Abstract

BACKGROUND: Unhygienic Poultry feedstuffs can lead to nutrient losses and have detrimental effect on poultry production and public health. OBJECTIVES: This study was to investigate the fungal contamination of Poultry feed and its ingredients in broiler farms in Torbat Heydarieh, Khorasan Razavi province, Iran. METHODS: A total of 240 Poultry feed samples comprising three different feeds were collected and examined using dilution plating technique. Preparations of all samples from successive dilutions were prepared, and then 0. 1 ml of each dilution was cultured on the surface of Potato Dextrose Agar supplemented with Chloramphenicol and incubated at 27 ° C for 7 days. Fungal colony counting was performed based on CFU/gr. The fungi were identified by gross and microscopic features. Statistical analysis of the data was done using SPSS software version 21. RESULTS: In examined samples, fungal contamination was detected in 205 samples (85/14 %) out of 240 samples. The corn (32/5%) was the most contaminated feed, followed by soybean (29/16%) and finished feed (23/75%). The predominant fungi isolated were Fusarium spp. (41/3 %), Penicillium spp. (37/9%), Cladosporium spp. (21. 3 %), Paecilomyces spp. (17. 1%), Aspergillus fumigatus (13/3 %), Aspergillus niger (12. 9%) and Yeast spp. (12. 9 %). Frequency of toxin-forming fungi was significantly higher than the non-toxin-forming fungi (p<0/001). The mean total count of fungi was estimated 2/9 × 105 CFU/gr. CONCLUSIONS: The findings of this research showed the high prevalence of fungal contamination as well as high frequency of toxin-forming fungi. Therefore, the feed raw materials are important vehicles for introduction of fungal organisms into Poultry feed and fungal growth reduces the nutritional value of feeds. A program should be considered in order to control, limit and delete the fungi from feeds.
