Looking for information on dry hog manure handling systems



Dear Sanet Users,

      A colleague of mine with EPA's Region 7 in Kansas City, KS, asked me to 
post a question to the Sanet group concerning raising hogs and handling their 
manure.  Does anyone know examples of hog farms that use dry manure handling 
methods -- such as bedding, or compressed air to blow the manure down a 
concrete slope into a trough?  He remembers seeing the latter, maybe in the 
1960's.  Also, is there any information on raising hogs on bedding and the 
economics of doing so?  And how was the manure handled?  Was it composted?  So 
far I have sent him the following papers:

Honeyman, M., "Vastgotmodellen: Sweden's sustainable alternative for swine 
production," American Journal of Alternative Agriculture, Vol. 10, No. 3, 1995, 
pp. 129-132.

Luymes, J., "Eco Barn: A Description of an Animal Welfare-Friendly Hog Feeder 
Facility," Presented at the 1995 Pacific Northwest Section Meeting Sponsored by 
ASAE, Harrison Hot Springs, British Columbia, October 1-3, 1995.

      Are there other articles to recommend?  Thank you in advance for your 
help.
