-The flow indicator is defined as the fraction of the local yield that is utilized, expressed by its energy content [MJ NEL ha<sup>-1</sup> ]. Hence, it introduces a forage quality component to the yield calculation and allows for computing the energy balance combined with the energy demand indicator. Furthermore, losses due to grazing, harvesting and storage processes are considered.+The flow indicator is defined as the fraction of the local yield that is utilized, expressed by its energy content [MJ NEL ha<sup>-1</sup>  ].

   * <font 14px/inherit;;inherit;;inherit>The net yield is the amount of fodder that is actually consumed by livestock. When computing losses from gross yield to net yield, the specific storage and feeding techniques used have a major impact. Losses during storage and feeding account for anywhere between 5% and 40% (Buchgraber 2004, p. 49). Due to the fact that these factors depend on individual farm management, mean values are used to calculate the deduction: as a total mean, 15% will be deducted for all losses.</font>   * <font 14px/inherit;;inherit;;inherit>The net yield is the amount of fodder that is actually consumed by livestock.
