Why Corn Silage Matters

Corn silage is a high-energy forage crop that provides excellent feed value for dairy and beef cattle. Proper timing of harvest and management practices can significantly impact both yield and quality, directly affecting livestock performance and farm profitability.

Optimal Harvest Timing

🌽 1/2 Milk Line

65-70% Moisture

Optimal for most situations. Good balance of yield, quality, and ensiling characteristics.

🌾 3/4 Milk Line

60-65% Moisture

Higher starch content, good for high-producing dairy cows. May need moisture adjustment.

🌱 Black Layer

55-60% Moisture

Maximum starch, but lower digestibility. Risk of poor fermentation if too dry.

Variety Selection

Leafy Varieties

  • • Higher fiber digestibility
  • • More leaf area for photosynthesis
  • • Better for dairy operations
  • • Slightly lower starch content

Conventional Varieties

  • • Higher grain-to-stover ratio
  • • Maximum starch content
  • • Good for beef operations
  • • Traditional plant architecture

Factors Affecting Yield

Agronomic Factors

  • Plant population and spacing
  • Soil fertility and pH
  • Nitrogen availability
  • Water management

Environmental Factors

  • Growing degree days
  • Rainfall distribution
  • Temperature stress
  • Soil type and drainage

Quality Factors

Energy

Starch content increases with maturity
Fiber digestibility decreases over time

Protein

7-9% crude protein typical
Higher in leafy varieties

Fiber

NDF 40-50% of dry matter
Digestibility key factor

Ensiling Process

  • Chop length: 10-19mm for proper packing and processing
  • Pack immediately to exclude oxygen
  • Achieve proper density: 15-18 lbs DM/cubic foot
  • Cover and seal within 24 hours
  • Allow 21-day fermentation before feeding
  • Monitor temperature during fermentation
