My cool season grasses that we grow in Wisconsin tested 24.37% Crude Protein (CP) with a Relative Forage Value of 218.27. The Total Digestible Nutreints (TDN) was 71.54% of dry matter. Dry Matter (DM) was 73.13%. Non Fiber Carbohydrate was 26.14% of DM and Fat was 3.20%. The test sample was produced in June, 03. I am used to southern grasses that run about 7 - 14% CP. We can produce very high quility forage in Wisconsin that is digestable by cattle. No need to supplement protien or energy.
