This study aims to get the balance of energy and protein rations of dairy cows on feed consumption, digestibility and milk production. This study used a completely randomized design (CRD) 2x2 factorial pattern with 3 replications. The treatment factor used is the ration energy content (TDN) for factor A, namely: Al (65%), A2 (70%) and ration protein content for factor B, namely: Bl (14%), B2 (16%). The variables observed in this study include dry matter consumption (DMC), organic matter consumpt.ion (OMC), dry matter digestibility (DMD), organic matter digestibility (OMD), crude protein digestibility (CPD) and milk production. The results showed that there was an interaction between energy and protein rations on dry matter consumption (KBK), organic matter consumption (KBO), dry matter digestibility (KcBK), organic matter digestibility (KcBO) and milk production. The conclusion of this study is that feeding with a balance of 70% energy and 14% protein in the ration gives a significantly different effect on Dry Material Consumption (KBK) of 14.88 kg/head/day, Organic Material Consumption (KBO) of 13.41 kg/head/day, Digestibility of Dry Material (KcBK) of 69.18%, Digestibility of Organic Material (KcBO) of 71.29%, Milk Production of 19,98 liters/head/day not 9,98 liters/head/day.
