Dairy Cow Ration

Professional analysis system based on NRC 2001 / NASEM 2021 standards.

Scientific Standard: This tool is based on NRC 2001 and the latest NASEM 2021 "Dairy Cattle" requirement models.
  1. Fill in the cow profile on the left: body weight, condition score, lactation stage, milk yield and fat/protein percentages.
  2. On the right, type the daily amount of each feed you use as fed (fresh weight) in kg — the dry matter conversion is automatic. Entering a price per kg is optional and shows the cost.
  3. Click "Analyze Ration".
  4. On the results page, compare total dry matter intake with the Est. DMI value, then increase or decrease feed amounts according to the NEL and protein balance and recalculate.
