RESUMO O experimento foi realizado no setor de avicultura/UFRRJ, utilizando 348 galinhas semipesadas (linhagem Dekalb Brown), com 52 semanas de idade, criadas sob dois sistemas de produção: cage-free e em gaiolas. Os dados obtidos pela análise físico-química e microbiológica dos ovos e a resistência óssea à quebra foram submetidos à análise de variância. No caso de ocorrerem efeitos dos diferentes sistemas de produção, foi aplicado o teste de Tukey a 5% de probabilidade para comparação das médias. A qualidade físico-química foi igualmente favorecida pelos dois sistemas de produção, indicando que as circunstâncias experimentais propiciaram condições adequadas para a formação de ovos de boa qualidade. O sistema de gaiola não desfavoreceu as características ósseas das galinhas, apontando que, em densidades adequadas, a gaiola pode não exercer um fator prejudicial para a qualidade óssea. O sistema de produção cage-free piorou a contaminação da casca, comprovando que ovos postos em ninhos são mais contaminados em comparação aos produzidos em gaiolas.

ABSTRACT The experiment was carried out in the poultry sector / UFRRJ, using 348 semi-heavy hens (Dekalb Brown line), 52 weeks old, raised under two cage-free production systems and cages. The data obtained by the physical-chemical and microbiological analysis of the eggs and the bone resistance to the break were submitted to analysis of variance, in case of effects of the different production systems, the Tukey's test was applied at 5% of probability for comparison of the means. The physical-chemical quality was also favored by the two production systems, indicating that the experimental circumstances provided adequate conditions for the formation of good quality eggs. The cage system did not disfavor the bony characteristics of the hens, indicating that at suitable densities, the cage may not exert a detrimental factor to bone quality. The cage-free production system worsened shell contamination by proving that nesting eggs are more contaminated compared to those produced in cages.

Objective: To investigate the prevalence of early childhood maltreatment and associations with later sexual behavior among adult substance users. Methods: A cross-sectional study enrolled 134 substance dependents who sought outpatient care in São Paulo, Brazil. Childhood trauma prevalence was assessed using the Childhood Trauma Questionnaire (CTQ). The Sexual Addiction Screening Test (SAST), drug of choice (DOC), and sexual behavior were also investigated. Results: The sample was composed predominantly of single adult males (76.1%), with alcohol as the DOC (73.9%). Experiences of emotional neglect (88.1%), emotional abuse (80.6%), physical neglect (78.4%), physical abuse (64.2%), and sexual abuse (31.3%) were prevalent. Women were more likely to have been sexually abused (OR 2.9, 95%CI 1.15-7.61) and physically abused (OR 3.7, 95%CI 1.31-10.6) in childhood. Those who were sexually abused in adulthood were more likely to have suffered physical abuse in childhood (OR 6.9, 95%CI 1.45-11.8). The odds of having been sexually abused in childhood were higher among subjects who reported to have exchanged sexual favors for drugs (OR 5.7, 95%CI 1.35-9.64) and to have been sexually abused in adulthood (OR 6.1, 95%CI 5.2-12.36). Conclusion: Physical and sexual abuse in childhood are highly prevalent in substance-dependent adults, and are associated with sexual revictimization and high-risk sexual behavior in adulthood.

