Temperatura e umidade da cama em instalações Compost Barn com diferentes sistemas de ventilação

The objective of this study was to evaluate the spatial distribution of the variables bed temperature and humidity in compost dairy barn (CBP) with different ventilation systems. The facilities presented wood sawdust as bed material. The CBPs were divided into meshes with 40 equidistant points, in which the bed temperature levels were manually collected on the surface (tc-sup) and at a depth of 0.20 m (tc-20), as well as bed samples at both depths, which were used to determine moisture (Uc). The geostatistical technique was used to evaluate dependence and spatial distribution. The results showed the occurrence of dependence and spatial variability, and the lowest levels were verified for installation with HVLS ventilation. The results obtained allow us to conclude that ventilation influences the variables analyzed.
