Saanen & Sable Goat Weight Chart by Age (Doe & Buck)
Saanens — and their colored variant, the Sable — are among the largest dairy breeds, with mature does running 130 to 170 lbs and bucks up to 210. Often called the "queen of the dairy goats," the Saanen is built for sheer milk volume. A big frame and a heavy udder both demand serious nutrition, so weight on a Saanen is really a question of keeping up with what the breed asks of itself. The chart and calculator below cover both Saanens and Sables (they are the same breed, differing only in color).
Enter an age — even an in-between age like 2, 4, or 9 months. Add your goat's current weight to see whether it's on target for a Saanen of that age.
Wrap a soft tape snugly around the chest right behind the front legs (the heart girth), then measure body length from the point of the shoulder to the pin bone. Both in inches. Works for any goat.
Saanen Weight Chart
Expected weights for Saanen does and bucks at key ages. The calculator above is built from these ranges and fills in the gaps between them.
| Age | Does (lbs) | Bucks (lbs) |
|---|---|---|
| Birth | 6 to 10 | 7 to 11 |
| 1 month | 15 to 22 | 17 to 25 |
| 3 months | 32 to 52 | 36 to 58 |
| 6 months | 55 to 85 | 65 to 95 |
| 1 year | 85 to 130 | 110 to 160 |
| Adult (2+ years) | 130 to 170 | 160 to 210 |
Saanen Growth, Month by Month
Saanen kids start large — 6 to 11 lbs at birth — and grow fast on a big frame. They put on size quickly through the first six months and need ample protein and energy to do it well; a fast-growing large-breed kid that is under-fed will show a flattened growth curve. A doe reaches breeding weight readily, often by 7 to 9 months.
The breed's enormous milk volume is the headline once she freshens: a heavily-producing Saanen burns through energy, and holding body condition through peak lactation is the central management challenge.
Saanen-Specific Things to Watch
- White skin means sunburn risk. Saanens (and light Sables) can sunburn and are prone to photosensitivity — make sure there is shade, especially for kids and pink-skinned areas.
- Huge milk volume drains condition. A top Saanen can milk off her own back. Feed to the milk and watch body condition closely through early lactation.
- Big, fast frame needs fuel. Under-feeding a fast-growing Saanen kid stalls the growth curve — keep protein and energy adequate.
- Keep up parasite checks. Large size doesn't grant immunity; stay on FAMACHA and fecals.
How to Weigh Your Saanen
The tape estimator above does the math from two measurements.

Frequently Asked Questions
How much should a Saanen goat weigh?
Saanen does reach about 130 to 170 lb as adults and bucks 160 to 210 lb, from a large 6 to 11 lb birth weight. They're one of the biggest dairy breeds and grow fast on a big frame through the first six months.
At what weight should I breed a Saanen doe?
About 80 to 90 lb, which the breed's fast growth often reaches by 7 to 9 months. She needs to enter her first lactation with real frame and condition, because a Saanen is asked to milk harder than almost any other breed.
How fast do Saanen goats grow?
Fast; they start large and put on size quickly through the first six months, needing ample protein and energy to do it well. An under-fed fast-growing large-breed kid shows a flattened growth curve, so keep the nutrition up during that stretch.
What is the main management challenge with Saanens?
Holding body condition through peak lactation. A Saanen's enormous milk volume burns through energy, so a heavily-producing doe can pull weight off her own back; keeping her fed well enough to hold condition while milking is the central challenge.
How do I weigh a Saanen goat without a scale?
Use the heart-girth method: wrap a soft tape around the chest just behind the front legs, measure body length from the point of the shoulder to the pin bone, and run both through the calculator above. It estimates weight within about 5 to 10%.
