Objective: This study aimed to determine the effects of different feed restrictions and refeeding on feed intake, digestibility, body weight gain and feed cost in goats. Materials and Methods: There were three treatment groups of goats had an average initial body weight of 20-25 kg. Control goats (R0) were fed 3.5% Dry Matter (DM) of body weight or underwent 1 month of feed restriction treatment (R1) and 2 months (R2) of 60% restrictions (DM base). After the restriction period, R1 and R2 groups were fed ad libitum. The variables measured include Dry Matter Intake (DMI), Organic Matter Intake (OMI), Crude Protein Intake (CPI), body weight gain, Dry Matter Digestibility (DMD), Organic Matter Digestibility (OMD), Crude Protein Digestibility (CPD) and feed cost. Data were analyzed using ANOVA based on a Completely Randomized Design (CRD) on SPSS program version 21 for windows. Results: Feed restriction had a significant effect on body weight gain, the DMI, OMI, CPI and feed cost. However, the treatments did not significantly affect body weight or DM, OM and CP digestibility. Conclusion: One month of feed restriction continued with 2 months of re-feeding (R1) can lead to compensatory growth such that the average daily gain is the highest.