Resumen Spodoptera frugiperda (Lepidoptera: Noctuidae) es una plaga que provoca daños en los cultivos de fríjol al reducir el área foliar y destruir las estructuras reproductivas.Este trabajo tuvo como objetivo evaluar los tipos y niveles de resistencia de cultivares de frijol a S. frugiperda. Los cultivares evaluados fueron: BRS Ametista, Pérola, BRS Notável, BRS Realce, Jalo Precoce, BRS Campeiro, BRS Agreste, BRS Cometa, BRS Executivo y BRS Pitanga, en el Laboratorio de Entomología Agrícoladel Instituto Federal Goiano, Campus de Urataí, Brasil. Antixenosis, a libre y no libre escogencia y antibiosis se evaluaron en laboratorio (25 ± 2 °C, 70 ± 10 % HR y fotoperiodo 14 h). Los cultivares BRS Pitanga, BRS Executivo, BRS Notável y BRS Campeiro presentaron antixenosis y BRS Realce antibiosis a S. frugiperda. Sin embargo, no se sabe si los niveles de resistencia, exhibidos en el laboratorio, son suficientemente altosque representen un valor económico de campo para los agricultores. Por lo tanto, el próximo paso es evaluar, en condiciones de campo, los cultivares que mostraron mayor resistencia enlas pruebas de laboratorio. Si las evaluaciones de campo indican niveles de resistencia suficientes, para tener un valor práctico, estos cultivares pueden utilizarse como fuentes en el programa de mejoramiento o ser utilizados directamente por los agricultores.

Abstract Spodoptera frugiperda (Lepidoptera: Noctuidae) damages bean crops, resulting in decreased leaf area and destruction of reproductive structures. This study aimed to evaluate the types and levels of resistance of bean cultivars to S. frugiperda. Thebeancultivars evaluatedwere: BRS Ametista, Pérola, BRS Notável, BRS Realce, Jalo Precoce, BRS Campeiro, BRS Agreste, BRS Cometa, BRS Executivo and BRS Pitanga, in the Laboratory of Agricultural Entomology of the Goiano Federal Institute, Urutaí Campus, Brazil. Tests to identify levels of antixenosis, in free-choiceand no-choice tests, and antibiosiswere performed in the laboratory (25 ± 2 °C, 70 ± 10 % R.H. and photophase of 14 h).The cultivars BRS Pitanga, BRS Executivo,BRS Notável and BRS Campeiro presented antixenosis and BRS Realce antibiosis to S. frugiperda. However, it is not known whether the levels of resistance exhibited in the laboratory are sufficiently high to be of any economic value to agriculture. Therefore, the next step is to evaluate, under field conditions, the cultivars showing the most resistance in laboratory tests. If field evaluations indicate sufficient levels of resistance to be of practical value, these cultivars may be used as donor sources in the breeding program or may be used directly by farmers.

Abstract In a previous study, we reported the antispasmodic and gastroprotective effects of the Serjania caracasana (Jacq.) Willd., Sapindaceae, extract. In the present study, we evaluated the LD50, hemolytic and antispasmodic activities of its fractions and characterized its major constituents by isolation and GC–MS. The animals showed non-toxic symptoms with oral doses up to 2000 mg/kg, suggesting a safe oral administration. Furthermore, a low hemolytic activity was detected for the saponin fraction. Antispasmodic activity of the fractions was evaluated through carbachol-induced contractions in rat ileum. The hexane fraction was the most potent (IC50 68.4 ± 5.9 µg/ml) followed by the dichloromethane fraction (IC50 161.3.4 ± 40.7 µg/ml). Butanol fraction was the less effective (IC50 219.8 ± 60.3 µg/ml). The phytochemical study of the S. caracasana fractions afforded the isolation of friedelin, β-amyrin, allantoin and quercitrin. This is the first time that the presence of allantoin and quercitrin in the Serjania genus has been reported. Among the isolated compounds and those characterized by GC–MS, β-amyrin and β-sitosterol were present in the most active fractions, hexane and dichloromethane, and they may be related to its antispasmodic activity. In addition, spathulenol was only found in the hexane fraction and its presence might justify the highest antispasmodic activity observed for this fraction.

