Resumo: | The aim of this work was to evaluate the potential for substitution of traditional methodology for assessing the ingestive behavior of cattle grazing, visual observation, by the use of an electronic recorder provided with an accelerometer. For this purpose, filming, visual monitoring and use of recorder were carried out to identify acceleration patterns for cattle grazing and rumination activities, which made it possible to compare images with graphics generated by the equipment, resulting in the identification of potential for graphic interpretation surpassing the ability for visual observation. Then, an algorithm was evaluated to automate the readings of graphs, qualifying and quantifying time of grazing, rumination and other activities. To conclude the study, comparisons of methodologies (visual observation, graphs interpretation and algorithm versions) were carried out through simple linear regression analysis, seeking the level of correlation between methodologies and the potential for substitution. It was observed that correlations between methodologies were more than 90%, and accuracy of data collected by recorder able to monitor ingestive behavior of cattle grazing using equipment provided with an accelerometer. New tests to develop the algorithm can make this tool even more accurate and able to compute finer data on ingestive behavior such as number of meals, bit rate, rumination rate, among others. |

Para isso foram realizadas filmagens, monitoramento visual e utilização do registrador na identificação de padrões de aceleração para as atividades de pastejo e ruminação de bovinos, o que possibilitou a comparação das imagens com gráficos gerados pelo equipamento, resultando na identificação do potencial de interpretação gráfica superando a capacidade de observação visual. Na sequência, foi avaliado um algoritmo para automatização das leituras dos gráficos, qualificando e quantificando o tempo de atividades de pastejo, ruminação e ócio. Para concluir o estudo, foram realizadas comparações das metodologias (observação visual, interpretação dos gráficos e versões do algoritmo) através de uma análise de regressão linear simples, buscando o nível de correlação entre as metodologias e o potencial de substituição. Foi observado que as correlações entre as metodologias passaram de 90%, além da precisão dos dados coletados pelo registrador, o que remete a capacidade de monitorar o comportamento ingestivo de bovinos em pastejo com o uso do equipamento provido de acelerômetro. Novos testes de desenvolvimento do algoritmo podem tornar essa ferramenta ainda mais precisa e capaz de computar dados mais afinados do comportamento ingestivo como número de refeições, taxa de bocado, taxa de ruminação, entre outros.porUniversidade Federal de Santa MariaCentro de Ciências RuraisPrograma de Pós-Graduação em ZootecniaUFSMBrasilZootecniaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessInteligência artificialMonitoramentoPecuáriaTecnologiaArtificial intelligenceMonitoringLivestockTechnologyCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAAvaliação do uso de acelerômetro na observação do comportamento ingestivo de bovinos em pastejoEvaluation of accelerometer in observing the ingestive behavior of grazing cattleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisQuadros, Fernando Luiz Ferreira dehttp://lattes.cnpq.br/9202266292366562Bremm, CarolinaXXXXXXXXXXXXXXXTrindade, José Pedro Pereira daXXXXXXXXXXXXXXXXXXOliveira, Leandro Bitencourt deXXXXXXXXXXXXXXXPötter, LucianaXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXCasanova, Pedro Trindade50040000000260087f7a696-584d-4ee4-ad83-13fd04320556fc832e3c-51a8-48f8-8fc6-7a8c271cb7aec8e49eaf-bfd8-4fa5-a2d7-4d634981e0487c6a9867-adbd-4673-83f3-c5f0f6fff030a9ddb525-1508-47b5-88ae-957b8e637481ca1383e0-88bf-480e-9a99-a339d97da1d1reponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMCC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

The aim of this work was to evaluate the potential for substitution of traditional methodology for assessing the ingestive behavior of cattle grazing, visual observation, by the use of an electronic recorder provided with an accelerometer. For this purpose, filming, visual monitoring and use of recorder were carried out to identify acceleration patterns for cattle grazing and rumination activities, which made it possible to compare images with graphics generated by the equipment, resulting in the identification of potential for graphic interpretation surpassing the ability for visual observation. Then, an algorithm was evaluated to automate the readings of graphs, qualifying and quantifying time of grazing, rumination and other activities. To conclude the study, comparisons of methodologies (visual observation, graphs interpretation and algorithm versions) were carried out through simple linear regression analysis, seeking the level of correlation between methodologies and the potential for substitution. It was observed that correlations between methodologies were more than 90%, and accuracy of data collected by recorder able to monitor ingestive behavior of cattle grazing using equipment provided with an accelerometer. New tests to develop the algorithm can make this tool even more accurate and able to compute finer data on ingestive behavior such as number of meals, bit rate, rumination rate, among others. |
