallis test, with a 5% probability of error and Scott Knott at 5% probability in cases where there were significant differences and data normality. The Mentha sp. essential oil and Lippia gracilis showed better results in inhibiting mycelial growth, while the Eucalyptus essential oil and Copaifera, although potentially promising, showed intermediate inhibition of fungal mycelial growth.

O objetivo deste trabalho foi avaliar a aplicação de óleo essencial de copaíba no controle da antracnose, nos frutos do maracujazeiro-amarelo, e comparar sua ação fungicida/fungistática in vitro com o óleo resina de copaíba. No experimento in vivo, os frutos foram inoculados com uma suspensão de esporos da ordem de 10(6) conídios mL-1 e 1% de Tween 80, acondicionados em bandejas de polipropileno e colocados em câmara incubadora com temperatura de 25ºC e 90% de umidade relativa do ar. Passadas 24 horas da inoculação, pulverizou-se óleo essencial nas seguintes concentrações: T1= 0 mL L-1; T2= 0,25 mL L-1; T3= 0,5 mL L-1; T4= 0,75 mL L-1; T5= 1,0 mL L-1, sendo avaliados a perda de massa do fruto, a severidade da antracnose e o número de lesões, ambas aos seis dias. Para o experimento in vitro, utilizou-se do meio de cultura batata-dextrose-ágar (BDA) que, após ser esterilizado em autoclave (120 ºC), recebeu óleo essencial e óleo resina de copaíba (0; 0,5; 1,0; 1,5 e 2,0 mL L-1). Após o resfriamento do meio de cultura, foi repicado para o centro da placa um disco de micélio de 12,5 mm de diâmetro de Colletotrichum gloeosporioides; e as placas, incubadas a 25ºC e 90% de umidade. A aferição do crescimento micelial foi verificada com o auxílio de paquímetro analógico, após sete dias de crescimento micelial. O óleo essencial de copaíba, nas concentrações de 0,25 mL L-1 a 1.0 mL L-1, não foi eficaz no controle pós-colheita do fungo da antracnose in vivo e na perda de massa dos frutos de maracujá. O óleo resina de copaíba inibiu o crescimento de C. gloeosporioides in vitro de forma mais eficiente que o óleo essencial de copaíba. The objective of this study was to evaluate application of the essential oil of copaiba in controlling anthracnose in fruits of passion fruit and compare their fungicidal/fungistatic action in vitro with copaiba oleoresin. In vivo experiment, fruits were inoculated with a spore suspension of 10(6) conidia mL-1 and 1% Tween 80, packed in polypropylene trays and placed in a dry incubator at temperature of 25 ºC and 90% of relative humidity. After 24 hours of inoculation, essential oil was sprayed at the following concentrations: T1 = 0 mL L-1, T2 = 0.25 mLL-1, T3 = 0.5 ml L-1, T4 = 0.75 mLL-1, T5 = 1.0 mLL-1, and evaluated the mass loss of the fruit, anthracnose severity and number of lesions, both at six days. For the in vitro study, we used culture media potato dextrose agar (PDA) which, after being sterilized by autoclaving (120 ºC), was added copaiba oleoresin and essential oil (0, 0.5, 1.0 , 1.5 and 2.0 mL L-1). After cooling the PDA culture media was peaked to the center of the plate a mycelial disc of 12.5 mm diameter of Colletotrichum gloeosporioides and the plates incubated at 25 ºC and 90% humidity. The measurement of mycelial growth was measured with the aid of analog caliper, after seven days of mycelial growth. The copaiba essential oil, in concentrations of 0.25 mL L-1 up to 1.0 mL L-1, was not effective in controlling post-harvest of the pathogen in vivo and in mass loss of passion fruits. The copaiba oils inhibited the growth of C. gloeosporioides in vitro more efficiently than the copaiba essential oil.

