Gooch, Curt2014-07-162014-07-162006-09-01https://hdl.handle.net/1813/36957For the last several decades, common freestall barn configurations have been two, three, four, and six rows of stalls. As herd sizes have grown, these barns have become much longer while the widths have remained essentially the same other than a few additional feet added here and there base on improving cow stall use and feed access. Experience has shown that many naturally ventilated barns experience shortcomings, especially if they are located on a site that is not well exposed to consistent summertime air movement. As a result, the concept of tunnel-ventilating barns was adopted from the swine and poultry industries over 10 years ago and adjusted to meet the needs of dairy facilities.en-USdairy barnshousing barnsfreestalldesigntunnel ventilationarticle
