Avaliação de diferentes materiais de coberturas para criação de codornas em sistema alternativo.

Abstract

The objective of this research is to evaluate the environmental variables, bioclimatic indices and water temperature in six installations for raising quails in an alternative system in the Brazilian semi-arid region, using ceramic tiles (TC), fiber cement (TF) to cover the installations. , white painted ceramic (TCPB), white painted fiber cement (TFPB), geotint ceramic (TCPG) and geopaint fiber cement (TFPG), each installation measuring an average of 9 m2, surrounded with painter's canvas and 3 m2 of covered area. The climatic variables had a significant effect for the type of roof as well as for the times of day (P<0.05), considering the interaction between roof type and times of day only the internal water temperature variables (P=0.0040) and internal wind speed (P=0.0408) had a significant effect. The internal CTR did not present a significant difference (P=0.9877) depending on the roofs, while the external CTR presented a significant difference (P<.0001) between the studied times. All indices showed a significant difference depending on the type of coverage, with the exception of internal and external effectiveness. The upper and lower gradients showed a significant difference depending on the type of coverage and the hours, as well as the hourly coverage interaction (P<.0001). The alternative system for quail with ceramic tiles painted on the external face in white and with geopaint are a good alternative to reduce the internal temperature in the sheds.
