    • 1) Producción de pasto/m2 = 2,1 Kg. FV/m2
      2) Desperdicio de pasto 30%.
      3) Área de pastoreo 50m2
      4) %MS obtenida en laboratorio = 20 %
      5) CFV. 2.1K (ofrecido)–0.63K (desperdicio)/m2=1.47K/m2.
      6) Consumo total de forraje verde.
      1.47K/m2 x 50m2/vaca/día = 73.5KFV.
      7) Consumo de materia seca.
      100K. FV 20 Kg. M.S
      73.5K. FV X = 14.7K de M.S
      8) La vaca necesita para mantenimiento 17,27 k.cal/KPV.
      Para una vaca de 500 K = 8.6 M.cal EM.m.

      9) La energía de una pradera = 2.5 M.cal/K.MS
      10) Aporte energético por el consumo de MS.
      = 2.5Mcal/K. x 14.70= 36.75 Mcal.
      11) Para producir un litro de leche con 3.5% de grasa, se
      necesitan. = 1.2 Mcal.
      12) Tenemos entonces que:
      13) 36.75Mcal – 8.6 Mcal = 28.15 M.cal
      14) Energía sobrante para producción:
      Base forrajera = 28.15 M.cal/1.2 M.cal = 23.45 litros
