Milk protein %

3.3% average

Protein as a percentage of milk — usually the higher-value solid, and a sensitive marker of the herd’s energy status. Recorded at herd test or continuously on milk meters.

The benchmark

Australian herds average about 3.4% protein; the typical range is 3.2–3.6%.

DataGene Herd Improvement ↗
What it signals

Protein responds mainly to dietary energy: low protein test usually means cows are short of energy, not protein. It tracks closely with body condition and is a quiet early warning of an under-fed herd.

Data required to calculate
Milk protein producedkgTotal milk volumeL

Silo pulls each of these from the sources the operation already uses, and keeps the figure current automatically.

How to improve it
01

Lift dietary energy density with quality pasture and balanced concentrates.

02

Maintain body condition so cows aren’t milking off their backs.

03

Match supplement to the energy gap rather than feeding crude protein.

Questions & answers

What is milk protein %?

Protein as a percentage of milk — usually the higher-value solid, and a sensitive marker of the herd’s energy status. Recorded at herd test or continuously on milk meters.

What data do you need to calculate milk protein %?

You need: Milk protein produced (kg), Total milk volume (L). Silo pulls each of these from the sources the operation already uses and keeps the figure current automatically.
