Botswana experiences long, hot summer periods which negatively affect broiler productivity and results in economic losses. To determine these negative effects, two parallel broiler production studies were conducted in the North eastern (NE) and South eastern (SE) regions. In each region, three large scale commercial broiler farms were randomly selected based on similarities in bird management and housing systems. In each farm, one house type (Gable, Hoop and See-saw) was selected for long term flock monitoring (1 to 35 days) over three production cycles. Results showed that the production performance of the broilers in the SE region was superior to that in the NE region, with temperatures on being average higher in the NE than in the SE. The European Production Efficiency Factor (EPEF) was significantly higher ( p <0.05) in the SE (209) than in the NE (174). In the NE region, the broilers reared in the Hoop structure performed significantly better ( p <0.05) than in both the Gable and See-saw structures in regards to feed consumption, average daily gain, and water consumption. In the SE region, only water consumption was significantly higher ( p <0.05) in the Gable structure as compared to the other house structures. At the point of slaughter (35 days), there were significant differences ( p

Cancer is a serious public health problem worldwide. This clinical pathology is associated with the activation/release of several biomolecules, including the Smyd proteins family. In this way, some studies indicate that Smyd3 is associated with cancer cells growth. It is important to mention that some drugs act as Smyd3 inhibitors in the treat some cancers. However, their interaction is very confusing; for this reason, the aim of this research was to evaluate the theoretical interaction of benzenesulfonamide and their derivatives (compounds 2 to 28) using 7o2c protein, novobiocin, BAY-6035, EPZ031686 and BCI-121 drugs as theoretical tools in DockingServer program. The results showed differences in the aminoacid residues involved in the interaction of benzenesulfonamide and their derivatives with 7o2c protein surface compared with novobiocin, BAY-6035, EPZ031686 and BCI-121 drugs. In additions, the inhibition constant (Ki) for benzenesulfonamide derivatives 2, 7, 8, 13, 14, 17, 20, 21, 24 and 28 was very lower compared to benzenesulfonamide, novobiocin, BAY-6035, EPZ031686 and BCI-121. In conclusion, the benzenesulfonamide derivatives 2, 7, 8, 13, 14, 17, 20, 21, 24 and 28 could be a good alternative as Smyd3 inhibitors to decrease cancer cells growth.

Excessive exposure of human to organic contaminants from industrial effluents calls for the implementation of effective pollutants removal techniques. This article investigates the photocatalytic degradation of bromophenol blue dye using Strontium oxide nanoparticles co-doped with Nickel and Zinc. Hydrothermal synthesis produced the nanoparticles, which were subsequently characterized using various analytical techniques. UV/Visible revealed absorption peaks at 294 nm, 306 nm, 311 nm, and 318 nm, while FTIR spectroscopy identified stretching peaks at 416 cm-1, 588 cm-1, and 856 cm-1 for Ni-O and Sr-O bonds. The nanoparticles displayed diameters ranging from 30.50 nm to 36.97 nm. EDX analysis confirmed the elemental composition, with Sr and O comprising of approximately 82.02 %, and Ni and Zn approximately 3.21%. Photocatalytic degradation experiments demonstrated that SrO nanoparticles 85.42% degradation efficiency, while co-doped SrO nanoparticles achieved an impressive 97.97% degradation efficiency. This work highlights the potential co-doped SrO nanoparticles as a promising solution for the efficient removal of organic pollutants from the industrial wastewater, addressing environment contamination concerns.

The acoustic landscape of a place is formed by biophony, anthropophony and geophony. Biophony comprises the sounds produced by living beings, mainly animals during their communications; geophony consists of the sounds of the geophysical environment, like a river, the rain and waterfalls. In this case study, we evaluated the effectiveness of passive bioacoustic monitoring in detecting anthropogenic pollution in an urban park in Belo Horizonte, Brazil. We used the Song Meter recorder model SM2+ from the Wildlife Acoustics, the recorders were configured to receive sounds of up to 20 Hz. Each recorder was fixed in trees 1.5 m above the ground and 2 microphones were used in each of them. The collected data were submitted to the Generalized Linear Model Test (GLMM), which resulted in a strong influence of anthropic noises on the birds' vocalization. Our results demonstrate the effectiveness of the method and point to the need for the development of public policies to mitigate the effects of noise pollution in urban parks.

