| Abstract | ||||
| Seasonal climatic changes significantly affect mycotoxin contamination in poultry feed and tissues, with warmer conditions promoting fungal growth and toxin production. A surveillance study was conducted in Behera Governorate, Egypt, to assess seasonal mycotoxin contamination (specifically, total aflatoxins and ochratoxin A) in broiler feed and tissues, including the liver and kidneys. A total of 300 samples were collected, with 150 samples taken during winter and 150 during summer. This study investigates the seasonal variations in mycotoxin contamination in broiler feed and tissues, evaluates the prevalence of fungi and aflatoxin production, and examines the effectiveness of propionic acid as an antifungal agent to ensure feed safety and protect poultry health. The results indicated higher contamination levels during the summer months. Fungal prevalence was significant across both seasons, with Aspergillus flavus identified as the dominant mould, particularly in summer, leading to increased aflatoxin production. The findings underscore the importance of proper storage practices and seasonal monitoring to mitigate fungal growth and reduce mycotoxin risks. Histopathological analyses revealed the toxic effects of mycotoxins, which manifested as severe liver and kidney damage in affected birds. Furthermore, the study demonstrated that a 0.5% solution of propionic acid effectively inhibits mould growth. These results highlight the necessity for antifungal strategies, thorough monitoring, and optimized feed management to ensure feed safety and protect poultry health. | ||||
