Can Spoilt Cassava Be Used as Chicken Feed in Nigeria? A Practical Guide from 8 Years of Experience
My name is Pius Emeka. I run a chicken farm in Oyi Local Government Area, Anambra State. I’ve been raising chickens for eight years now.
One question I hear often is this: “Can spoilt cassava be used as chicken feed?”
The short answer is no. Spoilt cassava should not be fed to chickens. It contains harmful toxins that can kill your birds.
Let me explain why. And I’ll share what happened to a farmer I know who tried it.
You don’t have to figure this out alone. Many resources exist to help you succeed.
Government Programs

- Cassava processing methods
- Disease prevention
- Record keeping and profitability
Many other experienced farmers offer similar training. Look for farmers with proven track records. Ask for references. Visit their farms before paying for training.
Online Resources
While I prefer hands-on learning, some websites offer good information:
- Nigerian Poultry Science Association publications
- Federal Ministry of Agriculture resources
- University agricultural extension websites
Always verify online information with local experts. What works in Europe or America may not work in Nigerian conditions.
The Economic Impact: Real Numbers from My Farm
Let me open my books and show you real numbers. This is data from my farm between January and December 2024.
Annual Feed Cost Analysis
Total birds raised: 2,400 broilers across 4 batchesย Feed consumption: 420 bags (50kg each)ย Average feed cost per bag: โฆ10,200 (using processed cassava)ย Total feed expense: โฆ4,284,000
If I used only commercial feed at โฆ15,000 per bag:ย Total cost: โฆ6,300,000
Annual savings: โฆ2,016,000
This saving goes straight to profit. It makes the difference between a thriving business and barely breaking even.
But here’s the critical point: These savings only work with safe, properly processed ingredients. Using spoilt cassava would have destroyed everything.
Return on Investment for Processing Equipment
Remember the โฆ25,500 I invested in cassava processing equipment? Let me show you the return.
Monthly savings from using processed cassava: โฆ168,000ย Time to recover equipment cost: Less than 1 weekย Equipment lifespan: 3-5 years with proper maintenance
The mathematics is simple. Good equipment pays for itself almost immediately.
Regional Variations: Cassava Availability Across Nigeria
Cassava availability and prices vary by region. This affects whether cassava makes sense for your feed program.
Southern Nigeria (My Region)
In Anambra, Abia, Imo, Enugu, and surrounding states, cassava is abundant. Fresh cassava costs โฆ150-โฆ200 per kilogram. Processing facilities exist in most local government areas.
This makes cassava an excellent feed ingredient here. The economics work well. Supply is reliable year-round.
Northern Nigeria
Cassava is less common in northern states. Maize and millet dominate. Cassava prices are higher due to transportation costs.
Farmers in Kano, Kaduna, or Sokoto might find cassava less economical. Focus on locally available ingredients instead.
Western Nigeria
Ogun, Oyo, Osun, and Ondo states have strong cassava production. Many garri processing facilities operate here.
Cassava makes excellent economic sense in these states. Competition among processors keeps prices reasonable.
Environmental Considerations and Waste Management
Proper cassava processing generates waste. Managing this waste correctly protects your farm and community.
Cassava Peel Disposal
Fresh peels can be:
- Dried and fed to other animals (goats, sheep) in small amounts
- Composted for use in crop farming
- Sold to other livestock farmers
Never dump fresh peels in water sources. The cyanide can contaminate water supplies. This has happened in some communities. Local authorities take this seriously.
Water Management During Processing
Washing cassava generates wastewater containing soil and cyanide compounds. Don’t let this water enter streams or wells.
On my farm, I use a soak pit system. The water drains into a designated pit away from water sources. The soil filters out contaminants naturally.
This costs about โฆ15,000 to construct. It’s worth it for environmental protection and community relations.
The Future of Cassava in Nigerian Poultry Farming
Cassava will become more important in Nigerian poultry farming. Let me tell you why.
Rising Maize Prices
Maize prices increased by 45% between 2022 and 2024. This trend will likely continue. Climate change, insecurity in farming areas, and increased demand all push prices higher.
Cassava offers an alternative. When processed correctly, it performs nearly as well as maize. The price remains more stable.
Government Support Programs
NALDA and other agencies are promoting cassava utilization in livestock farming. They provide training and sometimes subsidize processing equipment.
These programs will expand. Farmers who learn proper cassava processing now will benefit greatly.
Technology Improvements
New cassava varieties with lower cyanide content are being developed. The National Root Crops Research Institute releases improved varieties regularly.
Better processing equipment is also becoming available. Solar dryers and mechanical peelers make processing easier and safer.
But technology doesn’t change the basic rule: spoilt cassava is dangerous. No variety or processing method makes spoilt cassava safe.
Frequently Asked Questions About Cassava and Chicken Feed
Can I Use Cassava Peel Directly from Garri Processors?
Only if the peels are fresh and you dry them immediately. Most garri processors generate peels throughout the day. If collected daily and dried properly, these peels work well.
But peels that have sat for several days are dangerous. Check for signs of spoilage before buying. When in doubt, walk away.
I buy peels from three processors in Oyi. I collect twice dailyโmorning and evening. This ensures freshness. The processors know my schedule and keep the peels separated for me.
How Long Can Dried Cassava Be Stored Safely?
Properly dried cassava (below 12% moisture) stores for 6-8 months. Storage conditions matter greatly.
Use these guidelines:
- Store in cool, dry location
- Keep away from direct sunlight
- Use airtight containers or bags
- Check monthly for mold or insects
- Don’t store near water sources or damp areas
On my farm, I store in a dedicated room with good ventilation. I use thick polypropylene bags tied tightly. I’ve never had spoilage with this system.
What Percentage of Cassava Can Replace Maize in Feed?
This depends on bird age and purpose:
Broiler starter (0-4 weeks): Up to 15% of maize can be replacedย Broiler finisher (4-8 weeks): Up to 30% replacement possibleย Layer feed: Up to 40% replacement works wellย Breeder feed: Limit to 20% replacement
These percentages assume properly processed cassava flour with good quality control. Start with lower percentages. Increase gradually while monitoring bird performance.
Can Fermented Cassava Be Used for Chicken Feed?
Controlled fermentation can actually reduce cyanide levels. But this is different from spoilage.
Proper fermentation:
- Uses specific starter cultures
- Happens under controlled conditions
- Takes 3-5 days
- Results in consistent, safe product
- Requires technical knowledge
Spoilage:
- Happens naturally with harmful bacteria
- Uncontrolled process
- Increases toxins and mold
- Dangerous for chickens
- Should never be used
Don’t confuse the two. Unless you have proper training in cassava fermentation, stick with the sun-drying method I described earlier.
Is Bitter Cassava More Dangerous Than Sweet Cassava?
Yes. Bitter cassava varieties contain much higher cyanide levels than sweet varieties. In Nigeria, we grow both types.
Bitter cassava (like TMS varieties used for garri):
- Contains 200-400 mg cyanide per kg
- Requires extensive processing
- Takes longer to become safe
- Needs extra care in handling
Sweet cassava:
- Contains 15-50 mg cyanide per kg
- Easier to process safely
- Faster drying time
- Generally safer for feed use
I prefer sweet cassava varieties for my chicken feed. They’re safer and easier to process. But even sweet cassava must be properly dried before use.
What Should I Do with Cassava That Started Spoiling During Drying?
Throw it away. Don’t feed it to any animal. Don’t try to save it.
I know it hurts to waste cassava you paid for. But the cost of sick or dead birds is much higher.
Last year, Brother Uchenna tried to salvage partially spoilt cassava. He thought sun-drying would kill the toxins. It doesn’t work that way. He lost 45 birds worth โฆ90,000.
Prevention is better than cure. Monitor your drying cassava daily. If spoilage begins, remove affected pieces immediately. Don’t let them contaminate the good cassava.
Can I Mix Spoilt Cassava with Other Ingredients to Dilute the Toxins?
No. This is one of the most dangerous myths in chicken farming. Dilution does not make spoilt cassava safe.
The cyanide and mycotoxins in spoilt cassava remain active even when mixed with other feed ingredients. Your chickens will still get poisoned. The effects might take longer to appear, making diagnosis harder.
Several farmers have told me they use this “dilution method.” Every single one experienced problems:
- Reduced growth rates
- Lower egg production
- Increased disease susceptibility
- Unexpected bird deaths
There is no safe way to use spoilt cassava. Period. The only safe option is proper disposal.
How Do I Find Reliable Cassava Suppliers in My Area?
Building relationships with good suppliers takes time. Here’s my approach:
Visit cassava farms directly: Talk to farmers. See their harvesting practices. Buy directly when possible.
Check garri processing centers: Look for clean facilities with good hygiene. Ask about their daily production. Arrange for fresh peel collection.
Ask other poultry farmers: Join local farmers’ associations. Share information about reliable suppliers.
Start small: Test new suppliers with small quantities first. Monitor your birds carefully. Scale up only if everything goes well.
I’ve worked with the same three suppliers for five years now. They understand my quality requirements. They call me when fresh cassava is available. This relationship saves me time and ensures consistency.
Final Thoughts: Success Through Safety and Quality
After eight years of farming and training hundreds of others, my message is clear: shortcuts in feed safety always cost more than they save.
Spoilt cassava be used as chicken feedย is not just a bad ideaโit’s a recipe for disaster. I’ve seen too many farmers learn this lesson the expensive way.
Good farming means:
- Using only fresh, high-quality ingredients
- Processing cassava properly and patiently
- Investing in good storage and equipment
- Learning from experienced farmers
- Never compromising on safety
Your chickens depend on you for everything. Feed them right. Keep them safe. Your business will thrive.
If you’re serious about using cassava in your feed program, start small. Get proper training. Visit successful farms. Learn the right way before investing heavily.
The potential savings are real. My farm proves this every month. But those savings only come from doing things correctly.
I hope this article helps you make informed decisions on your farm. If you have questions, ask experienced farmers in your area. Join agricultural programs. Keep learning.
Your success in chicken farming depends on many factors. Feed quality and safety rank among the most important. Get this right, and everything else becomes easier.
From my farm in Oyi to yours, wherever you are in Nigeria: farm smart, farm safe, and farm profitably.
Remember: Fresh cassava, properly processed = good for chickens and your wallet. Spoilt cassava = disaster waiting to happen.
The choice is clear. Make the right one for your birds and your business.
