Evaluasi Penambahan Premix Kombinasi Methane Inhibitor, Mineral Mix, dan Probiotik Pada Ternak Ruminansia Secara In Vitro

Abstract

Penelitian ini bertujuan untuk mengevaluasi premix kombinasi dengan campuran methane inhibitor berupa tanin, mineral mix, dan probiotik terhadap kecernaan, fermentabilitas, dan pengukuran gas metana. Penelitian ini menggunakan Rancangan Acak Kelompok dengan 12 perlakuan dan 5 ulangan. Variabel yang diamati adalah pH rumen, produksi gas total, produksi gas metana, kecernaan bahan kering, kecernaan bahan organik, dan N-NH3. Semua perlakuan menggunakan tanin cair kecuali L0 = tanpa penambahan dan L6 = dengan penambahan probiotik saja. Data dianalisis menggunakan analysis of variance (ANOVA) dan hasil yang signifikan (P<0,05) diuji lebih lanjut menggunakan uji kontras. Hasil penelitian menunjukkan bahwa penambahan tanin cair, probiotik, dan mineral organik berpengaruh nyata terhadap pH rumen, produksi total gas, produksi gas metana, kecernaan bahan kering, kecernaan bahan organik, dan N NH3. Kesimpulan dari penelitian ini adalah penambahan tanin cair, probiotik, dan tembaga akan menurunkan produksi gas total, produksi gas metana, kecernaan bahan kering, kecernaan bahan organik, dan N-NH3.

This study aimed to evaluate the premix combo with a mixture of methane inhibitors in the form of tannin, mineral mix, and probiotics on digestibility, fermentability, and measurement of methane gas. This study used randomized block design with 12 treatments and 5 replications. The observed variables were rumen pH, gas total production, methane gas production, dry matter digestibility, organic matter digestibility, and N-NH3. All of the treatments were used liquid tannin except for L0 = without addition and L6 = with additions probiotic only. Data were analyzed using analysis of variance (ANOVA) and significant results (P<0.05) were further tested using contrast’s test. The results showed that the addition of liquid tannin, probiotic, and organic mineral (Fe, Mn, Cu) had a significant effect on rumen pH, gas total production, methane gas production, dry matter digestibility, organic matter digestibility, and N-NH3. The conclusion of the research was the addition of liquid tannin, probiotic, and Cuprum would decrease total gas production, methane gas production, dry matter digestibility, organic matter digestibility, and N-NH3.
