Compost bedding pack (CBP) barns have been receiving increased attention as an
alternative housing system for dairy cattle. Thus, a systematic investigation of the primary
management practices of dairy cattle in CBP barns in the state of Minas Gerais (Brazil) has proven
to be of environmental and economic relevance. The aim of this research was to summarize the
compost bed data, barn dimension data and to determine the major interactive factors in the
success of bed composting from qualitative and quantitative methods. Data for this study was
collected from 16 CBP barns, distributed throughout the southern state of Minas Gerais (Brazil)
between March 2017 and July 2018. These data were used to describe the building layouts and
dimensions, to identify barn management practices, and to characterize the compost bedding
material concerning moisture content. The majority of these barns had feed alleys and driveways;
overshot ridges with frequent orientation from NE to SW; bedding process and aeration using
mechanical tillage. The average bedding moisture content was found to be 36.9 ± 5.2% (w.b.).
Based on the information found, it is possible to evaluate that there is still no defined construction
pattern, with a high variation of size and technologies employed.
