Purpose
Most dairy operations use liquid manure systems, however, if you are a dairy farmer who is investigating alternative manure management systems, bedded pack may be an option for you. For dairy farms to remain sustainable and economically viable, production systems that improve the cow health, minimize manure handling costs, and reduce potential environmental impacts are needed. The compost bedded pack dairy barn is an alternative dairy system with solid manure handling options. Its potential for positive impacts on milk production and cow health, as well as the ability to handle manure as a dry material, have resulted in increased interest in the system.
The Ohio State University and the University of Kentucky have conducted preliminary research to analyze design and management recommendations; document current practices; and evaluate milk production, animal health, indoor air quality, and manure handling of the bedded pack dairy system. This multi-state workshop educational program has been developed for dairy producers, professional consultants, and NRCS engineers to learn about design considerations, best management practices, production effectiveness, and impacts on animal health for dairy bedded pack systems. The workshop will help dairy producers make knowledge based decisions in considering adoption of the compost bedded pack system for profitable and sustainable dairy operations.
