Abstract

This study assesses the levels of aflatoxin B1 contamination in broiler feed samples that were taken from farms in the Duhok Governorate between January 2020 and August 2022. An ELISA technique used to evaluate 213 feed samples in total. The data indicated a significant increase in aflatoxin B1 contamination, with 22 samples (10.32%) testing negative and 191 samples (89.67%) testing positive. Every year from 2020 to 2022, the proportion of samples that tested positive for contamination increased, going from 76.36% in 2020 to 91.50% in 2021 and 100% in 2022. The concentration of aflatoxin B1 also showed an increased trend, with mean values of 5.351 ppb in 2020 and 6.338 ppb in 2022. Descriptive statistics indicated considerable variability in aflatoxin levels, with the highest mean observed in 2022. ANOVA results confirmed statistically significant differences between years (F-value = 4.36, p-value = 0.014), highlighting a concerning escalation in contamination levels. This rise emphasizes the need for improved management and monitoring techniques to reduce aflatoxin exposure. The results are consistent with prior research showing elevated levels of contamination brought on by environmental factors and feed management techniques. The research highlights the significance of enforcing more stringent quality control protocols to guarantee feed safety and safeguard the well-being of chickens.
