Fat-protein quotient
The fat-protein quotient describes a variable with which a conclusion about the health of the dairy cow is possible.
background
Since the energy metabolism of the cows cannot be covered in the early lactation after calving , cows are at risk of disease during this time and can e.g. B. suffer from ketosis , abomasum displacement or ovarian cysts . Since these diseases can occur insidiously, it is necessary to use a size in order to recognize these animals at an early stage and to treat them accordingly. The parameters fat and protein are already recorded by the milk yield test and are therefore easily available for a calculation. The normal physiological range is between 1.1 and 1.5. In animals with a fat-protein ratio outside the normal range, an increased loss rate was found.
