How to Use This Calculator

Enter the number of dairy cows in your operation and their average weight (default: 1400 lbs). Adjust the daily feed percentage of body weight if needed, then enter the feed price per ton to see daily, monthly, and annual feed costs.

Why This Matters

Feed is the largest ongoing expense for dairy cows operations. Accurately projecting feed requirements prevents both shortages that hurt animal performance and overbuying that wastes capital. With a typical FCR of 1.4-1.6:1 (lbs milk/lb feed), every improvement in feed efficiency directly boosts profitability.

Methodology

Daily feed = Average weight × Feed percentage (3.5% of body weight). Annual feed = Daily feed × 365 days. Annual cost = (Annual feed / 2000) × Price per ton. The 3.5% default is a standard guideline for dairy cows and should be adjusted for production stage and environment.

Common Mistakes to Avoid

  • Using a single average weight for all dairy cows when weights vary significantly by age and condition.
  • Not adjusting feed percentage for production stage — lactating, growing, and finishing animals have different needs.
  • Forgetting that feed wastage (typically 5-15%) adds to the actual amount you need to purchase.
  • Projecting annual costs from a single month without accounting for seasonal price and consumption changes.

Tips & Best Practices

  • High-producing cows need 3.5-4% of body weight in dry matter.
  • TMR (total mixed ration) ensures consistent nutrition.
  • Fresh, clean water intake directly correlates with milk production.
