RESUMO A produção de amendoim tem crescido anualmente no Brasil. Com as secas que ocorrem frequentemente em todas as regiões brasileiras, é necessário identificar germoplasma precoce para ser utilizado em trabalhos de melhoramento visando à adaptação ambiental. Aqui, uma mini coleção de amendoim foi estudada com o objetivo de selecionar germoplasma para uso posterior em procedimentos de melhoramento, com foco em ambiente com restrição hídrica. Doze características agronômicas foram adotadas e posteriormente utilizadas em métodos multivariados, baseados em modelos hierárquicos (UPGMA) e dispersão gráfica (variáveis canônicas), visando identificar agrupamentos de acessos precoces. Diferenças estatísticas significativas foram encontradas para a maioria das variáveis, indicando variabilidade genética nos acessos estudados. Com base nas análises multivariadas, verificou-se coerência na formação de três agrupamentos, um deles (G3: PI-268-689 e AHK-85-3) aglomerou os acessos mais promissores para produção de vagens e eficiência reprodutiva, previamente identificados na análise de variância. Portanto, ambos germoplasma são recomendados para uso em trabalhos de melhoramento voltados para o ambiente com restrição hídrica.

ABSTRACT Peanut production is growing annually in Brazil, but with frequent droughts throughout the country, it is necessary to identify an earliness germplasm for the improved environmental adaptation of peanuts. Here, a mini-core collection of peanuts was studied to select germplasms for further use in breeding, with a focus on dry environments. Twelve agronomic traits were adopted and later used in multivariate methods based on hierarchical models (UPGMA) and graphical dispersion (canonical variables), which aimed to identify earliness accession clusters. Statistically significant differences were found for most traits, indicating that there was genetic variability among accessions. Multivariate analyses subsequently revealed coherence in the formation of three clusters, one of which (G3: PI-268-689 and AHK-85-3) combined the most promising accessions for pod production and reproductive efficiency, previously identified through analysis of variance. Therefore, both germplasms are recommended here for use in future breeding studies focused on water-restricted environments.

Abstract: En | Text: En | PDF: En

Supported Au-Pd nanoparticles (NPs) have been extensively studied in alcohol oxidation reactions. However, few studies use reducible metal oxides as support, which can activate oxygen molecules and boost the selectivity of the reaction. In this work, Au-Pd NPs were supported on α-MoO3 and evaluated in the selective oxidation of cinnamyl alcohol without solvent. The Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and X-ray photoemission spectroscopy (XPS) analyses showed that the catalyst is richer in oxygen vacancies than the support, being probably responsible for the stability of the NPs (average size 4.62 ± 0.15 nm) and the high conversion and selectivity for the oxidation of cinnamyl alcohol. Furthermore, experiments have shown that the Au:Pd molar ratio influences the catalytic performance and can be optimized by controlling temperature, pressure, and reaction time. The catalyst proved to be active and selective for cinnamaldehyde in short reaction times. It showed satisfactory performance at 30 min and its best activity at 1 h with 94% conversion and 87% selectivity, without loss of activity and selectivity after four runs under the same reaction conditions.

Abstract Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00–7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08–3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12–4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93–0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95–0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19–0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16–0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

Abstract: En | Text: En | PDF: En

The Brazilian Cerrado biome is considered one of the 25 hotspots worldwide that contain bioactive compounds due to its great biodiversity; however, the reduction of its native area over time due to the expansion of urbanization and agribusiness may have compromised knowledge of its biological variety. In this context, knowledge about Cerrado species can contribute to its biodiversity preservation. This study aims to describe the isolation, molecular architecture and theoretical calculations of the compound (3S,8S,9S,10R,13R,14S,17R)-17-[(2R,5R)-5 ethyl -6-methylheptan-2 yl]-10,13 dimethyl 2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H cyclopenta[a]phenanthren-3 ol, extracted from the Brazilian Cerrado Miconia burchellii plant. The supramolecular arrangement was described by Hirshfeld surface analysis, demonstrating the intermolecular interactions in the crystalline packing. The structure-property relationship shows the electrostatic potential map analysis, which reveals that the oxygen region is susceptible to electrophilic attack, and the frontier molecular orbital confirmed the kinetic stability of this compound. This study represents another step forward in the knowledge of compounds with pharmacological and medicinal properties extracted from the Cerrado.