RESUMO: O presente estudo foi realizado com o objetivo de se determinar a ocorrência de anticorpos anti-Brucella spp. em 1.940 amostras de sangue de suínos, das quais 1.594 amostras eram de 30 granjas comerciais, de sete diferentes Estados, coletadas durante o abate dos animais, e 346 amostras de 56 criações de subsistência da região de Jaboticabal, Estado de São Paulo, Brasil. Todas as amostras foram submetidas ao teste do Antígeno Acidificado Tamponado (AAT) e consideradas positivas caso ocorresse aglutinação. Quando positivas, as amostras eram submetidas ao teste de Reação de Fixação de Complemento (RFC) como teste confirmatório. Dentre as 1.594 amostras de suínos de granjas comerciais, duas se mostraram sensíveis ao AAT, porém, quando foram submetidas à RFC, ambas apresentaram reação negativa, levando a uma porcentagem de ocorrência de 0%. Já entre as 346 amostras de criações de subsistência, duas foram positivas ao AAT, sendo que apenas uma apresentou reação positiva no teste confirmatório, cujo título foi de 1:8. Desta forma, a ocorrência foi de 0,29%, resultado importante para demonstrar a melhoria do status sanitário dos rebanhos de subsistência brasileiros, apesar das condições precárias em que vivem.

ABSTRACT: The aim of this study was to determine the occurrence of antibodies anti-Brucella in 1,940 swine blood samples. Out of the 1,940 sera samples, 1,594 were from 30 intensive pig farming from seven different states, collected during the slaughtering of animals, and 346 samples from 56 non-technified (subsistence) pig herds from Jaboticabal region, São Paulo State, Brazil. All samples were tested by Buffered Plate Acidified Antigen (BPAA) and considered positive in case of agglutination. If positive, the samples were tested by Complement Fixation Reaction (CFR) as a confirmatory test. Out of the 1,594, two were positive for BPAA but negative for CFR, so the occurrence was 0%. Among the 346 samples, two were positive for BPAA but only one was positive in the confirmatory test, whith a titer of 1:8. Thus, the occurrence was 0.29%, an important result to demonstrate the improvement of the sanitary status of Brazilian non-technified pig herds, despite the low conditions of production.

This study aimed to evaluate the effects of nitrogen availability in fertigation and rainfed management, as well as their interactions with the incidence of and damage caused by D. saccharalis and red rot in sugarcane. The experiment consisted of four treatments (0 and 150 kg ha–1 of N-fertilizer with irrigation; 0 and 150 kg ha–1 of N-fertilizer in rainfed management) in a randomized complete block design with four replications. The evaluated parameters were the number of holes and internodes with red rot per meter of cultivation, stalk yield and sugar content. In the laboratory (T = 25 ± 2 °C; R.H. = 70 ± 10%: 12:12-L:D), we evaluated the attractiveness and consumption of fragments of stalks from the different treatments for fourth instar larvae through choice and no-choice tests in a randomized complete block design with ten replications. Nitrogen fertilization via irrigation has favorable effects on borer-rot complex and leads to higher gains in stalk and sugar yields when compared to rainfed management. The increments of stalk and sugar yields due to nitrogen fertilization compensates for the increase in borer-rot complex infestation. In laboratory tests, D. saccharalis larvae were similarly attracted to all treatments regardless of the doses of N-fertilizer or the water regimes evaluated. However, fragments of sugarcane stalks produced with nitrogen fertilization were consumed more by D. saccharalis in both water regimes.

Cardiovascular diseases (CVDs) are known to be associated with poor sleep quality in general populations, but they have not been consistently associated with specific work schedules. Studies of CVD generally do not simultaneously consider sleep and work schedules, but that approach could help to disentangle their effects. We investigated the association between insomnia and a self-reported physician diagnosis of CVD in day and night workers, considering all sleep episodes during nocturnal and diurnal sleep. A cross-sectional study was conducted in 1307 female nursing professionals from 3 public hospitals, using baseline data from the “Health and Work in Nursing - a Cohort Study.” Participants were divided into two groups: i) day workers with no previous experience in night shifts (n=281) and whose data on insomnia were related to nocturnal sleep and ii) those who worked exclusively at night (n=340) and had data on both nocturnal and diurnal sleep episodes, as they often sleep at daytime. Multiple logistic regression analysis was performed. Among day workers, insomnia complaints increased the odds of CVD 2.79-fold (95% CI=1.01-6.71) compared with workers who had no complaints. Among night workers, reports of insomnia during both nocturnal and diurnal sleep increased the odds of reported CVD 3.07-fold (95% CI=1.30-7.24). Workers with insomnia had similar probabilities of reporting CVD regardless of their work schedule, suggesting a relationship to insomnia and not to night work per se. The results also highlighted the importance of including evaluation of all sleep episodes (diurnal plus nocturnal sleep) for night workers.

