Choosing the right pig feeder can affect how often feed needs to be added, how much feed is available at one time, and how easy the feeding area is to manage. Automatic and on-demand feeders are designed to make feeding more convenient by storing feed and controlling how it reaches the trough.

If you're comparing options for your pigs, Pig Feeders at Barn World includes nursery, wean-to-finish, and finishing feeders in several capacities. The current selection includes gravity-fed and mechanical on-demand designs for different stages of pig growth.

What Is an Automatic Pig Feeder?

The term automatic pig feeder can describe several different types of feeding equipment. Some systems use electronic controls, timers, or sensors to dispense feed. Others use mechanical designs that allow pigs to activate the feeder as they eat.

For many livestock operations, a mechanical on-demand feeder provides the automation needed without requiring an electronic control system. Feed is stored in a hopper, and the feeder controls how it moves into the trough.

Barn World's pig feeders include designs that range from traditional gravity feeding to on-demand mechanical feeding. Understanding the difference is important when comparing feeders.

How Automatic and On-Demand Pig Feeders Work

A gravity feeder allows feed to move from the hopper into the trough as space becomes available. This gives pigs access to feed without requiring a person to fill the trough each time they eat.

An on-demand feeder takes the concept a step further by controlling the release of feed through a mechanical system. As pigs interact with the feeder, the mechanism allows additional feed to enter the trough.

The goal is to keep an appropriate amount of feed available without simply allowing the trough to fill continuously.

Some pig feeders are also designed to change how they operate as pigs grow. For example, a feeder may provide more conventional gravity access for young pigs and transition toward on-demand feeding as the pigs become strong enough to operate the mechanism.

Pros of Automatic Pig Feeders

Automatic and on-demand pig feeders can provide several practical advantages, particularly when feeding groups of pigs.

Less Frequent Manual Feeding

A feeder with a hopper can hold a substantial amount of feed, reducing the need to repeatedly carry feed to the trough throughout the day.

This does not eliminate the need to monitor the pigs or the feeder, but it can make the daily feeding routine more convenient.

Feed Is Available From a Hopper

Instead of putting the entire day's feed directly into an open trough, a hopper stores the feed above the feeding area and releases it as needed.

This can make feeding easier to manage, particularly when several pigs are sharing a feeder.

Controlled Feed Delivery

Mechanical on-demand feeders can control the amount of feed that moves into the trough. Rather than continuously dropping feed, the mechanism responds to the pigs' interaction with the feeder.

How effectively this controls feed depends on the feeder design, adjustment, the pigs using it, and how the equipment is managed.

Multiple Pigs Can Feed From One Unit

Many pig feeders use a circular or multi-station trough design that allows several pigs to feed at the same time.

This can be especially useful when selecting a feeder for a group rather than a single animal. The number of feeding positions, feeder diameter, and recommended number of pigs should all be considered.

Cons and Considerations With Automatic Pig Feeders

Automatic feeders are not maintenance-free, and the right feeder depends on the operation. There are several things to consider before making a purchase.

Initial Equipment Cost

A larger feeder can cost more than a simple open trough. The investment also increases when the feeder has additional mechanical components or greater capacity.

Compare the feeder's capacity, construction, feeding design, and intended number of animals rather than looking only at the initial purchase price.

Mechanical Components Need Attention

Mechanical on-demand feeders have moving parts that should be inspected periodically. Feed buildup, damage, wear, or improper adjustment can affect how the feeder operates.

Routine inspection is particularly important when the feeder is being used every day by a large group of pigs.

Feeders Still Need to Be Checked

An automatic feeder does not mean the feeding system can simply be ignored. The hopper needs to be checked, feed levels need to be monitored, and the trough should be inspected regularly.

Checking the feeder also allows the producer to observe the pigs and make sure all animals are getting appropriate access to feed.

Young Pigs May Use a Feeder Differently

Young pigs may not have the same ability to operate a mechanical on-demand system as larger pigs. This is one reason feeder design matters when selecting equipment for nursery pigs.

Some feeders are specifically designed around younger pigs and their feeding behavior, while others are intended for larger grower or finishing pigs.

Automatic Feeders and Feed Waste

Feed waste is one of the reasons producers consider controlled-feed and on-demand feeder designs.

Feed placed in an open trough can be spilled, pushed onto the ground, or contaminated as pigs eat. A feeder that controls how feed enters the trough can help reduce the amount of feed sitting in the feeding area.

However, there is no single waste percentage that applies to every feeder or operation. Feed waste depends on the feeder, feed type, adjustment, pig behavior, stocking density, and management.

The best way to evaluate a feeder is to look at how its design controls feed flow and whether that design fits the pigs using it.

Nursery Pig Feeders

Nursery pigs have different feeding requirements and physical capabilities than larger finishing pigs, so feeder size is an important consideration.

A nursery feeder should provide appropriate access for smaller pigs while offering enough capacity for the group being fed.

Barn World's current pig feeder selection includes nursery feeders in 50-, 160-, and 235-pound capacities. The collection's published specifications also identify different pig-size ranges and recommended group sizes for these models.

When comparing nursery feeders, look at the trough dimensions, feeder height, capacity, number of feeding positions, and the size of the pigs expected to use the feeder.

Wean-to-Finish Pig Feeders

Wean-to-finish feeders are designed for pigs that remain in the same general feeding system as they grow from weaning toward market weight.

This type of feeder needs enough capacity for a growing group while providing appropriate access throughout the feeding period.

