In factory farming the owners strap the sows to a frame. That way she can’t move much and won’t crush her piglets.
FYI, this from the DEFRA website with the Govt strategy on this, and some facts and figures and references. Note para 2 sentence 1 of the excerpt: apparently the piglet loss rate for the unconfined sows is about the same as that for sows stuck in farrowing crates (though that is not stated here).
"For pigs, a significant number of sows are confined in farrowing crates from around 5 days before they are due to give birth, until the piglets are weaned at approximately 28 days of age. A farrowing crate, which is designed to protect piglets from being crushed by the sow, restricts the sow’s movement, preventing her from turning around and performing natural behaviours, such as nest building. Approximately 92% of indoor production systems still use farrowing crates [18].
There is already a significant outdoor pig sector with 50% [19] of the national sow breeding herd giving birth freely on outdoor units with no option for confinement. Currently around 8% [20] of indoor production has already moved to alternative farrowing systems to improve sow welfare, protect piglet welfare and ensure human safety. We want to work with the sector to move all sows out of farrowing crates over a sustainable transition period. Removing the use of intensive confinement systems is an essential component of the government’s plan to ensure all farmed animals have a life worth living, and that as many animals as possible have a good life. Ending the use of cages and crates is therefore a key priority for this government.
