Summary

Feeding high amounts of wheat to dairy cows reduced milk yield. Supplementing with protected amino acids or increased rumen escape protein did not fully restore milk production, suggesting protein utilization issues.

Area of Science:

  • Animal Science
  • Dairy Nutrition
  • Ruminant Physiology

Background:

  • Wheat is increasingly used in dairy rations.
  • High inclusion of wheat can impact nutrient utilization and milk production.
  • Understanding protein metabolism in cows fed wheat is crucial.

Purpose of the Study:

  • To evaluate the effects of increasing wheat inclusion in dairy cow rations.
  • To assess the impact of protected amino acids and rumen escape protein on milk yield in wheat-based diets.
  • To investigate protein utilization in dairy cows fed high-wheat diets.

Main Methods:

  • Two trials were conducted with dairy cows fed varying levels of hard red winter wheat.
  • Rations included 0, 40, or 60% wheat with sorghum silage.

  • Second trial compared 60% wheat diets with a corn-based control, with or without protected amino acids and increased rumen escape protein.

    • Main Results:

    • Dry matter (DM) and crude protein (CP) intake were unaffected by wheat inclusion or supplementation.
    • Milk yield decreased linearly as wheat content increased in Trial 1.
    • In Trial 2, wheat-based diets, even with supplementation, resulted in lower milk yield compared to the control or supplemented wheat diet.

    Conclusions:

    • High inclusion of wheat in dairy cow rations negatively impacts milk yield.
    • Protected amino acids and increased rumen escape protein did not fully compensate for the reduced milk yield associated with high wheat diets.
    • The reduced performance appears linked to altered protein utilization in cows fed high-wheat rations.
