Spanish; Castilian. En el campo del Instituto de Zootecnia, Nova Odessa, SP, se realizo un estudio con el cv. Coloniao IZ-1 (Panicum, maximum Jacq.) para medir la produccion de heno en cuatro edades; de corte (51, 65, 79 y 93 dias). El diseno utilizado fue bloques al azar con cuatro repeticiones. Se evaluaron la produccion de MS, los tenores de proteina bruta (PB), la fibra en detergente neutro (FDN), los porcentajes de lamina foliar y de tallo, y la curva de deshidratacion. Las variaciones en estos parametros fueron:producciones de MS (t/ha) = 3.48-7.716; concentracion de PB = 8.83%-4.65% y FDN = 83.67%-87.12%; porcentaje de lamina foliar (por edad en dias) = 58.76% (51), 52.26% (65), 45.74% (79) y 45.50% (93); porcentaje de tallo (por edad) 41.24% (51), 47.14% (65)54.26% (79) y 54.20% (93). La curva de deshidratacion presento tendencia lineal a la reduccion con el tiempo de exposicion (Y = 76.6240 - 4.422OX, r2 = 0.9825).

Hay production of Panicum maximum IZ-1, cut at four different ages (51, 65, 79, and 93 days of growth) was evaluated at the Instituto de Zootecnia in Nova Odessa (Sao Paulo, Brazil). A randomized block experimental design was used with 5 replications. Dry matter yield/ha, protein content, NDF, and stem/leaf ratio were evaluated. The water loss curve was also established. Dry matter production ranged from 3,484 to 7,716 kg/ha; crude protein from 8.83 to 4.65; NDF from 83.7 to 87.1; and water loss presented a linear curve depending on period of exposure (Y = 76.6240 - 4.4220X, R2=0.9825.
