Some piglets walk away from the sow and start eating well. Others stand around the feeder, nibble very little and begin losing condition.
When that happens, do not keep changing feeds every few hours. Start with the basics: water, feeder access, feed freshness, pen comfort and whether the piglets were already familiar with solid feed before weaning.
A newly weaned piglet that does not eat is not just a feeding problem. It can quickly become a health problem.
Why do piglets eat less after weaning?
Weaning changes several things at once.
The piglet loses access to the sow and milk. It may move to a new pen, meet unfamiliar piglets, face a different feeder and start depending completely on solid feed and water.
That stress can reduce feed intake for a short period.
The farmer’s job is to make the change as smooth as possible and to notice early when low intake is becoming dangerous.
1. Check water first
A piglet that is not drinking well will usually not eat well.
Walk through the pen and check:
- whether every drinker is working;
- whether the water flow is strong enough;
- whether the drinker is at the right height;
- whether smaller piglets can reach it;
- whether water is clean; and
- whether the pen becomes wet because of leaking drinkers.
Do not assume water is available just because there is a drinker in the pen.
2. Keep the first feed familiar
If piglets were eating creep feed before weaning, continue with a familiar starter feed for the first part of the transition.
Do not change from sow, pen, water system and feed all at once if you can avoid it.
A familiar feed can make it easier for piglets to start eating after separation.
3. Use fresh starter feed
Newly weaned piglets need a starter feed that is palatable, easy to eat and suited to their age.
Feed should be:
- fresh;
- dry;
- free from mould;
- free from a rancid smell;
- protected from contamination; and
- offered in a feeder that piglets can use easily.
Do not leave stale feed sitting in the feeder because you want to avoid waste.
4. Use small frequent offers when intake is poor
If piglets are slow to approach the feeder, offer small amounts of fresh feed more often rather than filling the feeder with a large amount that may become stale.
The aim is to keep feed available and attractive without creating waste.
Watch whether piglets are actually eating. Do not judge by how much feed you put into the pen.
5. Mat feeding can help some piglets find feed
Mat feeding means placing a small amount of starter feed on a clean flat surface close to the normal feeder.
This can encourage curious piglets to investigate the feed and may help the group start eating.
Keep the surface clean and dry. Remove old feed before adding fresh feed.
Mat feeding should support normal feeder use, not replace it.
6. Avoid overcrowding around feeders
Piglets can have feed in the pen and still fail to eat enough if stronger animals control access.
Check whether:
- too many piglets crowd one feeder;
- small piglets are pushed away;
- feeders are placed in poor locations; and
- there is enough usable feeder space.
Sometimes the quietest piglet in the pen is the one eating the least.
7. Keep the pen comfortable
Newly weaned piglets do not handle environmental stress well.
Check:
- pen temperature;
- cold draughts;
- wet floors;
- poor ventilation;
- overcrowding;
- rough mixing; and
- excessive noise or disturbance.
Piglets that are too cold may huddle. Piglets that are too hot may spread out and reduce feed intake.
8. Keep groups stable where possible
Mixing unfamiliar piglets can cause fighting and social stress.
Where possible, avoid repeated regrouping during the first days after weaning.
Give the group enough space so weaker piglets can move away from more dominant animals.
9. Do not improvise the ration with random foods
One common mistake is offering grains, fruit, vegetables, kitchen waste and protein ingredients in an attempt to make piglets eat something.
That can create a badly balanced diet and may make digestive problems worse.
Use a properly formulated starter feed rather than creating a mixture by guesswork.
What about gruel feeding?
Gruel feeding means mixing a suitable starter feed with water to make a soft feed.
It can help some piglets during the transition, especially where dry feed intake is poor.
But it needs strict hygiene.
Wet feed spoils quickly. Mix only what the piglets can consume promptly, clean the container properly and do not leave old gruel in the pen.
Do not use random cereal and water mixtures and call them a complete starter ration.
What about milk replacer?
