Abstract

Estimates of milk constituents by Fourier-transform mid-infrared (FTIR) analysis offer a promising tool in identifying dairy cows experiencing excessive energy deficit (EED) in early lactation. Our objectives were to describe the diurnal variation of FTIR estimates of milk fatty acids (FA) and the effect of hyperketonemia on this variation.
