New trial lowers phosphorus in pig production

SEGES Danish Pig Research Centre, which is part of the Danish Agriculture and Food Council, has demonstrated in a new trial that it is possible to save on the allocation of phosphorus for finishers, with benefits for the environment.

In a new trial, SEGES Danish Pig Research Centre has found new methods for how Danish pig producers can reduce the use of phosphorus in pig feed. The finding offers both economic and environmental benefits.

The trial is just one of the many that focuses on innovation in the industry and shows that by adding a high dose of the enzyme phytase, the phosphorus allocation in feed can be reduced. Phytase is an enzyme that enables other substances in the feed to be better utilised. This means that pig producers can save on the allocation of the additives released by the phytase.

Pig producer Lasse Eriksen has found that his phosphorus allocation has reduced by 15 per cent. And pig producer Martin Andreasen has found that a higher dose of phytase may reduce the need for phosphorus.

"The carrot is that we can show that the amount of phosphorus emitted is less, which means that we are allowed to use more livestock manure on our fields. So, this is good for both pig producers and for the environment,” says Martin Andreasen.

The result of the trial has meant that the Danish pig industry has amended the standard for phosphorus allocation so that all pig producers can now benefit from the new knowledge – whether they mix their own feed or buy ready-mixed feed.
