PENGARUH BERBAGAI ARAS PEMBERIAN POLLARD TERHADAP KOMPOSISI TUBUH DOMBA LOKAL

Abstract

ABSTRAK Sebuah penelitian yang ditujukan untuk mengetahui perubahan komposisi tubuh domba lokal aid bat pemberian pollard sebagai sumber protein dalam ransum telah dilakukan dengan menggunl'.kan 12 ekor domba lokal, umur I tahun dengan berat 23 kg. Penelitian ini dilaksanakan selama 10 minggu menggunakan Rancangan Acak Lengkap (RAL) dengan 3 aras pemberian pollard dan 4 ulangan, yaitu; kontrol (0%; PO), 25 (P25) dan 50% (P50) dari kebutuhan bakan kering (4% bobot badan). Selama penelitian berlangsung temak diberi pakan basal berupa rumput gajah secara ad libitum. Pengukuran komposisi tubuh dilaksanakan dengan metode 'urea space' pada minggu ke I dan ke 10. Hasil penelitian menunjukkan bahwa pemberian pollard dalam pakan sebanyak 25 dan 50% konsumsi bahan kering memberikan peningkatan pada protein tubuh kosong maupun lemak tubuh kosong. Dapat disimpulkan bahwa pemberian pollard sebagai sumber protein druam pakan sampai dengan 50% dapat meningkatka komposisi tubuh domba lokaL Kata kunci: komposisi lubuh, domba lokal, pollard ABSTRACT Research on the effect of pollard feeding as a source of protein on body composition was carried out using twelve indigenous rams aged one year old and weighed 23 kg. During 10 weeks experimental period, the animals were treated with three levels of pollard feeding, i.e., control (0%; PO), 25 (P25) and 50% (P50) of dry matter requirement, complied with Completely Randomized Design (CRD), while the Napier grass was fed ad libitum. Tht: feed was adjusted to meet the dry matter requirement at 4% of live weight. During the experimental periods, body composition was measured by 'urea space' method, at week 1 and 10. Results ofthe experiment indicated that feeding polhrd as much as 25 and 50% ofdry matter intake were followed by increasing both empty body protein and empty body fat. !t was concluded that providing pollard as a protein source in the diet at 50% could be used to improve body composition of local sheep.
