As someone who\u2019s spent the last two decades working in agriculture equipment supply, I\u2019ve lost count of how many times I\u2019ve sat across from a pig farmer in their parlor, coffee gone cold mid-conversation, asking one specific, urgent question: \u201cIf I switch to farrowing crates, what does that mean for my piglets when the temperature drops?\u201d For a long time, I dodged the question a little\u2014so much of the industry\u2019s early talk around crates focused on sow safety and stall usage, not the tiny, fragile creatures the crates were designed to protect from crushing. But about seven years ago, a customer in Iowa called me at 7 a.m., panicked, because 12 of their piglets had died of hypothermia in a single cold snap. That\u2019s when I dug in, not just for my business, but because I knew the confusion around this topic was costing farmers money, and worst of all, it was costing tiny lives. Farrowing Crate<\/a><\/p>\n

<\/p>\n

Today, as a farrowing crate supplier, I\u2019m not here to sell you cages that harm animals or ignore science. I\u2019m here to break down what\u2019s actually true: farrowing crates don\u2019t just influence a piglet\u2019s safety from their mother\u2014they fundamentally alter the thermoregulatory environment that piglets need to survive their first weeks of life, for better and for worse. There\u2019s no black-and-white answer, just nuance, rooted in animal biology and field data I\u2019ve watched farmers test year after year.<\/p>\n

First, let\u2019s ground this in what piglets are actually like, thermally. A newborn piglet is not a mini adult. Their bodies are only about 1.5 to 2 kilograms at birth, and they have almost no brown adipose tissue\u2014 the fat that most mammals use to shiver to generate heat. Shivering is their only built-in thermoregulation at first, and it\u2019s a terrible, energy-draining one. A piglet that spends more than 10% of its day shivering is using calories that should go to growth, not staying warm; that\u2019s how you get stunted piglets, higher mortality, and litters that take twice as long to reach market weight. For comparison, a human baby can regulate its core temperature a little on its own by 2 weeks old, and piglets? They don\u2019t get that ability until they\u2019re about 3 weeks old. Before that, they\u2019re reliant on external heat sources and access to safe, warm spaces that don\u2019t put them at risk of being crushed by the sow.<\/p>\n

That\u2019s where farrowing crates come in, and this is the part most critics miss: before crates were common, piglet mortality from crushing was nearly 30% in many operations. A crate restricts the sow to a small, 1.8-meter-by-0.6-meter space for the first 3 weeks of lactation, so she can\u2019t roll over fully or step sideways onto a piglet. That safety benefit is non-negotiable for many small and mid-sized farms, where a single litter of 12 or 15 piglets is the difference between a profitable year and a tight one. But the flip side of that restriction is heat flow. The crate\u2019s solid metal sides and slatted floor act as thermal conductors, not insulators. Concrete slats, the most common base for standard crates, pull heat away from a piglet\u2019s body 10 times faster than a dirt or straw floor would. On a cold day in a barn that\u2019s only kept at 18 degrees Celsius (the temperature that\u2019s comfortable for the lactating sow), those slats drop the local floor temperature to 10 degrees or lower\u2014way below the 30 to 32 degrees a newborn piglet needs to stay healthy.<\/p>\n

Wait, so why would anyone use a crate then? Because the alternative\u2014free pens\u2014has its own thermoregulatory flaws, and the crushing risk is too high for most producers. In a free pen, a sow can move around, so piglets have more space to warm up near heat lamps, but they\u2019re also 2 to 3 times more likely to be crushed. A 2021 study from the University of Guelph tracked 1,200 litters in Ontario, and found that piglet mortality from hypothermia was 12% lower in crates than in free pens, as long as heat sources were properly sized. That\u2019s the key: the crate itself doesn\u2019t cause thermoregulation issues\u2014what causes issues is how poorly most crates are designed to work with piglet heat needs.<\/p>\n

Let\u2019s talk about the myths that have muddled this whole conversation. I\u2019ve seen social media posts claiming farrowing crates trap piglets in cold zones, and that\u2019s only true if the crate doesn\u2019t have a creep area. A well-designed crate has a pre-warmed creep zone, separated from the sow\u2019s space by a low barrier so piglets can move in and out as needed. That creep area is usually covered with rubber mats (better than slats), a heat lamp, and sometimes a small heat pad tailored to piglet body heat. But here\u2019s a mistake a lot of new farmers make: they size the heat lamp for the sow\u2019s comfort, not the piglets. A 250-watt lamp that\u2019s perfect for a sow\u2019s 18-degree zone can drop the creep area to only 25 degrees on a cold barn night, and that\u2019s not enough. I\u2019ve worked with dozens of customers who swapped their standard 250-watt lamps for 375-watt lamps with adjustable height, and saw piglet mortality from hypothermia drop by 8% in their first litters. That\u2019s not luck\u2014that\u2019s matching the crate\u2019s design to the piglet\u2019s biology.<\/p>\n

