Animal diets and that ubiquitous DDGS
DI Ines Rodrigues is a Product Manager for Mycofixï¿½ Product Line at BIOMIN GmbH, Industriestrasse 21, 3130 Herzogenburg, Austria.
BIOMIN conducted a mycotoxin survey with 103 worldwide DDGS samples. The insights gained should be important for all players in the animal production industry.
The inclusion of DDGS - dried distillers grains with soluble, a by-product from bioethanol production - in animal diets has increased over the last few years. Rising prices for feedstuffs and feeds worldwide have demanded the development of successful and economical sources of energy and proteins in animal diets. DDGS seems to gather these characteristics. However, it should never be considered that the mycotoxin menace is eliminated by the fermentation processes occurring during bioethanol production. Mycotoxins are the toxic compounds produced by fungi during the growth and storage of agricultural products. Raw materials'contamination in terms of mycotoxins is carried-over and even augmented during bioethanol production. A DDGS survey has been initiated by BIOMIN.
In this study 103 samples from all over the world were tested for the most important mycotoxins affecting livestock production. 99% of DDGS samples tested positive for at least one mycotoxin. 96% of these samples have shown a simultaneous contamination of 2 or more mycotoxins. Only one sample (wheat DDGS) out of 103, tested negative for the analyzed mycotoxins. The alert is out!
Although DDGS may be seen as a practical solution for animal producers, enabling them to counteract the rising prices of feedstuffs and feed, the widespread carefree use of these products is still far from reality. DDGS are a dangerous source of mycotoxins which are toxic compounds with hazardous effects to animal health and productivity. Monitoring the mycotoxin content of DDGS prior to its inclusion in animals' diets is crucial to avoid the exposure of animals to the negative effects of mycotoxins. Counteracting mycotoxins' effects can be later on accomplished by adding mycotoxin deactivating products to the problematic feeds to ensure successful animal production.
