This issue devotes considerable space to the feeding of residues from bioethanol production. The low-cost feed DDGS makes particular demands of the ration design. After all, the protein-rich mass does not leave the works in such a uniform composition state as one would imagine. Accordingly, values from tables are inadequate if the dried stillage is to be upgraded to a proper ration.

» Tasks of Efsa
Independent authority as a result of food crises

In recent years the term Efsa has been mentioned repeatedly in lectures and publications, especially in connection with limit values in feedstuffs, or when one or the other new feedstuff was or was about to be introduced onto the European market. For many listeners and readers this has led to questions such as - what is Efsa? Who is behind it and what are its tasks? This article aims to explore and shed a little light on the tasks of Efsa.

» The correct handling of a microbiological screening method
Microbiological method for detecting antimicrobially active substances in feedstuffs - (VDLUFA Method 28.4.1)

The development of multi methods for analysing antibiotics should not be underestimated. Their non-uniform chemical structures and physical properties make it difficult to develop optimal extraction agents, uniform treatment steps and comprehensive detection methods and to package these in a single method regulation. The variety of feedstuff types, their often complex compositions and the matrix effects caused by this, as well as calls for ever lower detection limits, do not make the task any easier.

» Quantitative determination of probiotic feed additives
Comparing European methods (EN-Standards) with VDLUFA methods

During the last ten years the working group Feed Microbiology of VDLUFA Section VI has developed altogether six VDLUFA methods for quantitative detection of various probiotic feed additives that are highly accepted in Germany. The methods have all been validated for the matrices additive, mineral feedstuff, premix and compound feedstuff (in meal form and pelletised), including milk substitutes, in altogether 39 ring tests. They are published in the VDLUFA method book volume III, Chapter 28.2, and will appear in editorially revised version in the 8th supplement.

» Using by-products from bio-ethanol production
Meeting Lysine requirements of monogastric animals

In livestock production, feed cost contributes 50 to 70 per cent of production cost and the major cost components are energy and protein sources. Nowadays nutritionists are facing challenges in feed formulation since ingredient prices are increasing due to a tight supply-demand situation. Bio-fuel production competes increasingly with the use of cereals and oilseeds for food and feed production. On the other hand, increased bio-fuel production results in increased supply by-products such as dry distillers grains with solubles (DDGS) and canola meal that find their way into animal feed.

» Securing sustainability of feed production
Why the feed sector should be certified too

Global demand for agricultural raw materials and commodities is growing. In addition to greater demand for food and feed production, biomass is now one of the most important sources of renewable energies. Biomass is an important alternative to fossil fuels and nuclear energy for future power supplies.

» Can soy be sustainably produced ?
Reliability depends on certificates

As concern has risen about the impacts of soy production, sustainability has become a buzzword in the food and feed markets. Concerns that initially focused on the destruction of forests and other ecosystems for soy expansion have quickly expanded to social issues such as the displacement of smallholder farmers – as well as questions over genetically modified soy.
