Pennsylvania has over 2,700 independent producers with over 320,000 sows and pigs with the majority of farms having less than 25 animals per farm. These small farms generated over $ 2.3M in sales in 2012 according to the national Agricultural Statistics Service (NASS).
Penn State Extension
Penn State Extension has resources covering swine production. The Penn State Extension website contains information covering production and management, herd health, and what medications may be currently used without a veterinarian's supervision. The list of these medications is due to change at the end of 2016 so you should consult this site for additional information.
The Pork Checkoff provides information covering sales data and also has a list of cuts derived from the market hog. The site also covers the responsible production of market hogs.
For information regarding swine building idea plans, check the agricultural engineering site for building plans. You should use these plans as a general outline but you should consult an agricultural engineering or experienced builder for more specific details.
Marketing of your pork production may take several forms. You may direct market whole animals live, whole animals slaughtered and portions of animals (halves or quarters) or even individual cuts. A source of determining prices for live animals is the United States Department of Agriculture, Agricultural Marketing Service's report on pork slaughter reports. These prices will be a starting point for selling your pork. Depending on your production (feeder pigs or market hogs), you may use these reports to better determine when to sell your production.
