ABSTRACT The objective of this work was to evaluate the agro-bioeconomic feasibility of immature cowpea and beet cultivar combinations in intercropping systems in a semi-arid environment. Experiments were carried out in two cropping years using a randomized block design with four replicates. The treatments consisted of four cowpea cultivars (‘BRS Tumucumaque,’ ‘BRS Cauamé,’ ‘BRS Guariba,’ and ‘BRS Itaim’) and two beet cultivars (‘Early Wonder’ and ‘Fortuna’). In each block of the experiments, plots in monocropping of the cultivars were sown as additional treatments to obtain the following agronomic and competition indexes and economic indicators: land equivalent ratio (LER), area time equivalent ratio (ATER), land use efficiency (LUE), beet equivalent production (BEP), competitive ratio (CR), crop aggressivity (A), gross income (GI), net income (NI), rate of return (RR), and corrected monetary advantage (CMA). The highest agro-bioeconomic efficiency of the tested intercropping systems was achieved in the combination of cowpea cultivar BRS Guariba and beet cultivar Fortuna. Beet behaved as the dominant crop, and cowpea as the dominated crop in all evaluated intercropping systems. The indexes and indicators demonstrated the complementarity and sustainability of the combination of cowpea cultivar BRS Guariba with beet cultivar Fortuna.

RESUMO O objetivo deste trabalho foi avaliar a viabilidade agrobioeconômica de combinações de cultivares de feijão-caupi imaturo e de beterraba em sistemas consorciados em ambiente semiárido. Os experimentos foram conduzidos em dois anos agrícolas, em delineamento de blocos casualizados com quatro repetições. Os tratamentos consistiram da combinação de quatro cultivares de feijão-caupi (‘BRS Tumucumaque,’ ‘BRS Cauamé,’ ‘BRS Guariba’ e ‘BRS Itaim’) e duas cultivares de beterraba (‘Early Wonder’ e ‘Fortuna’). Em cada bloco dos experimentos, parcelas em monocultivo das cultivares foram semeadas como tratamentos adicionais para obtenção dos seguintes índices agronômicos e de competição e indicadores econômicos: razão equivalente de terra (RET), razão equivalente de área no tempo (REAT), eficiência de uso da terra (EUT), produção equivalente de beterraba (PEB), razão competitiva (RC), indice de superação das culturas (ISC), renda bruta (RB), renda líquida (RL), taxa de retorno (TR) e vantagem monetária corrigida (VMC). A mais alta eficiência agrobioeconômica dos sistemas consorciados testados foi alcançada na combinação da cultivar de feijão-caupi BRS Guariba com a cultivar de beterraba Fortuna. A beterraba se comportou como a cultura dominante e o feijão-caupi como a cultura dominada em todos os consórcios avaliados. Os índices e indicadores determinados demonstraram a complementaridade e sustentabilidade da combinação da cultivar de feijão-caupi BRS Guariba com a cultivar de beterraba Fortuna.

ABSTRACT Tomato genotypes ( Solanum spp.) have genetic variability of most desirable features, such as resistance to biotic and abiotic stresses. However, incompatibility of crosses of wild genotypes with domesticated tomatoes, or even between wild genotypes, hinders the breeding process. Thus, knowledge of the reproductive biology of genotypes and conditions is necessary to maximize the success of artificial crossings. This study evaluated the compatibility of self-pollination, intra- and interspecific controlled crosses, stigma receptivity, and pollen viability in tomato genotypes. We used two commercial genotypes S. lycopersicum (‘RVTM08’ and ‘Redenção’) and seven accessions of wild tomato genotypes (‘AF 26970’, ‘LA-1401’, ‘AF 19684’, ‘LA-1967’, ‘PI-127826’, ‘PI-134417’, and ‘LA-716’). We evaluated all crosses and their reciprocals, besides the self-pollinations. The variables evaluated were fruit index (FI), number of seeds per fruit (SN), and seed germination percentage (GP). Stigma receptivity and grains’ pollen viability index (PVI) were also assessed. The results showed that ‘LA-1967’ was self-incompatible, had a low PVI, and generated fruit without seeds in most crosses. As female parents, ‘RVTM08’, ‘Redenção’, ‘AF 26970’, ‘LA-1401’, and ‘AF 19684’ showed higher FI and SN. There was a wide diversity of reproductive characteristics between the genotypes and crosses that did not influence GP. Compatibility of crosses in tomatoes is determined by the female parent choice and can be affected by stigma receptivity and the PVI.

