Evaluasi Pakan Silase Total Mixed Ration Terhadap Kecernaan dan Fermentabilitas Rumen Sapi Perah

Abstract

Penelitian ini bertujuan untuk mengevaluasi dan membandingkan kecernaan serta fermentabilitas in vitro pada rumen sapi perah antara variasi pakan silase Total Mixed Ration (TMR). Penelitian menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 5 ulangan berdasarkan variasi pakan berupa pakan rumput gajah dan konsentrat rasio 70:30 (P1), silase Total Mixed Ration (P2), silase TMR perlakuan dengan Lactobacillus plantarum (P3), silase TMR perlakuan dengan rumput gajah 10% (P4), silase TMR (Total Mixed Ration) NH3, Kecernaan Bahan Kering (KcBK), Kecernaan Bahan Organik (KcBO) serta produksi gas total. Data dianalisis dengan metode ANOVA, apabila berbeda nyata diuji lanjut dengan uji Duncan SPSS versi 25. Hasil penelitian menunjukkan pakan setiap perlakuan memiliki nilai yang berbeda nyata terhadap kadar NH3, KcBK, KcBO, dan produksi gas total sedangkan pakan dan variasi pakan TMR tidak berpengaruh nyata terhadap pH. Dapat disimpulkan bahwa penggunaan pakan TMR tanpa variasi pakan terbaik dalam kecernaan.

This study aims to evaluate and compare the digestibility and in vitro fermentability in the rumen of dairy cows between variations of Total Mixed Ration (TMR) silage feed. The study used a completely randomized design with 5 treatments and 5 replicates based on feed variations in the form of elephant grass feed and concentrate ratio 70:30 (P1), silage Total Mixed Ration (P2), silage TMR treatment with Lactobacillus plantarum (P3), silage TMR treatment with 10% elephant grass (P4), silage TMR (Total Mixed Ration) treatment with 10% concentrate (P5). Parameters tested included pH, NH3 levels, Dry matter digestibility (KcBK), Organic matter digestibility (KcBO) and total gas production. The results showed that the feed of each treatment had significantly different values on NH3 levels, KcBK, KcBO, and total gas production while TMR feed and feed variation had no significant effect on pH. It can be concluded that the use of TMR feed without feed variation is best in digestibility.
