Penelitian bertujuan mengetahui efek suplemenlasi kompleks mineral-minyak dan mineral- organik dalam ransum terhadap kecernaan nutrien ransum, populasi mikroba rumen, performa produksi dan pola pertumbuhan domba jantan lokal Penelitian dilakukan secara eksperimen dengan Rancangan Acak Lengkap (RAL) empat perlakuan dan empat ulangan lerhadap 16 ekor domba lokal jantan berbobot badan rataan 19,5 + 1,9 kg. Perlakuan terdiri alas R1 = ransum basal + 5%minyak kacang tanah (MKT), R2 = Ransum basal + 5% Suplemen Ca-MKT + 5% Suplemen I-MKT, R3 = Ransum basal + 3% Suplemen (Zn-organik + Cu-oganik) dan R4 = Ransum basal + 3% (Zn-organik + Cu-organik) + 5% Ca-MKT + 5% I-MKT. Hasil penelitian menunjukkan bahwa kecernaan serat kasar ransurn pada domba yang diberi suplemen minyak kacang tanah utuh (R1) Iebih rendah (P<0,05) dari R2, R3 dan R4 (53,8% vs 63,1%, 67,0%, dan 70,7%); sedangkan kecernaan Iemak kasar ransum R1 lebih tinggi (P<0,05) dari RZ, R3, R4 (61,6% vs 36,4%, 38,6% dan 57,0%). Kecernaan bahan kering dan bahan organik ransum, serta populasi mikroba rumen lidak dipengaruhi oleh perlakuan. Jumlah konsumsi bahan kering ransum dan pertambahan bobot badan harian pada R1 Iebih rendah (P<0,05) dari R2, R3 dan R4 sedangkan konversi ransum pada R1 Iebih tinggi (P<O,05) dari RZ, R3 dan R4. Disimpulkan bahwa sintesis kompleks minyak kacang tanah oleh mineral kalsium dan lodium meningkatkan kecernaan ransum dan performan produksi domba, Penggunaan kompleks mineral-minyak dan mineral organik baik secara sendiri maupun gabungan memiliki efek yang sama terhadap kecernaan ransum dan performan produksi domba.

The objective of this study was to evaluate the effect of supplementation with organic- mineral and oil-mineral complex to ration on nutrient digestibility, mmen microbial population, production performances and daily weight gain rate of ram. The experimental was arranged in Completely Randomized Design (CRD), there were four treatments and four replications. Sixteen rams (19.5 + 1.9 kg live weight) were randomized into 16 individual pens. The treatments were R1 = basal ration + 5% peanut oil, R2 = basal ration + 5% Ca-peanut oil complex + 5% I-peanut oil complex, R3 = basal ration + 3% (Zn-organic + Cu-organic) and R4 = basal ration + 3% (Zn-organic + Cu-organic) + 5% Ca-peanut oil complex+ 5% I-peanut oil complex. The results showed that digestibility of ration crude fiber in R1 was lower (P<0.O5) than RZ, R3 and R4 (53_B% vs. 63,1%, 67.0% and 70.7%), but digestibility of ration extract ether in R1 was higher (P<O.O5) than R2 R3 and R4 (61,6% vs. 36.4%, 38.6% and 57.0%), The ration dry matter and organic matter digestibility and rumen bacteria and protozoa population of rar-n fed R1, R2, R3 and R4 not affected, respectively, Feed consumption and average daily weight gain in R1 was lower (P<0,05) than R2, R3, and R4, but feed conversion in R1 was higher than R2, R3 and R4. lt was concluded that the synthesis of salt peanut oil-Ca or salt peanut oil-l could improve digestibility and performance of ram. Utilization of mineral-oil complex or mineral organic had same effect on digestibility and production performance of ram.
