Protein Limit: Technical Notice Reminder Regarding Concentrate Crude Protein Limit

Irish farmers dealing with difficult grazing conditions have been given an important reminder on the seasonal protein rules for cattle feed. In this latest gov.ie update, the Department of Agriculture, Food and the Marine has clarified how the concentrate crude protein limit should be applied during a period of weather-related pressure on grass growth across many parts of Ireland.

The notice, published on 21 July 2026, is especially relevant for farmers, feed mills and advisors managing herds during the main grazing season. While the 14% concentrate crude protein limit remains part of the Good Agricultural Practice for the Protection of Waters Regulations, the Department has stressed that practical flexibility exists where animal nutrition and welfare require it.

gov.ie update on concentrate crude protein limit

Under the current rules, the 14% crude protein cap applies from 15 April to 30 September for concentrates fed to dairy cows and other cattle over two years of age while they are fully outdoors at grass. The policy is designed to reduce nitrogen surpluses during the grazing season, when high-quality grass is generally expected to meet much of the animals’ protein needs.

However, the Department of Agriculture, Food and the Marine has acknowledged that recent weather patterns have affected grass growth, potentially changing the nutritional balance available on farms. In those cases, the gov.ie notice makes clear that animal welfare and proper dietary management remain the priority.

• The 14% limit applies only to eligible cattle at grass full-time
• The rule does not apply where animals are not outdoors full-time
• Higher crude protein feed can still be used where justified
• Written confirmation is required to support that decision

When higher protein feed is allowed

The gov.ie reminder states that where cattle need a higher crude protein level to maintain health, performance or welfare, the Department will continue to allow this. Farmers can rely on written confirmation from one of the following:

1. The feed supplier
2. A recognised ruminant nutritionist
3. An accredited Farm Advisory Service advisor

This is an important point for those working with advisors, agri-consultants and feed providers, particularly during periods when grass quality is inconsistent. It also aligns with broader agricultural oversight across Irish public bodies, including how compliance and farm records may be reviewed alongside standards often associated with regulators and agencies such as the Revenue Commissioners, CSO and Environmental Protection Agency (EPA), where record accuracy matters.

Record-keeping requirements farmers should not ignore

From a compliance perspective, the date feed was purchased is a key factor in assessing whether the rules have been followed. Farmers are also expected to keep clear records showing:

• Types of concentrate feed purchased
• Quantities fed to livestock
• Crude protein content of the feed
• Relevant purchase dates

Under SI No 588/2025, as amended, these records must be kept for five years and produced for inspection if requested. For farmers navigating Agriculture, Food and environmental rules through gov.ie, this is a practical step that can help avoid unnecessary compliance issues.

What this gov.ie notice means for Irish farmers

The key takeaway from this gov.ie technical notice is that the concentrate crude protein limit still applies, but it is not intended to undermine animal welfare or sensible feeding decisions. Farmers, advisors and feed mills should continue to work together to ensure cattle receive an appropriate diet while also meeting environmental obligations set by the Department of Agriculture, Food and the Marine.

As weather conditions continue to affect farming decisions, this gov.ie reminder offers both regulatory clarity and practical reassurance: follow the 14% rule where it applies, document any exceptions properly, and keep full records to stay compliant.
