Feasibility of use of total mixed ration feed containing fermented trembesi leaves

Abstract

This study aims to determine the level of fermented trembesi leaves in the Total Mixed Ratio (TMR) ration that can be given to ruminants. This research will be carried out at the Animal Feed Science Laboratory, Department of Animal Feed Nutrition, Faculty of Animal Husbandry, Gadjah Mada University for 5 months, from June 2022 to November 2022. This study determines the digestibility of forage using in vitro gas production measurements using the Menke and Steingass method with PEG administration. There are 8 treatment levels of adding tamarind leaves in TMR, namely T0 = TMR without fermented tamarind leaves, T1 = TMR containing fermented tamarind leaves (5%) of the total forage given, T2 = TMR containing fermented tamarind leaves (10%) of the total forage provided. given, T3 = TMR containing fermented tamarind leaves (15%) of the total fermented forage, T4 = TMR containing fermented tamarind leaves (20%) of the total given forage, T5 = TMR containing fermented tamarind leaves (25%) of the total forage given, T6 = TMR containing fermented tamarind leaves (30%) of the total given forage, and T7 = TMR containing fermented tamarind leaves (5%) of the total given forage. Each treatment was repeated 3 times. The data for the determination of the chemical composition were analyzed for variance using a completely randomized design (CRD) in a unidirectional pattern. If there is a significant difference as the effect of the treatment, it is continued with Duncan's new multiple range test (DMRT). The research concluded that the addition of fermented tamarind leaves up to 35% of the total mix ration (TMR) can be given to ruminants. and the best treatment on TMR containing trembesi leaves of 35% with a digestibility of BK of 26.31.
