Tamarind seeds have a high energy content but have limited use for pigs because the seed coat is tough and contains anti-nutrient tannins. Therefore, liquid feed fermentation technology is carried out. The aim of this research was to assess the gross energy, digestible energy and metabolizable energy content of liquid feed fermentation (Lff) with different fermentation time in growing pigs. The research materials were whole tamarind seeds, bran, corn, meat and bone meal, and soybean meal. The study used a completely randomized design and consisted of 5 treatments and 5 replications. Treatment = Lf0: Lff time 0 days; Lf1: Lff for 7 days, Lf2: Lff for 14 days, Lf3: Lff for 21days, Lf4: Lff for 28 days fermentation. The research variables were the energy content of the ration and the prediction of digestible energy and metabolic energy value. Data were analyzed using analysis of variance and Duncan's advanced test. The results showed that the fermentation of liquid feed containing tamarind seeds with different fermentation time had a significant effect (P<0.05) on the gross energy content, digestible energy, and metabolic energy. The best gross energy content, digestible energy, and metabolic energy at the fermentation time of 14 days, respectively 4,835 ± 64.74 Kcal / kg, 3.041 ± 99.16 Kcal / kg, and 2,974 ± 99.60 Kcal / kg. It was concluded that the time for fermentation of liquid feed containing tamarind seeds which can produce good energy content and prediction of digestibility and metabolic energy is 14 days