RESUMO O amendoim rasteiro é conhecido pela alta produtividade, porém as plantas são tardias para florar e maturar as vagens. A combinação desses caracteres e produção de vagens é largamente almejada no melhoramento dessa oleaginosa. Índices de seleção são ferramentas úteis para auxiliar no melhoramento da cultura. Neste trabalho foram usados sete índices de seleção combinados com pesos econômicos, com objetivo de estimar ganhos genéticos superiores e equilibrados em uma população de amendoim runner. Onze genótipos foram cultivados em três ambientes na região Nordeste sob o delineamento de blocos ao acaso com cinco repetições. Foram utilizados os seguintes índices: Smith e Hazel (SH), Pesek e Baker (PB), Williams (W), Elston (E), Subandi (S), índice de Cruz (GI) e Mulamba e Mock (MM), que foram combinados com os pesos econômicos: W1- peso 1 para todas as características avaliadas; PT - traços primários e secundários; CGv - coeficiente de variação genética; SDg - desvio padrão genético e coeficiente b, obtido por meio de regressão multivariada. Embora a população seja geneticamente uniforme, diferenças estatísticas foram encontradas indicando variabilidade genética suficiente para gerar progresso na seleção. As combinações envolvendo os caracteres de precocidade (B e FPM) não foram satisfatórias para ganhos de produção. O índice baseado no ranks de MM combinado com W1 para todas as características foi o melhor por indicar ganhos mais equilibrados. As cultivares Florunner, Cavalo, LGoPE-06 e LViPE-06 são germoplasma promissores para garantir satisfatórios ganhos de seleção, baseando-se nas medias de produção e alta herdabilidade dos caracteres avaliados.

ABSTRACT Runner peanuts are known for their high pod yields, but are late to flowering and pod maturation, and the optimal combination of these traits with pod yield is widely desired for peanut improvement. Selection indexes are useful tools for crop breeding. In this study, seven selection indexes combined with economic weights were used in a peanut population to estimate the superior and balanced genetic gains. Eleven runner genotypes were grown in three environments in the Northeast region of Brazil under a randomized block design with five replicates. The following indices were used: Smith and Hazel, Pesek and Baker, Williams, Elston, Subandi, Cruz, and Mulamba & Mock, in combination with the following economic weights: weight 1 for all evaluated traits, primary and secondary traits, genetic variation coefficient, genetic standard deviation, and b coefficient, obtained via multivariate regression. Although the population is genetically uniform, statistical differences were found, indicating sufficient genetic variability to generate selection progress. The combinations involving earliness traits were not satisfactory for production gains. The index based on the Mulamba & Mock rankings combined with weight 1 for all traits proved the optimal combination, as indicated by the most balanced gains. The cultivars Florunner, Cavalo, LGoPE-06, and LViPE-06 are promising germplasm for ensuring satisfactory selection gains based on production means and high heritability of the most evaluated traits.

Abstract: Protected areas are frequently established to prevent declines in biodiversity, but their effectiveness in preserving biodiversity can depend on how land outside their borders is managed. We evaluated how land use changes from 1989 to 2016 in the Reserva de la Biosfera Sierra del Abra Tanchipa (RBSAT) landscape might affect the role of the RBSAT for conservation of biodiversity, with an emphasis on conservation of jaguars, a keystone species. We estimated the rate of land use change within and surrounding the RBSAT, a 215 km2 natural reserve in San Luis Potosí, Mexico, from 1989 to 2016 using supervised classifications of satellite imagery. We also analyzed the distribution of two GPS collared male jaguars. The RBSAT and surrounding landscape became increasingly fragmented and impacted by human use over the previous ca. 30 years. The largest increases were seen in infrastructure and intensive agriculture, while the largest decreases were seen in pasture, tropical deciduous forest, and secondary vegetation. Jaguars were located more frequently than expected in secondary vegetation, the most common cover class, which decreased from 34.8 % of the landscape to 32.1 % by 2016. Only 23 % of jaguar locations fell within the boundaries of the RBSAT, due to increases in preferred habitat attributes of jaguars and prey outside the Reserve. Increasing fragmentation compromises the RBSAT’s role as a biodiversity reserve, especially for interior-dependent species. Fragmentation and edge habitats in combination with increasing agriculture enhance suitability of the landscape surrounding the RBSAT for prey of jaguar, and only 23 % of jaguar locations were within the RBSAT itself. This increases the likelihood of jaguar-related conflicts in surrounding communities. Regional landscape planning should include policies that incentivize practices that maintain remaining larger habitat patches and minimize the likelihood of human-wildlife conflicts.

