Penelitian yang bertujuan untuk mengkaji pengaruh suplementasi complete rumen modifier (CRM) dalam pakan domba terhadap bobot organ dalam telah dilaksanakan  pada tanggal 8 Agustus-11 Oktober 2021 di Eksperimental Farm Fakultas Peternakan Unsoed. Materi penelitian yang digunakan yaitu 18 ekor domba jantan ekor tipis umur 6-8 bulan, complete rumen modifier (CRM) tersusun dari tepung daun mengkudu 30%, tepung daun ketela rambat 30%, ampas teh kering 30%, Saccharomyces cerevisiae 3%, metionin 3%, dan mineral sulfur 4%, pakan jerami padi amoniasi dan konsentrat (onggok 49,5%, dedak padi 33%, bungkil kedelai 16,5 %, dan mineral 1%) dengan perbandingan 40:60 berdasarkan bahan kering pakan. Metode yang digunakan adalah metode eksperimental secara in vivo yang dirancang menggunakan Rancangan Acak Kelompok (RAK). Terdapat tiga perlakuan yang diuji yaitu P1 = jerami amoniasi 40% + konsentrat 60%, P2 = P1 + CRM 1%, dan P3 = P1 + CRM 2%. Setiap perlakuan diulang enam kali sehingga terdapat 18 unit percobaan. Variabel yang diamati dan diukur adalah bobot ginjal, bobot lemak ginjal, dan bobot hati domba. Hasil penelitian yang diperoleh persentase bobot ginjal P1 = 0,35±0,03, P2 = 0,32±0,03, P3 = 0,28±0,05, persentase bobot lemak ginjal P1 = 0,92±0,11, P2 = 1,07±0,17, P3 = 0,78±0,17, persentase bobot hati P1 = 2,00±0,27, P2 = 2,04±0,37, P3 = 1,88±0,16. Hasil analisis variansi membuktikan bahwa suplementasi CRM berpengaruh tidak nyata terhadap bobot ginjal, lemak ginjal, dan hati. Kesimpulan yang didapatkan adalah suplementasi CRM berpengaruh tidak nyata (P>0,05) terhadap bobot ginjal, lemak ginjal, dan hati. Penambahan CRM sebanyak 2% terbukti dapat menurunkan lemak pada ginjal.

This study aims to determine the effect of complete rumen modifier (CRM) supplementation on sheep feed on internal organ weight which was carried out from August 8 to October 11, 2021 at the Experimental Farm of the Faculty of Animal Science, Jenderal Sudirman University. The research materials used were 18 thin-tailed rams aged 6-8 months. The complete rumen modifier (CRM) is composed of 30% noni leaf flour, 30% sweet potato leaf flour, 30% dry tea dregs, 3% Saccharomyces cerevisiae, 3%  methionine, and 4% sulphur minerals. The ration consisted of ammoniated rice straw and concentrate with a ratio of 40:60 (Dry Matter Basis). The concentrate is composed of 49.5% tapioca by-product, 33% rice bran, 16.5% soybean meal, and 1% minerals. The study was conducted in vivo, using a Randomized Complete Block Design (RCBD).There were three treatments tested, namely P1 = 40% ammonia straw + 60% concentrate, P2 = P1 + 1% CRM, and P3 = P1 + 2% CRM. Each treatment was repeated six times so that there were 18 experimental units. The results obtained by the percentage of weight kidney P1 = 0.35±0.03 %, P2 = 0.32±0.03 %, and P3 = 0.28±0.05 %, the percentage of weight kidney fat P1 = 0.92±0.11 %, P2 = 1.07±0.17 %, and P3 = 0.78±0.17%,  the percentage weight liver P1 = 2.00±0.27%, P2 = 2.04±0.37 %, and P3 = 1.88±0.16 %. The results of the analysis of variance prove that CRM supplementation has no significant effect on the observed variables. The conclusion is that CRM supplementation to a level of 2% does not affect the percentage of kidney weight, kidney fat, and liver. The addition of 2% CRM has been shown to reduce fat in the kidneys.