Barn World's current selection includes wean-to-finish feeders with capacities of 235, 390, and 785 pounds. The published specifications list these models for groups of up to 60 pigs, with differences in feeder height and trough dimensions.

Choosing between these capacities depends on the number of pigs, available feeding space, refill schedule, and how the feeder will be managed.

Finishing Pig Feeders

Finishing pigs are larger and consume more feed than nursery pigs, so feeder capacity and feeding access become especially important.

A finishing feeder should provide enough trough space for the intended group while holding enough feed to fit the producer's normal feeding routine.

Barn World's current collection includes finishing feeders in 235-, 390-, and 785-pound capacities. Comparing these sizes can help producers match feeder capacity to the number and size of pigs being fed.

Gravity Feeders vs. On-Demand Feeders

One of the most important distinctions when comparing pig feeders is how feed moves from the hopper into the trough.

Feature	Gravity Feeding	On-Demand Feeding
Feed flow	Feed moves into the trough as space becomes available	Mechanical action controls additional feed entering the trough
Moving parts	Generally fewer	Uses a mechanical feed-control system
Management	Simple feed delivery	Designed to provide more controlled feed delivery
Best consideration	Simple feeding access and capacity	Controlled feed flow and mechanical operation

Neither design is automatically right for every operation. The better choice depends on the pigs, feeder location, desired feeding method, and how the producer wants to manage feed.

Feeder Capacity and Number of Pigs

Capacity is only one part of choosing the right feeder. The number of pigs using the feeder and the amount of available trough space are equally important.

A feeder that holds a large amount of feed may still be a poor fit if there are not enough feeding positions for the group. Conversely, a smaller feeder may work well for a nursery group that requires less feed capacity.

Consider both hopper capacity and feeding access when comparing models.

Keeping the Feeding Area Clean

The design of the feeder can influence how easy the feeding area is to manage, but good feeder design does not eliminate the need for regular cleaning.

Inspect the trough for accumulated feed, moisture, dirt, and other material. Check around the feeder for spilled feed and make adjustments if pigs are consistently pushing excessive feed onto the ground.

Poly feeder components can also be useful in livestock environments because they do not rust like conventional steel components. The specific construction varies by model, so review the product specifications before choosing a feeder.

Maintenance for Automatic Pig Feeders

Routine maintenance is part of owning any mechanical livestock feeder.

• Check the hopper and trough regularly.
• Inspect moving components for wear or damage.
• Make sure feed can move through the feeder properly.
• Remove accumulated feed and debris as needed.
• Check the feeder's position and stability.
• Follow the manufacturer's instructions for adjustments and maintenance.

Regular checks can help identify a feeding problem before it becomes a larger equipment issue.

Is an Automatic Pig Feeder Right for Your Operation?

An automatic or on-demand feeder may make sense if you want to store more feed at the feeding location, reduce the amount of manual trough filling, or have more control over how feed enters the trough.

A simpler gravity feeder may be appropriate when straightforward feed delivery is the priority. An on-demand mechanical design may make more sense when controlling feed flow is an important consideration.

The size and age of the pigs should also influence the decision. A feeder designed for nursery pigs is not necessarily the right choice for a group of finishing hogs.

What to Consider Before Buying a Pig Feeder

Before choosing an automatic or on-demand pig feeder, consider:

• Pig size: Choose a feeder designed for the pigs that will use it.
• Number of pigs: Match feeding positions and capacity to the size of the group.
• Feeder capacity: Consider how much feed you want the hopper to hold between refills.
• Feed delivery: Decide whether gravity or controlled on-demand feeding better fits your operation.
• Trough design: Consider how many pigs can feed comfortably at one time.
• Construction: Look for materials appropriate for daily livestock use.
• Maintenance: Consider access to moving parts and how easy the feeder is to clean and inspect.
• Location: Make sure there is enough room for the feeder and the pigs using it.

Frequently Asked Questions About Automatic Pig Feeders

What is an automatic pig feeder?

An automatic pig feeder stores feed and delivers it to pigs without requiring the producer to manually fill the trough every time the pigs eat. Some feeders use gravity, while others use mechanical on-demand systems.

Are automatic pig feeders electronic?

Not necessarily. Automatic pig feeders can use simple gravity or mechanical systems rather than electronics, timers, or sensors. The feeder's specific design determines how feed is delivered.

What is an on-demand pig feeder?

An on-demand pig feeder uses a mechanical system that allows pigs to activate or control the release of additional feed into the trough.

Are automatic feeders good for nursery pigs?

Automatic and mechanical feeders can be used for nursery pigs, but the feeder should be designed for the size and feeding behavior of young pigs. Capacity, feeder height, trough dimensions, and feeding positions should all be considered.

How many pigs can use one feeder?

The number depends on the feeder design, number of feeding positions, pig size, and manufacturer's recommendations. Barn World's current pig feeder specifications list different capacities and recommended group sizes for nursery and wean-to-finish models.

Do automatic pig feeders reduce feed waste?

A controlled-feed or on-demand design can help manage how much feed enters the trough, but actual feed waste varies by feeder, adjustment, feed type, pig behavior, and management.

Do automatic pig feeders require maintenance?

Yes. Feeders should be inspected regularly for feed buildup, wear, damage, blockages, and proper operation. Mechanical on-demand feeders require particular attention to their moving components.

What size pig feeder should I buy?

Consider the pigs' current size and expected growth, the number of animals using the feeder, hopper capacity, trough space, and how frequently you want to refill the feeder.
