Managing a wet/dry feeder isn’t complicated — but it does play by different rules than a dry feeder or single-space unit. Get these fundamentals right and you’ll see it show up where it counts: average daily gain (ADG), feed conversion ratio (FCR), and your feed budget. Here are nine tips to get the most out of your wet/dry feeder.
Here's how to get the best results from your wet/dry feeder:
1. Rethink Pen Density Wet/dry feeders let pigs eat up to 20% faster than they do on a dry feeder, since less time is spent manipulating feed and more time actually consuming it. That means you can safely run more pigs per linear inch (cm) of feeder space than conventional space-allowance charts assume. Before you finalize stocking density, confirm your feeder-space budget accounts for the wet/dry advantage — running dry-feeder math on a wet/dry system leaves space (and profit) on the table.
2. It’s All About Water Flow Controlling water flow at the nipple is the single most important variable in wet/dry feeder management. Nipples that can’t hold flow at the correct rate for the pig’s size and stage create a cascade of problems — flooded pans, stale or moldy feed, and a measurable hit to ADG and FCR. Adaptive-flow nipple technology exists specifically to solve this, holding consistent output across a pig’s growth curve instead of requiring constant manual tinkering.
3. Your Wet/Dry Feeder Should Be the Primary Water Source The nipples inside the feeder need to be doing the heavy lifting for hydration — not the supplemental waterer in the corner of the pen. Every time a pig drinks at the feeder, it eats. Design your water strategy around that behavior and feed intake follows.
4. Plan Your Supplemental Water Sources Carefully Once your feeder nipples are reliably controlling flow, think through how many supplemental water sources the pen actually needs. Over-supplying water elsewhere in the pen can pull pigs away from the feeder and undercut the “drink-to-eat” behavior you’re trying to reinforce.
5. Adjust Feed Flow Based on Feed Type Mash and pellets move through a feeder differently, and even pellet quality and granularity can shift flow rates. A feeder with tool-free, repeatable flow adjustment (Crystal Spring’s EZ-Adjust™ mechanism, for example, moves in 1/16″ / 1.5mm increments) lets you dial in the right setting for whatever ration is in the bin — without guesswork.
6. Ensure Proper Ventilation Ventilation isn’t just a comfort issue — it’s a feeding-behavior issue. Poor air quality and inconsistent airflow are linked to tail biting, increased aggression, and irregular feeding patterns that drag down intake. Work with your ventilation provider to confirm you’re hitting the right minimum, transitional, and tunnel ventilation rates for each stage of production, not just a barn-wide average.
7. Manage Barn Temperature — Especially for Piglets Keeping nursery pigs within their thermoneutral zone (TNZ) is critical to normal eating behavior. If you notice piglets piling in corners or bedding down inside the feeder trough itself, don’t assume it’s a behavior issue first — check the thermostat. Cold pigs eat less, plain and simple.
8. Place Supplemental Water on the Opposite Side of the Pen Positioning supplemental water as far from the feeder as the pen allows keeps the dunging area away from the feed line and reinforces the feeder nipple as the pig’s go-to water source. Pigs will still use supplemental water for an extra drink or to cool off on hot days — but the feeder stays the primary hydration point, which is exactly where you want feed intake behavior anchored.
9. Reducing Feed Waste Is a Direct Line to Profit Feed remains the single largest input cost in pork production — commonly landing in the 50–60% range of total cost of production, depending on the grain market cycle. In a 1,200-head barn, that can mean tens of tons of feed moving through each feeder every year. A feeder engineered for minimal waste and consistent flow control isn’t a minor efficiency play — it’s one of the highest-leverage decisions you’ll make on the barn floor.
