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.
1. Introduction The Food and Agriculture Organization of the United Nations (FAO) estimated that 25% of the cereal production is contaminated by mycotoxins [1]. Aflatoxin B 1 (AFB 1 )—the major secondary metabolite of Aspergillus flavus, A. parasiticus, and A. nomius—has adverse effects on humans and animals that result in health disorders and economic losses. To avoid these harmful effects, many physical, chemical, and biological decontamination...

Storage of high moisture feed is one of the major problems for production of aflatoxins. Storage of feed for a month with 13% moisture was not safe to prevent aflatoxin (AF) production. However, the production of AF at 13% moisture level can be completely inhibited by adding fumaric acid @ 0.20% or citric acid @ 0.45%. At 15 and 17% moisture level in feed, more than 0.50% of fumaric acid or citric acid is required for complete inhibition of biosynthesis of aflatoxins. Fumaric acid was more...

1. Introduction Deoxynivalenol (DON) is a secondary metabolite produced by Fusarium fungi. DON is the most widespread mycotoxin found in grains such as wheat, rye, barley, maize, oats, and their byproducts [1,2]. A recent survey, reported that DON is the most frequent contaminant of feedstuffs in Europe [3]. From 4311 samples evaluated, 63% were positive, with an average positive level of 0.6 mg/kg and a maximum of 40.7 mg/kg. For poultry feeding stuffs, the recommended maximum...

Several strategies can be adopted to control the growth and development of moulds, and hence reduce their effects on the quality of feeds and feed material, and on animal performance. An important strategy is an appropriate storage, whereby many of the problems can be alleviated if the feeds and feed material are stored in clean and well-ventilated silos. A second way of controlling moulds and any further accumulation of mycotoxins is the use of chemicals, such as mould inhibitors....

INTRODUCTION For feed chain stakeholders in an increasingly competitive marketplace, the bottom line can rise or fall with the contaminant levels in grain and other raw materials. The repercussions of feedstuffs that fail to meet the highest safety and quality standards can spread across the entire value chain, jeopardizing livestock health and the reputation and economic performance of multiple businesses and entire growing regions. Ultimately, toxic contaminants that slip...

Introduction Globally, the ever-increasing demand for protein consumption (via meat production) in a sustainable manner, requires further reduction of the overall production cost. Feed cost remains key to this. However, variability of raw material costs and the complex load of mycotoxins contamination continue to negatively impact productivity. On top of that, animal health and productivity are affected by a number of other stress...

Five key learnings have emerged since the launch of the RISE Platform that has relevance for animal producers across the globe. What is truly unique is that the blood spot analysis process is minimally invasive, easy to use and simple to send for analysis. Simply add up a drop of blood from five different individual animals from a population to a special card, let it dry, pop it in an envelope and send it to one of the independent labs for analysis.

Mycotoxins are metabolites produced by fungi that can be present in feed ingredients. They are of great concern because they reduce the nutritional value of the feed formula and have a negative impact on the health and performance of the livestock. In the case of Southeast Asia, the annual loss due to aflatoxins in Philippines, Indonesia and Thailand was estimated to be around $900 million dollars, of which $500 million of the costs were linked to the effects in human...

Contamination by Mycotoxins: Causing failures in the antibiotic-free production. Many poultry and livestock producers worldwide are making serious efforts to reduce or eliminate the use of antibiotic growth promoters (AGP) in their farms. Going AGP-free is a complex process that includes adjustments in farm management, biosafety and feed formulation, among others. The ultimate target of these changes is to improve and maintain gut health, which is the basis of AGP replacement....

The mycotoxin contamination of grain harvested in a single year can differ from the mycotoxin patterns and levels of previous years in the same climatic region. Therefore, buying the newly harvested grain is like a betting game for the producer of animal feeds who has to deal with unknown, 'on-fire' contamination. Our MycoMan range of services allows the risk from the raw materials to the animals to be identified.

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, poor feed utilization, decreased egg production and increased mortality....
