ABSTRACT

This study aimed to evaluate the nutritional value of complete fed based on corns stover and king grass on Holstein Friesians (HF) Dairy cattle. Twenty-one HF (2.5-3.5 years old, weighted 250-300 kg) was adapted for 2 weeks by feeding with experimental feed. The experimental feed was formulated into three combinations: T1 (70% corn stover+0% king grass+30% concentrate; T2 (35% corn stover+35% king grass+30 % concentrate; T3 (0% corn stover+70% king grass+30% concentrate. Fecal of HF was collected every day for ten weeks after adaptation. Dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber digestibility (ADFD), NH3 synthesis and efficiency of microbial protein synthesis were analyzed. The highest dry matter digestibility (DMD), organic matter digestibility (OMD), neutral detergent fiber digestibility (NDFD), NH3 concentration and efficiency of microbial protein synthesis (ESPM) were found in T2 group (64.04%, 65.05%, 60.63%, 189.36 mg.L-1, and 24.10 gr N.kg-1. BOTR-1, respectively). While the highest ADF was found in the T3 group (56.37%). The study suggested that T2 group produce the highest nutritional value compared to other combinations. The high level of the protein content of corn stover was proven to increase microbial protein synthesis in the rumen.
