Background/ Objectives: Aflatoxin B1, a potent carcinogen is produced by Aspergillus flavus Link ex Fries. Natural contamination of aflatoxin in Bihar is fairly high due to socio-economic backwardness and also outdated agricultural and storages practices. Methods/ Statistical analysis: In the present investigation cattle feeds collected in different seasons (Winter, Summer and Monsoon) from three different localities (Bhagalpur, Banka and Naugachia) were screened for aflatoxin B1. Analysis of Variance has been done with the help of Microsoft Excel, 2013 (USA). CD has been calculated at 5%. Findings: The amount of aflatoxin B1 was significantly high (P<0.05%) in household cattle feeds followed by commercial cattle feeds, where the mean value of AFB1 was 5.02 ± 2.46µg/kg and 4.19 ± 1.05µg/kg, respectively. Freshly harvested cattle feeds (maize, paddy husk, paddy straw, maize straw and green grasses) were comparatively safe. Seasons had marked influence on aflatoxin B1 contamination on various types of cattle feeds. Maximum levels of aflatoxin B1 was detected during wet seasons in household cattle feeds (Mean value = 7.79 ± 2.07µg/kg). Maize grains because of high nutritional value and production, it is one of the major ingredients of cattle feeds. In the locality of Naugachia, flood and frequent rains delay the natural drying of maize kernels during harvesting in monsoons resulting thereby, high mould infestation and aflatoxin synthesis. Novelty/ Applications: In order to check the risk of aflatoxin M1 toxin entrance in food chain and subsequent human/ cattle health and economic losses, frequent evaluation of AFB1 in cattle feeds be monitored.