The connectivity study is essential for the comprehension of various ecological processes, but it is poorly studied in aquatic environments, where hydrological connectivity is understood as the transfer of water, energy, and organisms from one part of the landscape to another. This work aims to analyze the hydrological connectivity present in the territory of the Tietê-Jacaré Hydrographic Basin - SP, through the application of the Hydrological Connectivity Index, to evaluate the dynamic and temporal process of these structures in 2007 and 2017. Geographic Information Systems (GIS) techniques were applied with the application of integration theory to investigate which rivers, wetlands, lakes, dams are connected. From 2007 to 2017, a reduction of 8,686.42 to 8,686.42 km was observed, totaling 208.35 km of the drainage network. There was also a loss of 163.77 km of springs (24.10%) and a reduction in the number of interactions between the hydrological network from 7,214 to 5,303. The updating of the information on the water resources extension complemented by the application of the indices, by expressing the state of landscape configuration, were important tools in the diagnosis of ecosystem conservation, enabling accurate analysis of the elements that compose them. The hydrographic basin showed a reduction in the drainage network in all regions, which consequently resulted in changes in the patterns of hydrological connectivity, reducing the number of connections by almost half. These factors must be analyzed in detail concerning the planning of the hydrographic basin, mainly related to the future of the quantity and quality of water resources.

A família Heliornithidae é composta por uma única espécie, a Picaparra (Heliornis fulica), encontrado principalmente na região neotropical. Apesar de ter uma distribuição ampla, acredita-se que a espécie tenha baixas densidades populacionais. Ela prefere habitats como córregos, rios tranquilos e lagoas de água doce com vegetação ribeirinha proeminente. Sua dieta é composta por insetos aquáticos, larvas, besouros, formigas, aranhas, crustáceos, anfíbios e pequenos peixes. A Picaparra é difícil de ser observado devido ao seu padrão de cor discreto e comportamento secreto. O Parque Natural Municipal de Capanema, no Paraná, foi criado com o objetivo de preservar ecossistemas naturais e permitir pesquisas científicas. A Picaparra foi recentemente avistado nessa área, preenchendo uma lacuna na distribuição geográfica da espécie. A proteção de habitats naturais é crucial para a sobrevivência da Picaparra e outras espécies limícolas.

The objective of this study was to describe the growth curve of Brazilian Creole chickens of the Canela-Preta breed raised in two different rearing systems using non-linear growth models. A total of 400 birds were divided into two groups of 200 animals (of both genders), which were kept in confined or semi-confined systems. The confined birds were housed in an experimental masonry shed and the semi-confined animals were housed in another shed with access to pasture from 29 days of age. Birds were individually weighed every seven days during six months for determination of the growth curves of body weight using 10 non-linear models. The parameters of the models were estimated using the Gauss Newton method. The performance of the models was assessed using mean squared error (MSE), coefficient of determination (R 2 ), percentage of convergence, and residual mean absolute deviation (MAD). With the exception of the Inverse Polynomial, all the other models had R 2 values close to one. Therefore, the best models were chosen based on the lowest MSE and MAD values, with the Richards model ranking first followed by the Von Bertalanffy model. Gender and rearing system effects significantly influenced ( p< 0.05) some parameters of the Richards model. In conclusion, the Richards model was the most adequate to describe the growth of Canela-Preta chickens. Gender and rearing system significantly influenced the growth of the birds. The growth rates observed indicated that management strategies can be performed to increase the production efficiency of Canela-Preta chickens

This study investigated the effects of bamboo vinegar (BV) on production performance, egg quality, antioxidant status, and serum biochemical parameters of laying hens during summer. One hundred twenty 36-week-old Hy-Line Brown laying hens were randomly assigned to 4 groups, with 30 hens per group. The control group was fed a basal diet and 1 mL/kg, 5 mL/kg, and 10 mL/kg BV were added to the basal diet of the 0.1% BV, 0.5% BV and 1.0% BV groups, respectively. The experiment lasted 30 days and showed that the production performance was not significantly affected by the addition of BV (p >0.05). Egg shape index and glutathione peroxidase activity in serum in BV-supplemented groups were significantly increased ( p< 0.05). The total protein and the albumin content in the 0.1% BV, 0.5% BV, and 1.0% BV groups were significantly increased compared to the control group ( p< 0.05). These results suggested that dietary BV could improve the antioxidant capacity and the egg shape index of laying hens in summer.

