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?

Adult maintenance (non-breeding, fiber animals)8–10%Slightly low add some alfalfa or a camelid pellet
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 female12–14%Too low needs a protein supplement
Weanling / yearling (growing)14–16%Too low needs a protein supplement
Working herdsire10–12%Too low needs a protein supplement
Senior (12+ years)10–12%Too low needs a protein supplement

How much native prairie hay 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.
