Introduction Aflatoxins (AF) are a major concern in poultry production and public health because of serious economic losses and health problems. AF contamination causes reduced feed quality and reduced animal efficiency either through poor conversion of nutrients or problems such as reproductive abnormalities. Aflatoxicosis in poultry also causes listlessness, anorexia with lowered growth rate, p ...

IntroductionMycotoxins are a large group of toxins produced by moulds and they can be very toxic for animals, plants and humans. Mycotoxins occur particularly in regions or countries with climates of high temperature and humidity or where there are poor crop harvesting and storage conditions, which encourage mould growth and mycotoxin development (25). The toxic effects of mycotoxins are mainly on ...

IntroductionAflatoxins (AF) are a major concern in poultry production and public health because of serious economic losses and health problems. AF in poultry feed cause listlessness, anorexia with lowered growth rate, poor feed utilization, decreased egg production and increased mortality (Miazzo et al 2000). Anaemia (Oguz et al 2000a), reduction of immune function (Gabal and Azzam 1998, Oguz et a ...

IntroductionMycotoxins are toxic metabolites that synthesized by a variety of fungal species and can be produced in feed, feedstuffs and foods in suitable conditions, such as moisture, temperature, oxygen and duration (Saleemi et al., 2017). The most common mycotoxin found in poultry feed and foodstuffs is aflatoxins (AFs) because it is produced rapidly and more toxic than the others (Oguz, 2016; ...

INTRODUCTION Aflatoxins (AF), a group of closely related, extremely toxic chemicals, are produced by Aspergillus flavus and Aspergillus parasiticus and can occur as natural contaminants of poultry foods (Edds and Bortell, 1983; Leeson et al., 1995). Aflatoxicosis is an important disease of livestock and poultry. AF may be produced in food and foodstuffs before harvest, between harvest and drying, ...

Originally published in Research in Veterinary Science 2001, 71, 59-66 AFLATOXINS (AF), are secondary metabolites produced by certain fungi belonging to the genus Aspergillus and can occur as natural contaminants of poultry feed (Leeson et al 1995, Oguz 1997). The toxicity of AF in broiler chickens has been widely investigated by the determination of their carcinogenic, mutagenic, terato ...

Originally published in Research in Veterinary Science 2000, 69, 89–93. AFLATOXINS (AF), a group of closely related, extremely toxic chemicals, are produced by Aspergillus flavus and Aspergillus parasiticus and can occur as natural contaminants of poultry foods. Aflatoxicosis is an important disease of livestock and poultry. The frequent AF contamination of agricultural commodities ...