Abstract The selection of parents to originate promising base populations, as well as the knowledge of the gene effects controlling agronomic traits by means of diallel, are useful to drive genetic gains in Brazilian tropical wheat breeding programs. The goals of this study were to select tropical wheat parents with a high frequency of favorable alleles and segregating populations with high potential to originate superior progenies through partial diallel analysis. Thus, 14 parents were divided in two groups and crossed in a 7 × 7 partial diallel scheme to originate 49 F1 combinations. After obtaining F2 generation, the populations and the parents were evaluated in the field in the summer of 2021. Days for heading, plant height, rust and yellow spot resistance, and grain yield were evaluated. The data were subjected to partial diallel analysis. There were significant effects of general combining ability for all traits. The specific combining ability effect was significant for days for heading and plant height. The additive gene effects were predominant over the non-additive ones. The parents with the highest frequency of favorable alleles for the traits evaluated were selected in each group. Four populations with high genetic potential to originate superior progenies were selected.

ABSTRACT The Apodi-Mossoró River Basin is important for the west region of the state of Rio Grande do Norte (RN), Brazil. The rapid increase in population and consequent need for space has resulted in anthropogenic actions, such as the segmentation of the river course within the municipality of Mossoró, RN. The objective of this study was to assess the effects of this segmentation on soils in alluvial environments. Soil collection points were defined in natural and anthropized areas in the Mossoró urban segment; soil profiles were described and collected; and samples of the soil 0-10 and 10-20 cm were collected. The samples were subjected to physical and chemical analyses to determine granulometry, density, aggregates, pH in water, available phosphorus (P), exchangeable bases, potential acidity, total organic carbon, nitrogen, and micronutrients (Cu and Zn). Maps of location and land use and cover were developed. The soil found in the natural area was classified as Neossolo Fluvico Psamitico eutrico, presenting typical physical and chemical characteristics of this soil class, with variable texture and P contents along the soil profile. The soil in the anthropized area was classified as Planossolo Haplico Carbonatico vertissolico, with Ap Horizon presenting a sandy loam texture, since it is a horizon formed due to anthropogenic activity in the environment. All horizons and profiles presented high pH. The evaluated areas formed different groups regarding soil physical and chemical attributes, with overlapping points that can be explained by anthropogenic actions, even in the environment considered natural.

RESUMO A bacia hidrográfica do Rio Apodi-Mossoró é de grande importância para a região Oeste do Estado do Rio Grande do Norte. Com o aumento acelerado da população e a consequente necessidade de espaço geográfico, ações antrópicas como a tricotomização foram necessárias no curso do rio do município de Mossoró/RN. O presente trabalho objetiva compreender os efeitos da tricotomização em solos no ambiente aluvial. Foram definidos pontos de coleta nas áreas natural e antropizada no trecho urbano de Mossoró, descritos e coletados perfis de solo, além da coleta de amostras de solo nas profundidades de 0 - 0,10 m e 0,10 - 0,20 m. Foram realizadas análises físicas e químicas nas amostras, consistindo em: granulometria, densidade do solo, agregados, pH em água, P disponível, bases trocáveis, acidez potencial, carbono orgânico total (COT), nitrogênio (N) e micronutrientes (Cu e Zn). Também foram confeccionados mapas de localização, uso e ocupação dos solos. O solo observado na área natural foi classificado como Neossolo Flúvico Psamítico êutrico, apresentando características físicas e químicas típicas da classe de solo, como textura e teores de P variáveis ao longo do perfil. Na área antropizada, o solo foi classificado como Planossolo Háplico Carbonático vertissólico, com horizonte Ap apresentando textura franco arenosa por se tratar de um horizonte decorrente da atividade antrópica no ambiente. Todos os horizontes e perfis apresentaram pH elevados. As áreas formam grupos distintos em relação aos atributos físicos e químicos, com pontos de sobreposição que podem ser justificados pela atuação do homem mesmo no ambiente considerado natural.

