Abstract
The mycotoxin cyc1opiazonic acid (CPA) was detected in the milk from ewes and the eggs from chickens that were given oral doses of the toxin. Three lactating ewes were given CPA for 2 days at a rate of 5 mg/kg of live weight. Thin-layer chromatographic analyses of dried, defatted milk samples showed that CPA was present in milk at an average concentration of 236 ng/g within 24 h of the illstdose. The concentration of CPA reached a higb of 568 ng/g, but none was detectable by the ninth day after the first dose. Laying hens were given oral doses of CPA in two separate studies: an acute study over 9 days with dose groups of 0.0, 2.5, 5.0, and 10.0 mg/kg of live weight and a chronic study over 4 weeks with dose groups of 0.0, 1.25, and 2.5 mg/kg of live weight. Eggs from birds in all dose groups throughout both studies contained CPA. The concentrations of CPA were much higher in egg whites than in egg yolks, averaging approximately 100 and 10 ng/g, respectively.
