Typical nutrient profile
| Measure (dry-matter basis) | Typical value | Rating for alpacas |
|---|---|---|
| Dry matter | 91% | As-fed moisture: dry, stores well |
| Crude protein | 4.5% | Very low — not a sole feed |
| ADF (acid detergent fiber) | 48% | Poor — stemmy |
| NDF (neutral detergent fiber) | 72% | Very fibrous |
| TDN (energy) | 46% | Low energy |
| Calcium | 0.25% | |
| Phosphorus | 0.07% | |
| Ca : P ratio | 3.6 : 1 | Calcium-heavy |
| NSC (sugar + starch) | 4% | Low sugar/starch |
| Fat | 2.5% |
Typical averages from published feed-composition tables. Hay varies enormously with species, maturity, soil and curing — a forage test (about $25–$40) is the only way to know what your hay provides.
Does it meet each life stage's protein needs?
| Life stage | Protein target | Oat Straw (4.5% CP) |
|---|---|---|
| Adult maintenance (non-breeding, fiber animals) | 8–10% | Too low needs a protein supplement |
| Pregnant female (months 1-8) | 10–12% | Too low needs a protein supplement |
| Pregnant female (last 3 months) | 12–14% | Too low needs a protein supplement |
| Lactating female | 12–14% | Too low needs a protein supplement |
| Weanling / yearling (growing) | 14–16% | Too low needs a protein supplement |
| Working herdsire | 10–12% | Too low needs a protein supplement |
| Senior (12+ years) | 10–12% | Too low needs a protein supplement |
How much to feed
As the main forage, a typical 150 lb (68 kg) alpaca eats roughly:
| Life stage | Per day (as fed) | Per month |
|---|---|---|
| Adult maintenance (non-breeding, fiber animals) | 3.0 lb (1.3 kg) | 90 lb |
| Pregnant female (months 1-8) | 3.0 lb (1.3 kg) | 90 lb |
| Pregnant female (last 3 months) | 3.3 lb (1.5 kg) | 100 lb |
| Lactating female | 3.8 lb (1.7 kg) | 115 lb |
| Weanling / yearling (growing) | 4.1 lb (1.9 kg) | 125 lb |
| Working herdsire | 3.3 lb (1.5 kg) | 100 lb |
| Senior (12+ years) | 3.1 lb (1.4 kg) | 95 lb |

Frequently asked questions
Is oat straw good for alpacas?
With about 4.5% crude protein it is very low — not a sole feed for alpacas.
How much oat straw does an alpaca eat per day?
About 3.0 lb (1.3 kg) per day for a 150 lb adult at maintenance if fed as the main forage.
