Abstract: The study examined the effect of limestone-urea mixture (LU) supplementation with different nitrogen (N): non fiber carbohydrate (NFC) ratio in the diet on feed digestibility and rumen fermentation characteristic in growing goat. Twelve Jawarandu local male goats with body weight average of 20.83±7.42 kg and aged at 4-6 months old were randomly distributed into four blocks based on their body weight and received three dietary treatments namely C12, LU12, and LU18. The C12 diet with 1:12 of N:NFC ratio and without LU supplementation, the LU12 diet with 1:12 of N:NFC ratio and LU supplementation, the LU18 diet with 1:18 of N:NFC ratio and LU supplementation. The LU was supplemented at 5% of total feed. The feed digestibility test was conducted after 12 weeks of feeding trial period and continued by determination of rumen fermentation characteristics. Intake (g/d) and digestibility of nutrients were unaffected by treatments. The experimental diet did not alter the rumen fermentation characteristics of goats; though, before feeding, the ruminal propionic acid concentration was higher (P<0.05) in LU supplementation groups than that in control group. The before feeding ratio of non-glucogenic to glucogenic volatile fatty acids were lower (P<0.05) in LU supplementation groups than that in control group. The supplementation of LU might increase dietary NFC availability in growing goats. The results of this study indicated that adding LU on diet could improve energy utilization by reducing the ratio of non-glucogenic to glucogenic volatile fatty acids.