Este trabalho se propôs estudar as populações naturais de copaíba (Copaifera sp.) em Porto Trombetas-PA, para subsidiar o manejo sustentado e a exploração de óleo-resina pelos remanescentes de comunidades quilombolas no rio Trombetas. Foi feito o inventário florestal a 100% da área para descrever a estrutura populacional e a extração do óleo-resina a fim de quantificar o potencial produtivo na área de estudo e sua importância para as comunidades quilombolas da região. A área inventariada foi de 234,51 hectares (ha) com densidade de 38,15 indivíduos de copaíba por hectare, incluindo plântulas, regeneração natural e indivíduos adultos, sendo que na encosta a área inventariada foi de 99,88 ha com densidade de 41,16 indivíduos ha-1 e no vale a área foi de 134,63 ha com densidade de 35,91 indivíduos ha-1. O percentual de eficiência de estabelecimento dos indivíduos das categorias regeneração natural e indivíduos adultos possibilita a manutenção populacional na área de estudo. A densidade de indivíduos adultos (DAP ≥ 10 cm) foi de 0,49 ha-1 com padrão de distribuição espacial agregado, sendo que na encosta a densidade foi 0,55 ha-1 e no vale 0,45 ha-1. A densidade de indivíduos com potencial de produção de óleo-resina (DAP ≥ 30 cm) foi de 0,28 ha-1 com média de produção de óleo-resina de 0,714±0,218 litros e não apresentando diferença significativa para a produção de óleo-resina entre vale e encosta. A produção de óleo-resina foi obtida de 58% dos indivíduos com DAP ≥ 30 cm com média de 1,190±0,355 litros. Os resultados do “Diagnóstico Rural Participativo” mostraram que as atividades produtivas geradoras de renda mais importantes para as comunidades quilombolas do Rio Trombetas foram o extrativismo da copaíba seguido pela coleta de castanha (Bertholletia excelsa) e a feitura da farinha de mandioca (Manihot utilissima), apontando que suas diferentes fontes de renda e sustento são cumulativas e não excludentes. This work intended to study natural populations of copaíba (Copaifera sp.) in Porto Trombetas-PA, to the support sustainable management and the exploitation of oil-resin by the remnants of maroon communities from Trombetas river. The 100% forest inventory was made to describe population structure and the extraction of oleoresin in order to quantify potential production in the study area and its importance for the maroon communities. The inventoried area was 234.51 hectares (ha) with a density of 38.15 copaiba units per hectare, counting from seedlings to adults: in the slope a total area of 99.88 ha and a density of 41.16 ha-1 was inventoried and in the valley an area of 134.63 ha and a density of 35.91 ha-1 was inventoried. The efficiency percentage of establishment of individuals from natural regeneration categories to adults allows the population maintenance in the study area. The density of adults (DBH ≥ 10 cm) was 0.49 ha-1 with an aggregated spatial distribution pattern: in the slope the density was 0.55 ha-1 and in the valley it was 0.45 ha-1. The density of individuals with potential production of oleoresin (DBH ≥ 30 cm) was 0.28 ha-1 with an average production of oleoresin from 0.714 ± 0.218 liters and presenting no significant difference between valley and hillside oilresin production. The production of oilresin was obtained in 58% of DBH ≥ 30 cm individuals with an average of 1.190 ± 0.355 liters. Results of the "Participatory Rural Diagnostic" showed that most important productive activities income-generating for maroon communities from Trombetas river were the extraction of Copaiba followed by the collection of nuts (Bertholletia excelsa) and the manufacture of cassava flour (Manihot utilíssima), pointing to the cumulative and not exclusionary characteristic of their different incomes and livelihood.

Objetivou-se com este trabalho avaliar o efeito do óleo-resina da planta Copaifera sp. como aditivo fitogênico sobre os parâmetros de desempenho e como agente imunomodulador. Foram utilizados 500 pintos de corte machos Cobb500, distribuídos em delineamento inteiramente casualizado, em esquema fatorial 5x2, composto por 10 tratamentos e cinco repetições com 10 aves por unidade experimental. Os tratamentos foram divididos em animais desafiados e não desafiados para todos os tratamentos: grupo controle com e sem desafio, grupo com nível de inclusão de óleo-resina de 0.2% com e sem desafio, grupo com nível de inclusão de óleo-resina de copaíba 0.4% com e sem desafio, grupo com nível de inclusão de óleo-resina de copaíba 0.6% com e sem desafio, grupo com promotor de crescimento colistina com e sem desafio. O desafio microbiano foi fornecido as aves aos quatro dias de idade e aos 22 dias de idade contendo 4,5 x 109 UFC/mL. O peso final, ganho de peso, consumo de ração e conversão alimentar foram mensurados semanalmente até os 28 dias de idade das aves. Foi realizado a padronização de um teste de ELISA indireto para pesquisa de imunoglobulinas da classe IgA e avaliação da imunidade celular por meio de teste de reação a fitohemaglutinina e ao peso relativo dos órgãos linfóides. Os dados de desempenho foram analisados por meio do teste de ANOVA e Turkey a 5% de probabilidade. Para avaliação estatística para os dados imunológicos foi utilizado teste múltiplos nãoparamétrico de Kruskall-Wallis seguidos de teste T para comparação entre os diferentes grupos. Os resultados demonstraram que a inclusão de diferentes níveis de óleo-resina de copaíba na dieta de frangos de corte apresentaram efeito semelhante ao promotor de crescimento antibiótico e apresentou efeito aditivo nos níveis de anticorpos ao final do período experimental no nível de 0.2% de óleoresina. The aim of this work was to evaluate the effect of oil-resin from the plant Copaifera sp. as phytogenic additive on broiler performance and as immunomodulatory agent. Five hundred broiler chicks were used (Cobb500 males), distributed in a randomized design experiment in factorial 5 x 2, composed of 10 treatments and five replications with 10 birds per pen. The treatments were divided in animals challenged and not challenged for all treatments: control group with and without challenge, oil-resin from copaiba 0.2%, group oilresin from copaiba 0.4%, group of oil-resin from copaiba 0.6 and group with growth promoter colistin. The challenge with pathogenic E. coli (4.5 x 109 UFCmL ) was realized at the age of four and 22 days old. The final weight, weight gain, feed intake and feed conversion were measured at weekly intervals until the age of 28 days. A in house indirect ELISA was standardized and immunoglobulin class IgA was evaluated. The cellular immunity was measured through skyn reaction test to phytohemagglutinin and analyzing the relative weight of the lymphoid organs. Performance data were analyzed through ANOVA and Turkey test with 5% of probability. For statistical evaluation of immunological data it was used multiple test non-parametric test, Kruskall-Wallis followed by T teste. The results showed that the inclusion of different levels of oil-resin from copaiba in broiler diet had similar performance when compared to the inclusion of antibiotic growth promoter. However it was observed an additive effect on antibody levels at the end of the trial period when oil-resin 0.2% was used. Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES
