When you start with a weaner (a piglet that has just stopped suckling, usually at 2 months old), you are entering a race against the clock. Your goal is to get that pig to 70-80kg by the time it is 6 months old.
The spending follows a J-Curve:
Month 1 (The Purchase): High initial cost (buying the piglet).
Months 2-4 (Maintenance): Steady spending on feed and vaccines.
Months 5-6 (The Surge): This is where most farmers panic. As the pig gets bigger, its appetite explodes. A pig in month 6 eats nearly double what it ate in month 3.
Let’s look at a realistic estimate for raising 10 weaners to market weight in a Kenyan context. Note: Prices vary, but the proportions remain the same.
| Expense Item | Estimated Cost (KES) | Percentage of Total |
| Purchase of 10 Quality Weaners | 60,000 | 20% |
| Starter/Grower/Finisher Feed | 180,000 | 60% |
| Vaccines & Deworming | 10,000 | 3% |
| Water & Electricity | 5,000 | 2% |
| Labor (Self or Hired) | 15,000 | 5% |
| Emergency Fund (The “Just in Case”) | 30,000 | 10% |
| TOTAL INVESTMENT | 300,000 | 100% |
Your Breakeven Point is the price at which you neither make a profit nor a loss. To find this, you divide your total cost by the total kilograms of meat you expect to sell.
The Math:
If your 10 pigs reach 75kg each (Total 750kg) and your total cost was 300,000 KES:
This means if the butcher offers you 350 KES per kg, you are losing money. If he offers 450 KES, you are making a profit of 50 KES per kg (37,500 KES total profit).
The biggest risk in Africa is the fluctuation of grain prices. Drought or export changes can double the price of maize bran in a week.
The Rule of 10%: Always keep 10% of your total budget in a separate “locked” account (like an M-Shwari or a separate SACCO account). Do not touch this for repairs or personal emergencies. It is only for when the cost of feed rises or if a vet emergency occurs. If you don’t use it, that 10% becomes your bonus profit at the end of the cycle!
Farmer Omondi started with 20 pigs. He had enough money to buy the pigs and 4 months of feed. He figured he would “hustle” the money for the last two months later. In Month 5, the pigs were huge and eating 2.5kg of feed each per day. Omondi ran out of cash. To save the pigs from starving, he started feeding them only “Sukuma Wiki” (kale) and water. The pigs stopped growing and started losing weight. When he finally sold them in Month 8, they were thin and the meat was poor quality. He lost 100,000 KES.
The Lesson: If you only have money to feed 5 pigs properly for 6 months, do not buy 10 pigs. Half-feeding a pig is the fastest way to go broke.
FCR sounds like a big word, but it just means: “How many kilos of food does it take to make 1 kilo of meat?”
Good FCR (3:1): You give 3kg of food, you get 1kg of meat. (Profit zone!)
Bad FCR (5:1): You give 5kg of food, you get 1kg of meat. (Danger zone!)
To keep your FCR good, you must use quality feed (see Section 4) and prevent waste. If your pigs are trampling their food into the mud, you are literally throwing your cash flow into the dirt.
You don’t need a computer. A simple 20-shilling exercise book will do.
| Date | Item Bought | Quantity | Cost (KES) | Observations (Weight/Health) |
| 01/02 | Weaners (10) | 10 | 60,000 | Active, no coughing |
| 15/02 | Starter Feed | 4 Bags | 14,000 | Eating well |
| 01/03 | Dewormer | 1 Bottle | 1,200 | Administered to all |
Important things to keep in mind:
Pigs are not ATMs. You cannot withdraw money whenever you want. You must wait for the “maturity date.”
The Heavy Load is at the end. Budget more for feed in months 5 and 6 than you did for months 1, 2, and 3 combined.
Record every cent. If you buy a 50-cent nail for the pigsty, write it down. Small unrecorded costs are “leaks” that sink big ships.
