Livestock Calculators — Agriculture
Herd and flock management: calving dates, cattle weight estimation from measurements, egg production, and aquaculture feed rates. Weight estimation by tape measurement is the practical option when no scale is available on farm.
All Livestock Calculators
Calculate feed amounts for fish farming based on species, weight, and water temperature.
Estimate calving date from breeding or AI date for cattle.
Estimate cattle weight using heart girth and body length tape measurements.
Estimate weekly and annual egg production from flock size, breed, and season.
Estimate egg production from flock size, lay rate, and seasonal factors.
Calculate expected birth date for farm animals — cows, horses, pigs, sheep, and goats.
Calculate daily feed requirements for goats by body weight, production stage, and breed.
Calculate the number of beehives for honey production from target yield and location.
