Calculating Livestock Feed Requirements
Feed based on body weight: cattle 2.5%, dairy 3.5%, horses 2%, sheep/goats 3-3.5%.
Needs vary by stage: pregnant +10-15%, lactating +30-50%, growing needs higher protein.
These are rough estimates. Actual rations should be formulated by a nutritionist based on forage quality.
Frequently Asked Questions
How much does a cow eat?
1000 lb cow eats about 25 lbs dry matter daily (2.5% body weight).

Dry matter removes moisture. Fresh pasture is 80% water, so 100 lbs grass = 20 lbs dry matter.
