The FiMLAC Protein Story - Part 1

Compound feeds and blends are traditionally formulated to the crude protein content and we all talk about an “18%” cake” or “24% blend” being needed.  But this tells us nothing about how the cow will actually use that protein.

The rationing models we use on farm ration the cows to metabolisable protein - i.e., the protein the cow will be able to utilise.  Is this not how we should formulate the feeds, too?

Well, uniquely, Massey Feeds do...

The Feed into Milk project gave us three new names for the different types of metabiolisbale protein (MP) found in each feed:

  • MPB:    by pass protein
  • MPN:    by pass protein plus the potein made in the rumen from the rumen degradable nitrogen available in the diet
  • MPE:    by pass protein plus the protein made in the rumen from the rumen available energy (starches, sugars, fibre and oil)

Each is added up individually in the diet and whichever of the MPN and MPE is lowest is taken as the amount the cow will be able to use – usually the MPE value. A bit like making bacon sandwiches!

Each feed has values already known to us and they are shown on our silage analyses.  Once the ration is calculated, there are three questions to ask:

  1. Have I got enough MPE to meet the requirements for the milk I want the cows to produce?
  2. Is this in line with the metabolisable energy (ME) supply in the diet?
  3. How much excess MPN do I have?
