Effect of changing the glucose content in the DMI on the time of first ovulation after calving. Hormonal cycles were simulated over the lactation period for different fractions of glucose in DMI (parameter c₀). Simulated data (red dots), which represents the estimated incidence of first ovulation, is determined by the time of first LH peak followed by an increase in progesterone production above baseline. The blue line represents the fitted curve f(x)=a· exp(−b·x)+c to the data with a=45581, b=0.30317, c=35.644. A lower glucose content results in a late ovulation, whereas a higher glucose content results in an early ovulation
