Amongst the most widespread mycotoxins, aflatoxins are of great concern in warm and humid climatic conditions like India (Singh et al. 2010). Aflatoxins include B1, B2, G1 and G2, and aflatoxin B1 (AFB1) is the most important toxic secondary metabolites, produced by 3 closely related species of Aspergillus; A. flavus, A. parasiticus and A. nomius in the feedstuffs. Avoidance of contaminated feed i ...

Mycotoxins are a group of structurally diverse secondary metabolites of fungi that occur as contaminants of grains worldwide. Aspergillus, Alternaria, Claviceps, Fusarium and Penicillium species of fungi are ubiquitous in nature and under ideal conditions often infect economically important crops during storage, shipment and processing. Many secondary metabolites produced by these fungi can cause ...

A number of cereals and other crops that are incorporated into the human and animal feed are susceptible to fungal attack and mycotoxin production, either in the field (before and after harvest) or during storage, transport, processing and feeding whenever conditions are favourable. The fungi involved produce highly toxic compounds as secondary metabolites referred to as mycotoxins, which can caus ...

INTRODUCTION Many mycotoxins can cause serious health problems in poultry and their presence in feedstuffs may result in a serious economic losses. 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). Crops contaminated with aflatoxins are a worldwide problem and ...

INTRODUCTION Presence of mycotoxins in feed is one of the major constraints in maintaining feed quality because the mycotoxins are widely present in feedstuffs around the world and may affect production even in very low concentration. These are low molecular weight toxic secondary metabolites produced by certain strains of filamentous fungi, which invade crops in the field, during harvesting ...

INTRODUCTION Presence of mycotoxins in feed is one of the major constraints in maintaining feed quality, especially in tropical countries. The Food and Agriculture Organization has estimated that 25% of the world’s crops are affected by mycotoxins each year (Das, 2004). The most widespread mycotoxin i.e., aflatoxins are of great concern in warm and humid climatic conditions like India (Sing ...

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 ...

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 ...

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 ...
