Populasi Mikroba Rumen, Fermentabilitas, dan Kecernaan Suplementasi Daun Kelor dalam Ransum Sapi Perah secara In Vitro

This study aimed to evaluate the microbial rumen population, fermentability, and digestibility of Moringa leaf supplementation in dairy cow ration using vitro determine optimal level supplementation. The experiment consist two steps with first step was microbiology measurement used a Randomized Block Design 5 treatments extract (P0= control; P1= 5%, P2 = 10%, P3 =15%, P4 =20%) second fermentability 7 (R0 control, R1 R0 + 2.5% leaf, R2= +5% R3 7.5% R4= R0+10% R5=R0+12.5% R6=R0+15% leaf) which grouped by fluids. Data analysis variance continued Duncan’s Multiple Range Test. measured variable were population (bacteria protozoa), (N-NH3, VFA), protein synthesis, dry matter (DMD), organic (DMO). results showed significantly decreased bacterial (p<0.05), but there no effect on protozoa population. did not affect N-NH3, DMD, DMO, influenced VFA concentration synthesis (p<0.01). higher decreasing total concentration, still within normal range for fermentation (102.29-126.69 mM). quadratic an at range. It can be concluded supplemented up ration.
