Mycotoxins in poultry
Common mycotoxins associated with mycotoxicoses in poultry include aflatoxins, fumonisins, zearalenone, ochratoxins, and trichothecenes such as deoxynivalenol and T-2 toxins. Diagnosis requires detection and quantification of the specific mycotoxin. Treatment includes removal of the source of the mycotoxin and supportive care. Mold mitigation strategies can be used for prevention. Mycotoxicoses are diseases caused by the poisonous effects of the toxins produced by filamentous microfungi (ie, toxigenic molds). Hundreds of mycotoxins are known and can produce mild to severe toxic effects when they occur above levels of concern. The importance of mycotoxin problems in poultry is probably considerable yet difficult to measure. Chronic low levels of exposure to more than one type of mycotoxin appears to be a commonality, yet is less clinically evident.

INTRODUCTION Aflatoxin causes severe economic losses to the poultry industry. Aflatoxicosis that occurs from ingesting aflatoxins is characterized in broiler chickens by decreased feed intake and growth rate, poor feed utilization and mortality (Tedesco et al ., 2004; Bailey et al ., 2006; Shi et al ., 2006). Aflatoxicosis is also associated with changes in biochemical and haematological parameters (Denli et al ., 2004; Basmacioglu et...

Zearalenone is the most common prevalent mycotoxin found in feed and raw materials available in South Asian Region. Zearalenone (ZEN) at lower concentration highly impacts the Swine. However, ZEN at higher concentration or presence of more than one mycotoxin will have a great impact in poultry especially Breeders and Layers. Zearalenone Toxicology Grains infected with the fungus Fusarium graminearum and Fusarium. roseum are the...

INTRODUCTION
Aflatoxins are defined as difuranocyclopentanocumarines / difuranopentanolidocumarines this contains a dihydrofuran or a tetrahydrofuran ring. One of the most important effects of post harvest decays of fruits, vegetables and especially of seed and feed deterioration by fungi is the produce of mycotoxicoses. This is a disease of animals and humans following consumption of feeds and foods invaded by fungi that produce toxic substances called...

Introduction Aspergillosis is a fungal disease of all poultry species; infection by A. fumigatus may induce significant economic losses particularly in turkey production (1). Aspergillosis usually occurs in the respiratory system of chickens, turkeys, and less frequently in ducklings, pigeons, canaries, and geese (2). In poultry, Aspergillus fumigatus is considered to be the most pathogenic and the most frequent isolates from pathologic lesions (3,4). In nature, the fungal...

Introduction The Brazilian production of chicken meat has increased considerably and the country is now the world's third largest producer and leader in exports (RODRIGUES et al., 2014). The growing demand for animal protein stimulates a rapid expansion of production systems and increasing the stocking density, favoring the multiplication and spread of pathogens. Outdoor poultry breeding systems that enable lower population density and higher animal welfare does not exclude...

Crops can be contaminated with mycotoxins already on the field (pre-harvest) or during transport, storage or processing (post-harvest). A survey of mycotoxin contamination in Europe and Asia showed that deoxynivalenol (DON) and zearalenone (ZEN) are 2 of the most important mycotoxins in Europe based on occurrence and toxicity. Both toxins belong to the group of fusariotoxins produced by Fusarium species and often co-occur. ...

Mycotoxins are toxic secondary metabolites produced by fungi and are involved in the contamination of grains used in human and animal diets (Gimeno, 2012). When ingested in high amounts, mycotoxins can affect the health and performance of animals by decreasing their immune response and increasing their mortality rates (Murugesan et al., 2015). The most important mycotoxicoses in breeder chickens are caused by aflatoxin B1, ochratoxin A, T-2 toxin, and diacetoxyscirpenol (DAS), and...

INTRODUCTION Aflatoxins (AF) are toxic metabolites produced by fungi, such as Aspergillus flavus and Aspergillus parasiticus, and are considered to be the most harmful mycotoxins as they are highly toxic to animals and humans (Kaya, 1989; Hoerr, 2003). There are six different kinds of aflatoxins: B1, B2, G1, G2, M1, M2. Aflatoxin B1 (AFB1) is accepted as the most harmful, as well as most common metabolite in feeds and foods (Hatch, 1988). Aflatoxicosis in quails has been...

Introduction
Mycotoxins are metabolites produced by molds (fungi) that can infest crops pre-harvest and can continue to flourish under sub-optimal storage conditions. Grains with a high moisture content are particularly unstable and prone to mold proliferation and possible mycotoxin production. Excess rainfall at harvest and at key periods during the growing season can be a major promoter of mycotoxin contamination of feedstuffs. These are the same conditions...

Introduction Traditionally, the presence of mycotoxins capable of causing damage in animal production has been demonstrated by detecting certain levels in ingredients and / or rations. Since this technique has many limitations, histopathology has been used in many areas to demonstrate that these toxic agents are actually affecting the birds. Here we propose a practical approach to demonstrate their presence in comercial farms. By following this...
