Pig Farming in Ireland: High Output, High Costs, and a Sector Under Pressure

Introduction

Pig farming in Ireland doesn’t always get the same attention as dairy or beef, but in terms of intensity and output, it is one of the most specialised sectors in Irish agriculture.

It is also one of the most exposed, shaped by global markets, high input costs, and a system that leaves very little room to slow down.

A concentrated sector producing at scale

Pig farming in Ireland is relatively small in terms of farm numbers, but large in terms of output.

In 2023:

• There were 1,748,377 pigs recorded nationally.
• Spread across 1,468 farms with pigs.

That reflects a sector that is highly concentrated, with production focused in a smaller number of specialised units alongside a wider group of smaller holdings.

Production is continuous, with pigs moving through a structured system year-round. This is not seasonal farming, it operates at a steady pace regardless of external conditions.

Strong export focus

Irish pig farming is heavily reliant on export markets.

In 2024:

• Pigmeat exports were worth approximately €490 million.
• Export volumes reached around 200,000 tonnes.

This means the sector is directly tied to global demand, pricing, and market conditions. When international markets shift, Irish pig farmers feel it quickly.

Performance and efficiency are central

Efficiency is what underpins the sector. Recent performance data shows:

• 27.9 pigs produced per sow per year.
• 2.26 litters per sow per year.
• 14.94 pigs born alive per litter.

These figures reflect significant improvements over time and place Irish pig production among the more efficient systems internationally. But that efficiency comes with a trade-off, there is very little margin for error.

Small changes in performance or cost can have a large impact on overall output and profitability.

A system shaped by scale

Pig farming in Ireland operates at scale.

Performance data from monitored herds shows an average of over 800 sows per farm, with some operations running well beyond that level.

Across the country, production is also geographically concentrated, with counties such as Cavan, Cork and Tipperary accounting for a significant share of the national herd. This reflects the capital-intensive nature of the sector and the level of investment required to remain competitive.

Environmental pressure is increasing

Pig farming is also under growing environmental scrutiny.

Agriculture accounts for over 99% of ammonia emissions in Ireland, with pig production contributing a portion of that total. Managing slurry and nutrients is a key challenge, particularly where farms must rely on spreading agreements with other landowners.

At the same time, research estimates the water footprint of Irish pig production at 2,537 litres per kilogram of pork, highlighting both the scale and efficiency of the system.

A sector that cannot slow down

One of the defining features of pig farming is that it is continuous.

Unlike grass-based systems:

• Animals are housed,
• Production runs year-round.
• Output cannot easily be reduced or paused.

This means farmers cannot simply cut back when costs rise, The system keeps moving and so do the costs.

Exposure to volatility remains the biggest challenge

Pig farming is closely tied to external factors, particularly:

• Feed markets.
• Energy costs.
• Global demand.

When these shift, the impact is immediate. Recent years have shown how quickly conditions can change, and how exposed the sector is to sudden increases in input costs.

Even when prices recover, the underlying volatility remains.

Conclusion

Pig farming in Ireland is a highly efficient and productive system. But it is also tightly balanced. It depends on consistency, in performance, in costs, and in markets. And when that consistency is disrupted, the effects are felt quickly. Because in pig farming, there is very little distance between efficiency and exposure.
