I am currently working on...
Eubiotics, which are products that modulate gut microflora. These are a special focus of my research, and we’ve so far developed solutions based on organic acids, essential oil compounds and probiotics to help prevent health problems in farm animals. Different combinations of these – particularly organic acids and essential oil compounds – have shown high potential: Ultimately end-consumers of meat and eggs are more likely to accept this type of solution over the use of antibiotics.
The aspect of my work that excites and inspires me the most is...
Supplying a growing world population with animal-derived protein is an enormous challenge. We need to make animal production more efficient, but at the same time ensure high welfare standards for farmed animals and safeguard our biological resources. I’m interested in trying to identify alternative feed ingredients – such as tropical plants, or even protein obtained from insects – so that we can secure foods like corn, cereals and soybean for direct human consumption.
The breakthrough I would most like to see made in my field is...
A sustainable alternative to fish meal. Many fish that people prefer to eat (like salmon), are carnivorous and need fish meal as feed. Thus, the oceans are being overfished in order to produce enough fish meal, which in turn produces enough of the fish that consumers want. This is not a sustainable, long-term system. Finding ways to feed and produce “vegetarian” salmonid fish – using purely raw vegetable materials – would be a big step forward in terms of our ability to supply future generations with high-quality animal protein.
