Abstract

This study aims to evaluate the effect of different types of additives and incubation periods for optimization of Total Mixed Fiber (TMF) silage. The method used in this study is randomized experimental design. The factorial pattern consists of 2 factors : additive type and incubation time. The treatment consists of Factor A type of additive: A1 = TMF ensilage with 7g sodium diacetate (SDA) / kg TMF A2 = TMF ensilage with 10x105 cfu lactic acid bacteria / kg TMF. Factor B incubation time B1 = ensilage with 21 days incubation time, B2 = ensilage with 30 days incubation time and B3 = ensiles with 45 days incubation time. The parameters measured are evaluation of nutritional value based on proximate analysis and Van soest. The result of this research indicates that there is an interaction between the types of additives and the duration of incubation in the ensilage optimization of total mixed fiber (TMF). In this study, it is found that the use of sodium diacetate gives the best results in the optimization of TMF silage until the incubation time of 45 days. The contents of TMF silage nutritional value with sodium diacetate (SDA) 7g/kg TMF as additive and 45 days incubation time are 83.79% dry matter, 86.62% organic matter, 12.65% crude protein, 17% crude fiber, 8.07% crude fat, 68.65% NDF, 58.78% ADF, 56% cellulose 34, 9.87% hemicellulose and 7.56% lignin
