Abstract :The aim of this study was to determine the effects of seasonal variations on the occurrence of total aflatoxin insert ignore into journalissuearticles values(AFTotal);, aflatoxin B1 insert ignore into journalissuearticles values(AFB1);, ochratoxin A insert ignore into journalissuearticles values(OTA);, and total fumonisin insert ignore into journalissuearticles values(Ftotal); in the commercially mixed ruminant feed obtained from feed mills located in Ankara, Kırıkkale, Çankırı, Çorum, and Kırşehir provinces using the enzyme-linked immunoassay insert ignore into journalissuearticles values(ELISA); method. To represent the annual production, 22 samples were collected every quarter over 1 year insert ignore into journalissuearticles values(a total of 88 samples); starting in September 2012. AFTotal and AFB1 were detected in 72 samples insert ignore into journalissuearticles values(81.81%);, OTA in 84 samples insert ignore into journalissuearticles values(95.45%);, and Ftotal in 83 samples insert ignore into journalissuearticles values(94.31%);. When seasonal changes were taken into consideration, the highest levels of AFTotal, AFB1, and Ftotal insert ignore into journalissuearticles values(13.57 ± 8.78 ppb, 8.54 ± 6.02 ppb, and 0.70 ± 0.88 ppm, respectively); were found in the summer, while the highest OTA level insert ignore into journalissuearticles values(57.69 ± 14.59 ppb); was observed in the spring. The results of high-performance liquid chromatography methods confirmed the results of the ELISA method. Consequently, although most of the feed samples were contaminated with mycotoxins, all the amounts were within the limits allowed for feedstuffs in Turkey.
