Abstract :

In this study, presence and amount of ochratoxin A were researched in mixed feed and barley samples used by beef cattle enterprises in Sivas district.In this research, 39 mixed feed and 32 barley samples were received separately from the establishments in December, February and April, and ochratoxin A analyses were conducted through the spectrophotometric method complying with the protocols defined in the test kit. In feeds of beef cattle, ochratoxin A levels were respectively discovered as 0.025, 0.024 and 0.024 ppm on average according to the periods of December, February and April. No significant difference was found between the ochratoxin A levels according to months. In barley, ochratoxin A levels were respectively discovered as 0.022, 0.020 and 0.021 ppm on average according to the periods of December, February and April. No significant difference was found between the periods. The ochratoxin A levels of mixed feeds were found higher than barley within the same period in December, February and April; significant difference was observed.Consequently, a certain level of ochratoxin A was discovered in the mixed feed and barley samples used in the beef cattle enterprises in Sivas. It has been agreed that it is necessary to provide the appropriate conditions at each stage from the production to the consumption of the feeds and feed raw materials for human and animal health.
