DPC 110, Guidelines for Managing Compost Bedded-Pack Barns

Item #: DPC-110

Published: 2013

Pages: 19

This guideline is designed to provide general information about proper construction and management of compost bedded-pack dairy barns in the United States. The compost bedded pack barn consists of a large, open resting area, usually bedded with sawdust or dry, fine wood shavings that are composted in place, along with manure, when mechanically stirred on a regular basis. Facility design, ventilation, timely addition of fresh, dry bedding, frequent and deep stirring, and avoidance of overcrowding are the keys to a good working compost bedded-pack barn.

DISCLAIMER: The DPC is not responsible for the use or application of the information provided in this Guideline. It is the responsibility of the user to ensure that the information addresses their needs and that any action taken complies with appropriate regulations and standards.
