Expected Feed Quantity at Each Pig Growth Stage (Simple, Practical Guide for Farmers) By GreatLadyFarmer | GricGreat Limited
Feeding pigs is not about guessing. It is one of the biggest factors that determines whether you make profit or loss.
Many pig farmers struggle not because feed is expensive… But because they don’t know how much to give at each stage.
Some underfeed → pigs grow slowly Some overfeed → waste money and reduce efficiency
The truth is simple: Each stage of a pig’s life requires a different feed quantity and strategy.
Let’s break it down in a very practical and easy way.
1. Piglets (Birth to 4 Weeks – Suckling Stage)
At this stage, piglets depend mainly on their mother’s milk.
What you should know:
They are not eating full feed yet
Their digestive system is still developing
The sow’s milk is their main nutrition
Feed Quantity:
No major feed required initially
Introduce creep feed from day 7–10
Quantity: 👉 10g – 50g per piglet per day (very small amounts)
Key Focus:
Fresh, clean creep feed daily
Do not leave stale feed
Encourage early eating habits
Common Mistake:
Many farmers ignore creep feeding. Later, piglets struggle during weaning.
2. Weaner Stage (4–8 Weeks)
This is a very sensitive stage.
Piglets are separated from the sow. Stress is high. Appetite may drop.
Feed Quantity:
0.25kg – 0.5kg per pig per day
Feeding Style:
Small meals, multiple times daily
Always fresh and clean
What Happens If You Get It Wrong:
Poor growth
Diarrhea
High mortality
Key Tip:
Do not suddenly change feed. Transition gradually from creep feed.
3. Grower Stage (8–16 Weeks)
Now pigs are stronger and growing fast.
This stage determines how quickly your pigs reach market weight.
Feed Quantity:
1kg – 2kg per pig per day
Growth Expectation:
Rapid weight gain
Strong bone development
Important:
Feed must be balanced with:
Protein
Energy
Minerals
Common Mistake:
Farmers reduce feed to “save cost” → This slows growth and increases total feeding time
4. Finisher Stage (16 Weeks to Market Weight)
This is the stage where pigs gain most of their weight.
Feed Quantity:
2kg – 3.5kg per pig per day
Goal:
Fast weight gain
Good body condition
Key Focus:
Energy-rich feed
Consistency in feeding
Mistake to Avoid:
Irregular feeding times → Causes stress and poor feed conversion
5. Pregnant Sows (Gestation Stage)
Pregnant pigs need controlled feeding.
Too much feed = fat pigs Too little feed = weak piglets
Feed Quantity:
2kg – 2.5kg per day
Feeding Strategy:
Increase gradually in late pregnancy
Why It Matters:
Supports fetal development
Prevents birthing complications
6. Lactating Sows (After Farrowing)
This is the stage where feed demand is highest.
The sow is feeding multiple piglets.
Feed Quantity:
4kg – 6kg per day (or more depending on litter size)
Rule:
The more piglets → the more feed needed
Important:
Plenty of clean water
High-quality feed
If You Underfeed:
Sow loses weight
Milk production drops
Piglets suffer
7. Boars (Male Breeding Pigs)
Boars don’t need too much feed.
Overfeeding reduces performance.
Feed Quantity:
2kg – 3kg per day
Goal:
Maintain strength
Avoid excess fat
Simple Feed Summary Table
Piglets: 10g – 50g
Weaners: 0.25kg – 0.5kg
Growers: 1kg – 2kg
Finishers: 2kg – 3.5kg
Pregnant sows: 2kg – 2.5kg
Lactating sows: 4kg – 6kg
Boars: 2kg – 3kg
Important Factors That Affect Feed Quantity
Feed quantity is not fixed for every farm.
These things can change how much pigs eat:
1. Breed
Some breeds grow faster and eat more.
2. Weather
Hot weather → pigs eat less
Cold weather → pigs eat more
3. Health Status
Sick pigs eat less.
4. Feed Quality
Low-quality feed → pigs eat more but grow less
5. Housing
Poor environment reduces appetite
Signs You Are Feeding Correctly
Pigs are active
Steady weight gain
Minimal feed waste
Calm pen environment
Signs You Are Underfeeding
Slow growth
Weak pigs
Fighting for food
Thin body
Signs You Are Overfeeding
Excess fat
Wasted feed on the ground
Dirty pens
Increased feeding cost
Practical Feeding Tips Every Farmer Should Follow
1. Feed at the Same Time Daily
Consistency improves growth.
2. Use Proper Feeders
Reduces waste.
3. Always Provide Clean Water
Water affects feed intake.
4. Observe Your Pigs Daily
Your pigs will tell you if something is wrong.
5. Avoid Sudden Feed Changes
Always transition gradually.
The Truth Many Farmers Ignore
Pigs don’t fail because of feed cost alone.
They fail because:
Feed is not measured
Feeding is not consistent
Growth stages are ignored
A farmer who understands feeding stages will always have an advantage.
Final Thought
Feeding pigs is not about giving “plenty feed.”
It is about giving the right quantity at the right stage.
That is where profit comes from.
If you master feeding, you control:
Growth rate
Health
Profit
