Goat Feed Calculator

Calculate goat feed, hay, bales, and monthly cost

Estimate how much hay, grain, and loose mineral your goats need for a week, month, winter, or full year. Adjust body weight, forage quality, waste, bag size, bale weight, and prices to match your herd.

How to use this goat feed calculator

  1. Enter your goat count and the closest goat type.
  2. Use the suggested body weight, or enter your herd's average weight.
  3. Choose a hay rate and pasture offset. Three percent of body weight is a useful starting estimate for planning hay.
  4. Add any daily grain ration, package sizes, and prices to estimate bags, bales, and cost.

Quick goat feeding example

For two 120 lb standard goats eating hay at 3% of body weight, plan around 7.2 lb of hay per day before waste. With a 10% hay waste buffer, that becomes about 238 lb for 30 days, or roughly five 50 lb bales.

Goat feed calculator FAQ

How much feed does a goat need per day?

As a rough planning range, goats often need dry matter equal to about 2% to 4% of body weight per day. For a 120 lb goat, that is roughly 2.4 to 4.8 lb of dry feed daily before adjusting for pasture quality, waste, pregnancy, lactation, growth, or weather.

How much hay should I buy for winter?

Choose the 150 day winter period, enter your goat count and average weight, then divide the hay total into your local bale size. Add extra if winters are long, bales are light, your goats waste hay, or pasture is unavailable.

Do all goats need grain?

No. Many mature wethers and dry does do well on quality forage, minerals, and clean water. Dairy goats, growing goats, late-pregnancy does, and thin animals may need measured grain or a balanced concentrate. Follow feed-label limits and local livestock advice.

Why does hay waste matter so much?

Goats often pull hay from feeders, sort leaves and stems, or refuse hay that falls on damp ground. A waste buffer helps the buying estimate match what you actually need on hand.
