TL;DRAbstract

Data from 9 balance experiments with lactating Jersey cows was used to evaluate the energetic efficiency of metabolizable energy utilization for milk production (kl). It has been demonstrated that kl values differ depending on the proportion between energy retained in fat (LFE) and protein (LPE) in milk. A new approach to calculate kl values according to the equation kl = 0.510 + 0.052 x LFE/LPE is presented.
