| Abstract | Abstract. This study was designed to examine the effects of supplementation with husk extract of garlic (Allium sativum) in the feed of dairy goats containing sufficient amount of ÃÂàorganic minerals (Selenium, Chromium and Zinc) on the fermentation and microbes in the rumen. The materials used in this study were the rumen fluid of goat, goat ration composed of 60% grass, 35% tofu, and 5% concentrate (CP 11.90%, CF 28.57%, 60.94% TDN). The research method was experimental using a completely randomized design (CRD). The treatments were tested, namely R0: control diet; R1: R0 + Cr + 1.5 ppm 40 ppm Zn lysinat + 0.3 ppm Se; R2: R1 + 15 ppm ÃÂàof garlic husk extract (Allium sativum); R3: R1 + 30 ppm garlic husk extracts ; R4: R1 + 45 ppm ÃÂàof garlic husk extrat; and R5: R1 + 60 ppm ÃÂàgarlic husk extract. The results showed that the treatment effect on a decrease in dry matter (DMD) and ÃÂàorganic matter digestibility (OMD), protozoa and total gas in total, however, there was an increase in total VFA concentrations. The treatment gave a linear response to the DMD, ie Y = 50.412 - 0.1651XÃÂàand OMD,ÃÂàY = -0.1768X + 50.319. However, in response VFA is cubic, with a line equation Y = 203.16 - 3.2646X + 0.2447X2- 0.0033X3. It culd be concluded that ÃÂàsupplementation of garlic husk extract and organic minerals can improve rumen fermentation with the best level at 25 ppm.Key words: ÃÂàGarlic husk extract, micro minerals, rumen fermentation, dairy goatÃÂàAbstrak.ÃÂàPenelitian ini dirancang untuk mengkaji pengaruh suplementasi ekstrak kulit bawang putih (Allium sativum) dalam pakan kambing perah yang tercukupi mineral organik (Selenium, Chromium dan Seng) terhadap hasil fermentasi dan mikrobaÃÂàpada rumen. Materi yang digunakan adalahÃÂàcairan rumen kambing, ransum kambing yang tersusun atas 60% rumput gajah, 35% ampas tahu dan 5% konsentrat (PK 11,90%, SK 28,57%, TDN 60,94%). Metode penelitian adalah eksperimental menggunakan Rancangan Acak Lengkap (RAL).ÃÂàPerlakuan yang diujicobakan yaitu R0: pakan kontrol; R1: R0 + 1,5 ppm Cr + 40 ppm Zn lysinat + 0,3 ppm Se; R2: R1 + 15 ppm ekstrak kulit bawang putih (Allium sativum); R3: R1 + 30 ppm ekstrak kulit bawang putih ; R4: R1 + 45 ppm ekstrak kulit bawang putih ; dan R5: R1 + 60 ppm ekstrak kulit bawang putih . Hasil penelitian menunjukkan bahwa perlakuan berpengaruh terhadap penurunan kecernaan bahan kering (KBK) dan kecernaan bahan organik (KBO), protozoa dan gas total, namun demikian terjadi peningkatan konsentrasi VFA total. Perlakuan memberikan respon linierÃÂàterhadapÃÂàKecernaan Bahan Kering, yaitu Y = 50.412 - 0,1651X ÃÂàdanÃÂàKBO, Y = -0,1768X + 50,319. Namun demikian pada ÃÂàVFAÃÂàÃÂàresponnya adalah kubik, dengan persamaan garis Y = 203,16 âÃÂà3,2646X + 0,2447X2 âÃÂà0,0033X3.ÃÂàDapat disimpulkan bahwa suplementasi ekstrak kulit bawang putih dan mineral organik dapat memperbaiki fermentasi rumen dengan level terbaik 25 ppm.ÃÂàKata kunci : ekstrak kulit bawang putih, mineral mikro, fermentasi rumenÃÂà|
