Cattle Weight Estimator (Heart Girth & Length)
Accurately estimate live cattle weight using standard USDA tape measurement formulas (heart girth circumference and body length) without a livestock scale.
Cattle Water Requirement Calculator
Calculate daily herd water requirements across cattle classes (lactating cows, dry cows, bulls, feeders) and extreme summer temperatures, plus trough sizing and peak flow rates.
Cattle Gestation & Calving Date Calculator
Calculate exact calving dates, dry-off deadlines, ultrasound pregnancy check dates, and pre-calving vaccination schedules based on breeding date and breed-specific gestation lengths.
Target Calving to Breeding Date Calculator
Work backwards from your ideal target calving date to find the exact date you must turn out bulls or schedule artificial insemination (AI).
Breeding Season & Heat Cycle Planner
Calculate estrus cycle return windows (18–24 days), pregnancy diagnosis dates, bull breeding capacity ratios, and synchronization protocols.
Ranch & Cattle Unit Converter
Instantly convert ranch & livestock units: acreage to hectares, pounds to kilograms, gallons to liters, $/cwt pricing, forage yields, and weather measurements.
Bull Cost Per Calf Weaned & Longevity Calculator
Calculate the true lifetime sire cost per cow exposed, cost per calf weaned, and sire cost per pound produced, comparing natural service against artificial insemination (AI).
