About the Livestock Feed Calculator
Feed is the largest single cost in most livestock operations, so estimating it accurately is essential for budgeting, purchasing, and storage. This calculator estimates daily and monthly feed needs from your animal type, head count, and average body weight, using standard dry-matter intake percentages.
How Feed Requirements Are Calculated
Animals eat a fairly predictable share of their body weight each day:
Daily feed per head = average weight × (intake % ÷ 100)
| Livestock type | Daily intake (% of body weight) | Typical crude protein |
|---|---|---|
| Beef cattle | ~2.5% | ~11% |
| Dairy cattle | ~3.0% | ~16% |
| Broiler poultry | ~5.0% | ~22% |
| Layer poultry | ~4.0% | ~16% |
| Pigs (grower) | ~4.5% | ~16% |
| Sheep | ~3.0% | ~12% |
| Goats | ~3.5% | ~14% |
Multiply per-head feed by head count for the herd total, and by 30 for a monthly estimate.
As-Fed vs Dry Matter
Intake percentages are typically expressed on a dry-matter basis. Wet feeds such as silage contain a lot of water, so the as-fed weight you actually deliver is higher. Always reconcile rations on a dry-matter basis, and remember that clean water — often several times feed weight per day — is just as critical to intake and performance.
Why It Matters
Underfeeding cuts growth, milk, and reproduction; overfeeding wastes expensive feed and can cause metabolic problems. A solid estimate lets you contract feed, size storage, and plan grazing. For production diets, confirm rations with a livestock nutritionist and forage testing, since requirements shift with growth stage, lactation, and weather.
Livestock Nutrition and Feed Rations
Profitable livestock operations rely on precise feed management. Whether raising beef cattle, dairy cows, or poultry, feed represents the highest input cost for a farmer. Rations must be formulated to meet the animal's exact energy, protein, and mineral requirements without wasting expensive supplements. Our Livestock Feed Calculator helps determine daily Dry Matter Intake (DMI) and bulk feed requirements based on the herd size and target weight gains.
Dry Matter vs. As-Fed
The fundamental concept in livestock feeding is the difference between 'As-Fed' and 'Dry Matter' (DM). All feeds contain moisture. Pasture grass might be 80% water, while dry hay is only 10% water. However, the nutritional value (protein, energy) is entirely in the dry matter. Ruminants (cattle, sheep) consume feed based on a percentage of their body weight in Dry Matter (usually 2% to 3%). A farmer must mathematically convert the Dry Matter requirement back into 'As-Fed' pounds to know exactly how much wet silage or pasture the animals actually need to consume to meet their nutritional needs.
Frequently Asked Questions
How much feed does a cow need per day?
Beef cattle eat roughly 2.5% of body weight in dry matter daily — about 30 lb for a 1,200 lb cow. Dairy cows eat more, around 3%.
What is dry-matter intake?
It is feed intake measured with the water removed. Because wet feeds like silage hold a lot of moisture, the as-fed amount delivered is larger than the dry-matter figure.
Does feed requirement change with production stage?
Yes. Growth, late pregnancy, lactation, and cold weather all raise requirements, while maintenance needs are lower.
How much water do livestock need?
Water needs usually far exceed feed weight and rise with heat, lactation, and dry rations. Constant clean water is essential for intake and performance.
