Summary, etc	El consumo de forraje por el ganado en pastoreo, segun el ejemplo de las vacas lecheras, depende del tiempo y la tasa de pastoreo, una funcion del tamano del bocado y de la tasa del mismo. Se registraron tiempos de pastoreo prolongados (de hasta 720 min en 24 horas) cuando las vacas pastaron en praderas tropicales, especialmente en praderas maduras, y una alta proporcion del pastoreo se registro durante las horas de oscuridad. Las mediciones del comportamiento de consumo (bocados) brindan una medida mas precisa del comportamiento de alimentacion que el tiempo de pastoreo, debido a la gran variacion en la intensidad de pastroreo. Los bocados del animal reflejan la facilidad de prension, mientras que la rumia indica calidad; el no. total de los 2 tipos de bocado en 24 horas varia de 25.000 en forraje de buena calidad hasta 75.000 en praderas tropicales de baja calidad. Estas medidas indican que las vacas tenian dificultad para satisfacer sus requerimientos nutricionales cuando pastaban en algunas praderas tropicales. El tamano del bocado es uno de los principales determinantes del consumo. En praderas tropicales vario desde 0,05 - 0,60 g de MO/bocado, con un tamano critico del bocado de 0,3 g de MO/bocado. La disponibilidad de hojas y la facilidad de alcance del forraje, asi como la densidad foliar y de la pradera fueron factores importantes que determinaron el tamano del bocado. El tamano del bocado mas grande (0,81 g de MO/bocado) se obtuvo con avena inmadura; con Chloris gayana y Setaria anceps se presento una disminucion notoria en el tamano del bocado a medida que aumentaba la madurez. El tamano del bocado de Macroptilium atropurpureum cv. Siratro fue menor que el de Digitaria decumbens y S. anceps debido a una mejor disponibilidad de las gramineas. (Extracto)
