RUFAL: What it IS and What it is NOT – Dr. Tom Jenkins

RUFAL – What it IS

RUFAL stands for Rumen Unsaturated Fatty Acid Load and is a number meant to show the total unsaturated fatty acid level entering the rumen from all feeds consumed each day. It was designed to be a better indicator of fermentation disruption in the rumen than just relying on the percentage of fat added to the diet.

RUFAL – What it is NOT

RUFAL is NOT a perfect indicator of when a herd will have milk fat depression. Rather, if a herd IS having milk fat depression, RUFAL values can be evaluated to determine if high levels of unsaturated fatty acids should be included as a possible risk factor.
