Searching for a pig farm for sale in Mayenne takes you into a livestock department where pigs have long sat beside dairy and beef. The sites on offer range from a finishing unit complementing a dairy herd to a self-contained farrow-to-finish business with its own farrowing house, weaner rooms and spreading area. Rural agencies, local notaries and farmers arranging their departure post these listings, giving capacity, how the animals are housed, the age of the buildings and the producer group the unit belongs to. All of them join our national selection of pig farms for sale.
This page adds the background the listings rarely carry: local land values, how the department divides between the northern bocage and the Craon country, what to look at in a pig house before investing in it and which authorisations to verify. To shape a setting-up project, our white paper « Créer une exploitation agricole » (in French) provides the method.
Land value drives much of the asking price for a pig farm. French tax transfer statistics (DVF, vineyards excluded) show, for 2025, a median of €6,059/ha in Mayenne (53), an average of €6,502/ha and 343 sales; 80% of transactions settle between €4,600 and €9,000/ha, against a national median of €5,307/ha.
The SAFER benchmark is not compiled at this scale; use the national figures instead, €6,460/ha for vacant land and pasture and €5,350/ha for let land.
The price of such a site is formed away from the hectares: in the condition of the rooms and how far they are automated, in effluent storage volume, in the operating authorisation, in the spreading area secured, in the worth of the herd and in the contract organising collection. Position parcel values with our land price observatory, then test whether your structure holds together using our financial calculators.
Many units here were designed at a modest scale and then enlarged: a refurbished farrowing house, insulated weaner rooms, slatted finishing rooms added over the years. A viewing starts with the structure and insulation, moves on to ventilation and its control, heating for young stock, the feed distribution system, the state of floors and pens, then the under-slat pits and the slurry store. Check that the storage works are covered, look at the loading bay, the entry room and whether an on-farm feed mill draws on cereals grown on the holding itself.
The herd is valued on its own terms: sow numbers, the genetics chosen, health status and how regular the batches are. Where the unit belongs to a wider property with a dwelling, pasture and cattle buildings, ask for each element to be costed separately; the pig facility, the land, the machinery and the animals depreciate quite differently, and lenders expect that breakdown before they will look calmly at a takeover file. Feed and grain inventories present on completion day are recorded in a jointly agreed schedule.
The north of the department, between Ernée, Gorron, Landivy and Mayenne, blends bocage, grass and indoor livestock: this is where many holdings combine pigs with dairying, on land that is still affordable. The south, around Château-Gontier, Craon and Renazé, holds larger farms, a long livestock tradition and a useful closeness to the slaughtering and processing facilities of western France. The eastern side, towards Évron, Villaines-la-Juhel and the Coëvrons, mixes cropping and livestock on plateau soils, while the outskirts of Laval face competition from urban growth and offer few sites that could genuinely be extended.
Sitting between Brittany and the Maine, the department gives easy access to feed mills, to the service businesses of the livestock sector and to buyers of finished pigs. For an incoming farmer, that position offsets a land market less strained than on the Breton side: for comparable building quality, entering the trade usually calls for more modest capital, which explains the steady interest shown by candidates from neighbouring departments.
Begin with the classified installation regime, which depends on the numbers kept: declaration, registration or authorisation, each with its own requirements and its own formality when the operator changes. Gather the prefectural order, any formal notices and the inspection reports. As Mayenne is designated a nitrate vulnerable zone, effluent management shapes the whole project: storage capacity, spreading windows, nitrogen ceilings and the area genuinely available around the livestock buildings must be set against the documents the seller hands over. The spreading agreements signed with neighbours repay close reading, not least the term they still have to run.
Then look at the biosecurity plan, the separation of traffic routes and the compliance of the accesses, and after that the contractual position: membership of a producer group, an integration contract, commitments under a quality scheme. Those ties do not follow the property automatically and are renegotiated with the organisation. The purchase remains subject to the structures control, the French authorisation regime for taking over farmland, and to SAFER's pre-emption right; in a GAEC or another farming company, entry may take the form of buying shares, with the accounting checks that implies.
The holdings shown on this page are entrusted by farmers preparing their succession, by firms specialising in rural land and by notarial practices based in Mayenne. Refine by type of unit, capacity or attached acreage, and set up an alert to receive new entries as they are published.
