ABSTRAK
Penelitian dengan tujuan untuk mengetahui pengaruh penggunaan rumput laut merah (Eucheuma
cottonii, ECOT) terhadap pemanfaatan energi pada pedet sapi Bali lepas sapih dini. Sebanyak 16
ekor pedet sapi bali dengan kisaran berat badan sekitar 30-40 kg yang disapih dini pada umur 3-4
bulan. Penelitian ini mengikuti rancangan acak kelompok berdasarkan berat badan dengan 4
perlakuan dan 4 ulangan. Adapun perlakuan yang diberikan adalah pakan komplit dengan
kandungan ECOT berturut-turut 0% (CT0), 5% (CT5), 10% (CT10) dan 15% (CT15). Hasil
penelitian menunjukkan bahwa penggunaan ECOT 10 dan 15% pada ransum menurunkan (P<0,05)
konsumsi gross energi dan energi tercerna dan meningkatkan kehilangan energi melalui urin.
Penggunan ECOT hingga 15% dalam ransum komplit tidak mempengaruhi (P>0,05) kehilangan
energi melalui feces dan kecernaan energi serta konsumsi energi termetabolis (ME) pada pedet sapi
Bali yang disapih dini. Dapat disimpulkan bahwa penggunaan ECOT hingga 15% tidak dapat
meningkatkan pemanfaatan energi pakan oleh pedet sapi Bali lepas sapih, bahkan menurunkan
konsumsi GE dan DE.
Kata Kunci: Eucheuma cottonii, partisi energi, sapih dini, pedet sapi Bali.
ABSTRACT
The aim of this experiment was to determine the effect of the use of red seaweed (Eucheuma cottonii,
ECOT) on energy utilisation in early weaned Bali calves. A total of 16 calves with a body weight
range of about 30-40 kg and weaned early at the age of 3-4 months were used in the present
experiment. This study followed a randomized block design based on body weight with 4 treatments
and 4 replications. The treatments were complete feed containing ECOT at a level of 0% (CT0), 5%
(CT5), 10% (CT10) and 15% (CT15), respectively. Results showed that the use of ECOT at 10 and
15% in the ration decreased (P <0.05) the gross energy and digestible energy intake but increased
energy loss through urine. The use of ECOT up to 15% in the complete ration did not affect (P>
0.05) the energy loss through feces and energy digestibility as well as the metabolizable energy
(ME) intake in early weaned Bali calves. It can be concluded that the use of ECOT up to 15% cannot
increase the utilization of feed energy by the early weaned Bali calf, even reducing the intake of GE
and DE.
