Overview

Crossover study demonstrates that corn silage supplementation enhances energy-corrected milk production in grazing dairy cows, indicating reduced body mass mobilization.

Key Points

  • Supplementing grazing cows with corn silage and protein increased energy-corrected milk yield while reducing grazing time and body mass mobilization.
  • Cows receiving corn silage and protein produced 4.5 kg/day more energy-corrected milk, whereas corn silage alone increased yield by 2.5 kg/day.
  • Crossover design evaluation revealed shifted ruminal fermentation without altering reticular pH, highlighting trade-offs in nitrogen use efficiency.
