INTRODUCTION It has been previously reported that severe contamination of grain and feed with zearalenone (ZEA) occurs in numerous areas of the world (Chaytor et al., 2011). The laggard harvest conditions of grain and the processing of edible oil significantly aggravated the contamination by fusarium in China, and the contamination levels of mycotoxins such as ZEA were much higher than those in other countries (Zhang et al., 1997). Pigs are the most sensitive species to...

1. Introduction Mycotoxins are a class of low molecular weight compounds that are produced by toxigenic strains of moulds that infect food and feed commodities. They can cause serious animal health related problems as they may be hepatotoxic, nephrotoxic [1,2] and may impair immune responses resulting in increased risk to secondary infection [3]. In addition, these toxins also compromise animal performance arising from...

Introduction Deoxynivalenol (DON), also known as vomitoxin, is a mycotoxin commonly found in wheat, corn, and other cereal grains. During wet, cool periods of the growing season, Fusarium graminearum forms a head blight, producing DON as a secondary metabolite. Because DON occurs frequently and at toxicologically relevant concentrations and pigs are the most susceptible...

With the goal of providing information and training on grain handling and storage safety, Iowa State University Extension and Outreach has produced a series of online learning modules. Developed through the Iowa Grain Quality Initiative, the no-cost learning modules can be used to train employees on current best practices.
A wide variety of issues are examined in the series, including: drying, aeration, grain storage, mycotoxins, processing, rendering,...

The presence of zearalenone in feed is unavoidable and zearalenone toxicosis is hard to treat. The most practical way to treat zearalenone toxicosis is to use an enterosorbent to prevent the initial dietary absorption by the gut and subsequent conjugated zearalenone compounds from being reabsorbed via enterohepatic circulation. Due to its rapid absorption in the small intestine, the inactivation of zearalenone after ingestion becomes extremely critical in...

Pancosma & Associates released its annual mycotoxin survey, in partnership with Labocea, covering 1740 raw material and animal feed samples, evaluating the risk posed to livestock animals by 46 different mycotoxins, mainly in Europe. The comprehensive analysis extended beyond simply detecting contamination, to take into account the differing levels of sensitivity across various animal species. The data gathered show large variations in levels of mycotoxin...

INTRODUCTION The presence of DON contamination in grain is directly related to the presence of head or ear blight produced by Fusarium fungi, which in turn is directly related to the moisture content at flowering and/ or harvest. Possibly due to recent high stress growing seasons, we have seen an increase in the presence of DON contaminated grains in the Prairie Provinces, and it is expected that DON contamination will...

Fumonisins—mycotoxins produced by several Fusarium species, especially Fusarium verticillioides (F. moniliforme) and proliferatum—have been reported in animal foods and corn-based human foods from around the world (1,2). Fumonisins alter sphingolipid biosynthesis, induce hepatotoxicity, and elevate serum cholesterol concentration in all species studied. Other effects are species specific: pulmonary edema and...

Poultry, swine and dairy producers admit today that the presence of mycotoxins in the feed is one of the main factors affecting animal production. As a result of the higher prices of feed ingredients, their quality is getting worse, with some grains showing higher levels of mycotoxins. High contamination levels can also be found in distillers grains, an ingredient in increasing supply, originated from the use of corn in ethanol production in the US. Some producers consider that...

Introduction
Previous research has shown that dietary ZEA may reduce nutrient digestibility and increase oxidative stress in pigs; and that the use of Calibrin-Z (CAZ), thermally processed clay, can prevent the negative effects of ZEA. However, it is unknown what CAZ will do if pigs are already intoxicated with ZEA. Therefore, the objective of the present study was designed to answer: 1) can ZEA and CAZ effects be...

The objective of this study was to determine if the addition of the mycotoxin adsorbent Agrabond (a brand of Agranco) negated, lessened or postponed the effects of the mycotoxin zearalenone in swine feed, as well as determine the effect of all test diets on feed conversion. On Aug 5, 2005, female pigs were purchased locally and test evaluated by a veterinarian, who determined that the animals were in good health. The pigs were randomly placed into...