El cogollero del maíz, Spodoptera frugiperda (Lepidoptera: Noctuidae) es una especie polífaga de cultivos. Los cambios en los sistemas de cultivo del algodón han aumentado la importancia de esta plaga en la región de El Cerrado, Brasil. Este estudio tuvo como objetivo evaluar los tipos de resistencia de las variedades de algodón (Gossypium hirsutum) por la no preferencia para oviposición y antibiosis de S. frugiperda laboratorio (27 ± 2 ºC, 70 ± 10% HR y fotoperiodo 14 h). Dos ensayos se realizaron para evaluar la no-preferencia para oviposición y alimentación, a libre y no libre escogencia, en un diseño experimental de bloques. Las hojas de las variedades DeltaOpal®, NuOpal®, FMX 993®, FMT 701®, FMX 910® y FMX 996® se ofrecieron diariamente a las larvas de S. frugiperda. Se analizaron la duración de cada estadio larval y pupal, peso de larvas a los 10 días, peso de pupa a las 24 horas, la longevidad y fecundidad de los adultos. La variedad NuOpal® fue la más resistente a S. frugiperda, al afectar el desarrollo biológico de esta plaga, presentando resistencia de los alimentos no preferidos. Las larvas de S. frugiperda alimentadas sobre algodón no Bt y sus pupas tuvieron mayor peso, más corto período larval, mayor adulto longevidad y oviposición y una mayor viabilidad total.

The fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae) is a polyphagous pest species of cultivated plants. Changes in cotton crop systems are increasing the importance of this pest in cotton in the El Cerrado region of Brazil. This work aimed to evaluate resistance types of cotton (Gossypium hirsutum) varieties by non-preference to oviposition and feeding along with antibiosis to S. frugiperda in the laboratory (27 ± 2 ºC, 70 ± 10% R.H. and photophase of 14 h). Two tests were performed to evaluate the non-preference to oviposition and feeding, one with free choice in a randomized block design and another in a completely randomized design. Leaves of the cotton varieties DeltaOpal®, NuOpal®, FMX 993®, FMT 701®, FMX 910® and FMX 996® were offered daily to S. frugiperda larvae. The presence of antibiosis was evaluated by the duration of each instar and of the larval and pupal stages, larval and pupal biomass, and adult longevity and fecundity. The NuOpal® variety was the most resistant to S. frugiperda. Spodoptera frugiperda fed on non-Bt cotton had heavier pupae and larvae, shorter development time for the larval stage, longer adult longevity, and a higher rate of oviposition and total viability when compared to the Bt cotton varieties.

A manutenção de aves em cativeiro reúne condições que favorecem a disseminação de doenças infecciosas, sendo a Salmonella uma dessas doenças infecciosas que acomete os psitacídeos. Portanto o objetivo do presente estudo foi isolar e identificar Salmonella spp. em Psittaciformes mantidos em criatórios comerciais e conservacionistas da Região Metropolitana de Fortaleza. Para o estudo, foram coletados swabs cloacais de 182 psitacídeos clinicamente sadios. Os resultados mostraram que três psitacídeos avaliados (1,65%) foram positivos: Amazona aestiva (Salmonella Lexington), Ara chloroptera (Salmonella Saintpaul) e Melopsittacus undulatus (Salmonella Newport). De acordo com a literatura científica, não há registro desses sorotipos em psitacídeos. Esta pesquisa evidenciou uma baixa prevalência de Salmonella spp. em Psittaciformes mantidos em criatórios comerciais e conservacionistas da Região Metropolitana de Fortaleza.

