Theory

The Z-Box is a particle separation device to determine the physical effectiveness factor (pef) of a forage or TMR using an “as fed” sample on farm. In conjunction with the sample NDF, peNDF can be determined through the equation pef x NDF = peNDF.

peNDF is an important means for monitoring effective fiber in dairy rations to ensure rumen health. Traditionally pef has been determined by sieving a dry sample with vertical motion using a Tyler RoTap shaker device.

The Z-Box particle separator was developed in cooperation with ZEN-NOH, Japan’s National Federation of Agricultural Co-operative Associations.
