Table 4 Body weight on the day before euglycemic hyperinsulinemic clamp test. Mean p-glucose (13 samples) and p-insulin (3 samples) during the last hour of clamp test, M-value (glucose consumption) and M/I-index (M-value correlated to the average insulin level) in 5 heifers fed low energy and protein (LO) and in 5 heifers fed high energy and protein (HI). Mean and SD within bars.
