The TMR Mineral Mismatch

The TMR Mineral Mismatch
8/3/2017

Action plan for implementing precision feeding.

Goals

Validate mixing procedures and ingredient specifications by analyzing the total mixed ration at least two times per year.

Steps

  • Step 1: Determine key times during the year when TMR sampling would be appropriate.
  • Step 2: Record batch weights, refusals and the number of cows fed when the TMR is sampled.
  • Step 3: Calculate the actual dry matter intake based on the batch weights and the dry matter percent of the TMR.
  • Step 4: Compare the TMR analysis with the formulated ration. Discuss any discrepancies with the nutritionist and feeder.
  • Step 5: Record milk production and intakes. Make notes of any events that may have affected results.

Monitoring must include an economic component to determine if a management strategy is working or not. For the lactating cows income over feed costs is a good way to check that feed costs are in line for the level of milk production. Also included are the feed costs for dry cows, springing heifers, pregnant heifers and growing heifers. To read the full article, click here.
