Abstract

Intisari Keseimbangan protein dapat menunjukkan apakah ternak dalam keadaan bertambah atau berkurang kadar protein di dalam tubuhnya. Penelitian ini bertujuan untuk mengetahui pemanfaatan protein pakan komplit berkadar protein dan energi yang berbeda dalam tubuh ternak domba. Domba lokal jantan sebanyak 24 ekor, umur 3-5 bulan dan bobot badan (88) awal 8,7-15,5 kg (CV := 15,01 %) dirancang dengan rancangan acak kelompok umum ke dalam 4 (empat) perlakuan pakan komplit, yaitu R1 == 14,48% protein kasar (PK) dan 50,46% total digestible nutrients (TON), R2 == 17,35% PK dan 52 ,61 % TON, R3 = 15,09% PK dan 58,60% TON dan R4 = 17,42% PK dan 57,46% TON. Pengelompokan domba berdasarkan BB awal. Data yang diperoleh dianalisis dengan analisis variansi dan apabila ada perbedaan dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan, bahwa jumlah protein tercerna berbeda nyata (P<0,05) diantara perlakuan pakan, yaitu 75,05, 99,60, 67,79, dan 84,07 g masingmasing untuk R1, R2, R3, dan R4, tetapi kecernaan proteinnya (55,36-61,26%) tidak berbeda nyata (P>0,05). Jumlah protein teretensi dan retensi protein tidak berbeda nyata (P>0,05), yaitu antara 36,56-57,93 g dan 26,67-42,64%. Konversi protein tercerna pada R3 (0,78) lebih rendah (P<0,05) daripada R1 (0,94), R2 (1,01), dan R4 (0,95), sedangkan konversi protein teretensi tidak berbeda nyata (P>0,05), yaitu 0,25-0,36. Kesimpulan hasil penelitian ini adalah pemanfaatan protein pakan komplit dengan kadar protein dan energi yang berbeda untuk penggemukan domba relatif sama. Kata Kunci: Keseimbangan Protein, Pakan Komplit, Protein-Energi Berbeda, Feedlot, Domba Lokal Jantan, PROTEIN UTILIZATION OF COMPLETE FEED WITH DIFFERENT PROTEIN AND ENERGY LEVELS TO MALE LOCAL SHEEP FATTENING ON FEEDLOT SYSTEM Abstract Protein balance showed that what the body protein content of animal was plus or minus. This research was conducted to know protein utilization of complete feed with different protein and energy levels to male local lamb on feedlot system. Twenty four males local lamb, aged around 3-5 months with body weight of 8.7-15.5 kg (CV = 15.01%) were set in a generalized randomized (complete) block design with 4 treatments: R1 (CP 14.48% and TON 50.46%), R2 (CP 17.35% and TON 52.61 %), R3 (CP 15.09% and TON 58.60%), and R4 (CP 17.42% and TON 57.46%). The ANOVA was used to analyze data and any differences among groups were further tested using Duncan Multiple Range Tests (DMRT). The result showed that the amount of digestible protein were significantly different (P<0.05), there are 75.05, 99.60, 67.79, and 84.07 g, respectively for R 1, R2, R3, dan R4, but digestible protein (55.36-61 .26%) was not Significantly different (P>0.05). The amount of retention protein was not significantly different (P>0.05), there are 36.56 -57.93 g or 26.67 -42.64%. Digestible protein conversion of R3 (0.78) was smaller (P<0.05) than R1 (0.94), R2 (1 .01), and R4 (0.95), while retention protein conversion was not significantly different (P>0.05), that is 0.25 -0.36. It was concluded that the use of complete feed with different protein and energy levels to sheep on feedlot system were same relatively.