RESUMO O objetivo foi avaliar a divergência genética entre acessos de espécies silvestres e híbridos interespecíficos F1 de tomateiro. Caracterizou-se seis acessos silvestres (Solanum pimpinellifolium ‘AF 26970’, S. galapagense ‘LA-1401’, S. peruvianum ‘AF 19684’, S. habrochaites var. hirsutum ‘PI-127826’, S. habrochaites var. glabratum ‘PI-134417’ e S. pennellii ‘LA-716’), a cultivar comercial Redenção e os respectivos híbridos interespecíficos F1: ‘Redenção’ x ‘AF 26970’, ‘Redenção’ x ‘LA-1401’, ‘Redenção’ x ‘AF 19684’, ‘Redenção’ x ‘PI-127826’, ‘Redenção’ x ‘PI-134417’ e ‘Redenção’ x ‘LA-716’. Foram avaliados 35 caracteres quantitativos, sendo 29 morfoagronômicos e seis fisiológicos. Realizou-se análises de componentes principais (ACP). Utilizou-se os métodos de otimização de Tocher, baseado na distância de Mahalanobis e a dispersão gráfica das variáveis canônicas, que seguiram a mesma tendência de agrupamento dos genótipos, formando três grupos distintos. As ACP permitiram observar algumas divergências genéticas não observadas pelos demais métodos. Ocorreu alta divergência entre os acessos das espécies e híbridos interespecíficos. A cultivar Redenção teve a maior dissimilaridade genética e os híbridos interespecíficos de S. lycopersicum com acessos silvestres, apresentaram maior similaridade morfoagronômica e fisiológica com os genitores silvestres.

ABSTRACT The objective of this study was to evaluate the genetic divergence among accessions of wild tomato species and interspecific F1 hybrids. Six wild accessions were characterized (Solanum pimpinellifolium ‘AF 26970’, S. galapagense ‘LA-1401’, S. peruvianum ‘AF 19684’, S. habrochaites var. hirsutum ‘PI-127826’, S. habrochaites var. glabratum ‘PI-134417’, and S. pennellii ‘LA-716’), the commercial cultivar Redenção, and the respective interspecific F1 hybrids: ‘Redenção’ x ‘AF 26970’, ‘Redenção’ x ‘LA-1401’, ‘Redenção’ x ‘AF 19684’, ‘Redenção’ x ‘PI-127826’, ‘Redenção’ x ‘PI-134417’, and ‘Redenção’ x ‘LA-716’. Thirty-five quantitative traits were evaluated, encompassing 29 morphoagronomic and six physiological characteristics. Principal component analysis (PCA) was performed. Tocher’s optimization method was used based on the Mahalanobis distance and the graphic dispersion of canonical variables, which followed the same trend of genotype clustering, forming three distinct groups. The PCA indicated some genetic divergences not shown by the other methods. A high divergence was observed among the species accessions and interspecific hybrids. The cultivar Redenção had the greatest genetic dissimilarity, and the interspecific hybrids of S. lycopersicum with wild accessions showed the greatest morphoagronomic and physiological similarity with the wild parents.

Abstract Samanea tubulosa Benth. it has been widely used in traditional medicine to treat inflammatory processes. The present study aimed to investigate the antinociceptive effect and mechanism of action of the fractions obtained from the Samanea tubulosa pods in mice. The antinociceptive activity was evaluated in formalin, capsaicin and glutamate tests and the. The possible mechanisms of action involved in the antinociceptive effect of the hexane and ethyl acetate fraction in the opioid system, also the the K + ATP channels and the L-arigine pathways of nitric oxide were evaluated. The chemical characterization analysis revealed in the hexane fraction the presence of triterpenes such as lupenone and lupeol. In the glutamate test, the hexane and ethyl acetate fractions showed antinociceptive activity at the dose of 12.5 and 25 mg kg-1. The antinociception produced by the hexane and ethyl acetate fractions was significantly reversed by naloxone, indicating that the fractions act through the opioid pathway. Antinociceptive response of the ethyl acetate fraction was blocked by glibenclamide, indicating that this fraction acts via the K + ATP channels activation. It is concluded that the fractions under study exert antinociceptive activity possibly related to the opioid route and through K+ ATP channels activation.

