돼지 우리 깔집용 왕겨에서의 ochratixin A 검출

Ochratoxin A contaminatio in rice chaffs used as floor beddings of pigsty

A sporadic incidence of porcine nephropathy suspecting mycotoxicosis was encountered in piglets of a farm. TLC and HPLC were employed to identify, confirm and quantitate the causative mycotoxin in animal feeds and rice chaffs used as floor beddings of the pigpens. As a result, ochratoxin A was detected in the rice chaffs on floor beddings with concentrations of 22.4 ppb-1.17 ppm, and the rice chaffs stocked to be used were also contaminated with ochratoxin A at levels of 89.1-997ppb. In conclusion, the porcine nephropathy was caused by ochratoxin A contaminated in the rice chaffs used as floor beddings for the piglets.
