中文摘要：本研究探索了成品肉鸡饲料中黄曲霉(A. flavus)的存在并分离了黄曲霉毒素产毒菌株。结果表明需要对复合型商业饲料进行普通真菌学监测，以便针对这类污染制定控制措施，防止中毒综合征。
外文摘要：Occurrence of Aspergillus flavus (A. flavus) in finished commercial broiler feed and among the isolated strains of A.flavus having capacity to produce aflatoxin was investigated in this study. Finished commercial broiler feed samples (n=96) were collected from broiler chicken farms in and around Quetta district. Physical properties i.e. moisture and pH were determined by oven drying and pH meter, respectively. Viable fungal count of the feed samples was estimated by using spread plate technique. Identification of fungal isolates was carried out on the basis of cultural and morphological characters by using slide culture technique. While mean moisture percentage was recorded as 5.3% with a significant difference (P<0.05), the pH was noted to be slightly acidic with non-significant difference (P>0.05) among seasons. Overall mean viable fungal count was 4.72 x 10(3)+/- 708 with a significant association (P<0.05) among seasons. Out comes from study showed that, 44.8% of the assayed samples were contaminated with A. flavus. From them, 48.8% of isolates were capable of producing aflatoxin B-1. The study revealed the need of regular mycological monitoring of compound commercial feed in order to make control strategies and prevent toxic syndromes to this type of contamination.
