| O objetivo do presente trabalho foi estudar o efeito da fumonisina B1 (FB1) sobre o peso corpóreo e as vísceras (fígado, rim e coração) de codorna poedeira japonesa (Coturnix coturnix japonica), devido ao escasso dado toxicológico nesta espécie. Quatro grupos, sendo cada um constituído de 32 codornas de linhagem comercial, receberam ração contendo FB1 nas concentrações de 0 (controle), 10, 50 e 250mg kg-1, durante 28 dias. Observou-se uma redução (P<0,05) no peso corpóreo das aves submetidas ao tratamento 250mg kg-1 de FB1. Os pesos relativos do rim e do coração mantiveram-se semelhantes em todos os tratamentos (P>0,05), porém as aves do grupo 50 e 250mg kg-1 apresentaram aumento no peso relativo de fígado (P<0,05). Alterações histológicas foram... |

| Although fumonisin B1 (FB1) is a mycotoxin poorly studied in wheat, the Fusarium genus fungi have been frequently detected in this cereal, especially in subtropical regions such as southern Brazil, thus studies on their occurrence are required. This study evaluated the mycobiota, water activity and the presence of FB1 in 11 wheat cultivars grown in the northeastern and northwestern of Rio Grande do Sul. The mycobiota was identified by morphological and molecular techniques and FB1 was determined by liquid chromatography with fluorescence detection (HPLC-FL). Microbial counts lower than 103CFU were found in the samples, and the fungi genera Phoma, Cladosporium and Fusarium were the most frequent. Despite this, 54% of the samples were contaminated with FB1... |

| ABSTRACT: The aim of the present study was to assess the occurrence of aflatoxins (AFs) and fumonisins (FBs) in feed ingredients (corn and soybean meal) and finishing feed in a broiler operation system, as well was to evaluate their effect on the productivity of 20 batches of broilers produced and the histology status of broilers’ liver after slaughter. Corn samples presented the highest frequencies of AFs and FBs, at mean levels of 29.1 and 2,100µg/kg, respectively. Soybean samples presented mean levels of 1.5 and 70µg/kg for AFs and FBs, respectively. Batches of broilers receiving feed containing FB levels higher than 1,000µg/kg had lower weight gain and higher mortality rates, while those fed rations with AFs equal or above the limit of quantification... |