Abstract The main objective of this study is to propose different probabilistic models for adjusting the trend component, since it significantly influences the quality of the spatio-temporal interpolation of rainfalls. We used the monthly total precipitation data of the São Francisco River Basin (SFRB) for the period of 31 years, 1989–2019. The SFRB occupies 8% of the whole Brazilian territory, mostly located in the Northeast Brazilian region. For the trend component, we propose the fitted GAMLSS models by comparing different probability distribution families, which in most cases include the characteristics of these data. The results indicate the existence of a spatio-temporal pattern of the residues obtained from the adjustment of the trend with zero adjusted Gamma distribution for the accumulated monthly precipitation. The adjustment revealed a spatial dependence of up to 873 km between the pluviometric stations and temporal autocorrelation of approximately 1.6 months. The methodology used in this study enabled us to create rainfall maps, interpolating unobserved locations in differences years. The projection of these maps to the SFRB is considered extremely important for planning and implementing activities related to water resources across the river basin.

ABSTRACT Whiteflies (Bemisia tabaci) are a serious threat to tomato (Solanum lycopersicum) yield and production since all varieties are highly susceptible to this insect. The wild tomato Solanum pennellii shows resistance towards whiteflies infestation due the high contents of acylsugars presents in its leaflets, which is not observed in S. lycopersicum. Thus, plants from the F2BC2 population derived from the cross between the cultivar S. lycopersicum ‘Redenção’ and S. pennellii (accession LA-716) were selected for acylsugars levels and evaluated for resistance to whitefly and fumagine, a saprophyte fungus from genus Capnodium (sooty mold) that grows on leaves using whiteflies excretion. Biological behavior of B. tabaci was significantly influenced by the levels of acylsugars on the leaflets of the different genotypes. Solanum pennellii and the genotypes with higher acylsugars contents exhibited the lowest whitefly oviposition preference, number of nymphs, exuviae and adult survival. Also, the percentage of leaf coverage with fumagine was significantly reduced on leaves of the S. pennellii and the genotypes with higher acylsugars. Thus, it confirms that the use of S. pennellii LA-716 enabled the introgression of genes to increase the degrees of resistance in the F2BC2 genotypes. Finally, the results presented suggest that the genotypes RVTA-2010-31-177pl#39, RVTA-2010-31-319pl#214 and RVTA-2010-83-347pl#257 can be used as potential sources of genes for resistance to B. tabaci in tomato breeding programs.

Abstract: En

Background: Sacubitril/valsartan has proven its efficacy to reduce cardiovascular mortality, all-cause mortality and sudden death in heart failure with reduced ejection fraction (HFrEF). Thus, it becomes important to evaluate the safety profile of the medication in clinical practice. Objectives: This study aimed to assess safety outcomes on the use of sacubitril/valsartan in patients with HFrEF attended in a Brazilian specialized service. Methods: Prospective observational study that included patients with HFrEF from a specialized ambulatory service, in functional class II-IV, initiated on sacubitril/valsartan as per clinical indication, with a four-month follow-up. Primary outcomes were the occurrence of symptomatic arterial hypotension, hyperkalemia and reduction of renal function. Serum potassium values, blood pressure and creatinine clearance were analyzed at inclusion and at the end of follow-up. A 5% significance level was considered for comparisons. Results: Twenty-six patients were analyzed, 57.7% male, mean age 57.8 ± 10 years, average left ventricle ejection fraction 29.9 ± 7.7%. Symptomatic hypotension occurred in 53.8%, hyperkalemia in 19.2% and reduction of renal function in 6.7%. There was significant difference from initial to final systolic (122 ± 24mmHg versus 109 ± 15mmHg; p=0.024) and diastolic (76 ± 18mmHg versus 66 ± 12mmHg; p=0.022) blood pressure, but no difference in serum potassium (4.8 ± 0.4mEq/L versus 5.0 ± 0.3mEq/L; p=0.07) and creatinine clearance (65 ± 23mL/min/1.73m² versus 66 ± 29mL/min/1.73m²; p=0.89). Conclusions: Symptomatic hypotension was the most frequent side-effect of sacubitril/valsartan. Reduction of blood pressure was observed at the end of follow-up, but no reduction of renal function or significant increase of serum potassium.

Resumo O presente artigo examina o apoio da população brasileira a posições autoritárias e, de forma ampla, dialoga com as preocupações com os recentes rompimentos democráticos e o fortalecimento de posições antidemocráticas após 30 anos da Constituição Federal. Para tanto, foi realizado um levantamento com uma amostra representativa da população adulta a partir dos 16 anos. Foram entrevistadas 2.087 pessoas que responderam a uma versão de 17 itens da escala de autoritarismo de Adorno (Escala F). Os resultados indicam uma forte adesão às posições autoritárias em todos os estratos sociais, mas ainda mais intensas para segmentos sociais historicamente marginalizados. O medo da violência, que tem sido eficazmente explorado pelos porta-vozes da extrema direita política para o reforço do pânico moral, pode ter sido o propulsor das tendências autoritárias.

