Abstract Mycotoxins are secondary metabolites produced by specific filamentous fungi that are common contaminants of agricultural commodities. These compounds are toxic to humans and animals, and they are a health problem worldwide. Mycotoxin-containing feeds can cause serious diseases in farm animals and substantial economic losses. Therefore, the objective of this study was to determine the occurrence and levels of six mycotoxins in three types of forage at retail in the state of Nuevo León, México. The hypothesis was that all types of forages were contaminated with at least one of the six mycotoxins analyzed. One hundred and twenty samples of alfalfa (Medicago sativa L.), sorghum [Sorghum bicolor (L.) Moench], and grass (Cenchrus ciliaris L.) used for... |

Studies were carried out to isolate microorganisms from corn and silage screened for their ability to inhibit F. moniliforme growth (strain 113F) in association with fumonisin detoxification. Among 150 isolates four Gram-positive bacilli and one yeast with inhibitory activity were selected. The inhibition zone ranged from 50 to 72.5 mm using cultures, and from 25 to 52.5mm for crude alcoholic extract. The isolates S9, S10, S69 (sporulated bacilli) and SE3071 (yeast) degraded 43, 48, 83 and 57% of the initial FB1 concentration, respectively. The pH increased gradually in the medium during incubation for biodegradation process. |

In this study a total of 16 Fusarium verticillioides strains isolated from corn feed samples were characterized by fumonisin (FB) production and random amplified polymorphic DNA (RAPD). All the strains produced FB1 and FB2 with levels ranging from 2.41 to 3996.36 µg/g, and from 1.18 to 1209.91 µg/g, respectively. From the 16 F. verticillioides strains, four were identified as low (3.59 to 1289.84 µg/g), eight as intermediate (>1289.84 to 3772.44 µg/g) and four strains as high (>3772.44 µg/g) fumonisin producers. From the total of 105 loci amplified, 60 (57.14%) were polymorphic. RAPD analysis showed very similar patterns among low, moderate and high fumonisin-producing strains. Although RAPD markers were capable of discriminating the different F.... |

Abstract: The objective of this work was to determine the correlation of the physical attributes of corn and the mycotoxins present in its grains with the severity of tongue lesions in broiler breeder roosters. The occurrence of the aflatoxin, vomitoxin, zearalenone, T-2 toxin, and fumonisin mycotoxins was detected in the corn grains used in the feed formulation for breeder chickens. The percentages of moisture and broken grains were positively correlated (Pearson’s correlation) with the presence of aflatoxin. Milder lesions (grade 1) are positively correlated with aflatoxin and negatively correlated with fumonisin, and the most severe lesions (grade 3) are positively correlated with vomitoxin, fumonisin, and T-2 toxin. |

The effects of aflatoxin and fumonisin and their combination on egg production and quality, as well as the efficacy of a mycotoxin adsorbent in reducing or eliminating these effects in commercial layers. A number of 168 layers with initial age of 37 weeks were submitted to an experimental period of 56 days. A completely randomized experimental design in a 3x2+1 factorial arrangement was applied (3 treatments with mycotoxins: aflatoxin (AF), fumonisin (FU), or aflatoxin + fumonisin (AF+FU); 2 treatments with or without adsorbent; and a control group that was fed no mycotoxins, nor adsorbent), totaling 7 treatments with 6 replicated of 4 birds/cage. The dietary inclusion levels were 1ppm AF, 25ppm FU, and 2 kg adsorbent/ton feed. Birds fed AF presented the... |
