Energy requirement for primiparous Holstein × Gyr crossbred dairy cows

Energy requirement for primiparous Holstein × Gyr crossbred dairy cows

ABSTRACT: Our objective was to estimate the requirements of metabolizable energy (ME) and NEM of lactating and dry cows, the efficiency of ME utilization for milk production (kl) and tissue gain (kg), and the use of body energy mobilization for milk production (kt) throughout the lactation of primip...