Resumen: Las áreas protegidas se establecen con frecuencia para evitar la disminución de la biodiversidad, pero su eficacia para preservar la biodiversidad puede depender de cómo se gestione la tierra fuera de sus fronteras. Se evaluó cómo los cambios en el uso del suelo de 1989 a 2016 en el paisaje de la Reserva de la Biosfera Sierra del Abra Tanchipa (RBSAT) podrían afectar el papel de la RBSAT para la conservación de la biodiversidad, con énfasis en la conservación de los jaguares, una especie clave. Se estimó la tasa de cambio de uso del suelo dentro y alrededor de la RBSAT, una reserva natural de 215 km2 en San Luis Potosí, México, de 1989 a 2016 utilizando clasificaciones supervisadas de imágenes satelitales. También se analizó la distribución de dos jaguares machos con collar GPS. La RBSAT y el paisaje circundante se fragmentaron cada vez más y se vieron afectados por el uso humano durante los ca. 30 años. Los mayores aumentos se observaron en infraestructura y agricultura intensiva, mientras que las mayores disminuciones se observaron en pastos, bosque tropical caducifolio y vegetación secundaria. Los jaguares se ubicaron con mayor frecuencia de lo esperado en la vegetación secundaria, la clase de cobertura más común, que disminuyó del 34,8 % del paisaje al 32,1 % en 2016. Solo el 23 % de las ubicaciones de jaguares se ubicaron dentro de los límites de la RBSAT, debido a aumentos en la preferencia. atributos de hábitat de jaguares y presas fuera de la Reserva. La creciente fragmentación compromete el papel del RBSAT como reserva de biodiversidad, especialmente para las especies dependientes del interior. La fragmentación y los hábitats de borde en combinación con el aumento de la agricultura mejoran la idoneidad del paisaje que rodea a la RBSAT para las presas del jaguar, y solo el 23 % de las ubicaciones de los jaguares estaban dentro de la propia RBSAT. Esto aumenta la probabilidad de conflictos relacionados con jaguares en las comunidades aledañas. La planificación del paisaje regional debe incluir políticas que incentiven prácticas que mantengan los parches de hábitat más grandes restantes y minimicen la probabilidad de conflictos entre humanos y vida silvestre.

Abstract Objective: To evaluate cardiac function and structural changes in children of diabetic mothers in the fetal and neonatal period using Doppler-echocardiographic data. Method: A prospective, descriptive observational study conducted in a private and tertiary care service for high-risk pregnant women. It included 48 children of mothers with gestational diabetes mellitus (GDM) considered clinically compensated during pregnancy, with a single fetus and absence of malformations. Myocardial thickness, shortening fraction, left ventricular (LVMPI) and right ventricular (RVMPI) myocardial performance index, and mitral and tricuspid valve E/A ratio were evaluated in 96 echocardiographic exams with Doppler. Results: The hypertrophic cardiomyopathy was 29% vs 6% p = 0.006 in the prenatal and postnatal periods respectively. The shortening fraction was 0% vs 6% p = 0.242 in the fetuses and newborns respectively. The myocardial performance index of the right ventricle was 12% vs 54% p ≤ 0.001, and on the left ventricle 27% vs 60% p = 0.001 in the prenatal and postnatal periods respectively. The ratio of mitral valve E/A waves was 6% vs 50% p ≤ 0.001 and the ratio of tricuspid valve E/A waves was 0% vs 27% p 0.001 in the fetuses and newborns respectively. Conclusion: A decrease in the rate of myocardial hypertrophy and changes in cardiac function parameters were observed in the fetal and neonatal periods.

