Determining the relationship between the concentration of aflatoxin B1 in feed components and aflatoxin M1 in raw milk of industrial dairy farms in Joghtai city:
This study aimed to investigate the relationship between aflatoxin B1 (AFB1) concentration in feed and aflatoxin M1 (AFM1) in raw milk from industrial dairy farms in Joghatay, Iran. To assess AFB1 and AFM1 and determine their association, samples of feed (concentrate, soybean meal, corn silage) and milk were collected in three seasons (winter, spring, and summer). AFB1 and AFM1 were measured using the ELISA method. Data were analyzed using the SAS software and the GLM procedure. The highest milk aflatoxin contamination was observed in summer (3.000±0.003 ng/L) and the lowest in winter (0.013±0.003 ng/L). Among the three feed samples, the highest AFB1 contamination was found in corn silage in summer (14.66±1.49 μg/kg) and the lowest in soybean meal in winter (3.00±0.00 μg/kg). During summer, dairy cows consume more corn silage stored for nearly a year, resulting in higher AFB1 intake and consequently higher AFM1 in milk.
