Abstract:

Key Points

 A method combining bite-count on target animals and F.NIRS was developed.

 Direct continuous observation of target goats recorded botanical composition of diets and handplucked forage representing bites was used to determine chemical and botanical composition.

 Fecal samples collected on the second and third day following observations were mixed to develop diet-fecal pairs with the hand plucked diet.

 Botanical composition calibrations of 2 browse species and total herbaceous forage were reasonable with R2 between 0.77 – 0.89 and SECV between 5.6 – 7.8% DM.

 Calibrations for CP, NDF, in vitro DM digestibility would reliably predict diets of goat browsing in this environment. Calibrations for PEG binding tannins can only be used for screening purposes.

 Calibrations for DM intake were poor.
