September milk supply figures released by the Central Statistics Office (CSO) show that year-to-date deliveries to Ireland’s dairy processors are tracking at similar levels to the record-breaking years of 2021 and 2022.

The milk intake between January and September is estimated to have hit 7.37bn litres.

This is a jump of 5.7% or an extra 400m litres of milk on the volumes reported for the same nine-month period in 2024.

They are also up 1.3% on 2023’s figures.

Milk deliveries for September rose by 7m litres in comparison with September 2024 to 774.7m litres, representing a 0.9% year-on-year increase or a lift of 1.4% when assessing against the same month in 2023.

Strong levels

Despite strong levels of milk supply growth on a year-to-date basis, September supplies did not exceed the levels recorded in 2021 or 2022.

Every month of 2025 bar February witnessed a strengthening of milk supplies relative to 2024’s levels.

The data shows that the pace of milk supply growth slowed somewhat into quarter three, but supplies still rose 3.7% when compared with the corresponding quarter of last year.

On milk constituents, the CSO reported that while fat content increased from 4.60% in September 2024 to 4.69% this September, protein slipped from 3.89% to 3.84%.

The CSO’s data also shows that over the past 50 years, processor milk intakes more than doubled from 310.8m litres to 774.7m litres.
