SUPLEMENTASI PADA PAKAN BASAL TUMPI JAGUNG DAN KULIT KOPI TERHADAP KINERJA DOMBA JANTAN MUDA

Abstract

The purpose of this research is to study feed supplementation source of protein and energy at basal feed pulp coffe and tumpi corn on feed comsumption, average daily gain, feed conversion, biological value and nitrogen balance. Six teen rams weighing on average 15 - 25 kg (approximately 10-12 month old) were panned individually in the wooden-slatted cage were use in this experiment, arrange in Random Block Complied Design 4 x 4 with 4 treatment and 4 block. Composition of basal feed were corn tumpi dan coffe pulp (ratio 80 : 20) and the feed supplement were dry onggok and consentrate (ratio 50 : 50) with crude protein = 22%. The treatments applied were R0 (Elephant grass : Basal feed : Feed Supplement = 30% : 30% : 40%), R1 (Basal feed : Feed Supplement = 40 % : 60%), R2 (Basal feed : Feed Supplement = 60% : 40%) and R3 (Basal feed : Feed Supplement = 30% : 70%). The variable observed in this research were the dry matter intake (DMI), organic matter intake (DMO), crude protein intake (CPI), average daily gain (ADG), feed convertion, biological value and nitrogen balance. The result indicates that the average of feed intake (DMI, DMO, CPI), and average daily gain (ADG), biological value and nitrogen balance was very significantly different (P<0,01). The usage of Ransum R2 (Basal feed : Feed Supplement = 60% : 40%) tended to increased performance rams