RESUMO Objetivou-se com este estudo estimar a evapotranspiração da bananeira (Musa spp.) num perímetro irrigado do município de Barbalha, CE, utilizando o modelo Surface Energy Balance Algorithm for Land (SEBAL) e comparar estes resultados com os estimados através do Método de Penman-Monteith. Foram utilizadas imagens de satélite Landsat-8 OLI/TIRS dos dias 22/05/2016, 10/08/2016 e 29/10/2016 e os dados de temperatura, umidade relativa do ar, velocidade do vento e irradiância solar, obtidos de uma estação meteorológica automática, instalada próxima da área experimental. Foi feito o empilhamento das bandas e o recorte das imagens empilhadas, em seguida, realizaram-se as operações matemáticas e a estimativa da evapotranspiração, cujos valores reais diários da bananeira, estimados pelo algoritmo SEBAL foram de 4,70; 5,00 e 6,50 mm, respectivamente, para os dias 22/05/2016, 10/08/2016 e 29/10/2016. Comparando a ETr diária dada pelo SEBAL com a obtida pelo método de Penman-Monteith, observaram-se erros absolutos de 0,26; 0,44 e 0, 64 mm d-1 para os dias 22/05/2016, 10/08/2016 e 29/10/2016, respectivamente. Estes erros estão dentro dos intervalos aceitos na literatura.

ABSTRACT The study aimed to estimate the evapotranspiration of banana (Musa spp.) in an irrigated perimeter of the municipality of Barbalha, CE, Brazil, using the Surface Energy Balance Algorithm for Land (SEBAL) model and to compare these results with those estimated using the Penman-Monteith method. Landsat-8 OLI/TIRS satellite images of May 22, 2016, August 10, 2016, and October 29, 2016 and data on temperature, relative humidity, wind speed and solar irradiance, obtained from an automatic weather station, installed close to the experimental area were used. The bands were stacked, and the stacked images were cut, then mathematical operations and evapotranspiration estimation were performed, whose actual daily banana values, estimated by the SEBAL algorithm, were 4.70; 5.00 and 6.50 mm, respectively, for May 22, August 10, and October 29, 2016. Comparing the daily ETr given by SEBAL with that obtained by the Penman-Monteith method, absolute errors of 0.26, 0.44, and 0.64 mm d-1 were observed for May 22, August 10, and October 29, 2016, respectively. These errors are within the ranges accepted in the literature.

Abstract: En | Text: En | PDF: En

Objective: Clinical and biological correlates of resilience in major depressive disorder are scarce. We aimed to investigate the effect of the Val66Met polymorphism in the BDNF gene on resilience scores in major depressive disorder patients and evaluate the polymorphism’s moderation effect on resilience scores in response to cognitive therapy. Method: A total of 106 major depressive disorder patients were enrolled in this clinical randomized study. The Resilience Scale and the Hamilton Rating Scale for Depression were applied at baseline, post-treatment, and at six months of follow-up. Blood samples were obtained at baseline for molecular analysis. Results: The baseline resilience scores were higher in patients with the Met allele (114.6±17.6) than in those with the Val/Val genotype (104.04±21.05; p = 0.037). Cognitive therapy treatment increased resilience scores (p ≤ 0.001) and decreased depressive symptoms (p ≤ 0.001). In the mixed-effect model, the Val/Val genotype represented a decrease in resilience scores (t218 = -1.98; p = 0.048), and the Val66Met polymorphism interacted with sex to predict an increase in total resilience scores during cognitive treatment (t218 = 2.69; p = 0.008). Conclusion: Our results indicate that cognitive therapy intervention could improve resilience in follow-up, considering that gender and genetic susceptibility are predicted by the Val66Met polymorphism.

ABSTRACT. Anthracnose, which is caused by the fungus Colletotrichum lindemuthianum, is one of the most widespread and important diseases of the common bean (Phaseolus vulgaris L.) in the world. The objective of the present study was to characterize the genetic resistance of the Beija Flor cultivar by inheritance and to conduct allelism tests. The inheritance test was conducted in the F2 population derived from the Beija Flor (resistant) x TU (susceptible) cross inoculated with race 2047 of C. lindemuthianum. Furthermore, allelism tests exhibited a fitted segregation ratio of 15R:1S, thereby indicating the independence of the Beija Flor gene from the following previously characterized genes: Co-1, Co-2, Co-4, Co-42, Co-6, Co-12, Co-14, Co-15, and Co-Pe. Based on the aforementioned results, we are proposing the symbol Co-Bf to designate the new anthracnose resistance gene in the Brazilian Andean common bean cultivar Beija Flor. This cultivar is an important source of resistance to C. lindemuthianum that should provide a valuable contribution to the common bean breeding program for anthracnose resistance.