Abstract This article examines support to authoritarian positions from Brazilian population and dialogues with concerns about recent democratic disruptions and strengthening of antidemocratic positions post-30 years of the Federal Constitution. For this purpose, a survey was conducted with a representative sample of the adult population from the age of 16 years. 2,087 people interviewees answered a version of 17 items of the Adorno's authoritarianism scale (F Scale). The results indicate a strong adherence to authoritarian positions in all layers of society but even more intense for historically marginalized social segments. The fear of violence, which has been effectively exploited by the spokesmen of the extreme right-wing politician's to reinforce moral panic, may have been the propeller of authoritarian tendencies.

ABSTRACT Stem conicity and the sawing pattern, besides the presence of hollows and sapwood, are among the principal factors that are responsible for the low yield of lumber from harvested wood in the Amazon. Therefore, the objective of this study was to analyze of logs and stem conicity, and its effect on yield of sawn wood from the species Handroanthus impetiginosus (Mart. ex DC.) Mattos, Lecythis lurida (Miers) S. A. Mori, Manilkara huberi (Ducke) Chevalier, Astronium lecointei Ducke and Couratari sp., which are currently the most important commercial species in the study area. The data used were obtained from six production units in the Tapajós National Forest, Pará. The variables analyzed were conicity (obtained as a function of the difference between diameters at the base and top) between logs, DBH classes (diameter at breast height) and species, as well as yield (estimated using the Software MaxiTora) between logs and species. The majority of the species showed differences in conicity between logs, with the first log being the most conic, which was directly reflected by the lower yield for this log. There was a tendency of increase in conicity in the larger DBH classes, and differences in conicity and yield between species. The estimated yields were superior to the percent yields observed for Amazonian species in studies done using samples with similar characteristics. Therefore, it was concluded that conicity can vary between species, logs, and DBH classes, and is a characteristic that directly effects the yield of lumber. Furthermore, the incorporation of cutting templates represents an alternative for maximizing lumber yield.

RESUMO O carcinoma de células escamosas é uma neoplasia maligna que afeta as estruturas e os tecidos da cavidade oral. Interleucinas (IL) sintetizadas a partir de um tumor modulam uma cascata de reações que poderá influenciar o prognóstico da doença. Objetiva-se investigar na literatura se as interleucinas são mediadores que influenciam negativamente ou positivamente o prognóstico de pacientes com carcinoma de células escamosas intraoral. Um estudo de revisão sistemática foi realizado segundo as instruções do Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). As bases de dados PubMed (incluindo MedLine), Scopus, Web of Science, SciELO e Latin American and Caribbean Health Sciences (LILACS) foram utilizadas como fontes de estudo primárias; OpenGrey e OpenThesis, utilizadas para pesquisar a "literatura cinzenta". A busca realizada em sete bases de dados gerais resultou em um conjunto de 858 estudos, enquanto a realizada em duas bases de dados para literatura cinza, em 82 estudos, totalizando 940 pesquisas. Destas, 15 foram selecionadas para a presente revisão sistemática (oito estudos apresentaram baixo risco de viés; quatro, moderado risco de viés; e três, alto risco de viés). Apesar de poderem atuar nas vias de resposta imune antitumoral, as IL avaliadas nesta revisão (IL-4, IL-6, IL-8, IL-10, IL-12 e IL-13) tendem a apresentar uma resposta associada à intensificação do processo de carcinogênese e ao prognóstico desfavorável em pacientes portadores do carcinoma de células escamosas intraoral.

ABSTRACT Squamous cell carcinoma is a malignant neoplasm that affects the structures and tissues of the oral cavity. Interleukins (IL) synthesized from a tumor modulate a cascade reaction that may influence the prognosis of the disease. We aim to investigate in the literature whether interleukins are mediators that negatively or positively influence the prognosis of patients with oral squamous cell carcinoma. A systematic review study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) instructions. PubMed (including MedLine), Scopus, Web of Science, SciELO and Latin American and Caribbean Health Sciences (LILACS) databases were used as the primary sources for the study; OpenGrey and OpenThesis were used to search for "gray literature". The search conducted in seven general databases resulted in a set of 858 studies, while the search conducted in two databases for gray literature resulted in 82 studies, totaling 940 studies. From these, 15 studies were selected for this systematic review (eight studies presented low bias risk; four studies presented moderate bias risk; and three studies presented high risk of bias). Although they may act on the anti-tumor immune response pathways, the IL evaluated in the present systematic review (IL-4, IL-6, IL-8, IL-10, IL-12 and IL-13) tend to present a response associated with the intensification of carcinogenesis and poor prognosis in patients with oral squamous cell carcinoma.

