Resumo: | The aim of this study was to compare three methods of processing thermographic images for the evaluation of carpal temperature in healthy calves. Additionally, we sought to evaluate the thermal symmetry between the contralateral carpi of these calves. Thermographic images were obtained from both carpi of eight healthy calves aged between 20 and 45 days with a mean weight of 38.65 ± 2.27 kg. Using GRAYESS® IRT Analyzer 7 software, the total temperature (Ttot), region-of-interest temperature (Troi), and maximum mean temperature (Tmax) were determined. There was no difference between the temperatures obtained by the Ttot and Troi methods. Tmax showed higher temperatures (p < 0.01) than the other methods. The three image processing methods showed high and significant positive correlations for the temperature of the right and left carpi of healthy calves. Tmax presented a higher correlation coefficient (r = 0.99) than the two other methods, which suggests a greater sensitivity for identifying thermal variations among the contralateral carpi. The 99% confidence interval for the difference between the temperatures of the right and left carpi (Δr-l) was between 0.03 and 0.26°C; thus, a temperature variation within that range does not refer to pathologic processes.Key words: cattle; joint; thermal symmetry; thermography |

Adicionalmente, buscou-se avaliar a simetria térmica entre os carpos contralaterais desses bezerros. Foram obtidas imagens termográficas de ambos os carpos de oito bezerros, hígidos, com idade entre 20 e 45 dias e peso médio de 38,65 ± 2,27 kg. As imagens foram analisadas por meio do software GRAYESS® IRT Analyzer 7, que possibilitou a obtenção da temperatura total (Ttot), temperatura da região de interesse (Troi) e temperatura máxima média (Tmax). Não houve diferença entre as temperaturas obtidas pelos métodos Ttot e Troi. O Tmax mostrou temperaturas mais elevadas (p < 0,01) em comparação aos demais métodos. Os três métodos de processamento de imagens apresentaram correlações elevadas e significativas para a temperatura dos carpos direito e esquerdo de bezerros saudáveis, entretanto, o Tmax apresentou maior coeficiente de correlação (r = 0,99), o que sugere maior sensibilidade para identificação de variações térmicas entre os carpos contralaterais. O intervalo de confiança de 99% para a diferença de temperaturas entre os carpos direito e esquerdo (Δd-e) foi de 0,03 a 0,26ºC, o que indica que a variação de temperatura dentro desse intervalo não remete a alteração patológica.Palavras-chave: articulação; bovino; simetria térmica; termografiaUniversidade Federal de Goiás2022-04-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://revistas.ufg.br/vet/article/view/70559Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 23 (2022): Continuous publicationCiência Animal Brasileira / Brazilian Animal Science; v. 23 (2022): Publicação contínua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporenghttps://revistas.ufg.br/vet/article/view/70559/38230https://revistas.ufg.br/vet/article/view/70559/38334https://revistas.ufg.br/vet/article/view/70559/38231https://revistas.ufg.br/vet/article/view/70559/38335Copyright (c) 2022 Ciência Animal Brasileira / Brazilian Animal Sciencehttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCordeiro Borges, Pedro AugustoSilva, Danilo ConradoSilva, Nivan Antônio Alves da Lima, Valesca Henrique Bastos Queiroz, Paulo José Borges, Naida CristinaSilva, Luiz Antônio Franco da 2023-03-23T18:43:54Zoai:ojs.revistas.ufg.br:article/70559Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:28.859191Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
