Influence of low levels of ochratoxin A on egg production, egg-shell stains, and serum uric-acid levels in Leghorn-type hens.

Ochratoxin A, when fed at 0.0, 0.5, or 1.0 PPM to adult white Leghorn chickens, produced significant reduction in egg production and an increase in serum uric-acid levels, with a concomitant increase in egg-shell stains. These egg-shell stains were clinically similar to those described in the case report.
