Feed-quantity arithmetic
Use your own dry-matter, as-fed, forage-share, and concentrate-share assumptions without treating a ratio as a formulated ration.
Verify feed, health, welfare, and local requirements before using an estimate in practice.
The calculator converts entered dry-matter quantity to as-fed quantity using the entered dry-matter percentage, then divides that total by the entered forage and concentrate percentages. It does not evaluate nutrient adequacy or feed safety.
Ten 500 kg animals at a 2.5% entered dry-matter intake produce 125 kg dry matter. At 50% dry matter, the model shows 250 kg as-fed; a 70% forage share displays 175 kg forage and 75 kg concentrate.

No. Ratios do not assess protein, energy, minerals, fibre, feed quality, or an animal's needs.
Use an appropriate current analysis or verified farm record; the tool does not provide or validate it.
No. It does not balance nutrients or prescribe feed.
No. Every quantity, quality, cost, and measurement value is entered locally.

No. Feed analysis, water, health, welfare, stage, weather, and local conditions can materially change outcomes.
No. Verify a real decision with current records and a qualified livestock or nutrition professional.
No. Check relevant welfare, feed, medication, and local requirements independently.
