Irish creameries and pasteurisers took in 14.2% more milk in August 2015 than they did for the same month last year, figures from the Central Statistics Office (CSO) show.
Domestic milk intake for August is estimated at 694.6m litres, the figures show.
Comparing the August 2015 milk produce figures with those for August 2014 shows that total milk sold for human consumption increased by 11.3% to 43.6m litres.
Butter production was also up year-on-year by 8.1% to 18,900t, the figures show.
For the first eight months of 2015, domestic milk intake was up 9.2% on the corresponding period last year. So far this year, Irish creameries and pasteurisers have taken in 4,725.5 billion litres of milk.
EU milk deliveries
The latest EU figures show Ireland way out in front in terms of milk production this year.
Meanwhile, other Member States such as France and Italy have seen lower production so far this year.
For the short-term outlook, the Milk Market Observatory (MMO) says cumulative EU milk deliveries in 2015 were estimated to increase by 1.1%.
Milk production increases continue in Ireland, Hungary, Netherlands, Spain, Poland and the UK, while downward trends are expected in France and Germany.
Production would continue to increase in 2016 but by no more than 0.9%.
For 2015, increased milk production would translate into 1.3% more cheese (and a stock increase by 30,000t), 7.5% more SMP (and +25 000 t stocks) and 4% more butter (and +5 000t stocks).
EU milk production was up by 1.1% in the first seven months of the year, but by 2.8% in the first four months after milk quota expiry.
