When you click on a state, it will open up a document. You will use stock codes to search within the document (use the "Find" function on your computer - usually in a drop down menu such as under the "Edit" menu, and type in the code you are interested in and it will find all instances of that code in the doc). Then you will find NPIP places that have that breed. Stock codes are listed on the left side of the above link.
The codes you are interested in are as follows:
"
T " refers to Meat Production Stocks

"
R " refers to Other large breeds and varieties

For example, in Ohio where I live, I found 26 instances of R17. Some of these were codes that were more than R17, such as R171...but still found several Delaware R17. But, I was unable to find T44 in Ohio. When I looked up R17 in Texas and Oklahoma, I did find matches. Hopefully this helps you in your search.
