Evaluasi daun lamtoro dan kaliandra segar dengan silase terhadap kualitas fisik, kimia, dan biologis in-vitro.

Abstract

Penelitian ini bertujuan untuk mengetahui perbandingan kualitas daun lamtoro dan kaliandra yang di silase dengan tanpa silase terhadap sifat fisik, kandungan kimia, dan kecernaan secara in-vitro. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) faktorial 3x2 sebanyak 5 ulangan. Faktor A : T1 = tanpa silase, T2 = silase 30 hari dan faktor B : P1 = daun lamtoro 100%, P2 = daun kaliandra 100%, dan P3 = 50% daun lamtoro : 50% daun kaliandra. Peubah yang diamati dalam penelitian ini: karakteristik fisik silase, DBK, DBO, NH3, VFA total, gas total, populasi protoza isotricha, entodinium, diplodinium, total protozoa, total bakteri, nilai pH, BK, BO, PK, SK, LK, NDF, dan ADF. Hasil penelitian menunjukan bahwa kualitas fisik, kimia, dan kecernaan biologis daun lamtoro dan daun kaliandra dapat dipengaruhi oleh proses silase dan perbedaan komposisi hijauan. Proses silase dan komposisi hijauan memiliki interaksi yang dapat meningkatkan kualitas fisik aroma dan tekstur, kandungan BK dan PK, serta meningkatkan DBK dan DBO, namun dapat menurunkan kualitas warna, kandungan SK, VFA total, dan populasi protozoa isotricha. Nilai pH dan populasi total protozoa menurun karena proses silase, perbedaan komposisi hijauan berpengaruh terhadap kandungan BO, LK, NDF, ADF, konsentrasi NH3 dan produksi gas total.

This study aims to determine the comparison of the quality of lamtoro and calliandra leaves in silage and with no silage on physical properties, chemical content, and digestibility in-vitro. The experimental design used complete randomized design (CRD) factorial 3x2 with 5 replicates. Factorial A : T1 = without silage, T2 = 30 days silage and factor B: P1 = 100% lamtoro leaves, P2 = 100% calliandra leaves, and P3 = 50% lamtoro leaves : 50% kaliandra leaves. The variables observed in this study are: physical characteristics of silage, Degradability of dry matter, Degradability of organic matter, VFA, gas prodution, population of protoza isotricha, entodinium, diplodinium, total protozoa, total bacteria, pH, dry matter, Ash, organic matter, crude protein, crude fiber, crude fat, NDF, and ADF. The results showed that the physical, chemical, and biological digestibility of lamtoro leaves and calliandra leaves can be influenced by the silage process and differences in forage composition. Silage process and forage composition have interactions that can increase the physical quality of aroma and texture, dry matter and crude protein content, and increase Degradability of dry matter, Degradability of organic matter, but can reduce the quality of color, crude fiber content, total VFA, and isotricha protozoa population. The pH value and total protozoa population decreased due to the silage process, differences in forage composition affected the content of organic matter, crude fat, NDF, ADF, NH3 concentration and total gas production.
