  Mold contamination of feeds is a common problem in poultry industry. The aim of this study was to investigate mold contamination of laying hen diets around Tehran (Shahriar and Malard). For this purpose, 5 laying poultry farms were subjected to random sampling so that a total of 60 samples were taken from each poultry farm during four consecutive seasons. For counting and separation of molds, surface cultivation in the culture medium was used. After the primary growth of molds, slide culture was prepared and the macroscopic and microscopic indices of molds were defined. Seven types of molds were separated by macroscopic and microscopic studies. In terms of the total number of molds in laying poultry farms in each season, no significant difference was observed, but between seasons a significant difference was observed (p<0.001), as such, the number of molds in autumn (3.11±0.10 Log CFU/g) and winter (3.35±0.10 Log CFU /g) showed the highest level of contamination in all laying poultry farms. Also, the lowest number of mold contamination was observed during the spring and summer in all laying poultry farms. Fusarium, Penicilium, Aspergillius flavus, Mucor, Aspergillus niger, Alternaria and Ulocladium were the most prevalent molds in all seasons. Overall, there was a seasonal trend in the amount of mold contamination with maximal contamination observed during autumn and winter seasons. Manuscript profile

  Mycotoxins in animal feed transfer to animal products and thus cause some problem like cancer in human. Contaminated feed must be omitted for prevention of toxin transfer. This study was designed for determination of aflatoxin B1 levels in poultry diet. A total of 177 samples were collected randomly from broiler feeds from different farms and tested by ELISA. Results showed %98.9 contamination of total sample. Levels of aflatoxin B1 in positive samples ranged from 0.64 to 88.5µg/kg and the average contamination level of samples was estimated at 9.91 µg/kg. In the levels higher than 10µg/kg (permitted for broiler diet) the highest rate belonged to complete feed (46.2%) and soybean meal (33.4%). The results indicated that samples take in summer had more contamination. The difference between this season with others was signifcant (p<0.05). High temperature in summer causes more fungi reproduction and hence more toxin production. The difference between corn, wheat, soybean, barley and complete diet samples was not signifcant (p>0.05).   Manuscript profile
