Planning a feeding program? This calculator estimates a starting daily feed ration based on body weight.
Daily Feed (kg) = Body Weight(kg) x (Feed % of Body Weight / 100)
Example
A 500 kg animal, 2.5% of body weight reference feeding rate:
Daily Feed = 500 x 0.025 = ~12.5 kg/day
Where the 2-3% Reference Range Comes From
A commonly cited reference dry matter intake for many livestock species is roughly 2-3% of body weight per day, a general starting point used across ruminant and other livestock nutrition planning.
Why This Varies So Much by Production Stage
This varies significantly by species, production stage (growth, lactation, maintenance, late gestation), and feed quality - a lactating or rapidly growing animal typically needs a higher percentage than one in simple maintenance, so a livestock nutritionist or veterinarian can refine this baseline for your specific herd and production goals.