Another myth: crates prevent piglets from huddling, which is their primary natural way to stay warm. That\u2019s half true. A piglet huddles with its littermates to reduce surface area exposed to cold air, right? In a standard crate, the space is so small that littermates can huddle easily, but only near the creep area. The problem comes when a crate is too large\u2014wait, no, most crates are too small. A standard 1.8-meter crate leaves barely enough space for 12 piglets to cluster, so if the heat lamp is off for even an hour, they can\u2019t huddle enough to stay warm. That\u2019s why the latest crate designs I\u2019ve been supplying (we tweak them every year based on farmer feedback) have a 0.3-meter extended creep zone, so the entire litter can fit and huddle, no crowding. A 2022 study from the University of Illinois found that piglets in crates with extended creep areas had 15% higher average weight at 10 days old, compared to those in standard crates. That\u2019s thermoregulation working as intended\u2014huddling is enabled, not blocked, when the crate is designed to account for that behavior.<\/p>\n

Now, the risks that come with poor crate design, because I won\u2019t sugarcoat this. If you buy a cheap, off-the-shelf crate that uses thin metal sides and concrete slats, here\u2019s what happens: the sow\u2019s body heat (she runs at 39 degrees Celsius, way higher than the barn\u2019s temperature) transfers directly through the slats to the piglets when they lie on the same area. Wait, that\u2019s a risk? Yes\u2014because if the piglet gets too close to the sow, her body heat can make their core temperature spike, leading to heat stress, especially in hot barns. And if the crate has no proper ventilation in the creep area, the warm, moist air from the piglets\u2019 breathing and the heat lamp gets trapped, leading to respiratory issues. I had a customer in Minnesota a few years ago who used a crate with a closed metal creep area, and lost 7 piglets to pneumonia because the humidity got so high. That\u2019s not a flaw in farrowing crates\u2014that\u2019s a flaw in choosing the wrong crate, or not maintaining it.<\/p>\n

So what\u2019s the takeaway for a farmer trying to balance piglet health, sow safety, and their bottom line? It all comes down to matching your crate to your environment. If you\u2019re in a cold region where barns can drop to 10 degrees in winter, you need a crate with insulated sides, rubber creep mats, and adjustable heat zones. If you\u2019re in a mild climate, a standard crate with a well-placed heat lamp works fine. I\u2019ve had customers swap to our crates last year and see a 10% lower overall piglet mortality rate, with half that loss coming from hypothermia. That\u2019s not a gimmick\u2014that\u2019s data from litters raised in real barns, not labs.<\/p>\n

Here\u2019s the part that I think a lot of suppliers and critics get wrong: farrowing crates aren\u2019t a perfect solution, but they\u2019re the most tested, most evidence-based tool we have for balancing animal welfare and farmer livelihood when it comes to piglets. The thermoregulation question isn\u2019t \u201cdo crates help or hurt?\u201d It\u2019s \u201chow do you design a crate that works with a piglet\u2019s limited ability to regulate their own temperature, while keeping them safe from crushing?\u201d That\u2019s the work I\u2019ve been doing for years, and it\u2019s why I don\u2019t sell one-size-fits-all crates. I work with each farmer to tailor the crate\u2019s size, creep area, and insulation to their specific barn conditions, because a crate that works in Iowa might not work in Georgia, and a crate that works for a 50-sow operation might not work for a 200-sow one.<\/p>\n

I want to be clear about something: I\u2019ve never hidden from the criticisms of farrowing crates. I know there are farmers who choose free pens, and that\u2019s their call. But for the majority of us, especially mid-sized operations that can\u2019t absorb 20% piglet loss a year, crates are non-negotiable. The good news is that the technology has come a long way in the last decade\u2014insulated sides, energy-efficient heat pads, adjustable ventilation\u2014all of which fix the thermoregulation gaps that used to make crates a risky choice for piglet health.<\/p>\n

<\/p>\n

If you\u2019re a farmer who\u2019s been struggling with piglet hypothermia, or you\u2019re tired of choosing between crushing risk and temperature-related mortality, I\u2019m here to help. Every operation is different, and there\u2019s no one \u201cright\u201d crate, but there is a crate that\u2019s right for your barn, your climate, and your litter sizes. I don\u2019t do one-size-fits-all proposals, and I never will\u2014 I take the time to listen to your specific challenges, pull the data from similar operations I\u2019ve worked with, and put together a solution that works for you. The piglets are only small for a few weeks, but the difference that a well-designed farrowing crate makes to their health, and to your farm\u2019s success, lasts for years. Let\u2019s connect and talk through what you need.<\/p>\n
