Feeding supplements

Tactical feeding decisions this spring-summer should be made based on the marginal milk response to supplement fed and the $ returns that you might expect from this investment.

It is critical to understand the difference between marginal and average milk responses.

  • Marginal milk response is the incremental increase in milk yield obtained from an extra kg of supplement fed
  • Average milk response is the increase in milk yield averaged across all kgs of supplement fed.
