At a glance: Milk fat accounts for a significant share of available metabolic energy. Those who reduce the fat content in a targeted way create reserves for fertility and animal health—without impairing milk yield.
Why milk fat costs so much energy
The synthesis of milk fat is one of the most energy-intensive processes in the dairy cow’s metabolism. For each kilogram of milk with a 4% fat content, around 3.3 MJ are required—at 3.5%, it is only 3.0 MJ.
This difference may seem small, but with a daily yield of 35–40 kg of milk it adds up to several MJ per day—energy the animal then lacks elsewhere, especially for fertility.

CLA as a targeted solution
Conjugated linoleic acids (CLA) specifically inhibit the enzymes involved in milk fat synthesis in the mammary gland. Milk fat content decreases in a controlled manner—milk volume remains unchanged.
The energy saved is immediately available to the animal: for recovery after calving, for ovarian function, and for a successful pregnancy.
The form of administration is crucial: Only rumen-protected CLA (as in BEWI®-FATRIX CLA) reach the small intestine unchanged and can fully develop their effect there.
