Mycotoxins in Aquaculture Feeds
Mycotoxins are toxic chemicals produced by certain species of molds usually belonging to the Aspergillus, Penicillium or Fusarium genera. The importance of mycotoxins to aquaculture and animal agriculture first became apparent during the early 1960s with outbreaks of aflatoxicosis in young turkeys in the United Kingdom and hatchery-reared rainbow trout (Onchorynchus mykiss) in the United States...
متن کاملRelationships among resistances to fusarium and Aspergillus ear rots and contamination by fumonisin and aflatoxin in maize.
ABSTRACT Fusarium verticillioides, F. proliferatum, and Aspergillus flavus cause ear rots of maize and contaminate the grain with mycotoxins (fumonisin or aflatoxin). The objective of this study was to investigate the relationships between resistance to Fusarium and Aspergillus ear rots and fumonisin and aflatoxin contamination. Based on a previous study of 143 recombinant inbred lines from the...
متن کاملThe 2009 Wisconsin Corn Crop High Moisture Corn, Aerobic Stability, Feed Additives and Mycotoxins Common Questions
Record low growing degree days and suboptimal growing conditions for corn in 2009 significantly delayed corn dry down and harvest in much of Wisconsin. As a result, near optimal environmental conditions (frost before full maturity) were present in the fall of 2009 for field mold growth. Field molds indentified on corn in the fall of 2009 by the University of Wisconsin Department of Plant Pathol...
متن کاملEvaluation of GEM Germplasm for Multiple Insect Resistance and Fumonisin Concentration
The Western corn rootworm (WCR) and the European corn borer (ECB) are serious pests of maize in the U.S. Secondary infections with Fusarium verticillioides, F. proliferatum, and F. subglutinans occur after ECB larvae feeding, causing ear rots and contamination with fumonisin, a mycotoxin associated with severe animal and human health disorders. The tolerance of maize germplasm adapted to the Mi...
متن کاملGEM Germplasm – Unlocking Maize Diversity for Improving Host Plant Resistance against West Corn Rootworm and Other Biotic Stresses
The Western corn rootworm (WCR) is a serious pest of maize in the U.S. and of growing importance in Europe. Soil insecticides, the use of transgenic maize hybrids producing a Bt toxin, and the rotation of maize with other crops are successfully used to manage WCR populations. However, the occurrence of WCR populations resistant to insecticides and adapted to cultural practices raises the questi...
