Goat Feed Calculator
Calculate daily feed requirements for goats by body weight, production stage, and breed. Enter values for instant results with step-by-step formulas.
Formula
Daily DMI (lbs) = Body Weight x DMI% x Breed Multiplier
Where DMI% is the dry matter intake percentage based on production stage (3% maintenance to 5% lactating), and Breed Multiplier adjusts for dairy (1.1x), meat (1.0x), or fiber/miniature (0.85x) breeds. Grain and hay proportions are then calculated based on the production stage requirements.
Worked Examples
Example 1: Small Dairy Herd of 10 Lactating Does
Problem: Calculate daily and monthly feed requirements for 10 dairy goats averaging 120 lbs each in lactation with average-quality hay.
Solution: DMI per goat = 120 x 0.05 x 1.1 (dairy) = 6.60 lbs/day\nGrain (40%) = 6.60 x 0.4 = 2.64 lbs/day\nHay (60%) = 6.60 - 2.64 = 3.96 lbs/day\nDE = (3.96 x 0.9) + (2.64 x 1.4) = 7.26 Mcal/day\nMonthly hay per goat = 3.96 x 30 = 118.8 lbs\nMonthly hay for herd = 118.8 x 10 = 1,188 lbs (~24 bales)
Result: Daily per goat: 6.60 lbs DMI (3.96 hay + 2.64 grain) | Herd monthly: 1,188 lbs hay
Example 2: Meat Goat Herd on Maintenance
Problem: Calculate feed for 20 meat goats at 80 lbs each on maintenance with average hay.
Solution: DMI per goat = 80 x 0.03 x 1.0 (meat) = 2.40 lbs/day\nGrain (0%) = 0 lbs/day (maintenance needs no grain)\nHay (100%) = 2.40 lbs/day\nDE = 2.40 x 0.9 = 2.16 Mcal/day\nMonthly hay per goat = 2.40 x 30 = 72.0 lbs\nMonthly hay for herd = 72.0 x 20 = 1,440 lbs (~29 bales)
Result: Daily per goat: 2.40 lbs hay only | Herd monthly: 1,440 lbs hay, no grain needed
Frequently Asked Questions
How much feed does a goat need per day?
A goat generally needs to consume between 3% and 5% of its body weight in dry matter each day, depending on its production stage and breed type. A 100-pound maintenance doe in a non-productive state requires approximately 3 pounds of dry matter per day, primarily from good-quality hay or browse. Lactating does have the highest nutritional demands, needing up to 5% of their body weight in dry matter with a significant portion coming from concentrates or grain to support milk production. Growing kids also have elevated needs at about 4% of body weight because they are building muscle and bone tissue. The exact amount varies with environmental conditions, as goats in cold climates or on hilly terrain expend more energy and require additional feed.
How accurate are the results from Goat Feed Calculator?
All calculations use established mathematical formulas and are performed with high-precision arithmetic. Results are accurate to the precision shown. For critical decisions in finance, medicine, or engineering, always verify results with a qualified professional.
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
