Digestibility In Vitro Discorea Hispida Dennst using Albizia Saponaria Lour Extract as Local Feed

Abstract

The availability of local feed resources in various regions in Indonesia is quite abundant in quantity and availability, but their utilization is not optimal. This study specifically analyzes the In Vitro Digestibility of Dioscorea hispida Dennst Using Albizia Saponaria Lour (Langir) Extract as local feed, which was carried out at two locations, namely Tinanggea District, Konawe Selatan Regency, and the animal feed laboratory, Faculty of Animal Science, Halu Oleo University with a research duration of 6 months, namely January-July 2023 The study used a completely randomized design (CRD) unidirectional pattern with 4 treatments and 4 replications so that a total of 16 experimental plots. The experimental procedure begins with preparing Dioscorea hispida Dennst, the preparation of langir bark extract, the Soaking of the Trial Samples, and the Collection and Sampling. The findings showed that using langir bark extract up to 15% reduced cyanide acid (HCN) levels to 10,07 ppm or 49,06% compared to HCN levels in the study controls. Langir bark extract up to 15% usage level in Dioscorea hispida Dennst immersion has no effect on dry matter digestibility and organic matter digestibility in vitro because it still shows the maximum digestibility level of 91,54-93,48% dry matter and 69,74-77,86% organic matter, langir bark extract into Dioscorea hispida Dennst flour was used effectively in improving the concentration of NH3 and VFA at the 5% level, with the achievement of a concentration of NH3 of 5,09 mM and a concentration of VFA of 147,10 mM.