Entre ellas, 15 fueron elegidas para la presente revisión sistemática (ocho estudios presentaron bajo riesgo de sesgo; cuatro, riesgo moderado; tres, riesgo alto). A pesar de poder actuar en vías de respuesta inmune antitumoral, las IL evaluadas en esta revisión (IL-4, IL-6, IL-8, IL-10, IL-12, y IL-13) suelen presentar una respuesta asociada a la intensificación del proceso de carcinogénesis y al pronóstico desfavorable en pacientes portadores de carcinoma oral de células escamosas.

Mimosa bimucronata é uma espécie vegetal que pode ser utilizada em programas de reflorestamento, sendo necessários estudos iniciais para a produção de mudas. Devido à importância desta espécie e à escassez de informações sobre a germinação das sementes, esta trabalho teve por objetivo avaliar i) as características biométricas das sementes por análise multivariada, ii) o efeito de pré-tratamentos de sementes na germinação e iii) caracterizar morfologicamente os diferentes estágios de germinação e de plântula. Foram analisadas a biometria e massa das sementes e oito tratamentos pré-tratamentos: testemunha; ácido sulfúrico (98%) durante dois, cinco e 10 min; água quente a 70 e 80 °C durante 2 min; escarificação mecânica e água destilada durante 24 h. Foram avaliados os diferentes estágios de desenvolvimento da semente até à formação de plântula. As sementes foram expostas a dois ambientes - laboratório e viveiro telado. Foram avaliados a percentagem de germinação e emergência; índice de velocidade de germinação e emergência; e tempo médio de germinação e emergência. De acordo com a análise multivariada, as sementes foram classificadas em três grupos, sendo as classes II e III as mais indicadas para produção de mudas. A germinação com ácido sulfúrico e lixa foram as mais indicadas. A espécie apresenta 10 estágios de desenvolvimento.

Mimosa bimucronata is a plant species that can be used in reforestation programs, and initial studies for the production of seedlings are needed. Due to the importance of this plant species and the scarcity of information on seed germination, this research was carried out with the objective of evaluate i) the biometric characteristics of the seeds by multivariate analysis, ii) the effect of seed pretreatment on germination, and iii) to characterize morphologically the different stages of germination and seedling. The biometry and seed mass and eight pre-germination treatments were analyzed: control; sulfuric acid (98%) for two; five and 10 min; hot water at 70 to 80 °C for 2 min; mechanical scarification and distilled water for 24 h. The different stages of seed development were evaluated until seedling formation. The seeds were exposed to two environments - laboratory and greenhouse. The percentage of germination and emergence were evaluated; germination and emergence speed index; and average time of germination and emergence. According to the multivariate analysis, the seeds were classified into three groups, with classes II and III being the most suitable for seedling production. Germination with sulfuric acid and sandpaper were the most indicated. The species presents 10 stages of development.

Abstract: En | Text: En | PDF: En

ABSTRACT The objective of this work was to evaluate the thermal environment inside conventional cages for laying hens, with and without the use of protective screens. This research was conducted in two conventional cages (open cage), where each cage had half of its area surrounded by high density polyethylene mesh (HDPE) with a diameter of 2.0 cm, and the other half was kept fully open. Hyline W-36 and Dekalb Brown laying hens were housed in these cages. The wind speed, dry bulb temperature (tdb), black globe temperature, humidity index (BGHI), and enthalpy (H) were analyzed. The results indicate that the use of the screen reduced the wind speed inside the cage by 0.22 m s−1. The presence of the screen affected tdb, BGHI, and H in some of the evaluated periods evaluated, making these values higher than those of the treatment without screen. However, the obtained values are within or below the thermal comfort range for laying birds. Therefore, the use of HDPE screen in the cages altered their internal environment. However, it is not enough to hinder the thermal comfort of the housed animals.
