Reminder regarding concentrate crude protein limit

In response to recent weather conditions, and the delayed full-time turnout of livestock in many parts of the country, the Department of Agriculture, Food and the Marine wishes to remind farmers, their advisors and feed mills regarding the flexibility that exists regarding the concentrate 14% crude protein limit applicable from 15 April to 30 September 2026 as set out in the Good Agricultural Practice for the Protection of Waters Regulations (SI No 588/2025, as amended).

This measure is in place to reduce nitrogen surpluses during the main grazing season when good quality grass provides adequate crude protein for adult cattle. However, the Department recognises the primary importance of animal’s receiving a balanced diet in line with their conditions.

The requirement to limit concentrate crude protein to a maximum of 14% on an “as fed basis” from 15 April to 30 September applies to all farmers feeding concentrates to dairy cows and other cattle aged over two years, at grass. From a practical implementation perspective, compliance is assessed taking into account the date the concentrate feed was purchased.

The Department wishes to remind people that the requirement does not apply where cattle are not outdoors fulltime at grass.

Even in situations where cattle are at grass fulltime, the Department has always, and will continue to allow for situations where a higher level of crude protein is required in concentrates to maintain animal welfare or to meet the animal’s dietary needs. In that scenario the Department continues to accept written confirmation from the feed supplier, a recognised ruminant nutritionist or an accredited Farm Advisory Service (FAS) advisor stating that a higher level of crude protein is required.

Records of purchased feed should include the quantities and types of concentrate feed, including crude protein content, fed to livestock on the holding. Under SI No 588/2025, as amended, these records should be maintained for five years and made available for inspection if requested.
