Domestic milk intake by milk processors and co-ops was estimated at 760.4 million litres in September 2026, a decrease of 12.8 million litres or 1.7% when compared with September 2025, according to figures released today by the Central Statistics Office.
Key figures
- Domestic milk intake in September 2026 stood at 760.4 million litres, down 12.8 million litres or 1.7% compared with September 2025
- Fat content rose to 4.81% in September 2026, up from 4.69% in September 2025
- Butter production decreased from 30,100 tonnes in September 2025 to 28,600 tonnes in September 2026
- Quarter 3 2026 domestic milk intake was estimated at 2.61 billion litres, down 109.5 million litres or 4.0% when compared with Q3 2025
- Year to date intake from January to September 2026 was 7.2 billion litres, a reduction of 172.1 million litres or 2.3% compared with the same period in 2025
- Protein content increased slightly from 3.84% in September 2025 to 3.85% in September 2026
Quarterly and annual trends
The decline in milk intake affects the broader economy, particularly Ireland’s dairy processing sector. When compared with Q3 2024, domestic milk intake in Q3 2026 was down 13.8 million litres or 0.5%. Quarterly butter production decreased by 5,100 tonnes, from 93,100 tonnes in Q3 2025 to 87,900 tonnes in Q3 2026.
The year to date figures show domestic milk intake of 7.2 billion litres from January to September 2026, representing a reduction of 172.1 million litres or 2.3% when compared with the same period in 2025. This consistent downward trend across monthly, quarterly and year to date comparisons indicates sustained pressure on milk supply.
Product breakdown and quality metrics
Butter production saw a decrease of 1,500 tonnes, falling from 30,100 tonnes in September 2025 to 28,600 tonnes in September 2026. Total milk sold for human consumption reached 44.7 million litres in September 2026. Whole milk sales stood at 30.9 million litres, while skimmed and semi-skimmed milk sales were recorded at 13.8 million litres for the month.
Quality indicators showed modest improvements. Fat content increased to 4.81% in September 2026 from 4.69% in September 2025, while protein content rose slightly from 3.84% to 3.85% over the same period.
Considerations for Irish dairy businesses
The reduction in domestic milk intake may prompt processors and co-ops to consider capacity utilisation and production planning. Lower butter production volumes could affect output targets and processing schedules at dairy facilities across the country. Businesses involved in dairy supply chains, from farmers to distributors, may need to factor these intake levels into their operational planning.
The improved fat and protein content levels could offer some quality advantages for processors, though this must be weighed against the overall volume decline. The year to date reduction of 2.3% suggests these patterns may continue to influence the sector’s performance through the remainder of 2026.
