The Mycotoxins Contamination In Corn Silage from Dairy Farms in Mexico

C orn silage is the main forage available in the whole dairy cattle rations around the world; which can undergo a deterioration by the
presence of fungi mainly Aspergillussp, Penicilliumsp and Fusarium sp. and their mycotoxins, with the loss of their nutritional
value, commitment in health and animal production and public health. The aim of this study was to determine the presence of three
mycotoxins in corn silage from three dairy farms located in Central region in Mexico. A total of twelve samples of corn silage, were
collected. It was made a sampling at three levels of trench silo, upper, middle and edge was performed in duplicate. It was determined
the physical forage quality using the particle size and pH parameters. Mycotoxins multiple technique by Aflatoxins, OcratoxinA(OA)
and Zearalenone (ZEA) was used in thin layer (TLC) to determine the presence of mycotoxins. The physical quality results showed
variations in dry matter content, with a lost half 15.78%, particle size upper to 5 cm, and pH in a range of 5.2-5.9. The pH founded
it was ideal for the synthesis of mycotoxins, it was detected the simultaneous presence of type B aflatoxins (AFB1) and G (Aflatoxin
G1), OA and ZEA in the upper layer and edge of the horizontal silo (trench silo). It is concluded that corn silage from two farms don´t
fulfill the physical quality and that all contain multiple mycotoxins. It is recommended to monitor the toxicological quality corn silage
prior to administration to cattle.
