ITU, ITGU, Conforto térmicoResumen
A produção suína contemporânea enfrenta desafios associados ao estresse térmico, uma vez que o melhoramento genético contribui com linhagens apropriadas para a deposição de carne magra, elevando a produção de calor interno dos animais, cuja dissipação de energia é limitada pelo seu sistema de termorregulação precário. Objetivou-se a analisar a integração e complementaridade de índices bioclimáticos aplicados na determinação do conforto térmico dos suínos em diferentes sistemas de produção. A metodologia se baseou em uma revisão sistemática da literatura de artigos científicos publicados entre 2016 a 2026, indexados na base de dados Scopus, utilizando a string de busca (sow OR sows OR swine) AND ("thermal comfort" OR "heat stress") AND (THI OR BGHI) AND housing. Inicialmente foram identificados 135 artigos que, após a aplicação de critérios de inclusão e exclusão embasados no escopo da ambiência e zootecnia de precisão, resultaram em uma amostragem de 24 artigos focados na comparação direta das métricas ambientais. Os resultados obtidos evidenciaram que a determinação do conforto térmico e a tipologia das construções dos galpões são fenômenos indissociáveis. O confronto dos dados demonstrou que o Índice de Temperatura e Umidade (ITU/THI) isolado apresenta pontos cegos diagnósticos por desconsiderar o aporte radiante das coberturas e a velocidade do ar. Em contrapartida, o uso combinado com o Índice de Temperatura de Globo e Umidade (ITGU/BGHI) mitiga essas falhas ao monitorar a via radiante, sendo essencial para orientar o acionamento de sistemas de resfriamento em instalações abertas e refinar os algoritmos de automação em galpões climatizados por pressão negativa. Conclui-se que a abordagem multivariada é indispensável para um diagnóstico microclimático fidedigno, ressaltando-se a necessidade urgente de calibração regional dos limiares matemáticos clássicos para a realidade de baixas latitudes, como o ecossistema equatorial amazônico.
