Ochratoxin A (OTA) is a mycotoxin produced mainly by Aspergillus ochraceus and Penicillium verrucosum. The family of ochratoxins consists of 3 members, viz. ochratoxin A, B and C but ochratoxin A is the most toxic one (Chang et al. 1979). They are the second major group of mycotoxins characterized after the discovery of aflatoxins. OTA is an isocumarin derivative linked through the carboxy group t ...

INTRODUCTION The worldwide occurrence of mycotoxins producing fungi and their ability to grow on the variety of economical important cereal crops have rendered them as unavoidable contaminants of human and animal food and feeds. The family of ochratoxins consists of three members known as ochratoxin A, ochratoxin B and ochratoxin C among these ochratoxin A (OTA) is the most toxic one. They are th ...

The presence of ochratoxin A in poultry feed causes significantly to health disorders and decreases production. In a survey conducted to investigate global occurrence of mycotoxins, the incidence of OTA in South Asia was found to be 55% on analyzing the feed samples (Nahrer and Kovalsky 2014). Ochratoxin A causes significant losses and reduction in the profitability of poultry industry due to its ...

Various environmental stressors such as high ambient temperature and relative humidity influence the performance of broilers by reducing feed intake, feed conversion efficiency and hypophyseal-adrenocortical axis that in turn stimulates corticosterone which retarded growth (Dong et al., 2007). Reactive oxygen species (ROS) are generated at cellular level during normal bodily functions; however, hi ...

INTRODUCTION Aflatoxins, the natural contaminants of feedstuffs, are toxic metabolites produced primarily by Aspergillus flavus and Aspergillus parasiticus. Aflatoxins may cause serious economic losses in the poultry industry because they prevent birds from achieving optimum body weight gains (Khatke et al., 2012; Oguz and Kurtoglu, 2000) Small amounts of aflatoxin B1 may cause reduction in econo ...

INTRODUCTION There is increasing evidence that cereal grains used for poultry feed are commonly contaminated with mycotoxins. Mycotoxins are toxic compounds produced by fungi, when present in the feed depress nutrient quality of the feed and hence the health and performance of poultry. The tropical and subtropical climate with hot and humid condition prevailing in India coupled with poor har ...

Presence of mycotoxins in feed is one of the major constraints in maintain feed quality because the mycotoxins are widely present in feedstuffs around the world and may affect production even in very low concentration. The most widespread and in most studied group of mycotoxins, aflatoxins are of great concern in warm and humid climatic conditions like India (Singh et al. 2010). Aflatoxin in poult ...

INTRODUCTION Aflatoxins belong to a group of mycotoxins produced as secondary metabolites by fungi of the Aspergillus genus, especially A. flavus, A. parasiticus and A. nomius (Kurtzman et al., 1987). No region of world escapes the problem of mycotoxins and according to Lawler and Lynch (2005) mycotoxin are estimated to affect as much as 20% of world’s crop each year. Crops grown under ...
