Livestock & Feed Calculators

Free calculators for feed ration building, dry matter intake estimation, feed conversion tracking, hay planning, and water requirements. Every tool uses NRC-sourced data and practical formulas for reliable estimates.

Feed Ration Builder

Build feed rations with multiple ingredients and see nutrient totals on a dry-matter basis with CP, TDN, and NDF breakdown.

Dry Matter Intake (DMI) Estimator

Estimate daily dry matter intake based on species, body weight, and production level using NRC standards.

Feed Conversion Ratio (FCR) Calculator

Calculate feed conversion ratio and cost per kg of gain with benchmark comparison for your species.

Hay & Bale Needs Calculator

Estimate bales needed for winter feeding based on herd size, feeding days, bale type, and waste factor.

Livestock Water Needs Calculator

Calculate daily, monthly, and annual water requirements by species, head count, and temperature range.
