Fermentabilitas Dan Kecernaan Pakan Komplit Yang Mengandung Enzim Dan Probiotik Pada Ternak Domba Secara In Vitro
The national meat self-sufficiency program proposed by the government aims to boost sheep productivity, but it may have negative environmental implications due to increased levels of metabolic production, fermentability, and digestibility, leading to higher greenhouse gas emissions from the livestock sector. Additionally, the prevalence of macro and micro nutritional deficiencies in livestock contributes to low productivity, highlighting the need for new feed formulations to enhance rumen fermentation characteristics and promote environmentally friendly metabolism. One potential solution involves incorporating feed additives such as enzymes and probiotics. The purpose of this study is to assess the efficacy of utilizing feed supplements such as enzymes and probiotics in complete feed, based on type and composition, to enhance the productivity of ruminant livestock by improving the rumen fermentation profile and generating environmentally sustainable fermentability and digestibility metabolic products through in vitro experiments. A Completely Randomized Design (CRD) with 4 treatments was employed in this research: untreated ration feed (P0), ration feed + 0.6 µl protease enzyme (P1), ration feed + 12.5 µl L. plantarum probiotics (P2), and feed ration + 0.6 µl protease enzyme + 12.5 µl probiotic L. plantarum (P3). The results of the study indicated that the inclusion of 0.6 µl of protease enzyme (P1) in the rations significantly raised the NH3 concentration, total VFA, and the percentage of DMD and OMD in comparison to the other treatments.
Key findings: digestibility, enzyme, fermentability, nh3, probiotic
