1. Introduction Aflatoxins (AFs) are secondary metabolites of the Aspergillus species of fungi, which are generally contaminate tropical and subtropical food and feedstuffs [1]. However, due to climate change, their occurrence in temperate climates should be taken into account not only during storage but also on the field [2,3]. Climate change usually causes drought stress in fungi, and stress-re ...

1. Introduction Ochratoxin A (OTA) is a secondary metabolite of certain species of the Aspergillus and Penicillium genus [1]. The chemical structure of OTA consists of weak organic acids with a dihydroisocumarin moiety joined by a peptide bond to 1-phenylalanine [2]. There are three ochratoxin forms, designated as A, B and C, which have slight structural differences; however, ochratoxin A (OTA) i ...

Introduction The global aquaculture production of food fish has increased tremendously over the last decade, reaching 62.7 million metric tonnes in 2011 or about 40.1% of world total fish production [1]. Asian seabass (Lates calcarifer) or barramundi is an important aquaculture species native to the Indo-West Pacific region [2] with increasing production currently estimated at 67,000 tonnes [3]. ...

Ingredients used in animal feeds and their contamination with undesirable substances, such as mycotoxins, are fundamentally important both in terms of the quality of animal products and the potential human health impacts associated with the animal-based food production chain. Feed ingredients contaminated with mycotoxins may have a wide range of toxicological effects on animals. Therefore, mycotox ...

Introduction Feed supply is important for animal production and any factor that affects the security of the feed supply is a significant constraint to production. Feed spoilage by moulds may result in heating, reduced palatability and the loss of nutritive value (Christensen, 1974). In addition, the affected commodity may become contaminated with mycotoxins. The biological reactions following ing ...

Your comments are really interesting and important. First is about the synergistic or antagonistic effects of different mycotoxins. For instance some other mycotoxins have measurable effect on aflatoxins, but these interactions in vivo conditions is not yeat clear, and usually underestimated, and the in vitro data is not suitable for extrapolation to in vivo system. Determination of the real mycot ...

The question of Hafiz: What are the naturally occuring toxin binders?.... is really interesting and probably important. (1) Most of the mycotoxin binders are naturally occuring molecules/crystals. E.g. zeolite, glucomannans etc. (2) Some of the feedingstuffs, e.g. straw or hay also have mycotoxin binding capacity.

Re: Olayinka Thank you for the comment. DON tolerance of chicken (and most of the poultry species) is an unsolved problem. In the article we discuss about one of the potential background of that tolerance. We speculate that, as in all farm animals, gut microflora has potential to detoxify xenobiotics, such as DON, and the tolerance probably based on the different capacity of the microflora. Ageing ...

Re: Dennis Tranquil Thank you for the comment, such level of DON (1.5 mg/kg feed) contamination did not cause measurable effect on proudction traits, but even at this level it may cause some effect on the biological defense system. For this reason in the case of deficiencies of antioxidants in the diet it may cause effect also on performance parameters.
