Abstract
This research was conducted to determine the performance of male Bali Cattle fed diet in differentcontent of protein and energy. The Randomized Completely Block Design(RCBD) was used in thisexperiment, which consisted of five treatments and three weight groups as replication. The body weight ofmale Bali cattlewas used range from198.67 to 207.00kg. Fifth treatment is composed of five rations withdifferent protein and energy content as follows: A) protein rations with 15.42% and gross energy )GE) 4.02Mcal/kg DM; B) protein rations with 14.74% and GE 3,75 Mcal/kg DM; C) protein rations with 13.11% andGE3.79 Mcal/kg DM; D) protein rations with 10.33% and GE 3.92 Mcal/kgDM; and E) protein rations with10.58% and GE 3.53 Mcal/kg DM. The variables measured were nutrient intake,digestibility rations,bodyweight again and feed conversion ratio (FCR).The results showed that thedry matter intake, organicmatter, crude fiber, energy consumption, organic matter, crude protein and crude fiber digestibility showedno significant differences (P>0.05), while the consumption of crude protein and crude fat in treatmentAwas significantly higher (P<0.05) than treatment E. The dry matter digestibility was highest incattlereceivingtreatmentA(65.83 vs 44.41%) than treatment E. Thebody weight gainwas highestin cattlesreceiving treatment A (0.56vs0.32 kg/d) than treatment E, whereasFCRin cattle receiving treatment Aislower(8.98 vs. 16.58) than treatment E. In conclusion the growth of bali cattle in ration with 15.42% and GE 4.02Mcal/kg DM the highest and most efficiently utilize feed.

Summary
Pemeliharaan sapi bali di tingkat petani umumnya masih dilakukan secara tradisional dan bersifat sambilan. Pakan yang diberikan kepada sapipun mengandalkan pada hijauan, terutama rumput-rumputan alami yang adaserta belum memperhatikan jenis pakan dan nutrien yang terkandung di dalamnya. Protein dan energi merupakan nutrisi penting yang harus diperhatikan dalam menyusun ransum untuk ternak pemamah biak/ruminansia. Kandungan protein dan energi ransum sangat menentukan efisiensi pemanfaatan nutrisi yang akhirnya berpengaruh pada produktivitas ternak.Oleh karena itu, formula ransum dengan nutrien yang cukup dan seimbang dapat menghasilkan produktivitas ternak sesuai dengan potensi genetiknya. Berdasarkan uraian tersebut,bila pakan yang diberikan hanya hijauan saja tanpa memperhatikan kandungan nutrien pakan maka pertambahan bobot badan ternak rendah. Oleh karena itu perlu dilakukan penelitian tentang sapi bali jantan yang diberi ransum dengan protein dan energi yang berbeda, agar diperoleh produktivitas ternak yang optimal. Tujuan penelitian ini adalah untuk mengetahui pengaruh protein dan energi ransum terhadap pertumbuhan sapi bali jantan