This study aims to identify relative proportions of beneficial and pathogenic bacteria in the gut of broilers and risk factors that may be contributing to the development of colibacillosis disease in broiler farms of District Kasur, Punjab, Pakistan. For this, 10 healthy and 10 colibacillosis affected broiler farms were surveyed for ileum and blood sample collection along with data regarding farm management, antibiotic use and hygiene practices. Lactobacillus and Escherichia coli number was estimated using Miles and Misra method and colibacillosis was confirmed by Congo red dye assay. Lactobacillus and E. coli were identified biochemically. For risk factors analysis chi-square analysis was performed to find any significant association between the health status of the farm and risk factors. Results showed during disease and healthy conditions Lactobacillus and Escherichia coli counts differ significantly ( p <0.05). E. coli counts (106-108 to 107-109) increased ( p <0.05) about three folds and Lactobacillus counts decrease (106-108 to 105-107) about four folds in disease conditions. Risk factor analysis showed colibacillosis disease was significantly associated ( p <0.05) with non-vaccinated flocks, natural ventilation systems, rodent presence and the lack of outfit disinfection or change by workers when moving between different houses. It is concluded that E. coli and Lactobacillus work antagonistically to each other. However, further research is necessary to determine the exact mechanisms by which E. coli and Lactobacillus influence the development of colibacillosis. While Lactobacillus as probiotic may help with prevention, good hygiene and management practices are still crucial in preventing the spread of disease.

Results showed during disease and healthy conditions Lactobacillus and Escherichia coli counts differ significantly ( p <0.05). E. coli counts (106-108 to 107-109) increased ( p <0.05) about three folds and Lactobacillus counts decrease (106-108 to 105-107) about four folds in disease conditions. Risk factor analysis showed colibacillosis disease was significantly associated ( p <0.05) with non-vaccinated flocks, natural ventilation systems, rodent presence and the lack of outfit disinfection or change by workers when moving between different houses. It is concluded that E. coli and Lactobacillus work antagonistically to each other. However, further research is necessary to determine the exact mechanisms by which E. coli and Lactobacillus influence the development of colibacillosis. While Lactobacillus as probiotic may help with prevention, good hygiene and management practices are still crucial in preventing the spread of disease.","PeriodicalId":9244,"journal":{"name":"Brazilian Journal of Poultry Science","volume":"1 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67656367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
O sprint design é um método aplicado em cinco dias utilizado pelo google venture para gerar novas ideias conectadas à gestão estratégica, inovação, ciência comportamental e design para softwares, marketing, serviços e outras áreas, além de garantir uma busca de soluções mais eficiente, rápida e focada nos desafios. A abrangência de assuntos nos quais o sprint design pode ser aplicado permitiu a escolha de um tema a ser tratado, que é o objetivo desse trabalho: a execução do método em um projeto de arquitetura da informação de um portal web de serviços públicos do município de São Paulo. Neste trabalho éapresentado um ciclo de sprint design aplicado junto a uma equipe de transformação digital de serviços públicos, cidadãos e servidores públicos da cidade de São Paulo para encontrar soluções ao desafio proposto de dificuldade em entender as informações do site em questão. Pelo resultado do método executado no contexto da gestão pública com algumas adaptações, foi possível perceber a eficácia e garantia de entrega de uma solução co-construída entre governo e cidadãos de forma rápida, eficiente, testada e focada nos munícipes. Além disso, tornou-se perceptível que a inclusão de servidores públicos e de cidadãos no processo do sprint design contribuiu para expandir uma cultura de fomento à inovação e construção de políticas públicas da agenda de governo digital junto à sociedade.
