Feed and malt
”Effective feeds, healthy animals” is a good description of Raisio Feed’s operations. Raisio Feed aims to be a safe partner, offering livestock producers pure and competitive feed mixes and professional service for the planning of feeding.
Feeds and feeding methods shall improve the financial performance of farms and the wise and effective completion of their own feeds, as well as reduce environmental emissions.
Raisio Malt produces and markets high-quality brewing malts for both the domestic and export markets. Raisio Malt’s strengths are its expertise in high-quality northern malting barley, its control of logistics and its knowledge of the markets.

Case: Fish feeds
|
The environmental impact of fish farming has seen a considerable decrease in the past decade. The development of feed mixes has clearly reduced the load on water systems.
The main nutrients carried from fish feeds into the water system include nitrogen, which results from the decomposition of proteins (aminoacids) in feeds, and phosphorus, contained in the fish meal used for feeds.
Reducing phosphorus and nitrogen content
A variety of plant-based protein sources have been identified as alternatives for fish meal. This has lowered the overall phosphorus contents in fish feeds by some 30% in the past decade.
The phosphorus requirement for salmon is 5–8 grams of biologically usable phosphorus per each kilogram of weight. As a result of a reduction in the overall phosphorus content and the development seen in feeding, the fish nowadays utilise nearly all of the usable phosphorus in feeds.

The optimised amounts of aminoacids have enabled a reduction in the overall protein content of feeds, which has decreased their nitrogen content by 15–20% in the past decade.
Reforms reducing the environmental impacts of Raisio’s fish feeds

1992: First high-energy feed in Finland (crude fat level 30%)
|
|
|
1993: Finland’s first low-phosphorus feed (phosphorus content
0.8%)
|
|
|
1997: Considerable improvement in the efficiency of feed (crude fat level 33%)
|
|
|
1997: Launch of low-nitrogen feeds with optimised aminoacids
|
|
|
2002: Further improvement in the efficiency of feed (crude fat level 35%)
|
