Goat Feed Requirement Calculator

Work out goat feed requirement instantly with clear inputs, formula shown and shareable results.

About Goat Feed Requirement Calculator

Goats eat 3-4% of body weight as dry matter, proportionally more than cattle because of their smaller size and faster metabolism. Splitting the ration into concentrate and roughage and converting the roughage back to green fodder at about 25% dry matter gives the daily cut-and-carry quantity.

Formulas

Goat ration

DM per goat = body weight x DMI %; herd DM = per goat x number

Green fodder

Green fodder = roughage DM / 0.25 (fresh basis)

Worked example

With the default values below, Goat Feed Requirement Calculator returns Herd Dry Matter Requirement of 52.500. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Do goats need concentrate at all?

Maintenance on good browse needs none. Concentrate is justified for late pregnancy, lactation and finishing kids, typically 200-400 g a day.

Why do goats waste so much fodder?

They are selective browsers and reject trampled or soiled feed. Raised feeders and small frequent offerings cut waste from 30-40% down to under 10%.
