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: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
