Following a long lasting 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 39 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 and advisory services and fish meal industry were represented.
Alfons Jansman from Wageningen Livestock Research, Holland, explained why it becomes increasingly important to ensure that requirements for ALL amino acids are met, while lowering the feed’s content of crude protein. Low feed intake, with reduced daily gain and poor feed conversion as a consequence, occurs when the piglet’s need for amino acids is not covered entirely. Alfons focused on a new aspect; being the total content of nitrogen in the diet. As a consequence of lowering the crude protein content in the diet, the nitrogen supply is limited as well, which might impair the forming of the non essential amino acids by the pig itself. Avoiding imbalance in the amino acid composition is crucial to good performance.
Sam Millet from ILVO, Institute for Agricultural and Fishery Research, Belgium, showed trial results that clearly confirm the requirement for tryptophan in growing pigs in Denmark; which is 20% relative to the lysine content (on SID level). Tryptophan is in particular important in relation to the immune system, feed intake and therefore, performance.
Nathalie Quiniou from IFIP, Institute for Porc Research, France, provided an update on the benefits of phase feeding in fattening pig production. Main benefits are lower feed costs and a reduction of excretion of nitrogen to the environment by 15% approximately. Phase feeding however, requires a very precise definition of the exact nutrient content in each diet; Nathalie underlines.
Irene Eising from Orffa Additives showed how new forms of copper, zinc and selenium differentiate themselves from the usual sources. The so-called “hydroxy-minerals” (copper and zinc) are characterized by a greater bioavailability. We saw results of a trial performed in a sow herd with 775 sows, where claw health was monitored during a year by scoring the claws in the farrowing crate. Hydroxy minerals in combination with Orffa’s new generation of organic selenium; Excential Selenium4000, gave a better claw health in the herd.
Marc Rovers from Orffa Additives presented our 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 cannot be stored in the bodytissue. Trials showed that the content of L-selenomethionine in a source of organic selenium, clearly determines the deposition of selenium in the body tissue. The more L-selenomethione in the product; the higher the selenium content in the tissue.
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.