Resumo A estrutura de assembleias de água doce pode ser influenciada diretamente pela urbanização ou indiretamente por reduções em heterogeneidade ambiental (HA). Para separar os efeitos da urbanização dos da HA, variáveis substitutas a esses processos precisam ser não-correlacionadas. Avaliamos os efeitos do grau de urbanização e HA na estrutura das assembleias de peixes. Amostramos peixes em 45 riachos localizados na área urbana de Cuiabá. Avaliamos os efeitos da urbanização e HA na riqueza rarefeita de espécies de peixes (Srarefeita), contribuição local para a diversidade beta (LCBD) e composição de espécies utilizando modelos lineares e análise de redundância baseada em distância. Nossos índices de urbanização e HA não foram correlacionados. Observamos que tanto a Srarefeita e a LCBD diminuíram com aumentos no grau de urbanização, mas não foram correlacionadas com a HA. Também observamos que as abundâncias de poucas espécies de peixes nativos correlacionaram-se com HA. Serrapinnus microdon, S. calliurus, Hemigrammus tridens e Astyanax lacustris foram mais abundantes em riachos com menor grau de urbanização. A não-nativa Poecilia reticulata foi mais abundante em riachos com maior grau de urbanização. Nossos resultados destacam que a urbanização resulta em impactos negativos nas assembleias de peixes, tais como reduções da diversidade e a dominância de espécies não-nativas.

Abstract The structure of freshwater assemblages may be driven directly by urbanization or indirectly by a reduction in environmental heterogeneity (EH). Disentangling the effects of urbanization and EH requires uncorrelated proxies of each of these factors. We assessed the effects of the degree of urbanization and EH on the structure of fish assemblages. We sampled fish in 45 streams located in the urban area of Cuiabá. We assessed the effects of urbanization and EH on rarefied fish species richness (Srarefied), the local contribution to beta diversity (LCBD), and composition with linear models and distance-based redundancy analysis. Our indexes of urbanization and EH were not correlated. We found that both Srarefied and the LCBD decreased with an increasing degree of urbanization, but were not associated with EH. We also noted that few native fish species abundances were associated with the EH. Serrapinnus microdon, S. calliurus, Hemigrammus tridens, and Astyanax lacustris were abundant in streams with a lower degree of urbanization. The non-native Poecilia reticulata was more abundant in streams with a higher degree of urbanization. Our results highlight that urbanization leads in negative impacts on fish assemblages, such as decreases in diversity and the dominance of non-native species.

This work aims to investigate the energy-related characteristics of apple bagasse, orange bagasse and cashew-apple bagasse to identify their potential as bioenergy feedstocks. For this, a detailed characterization was performed, including proximate analysis, ultimate analysis, atomic molar ratio, heating values, chemical composition, bulk density, bioenergy density, fuel-value-index (FVI), fossil fuel equivalence and potential CO2 retention. Proximate composition revealed moisture, volatile matter, fixed carbon and ash contents in the range of 7.8-9.3%, 67.1-74.2%, 16.2-22.0% and 1.6-5.7%, respectively. Typical values for carbon (44.8-49.9 wt.%), hydrogen (5.5-6.6 wt.%) and oxygen (40.1-44.2 wt.%), with low sulfur (< 0.1 wt.%) and nitrogen (< 2.7 wt.%) contents were found. In regard to bulk density (237.7-554 kg m−3) and bioenergy density (3.93-10.1 GJ m−3), juice processing residues have substantial values when compared with well-known lignocellulosic residues. Recoverable energy potential from the juice processing residues varied from 15.24 to 17.03 MJ kg−1. From FVI analysis, apple bagasse is expected to be more suitable for thermochemical processing. Orange bagasse, on the other hand, has the highest equivalent in fossil fuel volume. Consequently, its use as solid fuel may lead to a decrease in CO2 emissions from reference fuels.