This study showed a low prevalence of Salmonellaspp. in captive psittacines from zoos and a commercial establishment of Fortaleza. None of the isolated serotypes (S. Lexington, S. Saintpaul and S. Newport) have yet been reported in Amazona aestiva, Ara chloropteraor Melopsittacus undulatus. However, the fact that most birds presented negative for Salmonellaspp. may not imply the absence of this pathogen in these birds, since the intermittent excretion is a well-known characteristic of this microorganism.

Estudou-se o efeito da substituição do farelo de soja da ração por pastejo controlado de trevo-branco (Trifolium repens L.) sobre o comportamento ingestivo de vacas da raça Holandesa em pastejo de azevém (Lolium multiflorumLam.). Utilizaram-se dois grupos de animais, com média de 20 vacas agrupadas por produção, período de lactação e peso corporal, em delineamento experimental em blocos ao acaso. Um grupo recebeu, diariamente, 3kg de suplemento energético e teve acesso controlado à pastagem de trevo-branco por aproximadamente duas horas e meia (TB); o outro recebeu o mesmo suplemento, adicionado de quantidade de proteína equivalente ao consumo diário no tratamento anterior via trevo, na forma de farelo de soja (FS). Para a avaliação de comportamento, procedeu-se à observação e ao registro do ritmo de atividade dos animais, no período de pastejo em azevém durante dois dias consecutivos, quinzenalmente. Observou-se maior tempo de pastejo em minutos (min), 212,00 versus 194,24min dia-1, e frequência de bocados (bocado), 67,78 versus 64,09 bocado min-1, entre os animais do tratamento FS, em relação ao TB. Não houve diferença no consumo de azevém entre os tratamentos, com valores de 3,65 e 4,11kg vaca-1 dia-1de matéria seca para TB e FS, respectivamente, o que sugere adequada adaptação dos animais às duas situações estudadas.

The effect of the replacement of soybean meal in the ration with controlled grazing of white clover (Trifolium repens L.) on the ingestive behavior of cows of the holstein breed grazing on annual ryegrass (Lolium multiflorum Lam.) was studied. Two groups of animals with an average of 20 cows grouped by production, lactation period and body weight were used in a randomized block experimental design. One group received 3kg from energy supplement daily and had controlled access to the white clover pasture for approximately 2.5 hours (TB); the other received the same supplement, added of a quantity of protein equivalent to daily intake in previous treatment via white clover, in the form of soybean meal (FS). For behavior assessment the observation and recording of the rhythm of activity of the animals, during the grazing period in ryegrass for two consecutive days, fortnightly was done. The longest grazing time in minutes (min), 212.00 versus 194.24min day-1, and bite frequency (bite), 67.78 versus 64.09 bite min-1, between the animals from treatment FS, when compared to TB was observed. There was no difference in the intake of ryegrass between the treatments, with values of 3.65 and 4.11kg cow-1 day-1 of dry matter for TB and FS, respectively, suggesting adequate adaptation of the animals in the two situations studied.

Avaliou-se a composição do leite de animais em pastejo de azevém (Lolium multiflorum Lam.) alimentados com trevo branco (Trifolium repens L.) como substituição ao componente proteico da ração (farelo de soja), em porcentagens de proteína, lactose, sólidos totais e contagem de células somáticas. Utilizaram-se dois grupos com oito vacas da raça Holandesa, agrupados por produção, período de lactação e peso corporal, em delineamento em blocos ao acaso. Um grupo recebeu, diariamente, 3kg de suplemento energético subtraído de farelo de soja e teve acesso à pastagem de trevo branco por, aproximadamente, 2,5 horas (TB); o outro recebeu o mesmo suplemento, adicionado de quantidade de proteína equivalente ao consumo diário no tratamento anterior via trevo, na forma de farelo de soja (FS). Foram observadas diferenças significativas para teor de proteína e lactose, sendo os maiores valores encontrados de proteína em TB (3,02%) e de lactose em FS (4,64%). Para as demais variáveis não houve diferença, com valores de 10,40 e 10,39% de sólidos totais e 182,88 e 153,53 (x1000) células somáticas em TB e FS, respectivamente, mostrando que a utilização dessa fonte alternativa de proteína foi eficiente.

