Goat Milk Production Calculator
Estimate daily goat milk production based on breed, lactation stage, feed quality, and nursing kids. Calculate cheese yield and feed costs.
About this calculator
This calculator estimates daily and monthly goat milk output by layering four adjustments onto a doe's peak breed productivity. The lactation-month factor follows a realistic curve rather than a flat average: production ramps up in month 1 (70% of peak), holds at 100% through months 2 and 3, and steadily declines through month 10 (down to 35%), reflecting how milk yield naturally rises after kidding and tapers as the lactation cycle winds down. A feed-quality factor on a 1-to-5 scale further scales output from 60% of potential on browse-only feed up to 110% on an optimized dairy ration, since nutrition is the single biggest lever on yield after genetics. Nursing kids reduce the milk actually available for collection by 15 percentage points per kid, capped at a maximum 50% reduction — the milk doesn't disappear, but it goes to the kids rather than the milking pail.
Multiplying breed productivity by all three factors gives daily milk per doe, which is then scaled by herd size and converted to gallons using the standard 8.6 pounds per gallon for goat milk. Monthly production is a straight 30-day multiplication, and cheese yield assumes roughly 1 pound of cheese per gallon of milk processed — a reasonable rule of thumb for soft and semi-hard cheeses, though hard aged cheeses typically yield less. Feed cost per gallon divides an assumed flat $1.50/day/doe feed cost by gallons produced, so it reflects feed only, not labor, vet care, or bedding.

How to Use This Calculator
- Enter Doe Count (number of milking does) and select Breed Productivity (low/medium/high breeds like Nigerian Dwarf vs. Nubian vs. Saanen).
- Set Lactation Month (1–10) — production peaks around month 2–3 and declines toward the end of the lactation cycle.
- Rate Feed Quality Score (1–5) since nutrition is the primary driver of milk production after genetics.
- Enter Kid Count — kids nursing reduce the milk available for harvest proportionally.
- Review Daily Milk (lbs) and Daily Milk (gal) to plan milking schedules and dairy processing capacity.
- Use Monthly Cheese Yield (lbs) and Feed Cost per Gallon to evaluate the economics of your dairy operation.
How the result changes with Number of Does

| 2.25 | 16.2 lbs | 1.88 gal |
| 4.5 | 32.4 lbs | 3.77 gal |
| 7.5 | 54 lbs | 6.28 gal |

Frequently Asked Questions
Why does entering Lactation Month 1 give lower output than month 3, even with the same doe?
The calculator applies a lactation-curve factor that starts at 70% of peak in month 1, rises to 100% through months 2 and 3, then steadily declines toward 35% by month 10. This mirrors real dairy physiology — milk yield builds after kidding, holds at peak for a couple months, and gradually tapers as the lactation cycle progresses, so the same doe's Breed Productivity value produces very different daily output depending on where she is in her cycle.
How much does upgrading Feed Quality actually change my milk output?
Feed quality is a direct multiplier on daily output, ranging from 0.6 at the lowest setting (browse only) up to 1.1 at the highest (optimized dairy ration) — nearly double the output between the worst and best feed scenarios, holding breed and lactation stage constant. It's applied on top of the lactation-month factor, so the two adjustments compound rather than replace each other.
Why is Kid Count's effect on milk capped at 50% instead of scaling indefinitely?
Each nursing kid reduces available milk by 15 percentage points, but the calculator caps that reduction at 50% regardless of how many kids are nursing. This reflects that a doe with several kids will still produce some milk you can collect after the kids have nursed their fill — the reduction isn't meant to model total milk diverted, just a practical upper bound on how much collection capacity nursing kids take away.
Is the Monthly Cheese Yield figure accurate for any type of cheese?
It assumes roughly 1 pound of cheese per gallon of milk, which is a reasonable rule of thumb for soft and semi-hard cheeses like chevre or feta. Hard, aged cheeses lose more moisture and typically yield less cheese per gallon than this calculator estimates, so treat the figure as an upper-bound approximation for those styles.