Milk replacer can be useful in some management systems, but it is not automatically needed for every weaned piglet.
If it is used, it should fit the farm’s feeding programme and be prepared according to the product instructions.
Do not use it to cover up a poor starter feed, dirty pen or water problem.
How do I know whether the piglets are eating enough?
Do not rely on one piglet nibbling at the feeder.
Check:
- how much feed disappears;
- whether all piglets visit the feeder;
- body condition;
- daily activity;
- water use;
- manure consistency;
- weight gain where practical; and
- whether some piglets are falling behind.
One or two slow piglets can be hidden inside an apparently normal group.
When should low feed intake worry you?
Get concerned when poor eating comes together with:
- diarrhoea;
- weakness;
- sunken sides;
- dehydration;
- vomiting;
- coughing;
- difficulty breathing;
- fever;
- persistent huddling;
- rapid weight loss; or
- rising mortality.
At that point, it is no longer enough to keep trying different feeds.
What if diarrhoea starts after weaning?
Post weaning diarrhoea can have several causes, including infection, stress, feed change and poor hygiene.
Do not automatically put antibiotics into the water.
Check water, feed, pen hygiene, temperature and the number of affected piglets, then get veterinary help if the problem is persistent, severe or spreading.
Use our Piglet Diarrhoea guide for a more detailed check.
Should I isolate a piglet that is not eating?
If one piglet is much weaker than the group, is being bullied or shows signs of illness, separate observation may be useful.
But do not isolate healthy piglets unnecessarily because social stress can also affect feeding.
The reason for separation should be clear.
Should piglets be fed twice a day?
Do not use one fixed feeding frequency for every nursery system.
The correct approach depends on feeder design, feed type, age, farm routine and whether feed is offered freely or in measured meals.
The important thing is that fresh feed is available when piglets are ready to eat and that stale feed does not build up.
How long does it take for piglets to settle after weaning?
There is no single number for every farm.
Some piglets adapt quickly. Others take longer, especially if they were weaned small, moved a long distance, mixed aggressively or were not used to solid feed before weaning.
Watch the group instead of waiting for a fixed number of days.
Does poor feed intake always mean the feed is bad?
No.
Feed can be good and piglets may still eat poorly because of:
- water failure;
- temperature stress;
- fighting;
- poor feeder access;
- disease;
- transport stress; or
- sudden management changes.
Check the whole system before changing the feed.
Simple first day check after weaning
- Check every drinker.
- Check pen temperature.
- Offer fresh starter feed.
- Watch whether all piglets approach the feeder.
- Look for fighting or bullying.
- Check for diarrhoea.
- Look for weak or dehydrated piglets.
- Remove stale or wet feed.
- Record any mortality.
Simple first week check
During the first week, track:
- feed used;
- water problems;
- diarrhoea cases;
- mortality;
- weak piglets;
- pen temperature problems;
- feed changes; and
- weight or body condition where possible.
The goal is not just to get piglets eating. The goal is to get them eating enough to keep growing without creating digestive or health problems.
Common mistakes after weaning
- Changing feed repeatedly because intake looks low.
- Ignoring water supply.
- Overfilling feeders with feed that becomes stale.
- Offering random grains, fruit and vegetables as a starter diet.
- Leaving wet gruel in the pen for too long.
- Overcrowding piglets around one feeder.
- Ignoring diarrhoea because the piglets are still standing.
- Mixing unfamiliar piglets repeatedly.
- Using antibiotics without a clear diagnosis.
Bottom line
If newly weaned piglets are not eating, start with water, fresh starter feed, feeder access, pen comfort and stress.
Keep the first feed familiar where possible. Offer fresh feed in a way the piglets can find easily. Watch the smallest piglets closely and investigate diarrhoea or weakness early.
Do not chase appetite with random feeds. Fix the reason the piglets are not eating.
Veterinary note: Persistent feed refusal, diarrhoea, dehydration, breathing problems or rising mortality need proper animal health assessment.