Was evaluated the composition of milk from animals grazing annual ryegrass (Lolium multiflorum Lam.) fed with white clover (Trifolium repens L.), as a replacement for the protein component of the ration (soybean meal), in percentages of protein, lactose, total solids and somatic cell counts. Were used two groups with eight Holstein cows, grouped by production, lactation period and body weight, in a randomized block design. One group received 3kg of energetic supplement subtracted of soybean meal daily and had access to the white clover pasture for approximately 2.5 hours (TB); the other received the same supplement, added of a quantity of protein equivalent to daily intake in previous treatment via white clover, in the form of soybean meal (FS). Significant differences were observed for protein and lactose content, with the highest values found for protein on TB (3.02%) and lactose on FS (4.64%). For the other variables there was no difference, with values from 10.40 and 10.39% of total solids and 182.88 and 153.53 (x1000) somatic cells on TB and FS respectively, showing that the use of this alternative source of protein was efficient.

Este estudo tem por objetivo identificar o efeito do armazenamento térmico na manutenção da qualidade, bem como, no controle do escurecimento da polpa durante o armazenamento refrigerado de cultivares de pêssegos tardios. Os frutos foram colhidos fisiologicamente maturos. Os frutos foram submetidos às temperaturas de 20 ± 0,5ºC e 75 ± 3% de UR, em câmara frigorífica, durante 0, 24 ou 48. Após, os frutos foram mantidos a 0 ± 0,5ºC e 92 ± 3% de UR, por 28 dias. Ao final do experimento, os frutos das cultivares de polpa amarela, independentemente de armazenamento refrigerado, não apresentaram sinais de escurecimento interno, apresentaram qualidade adequada para comercialização. Quando não submetidos ao armazenamento refrigerado, após 14 dia de armazenamento, mais dois sem refrigeração, os frutos de polpa branca apresentaram escurecimento da polpa. A partir dos resultados observados na análise de sólidos solúveis, acidez titulável e desenvolvimento de podridões, esses frutos apresentaram um maior nível de amadurecimento. O condicionamento térmico de 48 horas, nas duas cultivares, resultou em um amadurecimento maior e apodrecimento dos frutos. Armazenamento refrigerado por 24 horas foi eficiente no controle de escurecimento da polpa e na manutenção da qualidade das cultivares de pêssego de polpa branca.

The purpose of this study was to identify the effect of delayed storage on the maintenance of the quality and on the control of pulp browning during cold storage of late peach cultivars. The fruit was harvested at the mature-green stage. All cultivars were exposed to temperatures of 20 ± 0.5ºC and 75 ± 3% of moisture in a cold room for 0.24, or 48 hours. Afterwards, the peaches were kept at 0 ± 0.5ºC and 92 ± 3% of R.H. for 28 days. In the end, the yellow pulp cultivars, regardless of temperature and length of delayed storage, did not present signs of internal browning and were of adequate quality for commercialization. When they were not subjected to delayed storage, the white pulp peaches presented pulp browning after 14 days of cold storage plus two days out of the cold room. From the results observed in the analysis of soluble solids, titratable acidity and decay development, these peaches showed an increased level of ripening. In both cultivars, delayed storage for 48 hours resulted in increased ripening and decay. Delayed storage for 24 hours was effective in controlling pulp browning and in maintaining the quality of the white pulp peach cultivars.

