Mr. Graham:

Enclosed is information on our CLOSED CIRCUIT ODOR AND WASTE MANAGEMENT SYSTEM, which we have developed for use at hog and dairy farms.

Full testing has been done, the results are shown.

Highlighting benefits:

                Improved mortality rates.

Fewer incidences of PRRS, Ecoli Scours, Ileitis and other viral and bacterial infections.

                Reduced use of prophylactic medications.

                Improved lean weight percentages.

                Fewer feed days to market weight.

We feel this technology should be owned and administrated by the industry and are willing to work with you to train installation personnel.

When would it be convenient to visit you?

Best regards,

John Candler
