Amino acid nutrition, low protein diets and new sources of trace elements for animal nutrition. These were the main topics on the Orffa Scandinavian symposium 2015. Latest insights in research and new product developments were discussed during this full day symposium, organised by Orffa traditionally at the beginning of the year. The 2015 edition took place on Wednesday January 15th in Billund, Denmark and was attended by participants from Norway, Sweden en Denmark.
Amino acid nutrition in pigs
The morning session focused on amino acid nutrition in pigs. First presentation of was given by Anna Wessels, PhD student at Martin-Luther-Universität Halle-Wittenberg, Germany. Who gave a very detailed and informative insight in her PhD project on amino acid nutrition in piglets. Lowering CP levels in piglet diets is becoming common practice these days. A lower CP level is beneficial for gut health of the piglets, gives less environmental pollution and can save feed costs. When low CP diets are used it is very important to know the exact requirement of each individual amino acid. The requirement of next limiting amino acids and interactions between amino acids were discussed in this very interesting presentation.
Low CP diets for growing pigs
The next two speakers discussed about low CP diets for growing pigs. First Dr. Francesc Molist from Schothorst Feed Research in The Netherlands discussed the possibilities to lower CP levels in growing pigs. Technical results of low CP diets are in line with high CP diets, as long as the requirement for all amino acids are covered. Low CP diets require less usage of protein feed stuffs like soybean meal. This leads to lower feed costs, a higher nitrogen efficiency and lower environmental impact. This environmental effect of low CP diets was very nicely discussed in the following presentation by Dr.Florence Garcia-Launay from INRA in France, who showed that the choice of raw materials and diet composition has a significant effect on CO2 footprint. Lower CP diets and precise nutrition with multiphase systems can be a good strategy to lower the environmental impact of pig nutrition.

Trace element nutrition
In the afternoon session, the focus switched to trace element nutrition. Dr. Detlef Kampf from Orffa Additives discussed the latest insights around the trace element copper in piglet nutrition. Kampf showed the benefits of a new source of copper, hydroxy copper (Intellibond C) compared to copper sulphate for piglets.

Last talk of the day was given by Marc Rovers, also from Orffa Additives, who introduced a new form of organic selenium. This new generation of organic selenium (Excential Selenium4000) has all its selenium in 100% effective organic form. The superior effects of this new generation of organic selenium were demonstrated with several trials and discussed in detail with the audience.
