« Ahhh if only cows could talk and tell us what is wrong! »  Well, believe it or not, we're getting there! While the basic milk components already provide a lot of information to help us to optimize the rations that our cows eat, the milk fatty acid profile can clarify a lot about herd rumen health.  The interpretation of PROFILab analysis can help you to better adjust rations and feed management practices in your herd.

What is PROFILab?

PROFILab is what we discover when we take a more in depth look at the « fat » component of milk, and listen to what your cows are telling us.

Each of the four groups of fatty acids can tell us something different:

  • De novo: these fatty acids are made in the mammary gland. They are indicators of good rumen health. We want these to be high!
  • Mixed: These can be made in the mammary gland, but they can also come from the diet. They usually follow the de novo or preformed fatty acids, except when palm oil based feeds are fed, in which case they go up to the detriment of the other groups.
  • Preformed: as their name implies, they are already formed before they get to the milk. Therefore, either the cow eats them, or they come from the mobilization of fat reserves. Are the preformed high? There might have been a change in feeds or feed intake,  or the cows might be losing weight.
  • Polyunsaturated: is the form in which fatty acids are found in forages and concentrates. The cow transforms them in the rumen. Therefore, if levels are high in the milk, it suggests that cows are eating a lot (for example: going out to pasture) or that there is a problem in the rumen (example: acidosis)
