Pemanfaatan Enzim Lignoselulase untuk Mendukung Produktivitas Ternak Ruminansia; Sistematic Literature Review

Abstract

Lignocellulase is the main source of energy in ruminants. However, the nutritional value is still low and cannot be digested optimally. This study used the Systematic Literature Review (SLR) method which aimed to study the impact of administering lignocellulase enzymes to ruminants. This type of research is descriptive qualitative by taking data from relevant literature. The subjects and objects of the research are lignocellulosic enzymes and ruminants. This SLR uses PICOC to systematize tracing in journal reports, as the following populations; ruminant ruminant feed, intervention: lignocellulase enzymes, comparison: physical and chemical processing technology, results: lignocellulosic degradation, digestibility, context: animal nutrition. A literature search was carried out on the Scientdirect, PubMed, and Wiley pages. The search  found 185 articles. The results of the review show that the use of lignocellulase enzymes to increase the productivity of ruminants needs to be done with a combination of treatment and pre-treatment. Appropriate treatment will increase the digestibility of lignocellulosic nutrients and increase the amount of available nutrients that can be utilized by rumen microbes. Various enzymatic systems in the degradation mechanism are needed to ensure that each lignocellulosic component can be efficiently degraded which is the key to maximum energy harvest by ruminants.
