AgSource Analysis Calculations

Legumes - Hay and Haylage

NEL = 1.016 - (.0114 x ADF)

TDN = 4.898 + (NEL x 89.796)

Mixed Legume - Legume/Grass Hay and Haylage

NEL = 1.068 - (.0138 x ADF)

TDN = 4.898 + (NEL x 89.796)

Grass - Grass Hay and Haylage

NEL = 1.122 - (.016 x ADF)

TDN = 4.898 + (NEL x 89.796)

Corn Silage

NEL = 1.122 - (.016 x ADF)

TDN = 31.4 + (NEL x 53.1)

Small Grains - Oats, Barley, Wheat, Wheat Midds, etc.

NEL = .9265 - (.00793 x ADF)

TDN = 4.898 + (NEL x 89.796)

TMR -TMR Mixes, Bunk Mixes, CS and Haylage Mixes

TDN = 93.53 - (1.03 x ADF)

NEL = (TDN x .011123) - .05448

Grain Mix - Hog Feeds, Commercial Dairy Feeds, Corn Gluten, Wet Brewers Grain, Oat Hominy

NEL = (TDN x .011123) - .05448

TDN = 81.41 - (.48 x ADF)

Ear Corn - High Moisture and Dry

NEL = 1.036 - (.0203 x ADF)

TDN = 99.72 - (1.927 x ADF)

Top
Shelled Corn - High Moisture and Dry, Corn Screenings, Soybean Meal, Raw Soybeans, Soycakes, Whole Cottonseed, Canola Meal, Sunflower Seeds, Linseed Meal, Oils

NEL = .905 - (.0026 x ADF)

TDN = 92.22 - (1.535 x ADF)

Small Grain Forage - Peas and Oats, Oatlage, Milo, Barlage, Tripper, Millet, Sudan, Sorghum and Sudan, Corn Silage and Sorghum

NEL = .7936 - (.0034 x ADF)

TDN = 4.898 + (NEL x 89.796)

NET Energy Gain

If Dry Matter < 67

NEg = (.0168 x TDN) - .715 or NEg = (.0109 x TDN) - .312

Relative Feed Value (RFV) -Legume, Mixed and Grass Hay and Haylages only

Digestible Dry Matter DDM = 88.9 - (ADF x .779)

Dry Matter Intake DMI = 120 ÷ NDF

Relative Feed Value RFV = (DDM x DMI) ÷ 1.29