RESUMO: O uso precoce de antimicrobianos tem sido adotado em muitas fazendas para profilaxia das diarreias e doença respiratória em bezerras, no entanto existem controvérsias sobre os beneficios desta prática na saúde desses animais. Esta pesquisa avaliou a influência do uso precoce de antimicrobiano na sanidade e desempenho de bezerras holandesas recém-nascidas. Para tanto foram selecionadas 26 bezerras Holandesas distribuídas de acordo com a aplicação (ATB+) ou não (ATB-) de tulatromicina (2,5mg/Kg) por via subcutânea até 12h de vida. As bezerras foram examinadas por meio de exame clínico geral, escore fecal, escore respiratório e palpação externa da região umbilical, além da matéria seca fecal. A presença de anemias foi determinada pelo eritrograma utilizando sistema automático e além da dosagem de ferro utilizando kit comercial. O diagnóstico etiológico das diarreias foi investigado por meio da técnica de flutuação em solução saturada de sacarose (Cryptosporidium) e multiplex semi-nested RT-PCR (rotavírus/coronavírus). O desempenho das bezerras foi estimado pelo ganho de peso. As bezerras foram avaliadas até doze horas após o nascimento (≤12h); 3-5º (D3-5); 7-9º (D7-9); 13-15º (D13-15); 20-23º (D20-23); e 27-30º dias de vida (D27-30). Não foram encontradas diferenças entre os grupos ATB+ e ATB- em relação à frequência cardíaca, frequência respiratória e temperatura retal. O eritrograma revelou maior frequência de anemias no grupo ATB- (P=0,016) no D3-5. Neste momento também foram observados menores valores de ferro sérico (P=0,051). Foram detectados treze casos de doença respiratória durante o estudo, no entanto não foi possível detectar diferença entre os grupos. A frequência de diarreias (escore fecal 2 e 3) foi alta em ambos os grupos, observando-se pico no D13-15 (ATB+=92,3%; ATB-=92,3%). Não observamos diferenças entre os grupos em relação a frequência de diarreia considerando-se a matéria seca fecal. O agente etiológico predominante nas diarreias foi o Cryptosporidium. O ganho de peso diário foi igual entre grupos, com intensa redução no GPD no D13-15. A administração de tulatromicina na dose profilática (2,5mg/Kg) ao nascimento diminuiu a frequência de anemias e não influenciou no ganho de peso e prevalência de diarreias.

ABSTRACT: The early use of antimicrobial therapy has been introduced in many farms to prevent diarrhea and respiratory disease in young calves; however, there is controversy about whether this practice has a beneficial effect on the health of these animals. This study evaluated the influence of the early use of antimicrobials on the health and performance of neonatal Holstein calves. Twenty-six Holstein calves were screened and divided into two groups, according to the administration (ATB+), or not (ATB-) of tulathromycin (2.5mg/kg, subcutaneously) within the first 12 hours of life. Calves were evaluated by general clinical examination, fecal score, respiratory score, and external palpation of the umbilical region, besides fecal output of dry matter. Anemia was determined by using an automatic system and, also, using a commercial kit for iron dosage. Diarrhea was diagnosed by a centrifuge-flotation technique using a sugar solution (Cryptosporidium) and multiplex semi-nested RT-PCR (rotavirus/coronavirus). The performance of the calves was estimated by Daily Weight Gain (DWG). The young dairy calves were evaluated within 12 hours of birth (≤12h) and at 3-5th (D3-5), 7-9th (D7-9), 13-15th (D13-15), 20-23rd (D20-23), and 27-30th (D27-30) days of life. No difference was noted between the ATB+ and ATB- groups concerning heart rate, respiratory frequency, and rectal temperature. Erythrogram showed a higher frequency of anemia in ATB- group (P=0.016) at the D3-5 check-up; lower values of serum iron were also observed simultaneously (P=0.051). Thirteen cases of respiratory disease were detected during this study; however, no significant difference was observed between the groups in this regard. The frequency of diarrhea (fecal score 2-3) was high in both groups, peaking at D13-D15. No differences were noted between the groups regarding the frequency of diarrhea when considering the dry fecal matter. The predominant etiological agent for diarrhea was Cryptosporidium spp.. The DWG was similar between groups, with maximum weight reduction on D13-15. The administration of tulathromycin in prophylactic dose (2.5mg/kg) at birth decreased the frequency of anemia but did not influence weight gain or the prevalence of diarrhea.
