Orffa Scandinavia Symposium

Following a longlasting tradition; Orffa Scandinavia A/S held its annual symposium focusing on the nutrition of pigs.

Hotel Legoland in Billund hosted Orffa’s annual symposium; which was aimed at the Scandinavian feed manufacturers, feed researchers and consultants on feed for pigs. A total of 34 participants from Denmark, Norway and Sweden used the day to increase their knowledge of the particular amino acid nutrition and mineral nutrition in the modern pig production. Also fur animal research, fish feed and fish meal industry were represented.

In the morning; amino acid nutrition was the topic. Focus this time was to make visible which enormous potential that lies in feeding the pigs more precise in accordance with their daily requirement of amino acids. Experiments showed that significant reductions in emissions of nitrogen and phosphorus to the environment can be achieved. Feed costs are reduced considerably and also in feed production savings are possible. Precision feeding requires significant investments in automation and hardware, for which the present economic climate in pig production does not leave a lot of space. However; it is very interesting to see what is technically possible to achieve, so we can create visions for the future pig production.

Candido Pomar from Agriculture and Agri-Food Canada, Sherbrooke, Canada showed how using advanced equipment could feed pigs throughout the growth period with exactly the amount of amino acids that constituted their daily needs; neither more nor less. And that’s at maintaining good production results. Analyses and calculations subsequently showed large reductions in emissions of nitrogen and phosphorus to the environment.

Paolo Trevisi from the University of Bologna, Italy, showed how much variation there can be between the pigs’ ability to convert feed effectively into growth. Furthermore, he showed how important especially the amino acids tryptophan and threonine are to pigs that are under a health burden. Tryptophan in particular in relation to the immune system and appetite; threonine in particular in relation to the immune system and intestinal health.

William Lambert from Ajinomoto Eurolysine, France provided an update on recent trials in amino acid nutrition for pigs. The experiments confirm in a high extent the norms for the requirements for amino acids used in Denmark today.
Irene Eising from Orffa Additives showed how new forms of copper and zinc differentiate themselves from the usual copper and zinc sources. The so-called “hydroxy-minerals” are characterized by a greater bioavailability. This is an important step in the reduction of emissions of zinc and copper to the environment, which came to public attention in the autumn on the occasion of Aarhus University report on the increasing content of copper and zinc in the Danish soils.

Marc Rovers from Orffa Additives presented the new generation organic selenium; Excential Selenium4000. Marc documented that only the L-selenomethionine molecule, can be built into the protein in the body; in the milk or the eggs. All other chemical forms of selenium are used in the animal’s daily production of selenium-containing enzymes, but can not be stored in the body. It is well known that selenium is essential for the immune system of humans and animals. Unlike other sources of organic selenium there is no variation in the content of L-selenomethionine in Excential Selenium4000.

The day proceeded in a good atmosphere with very interested and engaged participants, who listened intensely and asked several relevant questions to the lecturers. We look back on a successful symposium and a rewarding day.
