Penelitian ini bertujuan untuk mengevaluasi pengaruh level protein konsentrat  FML dan dua jenis pakan basal terhadap kecernaan nutrien meliputi, kecernaan Neutral Detergent Fiber (KcNDF), kecernaan Acid Detergent Fiber (KcADF), dan kecernaan hemiselulosa (KcHM), kecernaan protein kasar (KcPK), kecernaan bahan kering (KcBK), kecernaan bahan organik (KcBO), dan In Vitro True Digestibility (IVTD) secara in vitro. Penelitian menggunakan Rancangan Acak Lengkap (RAL) pola faktorial 2 × 2 dengan 4 ulangan. Faktor pertama adalah dua level protein kasar (PK) konsentrat (protein rendah dan protein tinggi) dan faktor kedua adalah jenis pakan basal, jerami padi (Oryza sativa) dan rumput gajah (Pennisetum purpureum). Metode fermentasi rumen menggunakan in vitro Daisy Incubator^II (Teknologi ANKOM) selama 48 jam dan jika hasil interaksi signifikan dilanjutkan dengan uji Tukey. Hasil analisis ragam menunjukkan bahwa peningkatan level protein konsentrat FML menurunkan KcNDF, KcADF, KcBK dan KcBO (P<0>0,05). Rumput gajah memiliki KcHM, KcBK, KcBO, dan IVTD (P<0>0,05). Tidak terdapat interaksi nyata (P>0,05) terhadap parameter fraksi serat (KcNDF, KcADF, dan KcHM), yang terjadi karena tingginya amonia ransum sehingga mengganggu kecernaan fraksi serat. Sebaliknya, terdapat interaksi yang sangat nyata (P<0>

This study aimed to evaluate the effects of different levels of FML protein concentrate and different types of basal feed on nutrient digestibility, including Neutral Detergent Fiber (NDF) digestibility, Acid Detergent Fiber (ADF) digestibility, hemicellulose digestibility (HcD), crude protein digestibility (CPD), dry matter digestibility (DMD), organic matter digestibility (OMD), and in vitro true digestibility (IVTD). This study was designed using a Complete Randomized Design (CRD) with a 2 × 2 factorial pattern and 4 replicates. The first factor was two levels of crude protein (CP) in the concentrate (low-protein and high-protein), and the second factor was the type of basal feed, namely rice straw (Oryza sativa) and elephant grass (Pennisetum purpureum). Rumen fermentation was conducted using an in vitro Daisy Incubator II (ANKOM Technology) for 48 hours, and if interaction effects were significant, Tukey’s test was performed. Analysis of variance results showed that increasing the protein level of the FML concentrate reduced NDF, ADF, DMD, and OMD (P < 0> 0.05). Elephant grass had higher HcD, DMD, OMD, and IVTD (P < 0> 0.05). There was no significant interaction (P > 0.05) for the fiber fraction parameters (NDF, ADF, and HcD), which occurred due to the high ammonia content in the diet, thereby interfering with the digestibility of the fiber fractions. Conversely, there was a highly significant interaction (P < 0>
