Chicken Feed Calculator
Feed accounts for 65% to 75% of the total cost of poultry production in Zambia. Whether you are raising broilers for meat in Chibombo or managing a layer flock for eggs in Lusaka, accurately estimating your feed requirements is critical for profitability. This Chicken Feed Calculator helps poultry farmers estimate daily and monthly feed consumption, calculate total feed costs, and determine how many standard 50kg bags you need to purchase.

Understanding Poultry Feed Consumption in Zambia
Chickens eat different amounts of feed depending on their age, breed, and purpose. Broilers are bred to grow rapidly and consume large amounts of high-protein feed in a short time (usually 5 to 6 weeks). Layers, on the other hand, eat less per day but require a steady, balanced diet over a much longer period (up to 72 weeks) to maintain egg production. The calculator above uses standard average consumption rates for commercial hybrid breeds (like Cobb 500 for broilers and Lohmann/Isa Brown for layers) commonly used in Zambia.
Standard Feed Consumption Rates
The calculator uses the following average daily intake rates per bird. Note that these are estimates; actual consumption can vary based on temperature, feed quality, and management practices.
| Chicken Type | Growth Stage | Avg. Daily Intake per Bird |
|---|---|---|
| Broiler | Starter (0-14 days) | ~30 grams |
| Grower (15-28 days) | ~100 grams | |
| Finisher (29-42 days) | ~160 grams | |
| Layer | Pullet (9-18 weeks) | ~60 grams |
| Layer (19+ weeks) | ~115 grams |
Understanding Feed Conversion Ratio (FCR)
For broiler farmers, the Feed Conversion Ratio (FCR) is the most important metric for profitability. FCR measures how efficiently a chicken converts feed into body weight.
Example: If your broilers eat 4.5 kg of feed to reach a market weight of 2.5 kg, your FCR is 1.8. A lower FCR is better. Commercial broilers in Zambia typically achieve an FCR between 1.5 and 1.8. If your FCR is above 2.0, you are losing money on wasted feed.
Tips to Reduce Feed Wastage
Feed wastage can silently destroy your profit margins. In Zambia, where feed prices fluctuate with the cost of maize and soya, every gram counts. Implement these practices to minimize waste:
- Adjust Feeder Height: The rim of the feeder should be at the same height as the bird’s back. If it’s too low, they will scratch and spill it. If it’s too high, they will struggle to reach it.
- Don’t Overfill Feeders: Fill feeders only one-third to one-half full. Overfilling encourages birds to scratch and spill feed onto the litter.
- Control Pests: Rats and mice can consume and contaminate up to 10% of your stored feed. Ensure your feed store is rodent-proof and use bait stations around the perimeter.
- Proper Storage: Store feed bags on wooden pallets, away from walls, in a cool, dry place. Feed exposed to moisture develops aflatoxins (a deadly fungus common in Zambian maize/soya), which will stunt growth and cause liver damage.
Frequently Asked Questions
How much feed does a broiler eat in its lifetime?
A standard commercial broiler raised to 6 weeks (42 days) will consume approximately 4.0 to 4.5 kg of feed in its lifetime. This is usually divided into roughly 0.5 kg of Starter, 1.5 kg of Grower, and 2.5 kg of Finisher feed.
Can I mix my own feed instead of buying commercial bags?
Yes, many large-scale farmers in Zambia mix their own feed using maize, soya, lime, and premixes. However, you must have a reliable lab (like the University of Zambia’s vet lab or private labs) to test your raw materials for protein content and aflatoxins. If the nutritional balance is slightly off, your birds will not grow or lay eggs efficiently.
Why are my layers eating more feed but laying fewer eggs?
This is a common issue. It could be due to several factors: the feed protein/calcium levels are too low, the birds are stressed (heat stress is common in October), there is a disease outbreak (like Newcastle or Infectious Bronchitis), or the lighting program in the coop is incorrect (layers need 16 hours of light to maximize production).
How long can I store 50kg bags of chicken feed?
Commercial pelleted or mash feed should be used within 3 to 4 weeks of the manufacturing date printed on the bag. The vitamins and medications in the feed degrade over time. Never use feed that is more than 2 months old, as it loses its nutritional value and risks mold growth.
