Safer pig feeds without antibiotics

02.09.2003


The use of antibiotics in animal feeds may soon be banned in the European Union. Despite positive effects on pig health and growth, there are growing concerns about bacterial resistance to antibiotics. This includes the risk of cross-resistance, with bacteria developing resistance to antibiotics used in human medicine.



In response to these concerns EUREKA project ANTIBIOTICS IN FEED has developed safe and healthy piglet feeds which are free from antibiotics. Crucially the new feeds can be quickly and easily introduced into today’’s feed manufacturing practice.

“When leaving out antibiotics there is a proven risk of diminished health, such as more diarrhoea and losses of piglets so it was important to develop alternatives to antibiotics that can minimize these problems,” explains Dr Annemarie Dirkzwager of Dutch lead partner Institute of Animal Nutrition De Schothorst.


The partners worked both separately and together, testing a whole range of products with different mechanisms. They evaluated dietary additions and different feed compositions in order to better understand the processes taking place in the piglet’s gut after weaning.

In vitro testing was used to explain the workings of the piglet in vivo experiments at cell level, by testing the effects of different feed additives in a CaCo-2 system representing a human cancer colon cell line. This behaves like piglet enterocytes during their growth and development. The tests showed that some organic acids had a positive effect on growth and improved gut condition.

The major problem that the partners had to tackle in the in vivo experiments was to ensure that the piglet test results were comparable and consistent. “Each partner had different facilities to do experiments with piglets. Also, the handling of the piglets was different, for example the age they were weaned and whether the piglets were kept outdoors or indoors,” says Dirkzwager.

Dirkzwager found a EUREKA project to be “a good and safe way to start up cooperation with less known partners. Once you have worked together in a project you know the reliability of the partner and the kind of results he obtains. Then it is easier to start further projects.”

The project’s experiments developed methods to strengthen processes in the gut and overcome negative effects caused by the lack of antibiotics. These alternative additives and standards for maximum or minimum levels of raw materials and nutrients are being used by feed manufacturers, including the project partners, to create safe piglet feeds without antibiotics. They have also been adopted by farmers.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
