Crop & Livestock Automatic Calculations

For calculating crops income, we're going to assume crop prices are relatively high

Enter numbers from your farm, or use a number within the Typical Range.

Starting with high crop prices means we end up with a

conservative estimate of the value of adding livestock to an operation.

All numbers should be per year, for a typical year.

The sensitivity analysis tabs will show what happens if crop prices change.

You can enter expenses by category, OR just enter total crop expenses in line 39, whichever is easier.

Loss reduction due to cover crops & forage, 56%

3.9 tons x 0.56 = 2.2 tons retained on forage fields

Estimate if cover cropped fields are also row-cropped:

1.5 tons of soil retained on row-cropped + cover cropped fields

Range: $389 to $852 per cropped acre. Median: $589 per cropped acre.

Again, enter your best top-of-mind estimate and don't worry about being exact.

Grain consumption by livestock class estimated from Extension publications (below)

Breeding stock are assumed to be fed the same as heavy feeders.

Example scenario: 180 days grazed; 0 days fed grain; 185 days fed hay, haylage, etc.

Bushel weights: 56 lbs/bu corn, 60 lbs/bu soybeans.

Price assumptions: $6/bu corn, $15/bu soybeans

Example scenario: 240 days grazed; 180 days fed grain; 60 days fed hay, haylage, etc.

Example scenario, Heavy feeders: 60 days grazed; 75 days fed grain; 15 days fed hay, haylage, etc.

Example scenario, Fed cattle, seasonal feedlot: 0 days grazed, 175 days fed grain; 175 days fed hay, haylage, etc.

Example scenario, Fed cattle, year-round feedlot: 0 days grazed; 365 days fed grain; 365 days fed hay, haylage, etc.

Hay consumption by livestock class estimated from Extension publications (below)

Breeding stock are assumed to be fed the same as heavy feeders.

You can enter expenses by category, OR just enter total livestock expenses in line 76, whichever is easier.

Hay amounts are on as as-fed basis, assuming 12% moisture.

It is fine to leave a line blank or enter zero if it doesn't apply to you.

All forage fed is assumed to be hay for purposes of these calculations.

Livestock costs will be calculated per head sold, regardless of # of head present.

Range: $406 to $1,632 per head sold. Median: $847 per head sold.
