Boer Goat Weight Chart by Age + Average Daily Gain (Doe & Buck)
The Boer is the meat breed — heavily muscled, fast-growing, and built to put on pounds. Mature does run 150 to 225 lbs and bucks can top 300. For Boers, weight is a different conversation than it is for the dairy breeds: it is not only a health check but a production metric. Average daily gain, weaning weight, and time to market weight are the numbers that decide profitability. The chart and calculator below are scoped to Boers.
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 Boer 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.
Boer Weight Chart
Expected weights for Boer 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 | 7 to 10 | 8 to 11 |
| 1 month | 18 to 28 | 20 to 32 |
| 3 months | 40 to 60 | 45 to 70 |
| 6 months | 70 to 100 | 80 to 115 |
| 1 year | 100 to 150 | 120 to 180 |
| Adult (2+ years) | 150 to 225 | 200 to 300 |
Boer Growth, Month by Month
Boer kids are born at 7 to 11 lbs and gain fast — commonly 0.5 to 0.75 lbs per day or more on good nutrition, well ahead of dairy kids. They are bred for rapid muscling and early finishing, so the growth curve through the first six months is steep, and weaning weight is a key benchmark for how a kid (and its dam's milking) is performing.
Because the goal is often market weight rather than just "healthy," tracking gain over time matters even more here — a kid behind on average daily gain is costing you feed-days, and one well ahead may be ready to market sooner.
Boer-Specific Things to Watch
- Parasites love fast-growing kids. Boers, especially in warm, humid climates, are notably susceptible to barber pole worm. Stay on FAMACHA and fecals — a heavy load tanks gain and can kill kids fast.
- Track average daily gain, not just total weight. Gain over time is the production number. A kid behind on ADG is eating into your margin.
- Over-conditioning is real in show and pet Boers. An over-fat doe has more kidding trouble and reduced fertility — feed for muscle and frame, not fat.
- Weaning weight reflects the dam, too. A light litter at weaning can mean a doe that isn't milking well — worth checking before you blame the kids.
How to Weigh Your Boer
The tape estimator above does the math from two measurements. For the full rundown — hanging scales, the bathroom-scale trick, livestock scales, and when each is worth it — see the complete goat weight guide, which also covers the general growth milestones and warning signs that apply to every breed.
