This study aims to examine the fiber content of liquid feed made from tamarind seeds due to different fermentation times. This research has been carried out for eigth months, namely from July 2020 – February 2021 which takes place in the Nutrition and Feeding Labolatory of the Kupang State Agricultural Polytechnic. This study used whole tamarin seeds from the South Central Timor area and feed ingredients in the from of bran, corn, meat and bone meal, and soybean meal. The variables analyzed in this study were the content of the fiber fractions consisting of ADF, NDF, Cellulose, Hemicellulose, and Lignin. This study used a completely randomized desing (CRD) consisting of 4 treatments and 5 replications as follows: (R0) liquid feed with 0 days of fermentation (without fermentation), (R1) liquid feed with fermentation time 7 days, (R2) liquid feed with fermentation timeb of 14 days, (R3) liquid feed for 21 days, (R4) feed with of for 28 days. Data were analyzed using analysis of variance (Anova) and Duncan’s test. The results of this study showed that the length o liquid feed fermentation significantly effect (p<0,05) to the fiber fraction. It is recommended to carry out liquid feed fermenteation with a water ratio of 7 days and be tested on pigs to determine the growth response. Keywords : ADF, NDF, Cellulose, Hemicellulose, Lignin