Este trabalho teve como objetivo verificar a ocorrência das formas de resistência, tais como: a não preferência para oviposição, a não preferência para alimentação e a antibiose, em variedades de algodoeiro (Gossypium hirsutum L.), à Alabama argillacea (Hubner, 1818), em experimentos de laboratório (27 ± 2 ºC, 70 ± 10% de U.R. e fotofase de 14 horas). Para avaliar a não preferência para oviposição e para a alimentação em teste com chance de escolha, adotou-se o delineamento em blocos casualizados e, no teste sem chance, o inteiramente casualizado. Para avaliar a antibiose, foram fornecidas às larvas, diariamente, folhas das variedades DeltaOpal, NuOpal, FMT 701, FMX 910 e 20 FMX 996. Durante este processo, verificou-se a duração de cada fase do inseto, avaliando-se a massa de larvas aos dez dias de idade, massa de pupas com 24 horas, período larval, pré-pupal e pupal, longevidade de adultos, viabilidade total e fecundidade. As variedades NuOpal e FMT 701 apresentam resistência do tipo não preferência para alimentação. As variedades NuOpal, FMT 701 e FMX 910 apresentam resistência do tipo antibiose em relação a A. argillacea.

This work aimed to test the occurrence of types of resistance in cotton varieties (Gossypium hirsutum L.) including non-preference to oviposition and feeding and antibiosis to Alabama argillacea (Hubner, 1818), in laboratory experiments (27±2 ºC, 70±10% de R.H. and photophase of 14 hours). The experiment to evaluate the non-preference for oviposition and feeding in free choice tests used a randomized block design, while the tests without free choice used a completely randomized design. To evaluate antibiosis, leaves of the varieties DeltaOpal, NuOpal, FMT 701, FMX 910 e FMX 996 were fed to the larvae daily. The duration of each insect phase, the larvae mass in the 10th day, the pupa mass with 24 hours, the larva and pupa stage, the adult longevity, total viability and fecundity were recorded. The varieties NuOpal and FMT 701 showed resistance by non-preference for feeding. The varieties NuOpal, FMT 701 and FMX 910 showed resistance by antibiosis to A. argillacea.

Foram realizados três experimentos com o objetivo de avaliar o efeito da suplementação de minerais na forma orgânica na dieta de codornas japonesas na fase de postura sobre o desempenho e a qualidade de ovos das aves. Os níveis de minerais utilizados por kg de ração, para cada experimento, foram: controle, 0,35, 0,70 e 1,05mg de Se orgânico (experimento 1); controle, 50, 100 e 150mg de Zn orgânico (experimento 2) e controle, 60, 120 e 180mg de Mn orgânico (experimento 3). As aves foram distribuídas em delineamento inteiramente ao acaso, sendo oito aves por parcela e seis repetições por tratamento. Foram avaliadas as características de desempenho - consumo diário de ração, peso dos ovos, porcentagem de postura, conversão alimentar por massa de ovos e por dúzia de ovos e viabilidade - e qualidade dos ovos - unidade Haugh, índice gema, porcentagens de casca, albúmen e gema, espessura de casca e gravidade específica. O Zn orgânico suplementado à dieta melhorou o desempenho das aves e a qualidade dos ovos, o Mn orgânico melhorou a qualidade da casca e reduziu o peso dos ovos e o Se não apresentou efeitos sobre as características avaliadas.

Three experiments were carried out to evaluate the effect of minerals in organic form in diet supplementation in Japanese quails performance. The levels of minerals used per kg of diet for each experiment were: Experiment 1: control, 0.35; 0.70 and 1.05mg organic; Experiment 2: control, 50; 100 and 150mg organic Zn; and Experiment 3: control, 60; 120 and 180mg organic Mn. The birds were randomly allotted in treatments with eight birds per experimental unit and six replicates per treatment. Performance traits of the quails estimated by daily feed intake, egg weight, egg production, feed conversion by egg mass and per dozen eggs and viability, and egg quality measured by Haugh unit, yolk index, shell, albumen and yolk percentage, shell thickness and specific gravity were evaluated. The organic Zn diet supplementation improved bird performance and egg quality, the organic Mn diet improved eggshell quality and reduced egg weight, and the Se diet did not affect the evaluated characteristics.
