title: Estimation of ochratoxin A in poultry feed and its ingredients with special reference to temperature conditions.
abstract: 1. The present study was designed to analyse ochratoxin A (OTA) in poultry feed samples (mixed types) along with different poultry feed ingredients collected from different farms and market of Lahore, Pakistan. 2. The whole year (2012-2013) was divided into three sub-periods depending upon environmental conditions, that is, July-October (hot and humid), November-February (winter) and March-June (moderate). During each sub-period 120 samples were collected for each feed and each ingredient constituting a total of 840 samples (120x7 of feed and feed ingredients in each sub-period). 3. The results of this study indicated that the incidence of OTA-positive samples was highest in July-October followed by that during March-June while the incidence was minimum during November-February. Similarly, the largest number of samples was below the maximum tolerable level (MTL) during November-February followed by March-June while the least number of samples was below MTL during hot weather (July-October). 4. This is the first elaborative study regarding the levels of OTA in poultry feed and its ingredients collected from Lahore, Pakistan.
