Resumo: The aim of this study was to evaluate the welfare and spatial distribution of noise levels in a swine nursery during the first three weeks of animal’s life. The climatic conditions were evaluated through the dry-bulb temperature (Tdb), relative humidity (RH) and black globe temperature and humidity index (BGHI) and allowed us to observe that the heating system influenced the conditions in the environment, and the use of the air conditioning system did not guarantee animal’s comfort conditions. The analysis on the spatial distribution of noise levels was performed using geostatistics and demonstrated the occurrence of spatial variability inside the facilities. The highest frequencies of noise levels were concentrated between 60 and 70 dB, and the highest noise values were observed near the fans. The mean BGHI values were below the thermal comfort range for piglets in all systems tested.

A avaliação das condições climáticas, realizada através da temperatura de bulbo seco (Tbs), umidade relativa (UR) e índice de temperatura do globo negro e umidade (ITGU), permitiu observar que o tipo de sistema de aquecimento influenciou as condições do ambiente, assim como a utilização do sistema de climatização não garantiu condições de conforto aos leitões. A análise da distribuição espacial dos níveis de ruído, realizada por meio da técnica de geoestatística, possibilitou verificar a ocorrência de variabilidade espacial no interior da instalação. As maiores frequências dos níveis de ruído concentram-se entre 60 e 70 dB. Os valores médios de ITGU situaram-se fora da faixa de conforto térmico para os leitões em todos os sistemas testados.Departamento de Engenharia Agrícola - UFCG2020-04-24T13:13:02Z2020-04-24T13:13:02Z2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfDAMASCENO, F.
