Livestock Feed Calculator
Calculate base feed requirement, feed including waste, total feed cost, and period cost per animal. The feed-store visualization separates feed expected to be consumed from the additional quantity purchased for the entered waste allowance.

How to use Livestock Feed Calculator
- Define the animal group and obtain an appropriate daily as-fed allowance from a qualified ration or management plan.
- Enter the expected feeding period and a waste allowance supported by bunk, storage, weather, and handling observations.
- Compare the purchase tonnes and cash requirement with storage capacity, delivery size, forage inventory, and feed quality.
Calculator guide
Understanding Livestock Feed Calculator
A bulk feed budget converts animals, daily allowance, feeding days, waste, and price into tonnes and period cost. It does not formulate a nutritionally complete ration, so quantity planning and animal nutrition remain separate decisions.
Calculation method
How the calculation works
Multiply animals, daily allowance, and days, then add the entered waste allowance and price the total feed mass. Multiply animal count by feed per animal per day and feeding days for base feed. Multiply base feed by one plus waste percentage for purchase quantity, multiply by price per kilogram for cost, and divide cost by animal count for period cost per animal.
Inventory planning
Translate tonnes into a delivery plan
A season total still needs to fit storage, shelf life, and delivery operations.
Worked situations
Practical examples
- Eighty-five animals at 7.5 kg/day for 90 days require 57,375 kg before waste.
- An 8% allowance increases the purchase requirement to 61,965 kg.
- At $0.42/kg, the modeled period cost is about $26,025, or roughly $306 per animal.
Better inputs
Useful tips
- Keep dry-matter and as-fed quantities distinct; moisture can make equal wet weights nutritionally different.
- Measure refusals and storage loss instead of using a permanent generic waste percentage.
- Separate feed categories when animals receive different rations or prices.
Before relying on the result
Limitations and common mistakes
- The calculator budgets one uniform feed quantity and price for every animal and day.
- Dry matter, energy, protein, minerals, forage quality, animal weight, production stage, health, and substitution between feeds are not modeled.
- Mortality, herd movement, price changes, delivery fees, inventory carrying cost, and storage-capacity constraints are excluded.
Reference
Key terms
- As-fed weight
- Feed weight including its current moisture content.
- Dry matter
- Feed remaining after water is removed; commonly used for nutritional comparison.
- Feed waste allowance
- Additional purchase quantity intended to cover storage, handling, bunk, or refusal loss.
- Animal-day
- One animal fed for one day; animal count multiplied by feeding days.
Important note
Calculated from the entered field and production values. Confirm seed-lot data, equipment calibration, labels, local conditions, and applicable agronomic guidance.
Frequently asked questions
Should feed allowance be entered as dry matter?
Use the same basis for allowance and price. If the ration is planned on dry matter but feed is bought as-fed, convert moisture consistently before using the calculator.
Does waste percentage include refusals?
It can if that is how the operation defines and measures loss, but storage, handling, and bunk refusals may be better tracked separately.
Why is cost per animal not cost per day?
The displayed value covers the full entered feeding period. Divide by days for an average daily figure if the herd remains constant.
Can this calculator balance a ration?
No. Nutrient requirements and feed analysis require a dedicated ration-balancing process and professional oversight.
