Abstract

In this study, we developed a calibration equation to determine the feed composition and fermentative quality of non-powdered barley whole-crop silage. Near-infrared spectroscopy (NIRS) analysis could be used to predict the concentrations of dry matter (DM) (R²_v = 0.93 ; ratio of performance to deviation [RPD] = 3.6), crude protein (CP) (R²_v = 0.86 ; RPD = 2.6), crude fat (R²_v = 0.77 ; RPD = 1.8), acid detergent fiber (ADFom) (R²_v = 0.85 ; RPD = 2.4), neutral detergent fiber (R²_v = 0.44 ; RPD = 1.4), lactic acid (R²_v = 0.89 ; RPD = 2.7), acetic acid + propionic acid (R²_v = 0.87 ; RPD = 2.4), butyric acid + valeric acid (R²_v = 0.85 ; RPD = 2.6), total volatile fatty acid (VFA) (R²_v = 0.86 ; RPD = 2.7), and total acid (R²_v = 0.88 ; RPD = 2.4), volatile basic nitrogen (VBN) content (R²_v = 0.88 ; RPD = 2.7), and pH value (R²_v = 0.87 ; RPD = 2.6). The results obtained in this study indicated that the concentrations of DM, CP, ADFom, lactic acid, butyric acid, acetic acid+propionic acid, butyric acid+valeric acid, total VFA, and total acid, VBN content, and pH value in barley whole-crop silage can be predicted with an acceptable accuracy using NIRS techniques.
