Using Remote Sensing to Quantify the Joint Effects of Climate and Land Use/Land...
Jardim, Alexandre Maniçoba da Rosa Ferraz; Araújo Júnior, George do Nascimento; Silva, Marcos Vinícius da; Santos, Anderson dosCaatinga biome, located in the Brazilian semi-arid region, is the most populous semi-arid region in the world, causing intensification in land degradation and loss of biodiversity over time. The main objective of this paper is to determine and analyze the changes in land cover and use, over time, on the biophysical parameters in the Caatinga biome in the semi-arid region of Brazil using remote sensing. Landsat-...

Influence of meteorological elements on behavioral responses of gir cows and ef...
Silva, Marcos Vinícius da; Almeida, Gledson Luiz Pontes de; Pandorfi, Héliton; Moraes, Alex Souza; Macêdo, Gleidiana Amélia Pontes de AlmeidaThis study aimed to analyze the principal components of the meteorological variables, physiological and behavioral response of cows subjected to different cooling times and their influence on milk quality, in the dry and rainfall periods, and to establish multiple regression models for milk quality. The data used in the study came from an experiment conducted in the Agreste Region of Pernambuco. The pre-milking...
Exploratory data inference for detecting mastitis in dairy cattle
Silva, Rodes Angelo Batista da; Pandorfi, Héliton; Almeida, Gledson Luiz Pontes de; Silva, Marcos Vinícius daThe aim of this study was to employ the principal component technique to physiological data and environmental thermohygrometric variables correlated with detection of clinical and subclinical mastitis in dairy cattle. A total of 24 lactating Girolando cows with different clinical conditions were selected (healthy, and with clinical or subclinical mastitis). The following physiological variables were recorded: u...
VARIAÇÃO ESPAÇO-TEMPORAL DA TEMPERATURA DO SUBSTRATO EM BANDEJAS DE PRODUÇÃO DE...
Cavalcanti, Sávio Duarte Lopes; Gomes, Nicoly Farias; Pandorfi, Héliton; Almeida, Gledson Luiz Pontes; Montenegro, Abelardo Antônio de AssunçãoA temperatura do substrato nas bandejas é um fator variável no tempo e no espaço, que assume relevante importância nos processos físicos e nas trocas de energia com a atmosfera. Esta grandeza física interfere na germinação, crescimento radicular, absorção de água e nutrientes. Dessa forma, o conhecimento da dinâmica da temperatura do substrato é fundamental para a agricultura. Para tanto, essa pesquisa foi cond...

Dias Batista, Pedro Henrique; Kariny Feitosa, Anny; Pontes de Almeida, Gledson Luiz; Pandorfi, Héliton; de Oliveira Silva, Douglas AlbertoA banana é uma das frutas mais importantes do mundo, tanto no que se refere à produção quanto à comercialização. O objetivo do estudo é analisar economicamente a produção de banana nos municípios de Iguatu e Cariús-CE. Utilizaram-se dados obtidos por meio de questionário aplicado a 20 produtores da região. Partindo da análise da receita mensal total, do custo mensal total, do lucro mensal médio e do investiment...
Monitoring the bovine activity in grazing by an electronic sensing device based...
Batista, Pedro Henrique Dias; Almeida, Gledson Luiz Pontes de; Sarmento, Roger Moura; Pandorfi, Héliton; Melo, Airon Aparecido Silva deThe joint analysis about cattle positioning and activity in pasture associated to soil attributes, become important for making decisions and forage management. In this work, the prototype of an electronic sensing device based on global positioning system (GPS) was developed with the objective of monitoring dairy cattle position in pasture and associating animal preference areas to possible changes for soil pene...
Efficiency of use of supplementary lighting in rearing of dairy calves during m...
Almeida, Gledson; Pandorfi, Héliton; Baptista, Fátima; Guiselini, Cristiane; Fitas da Cruz, Vasco; Almeida, GleidianaThe objective of this study was to evaluate programs of supplementary lighting for calves in individual shelters with different roof materials, as a strategy to stimulate concentrate consumption and the reduction of the milk feeding period and increase financial viability. Twenty seven dairy crossed Holstein × Gir female calves were randomly distributed in individual shelters with three different roofing materi...
