Especificamente, o tema está relacionado ao estudo referente ao cálculo das exigências nutricionais de energia para mantença de cordeiros da raça Texel. O processo de modelagem consiste em obter um modelo matemático a partir do ajuste de funções aos dados experimentais, podendo assim realizar o cálculo do ponto fixo da função. O experimento foi realizado no Laboratório de Ovinocultura da Universidade Federal de Santa Maria (UFSM). Um dos objetivos da pesquisa era determinar a exigência de Energia Metabolizável para mantença (EMm), que segundo a metodologia empregada pelos pesquisadores, consiste em obter o ponto de equilíbrio da função que relaciona a Produção de Calor (PC) e o Consumo de Energia Metabolizável (CEM). Em termos matemáticos, o objetivo é obter o melhor ajuste de curva para o conjunto de valores observados pelo método dos mínimos quadrados linear e o ponto fixo pelo método de iteração de ponto fixo. O software Visual Cálculo Numérico (VCN) foi usado para validação do modelo proposto, incentivando o uso de novas tecnologias. Além disso, o trabalho busca disponibilizar um aporte teórico e conceitual dos métodos matemáticos usados na modelagem. A motivação deste estudo é levar a matemática aplicada para áreas da ciências agrárias.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de Ciências Naturais e ExatasPrograma de Pós-Graduação em Matemática em Rede NacionalUFSMBrasilMatemáticaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessPonto de equilíbrioPonto fixoModelagemMétodos numéricosEnergia metabolizável para mantençaZootechnyBreak-even pointFixed pointModelingNumerical methodsMetabolizable energy for maintenanceCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICAMétodos matemáticos: uma aplicação nas ciências agráriasMathematical methods: an application in the agrarian sciencesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisBuligon, Lidianehttp://lattes.cnpq.br/4755671184790141Meneghetti, Cinthya Maria Schneiderhttp://lattes.cnpq.br/9380317334360530Kozakevicius, Alice de Jesushttp://lattes.cnpq.br/1143985671114403Szinvelski, Charles Rogério Pavegliohttp://lattes.cnpq.br/2186097538587489http://lattes.cnpq.br/4368489310460992Meira, Juliano Silveira100100000008600320148d6-c002-4117-aee7-5e2ce365022572ddb653-1a46-433c-addf-e14769f0126de3b128d2-6076-45d3-a047-71358a16177d96624bf1-e10c-4201-9ae2-26a03a6b45a608ad981f-bd66-400c-9984-df21e5ed345dreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGMRN_2018_MEIRA_JULIANO.pdfDIS_PPGMRN_2018_MEIRA_JULIANO.pdfDissertação de Mestradoapplication/pdf1118706http://repositorio.ufsm.br/bitstream/1/16285/1/DIS_PPGMRN_2018_MEIRA_JULIANO.pdfa95db1e50154a05c945f242eba36b158MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
