Abstract:

Key Points

 F.NIRS determines relative differences between diets accurately on most samples. However, unless calibrations are developed on the same diets as samples to be predicted, the predictions will provide only approximate values of the percent of a plant in the diet.

 Microhistological analysis of fecal samples is less accurate than F.NIRS and cannot be used to develop calibrations or monitor calibration performance.

 Calibration equations can be enhanced by increasing the diet diversity fed with the target plant.

 Guidelines for conducting a feeding trial to create diet-fecal pairs include - Air dried target plants can be used in feeding trials. - Two to three levels of a target plant plus zeros are adequate for calibration. - Diets should be fed for 4 days before collecting fecal samples. - Sex of animal affects calibrations.
