PENGARUH PENGGUNAAN MINYAK ATSIRI DAUN CENGKEH TERHADAP KONSUMSI PROTEIN KASAR, ENERGI DAN RASIO EFESIENSI PENGGUNAAN PROTEIN PAKAN PADA AYAM RAS PETELUR JANTAN

ABSTRAK
Minyak atsiri daun cengkeh dapat dimanfaatkan sebagai antifungi dan antioksidan pada ternak unggas. Penelitian yang dilakukan bertujuan untuk mengetahui pengaruh penggunaan minyak atsiri daun cengkeh dalam pakan terhadap konsumsi protein, konsumsi energi dan rasio efesiensi protein pada ayam ras petelur jantan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dengan 6 ulangan. Perlakuan yang digunakan yaitu P1 = Pakan basal, P2 = Pakan basal + antibiotik tetracycline 0,05g/kg pakan, P3 = Pakan basal + minyak atsiri daun cengkeh 6,3g/kg pakan, P4 = Pakan basal + minyak atsiri daun cengkeh 12,6g/kg pakan, dan P5 = pakan basal + minyak atsiri daun cengkeh 18,9g/kg pakan. Data yang diperoleh di analisis ragam dan pengaruh perlakuan terhadap peubah yang diamati diuji dengan uji Beda Nyata Jujur (BNJ). Hasil analisis ragam menunjukan bahwa perlakuan berpengaruh sangat nyata (P<0,01) terhadap konsumsi protein, konsumsi energi dan rasio efesiensi protein. Penggunaan minyak atsiri daun cengkeh sebanyak 6,3g/kg dapat digunakan sebagai pakan tambahan dalam pakan ayam ras petelur jantan dan mempunyai hasil yang relatif sama dengan penggunaan antibiotik tetracycline 0,05g/kg pakan.

Kata Kunci: minyak atsiri daun cengkeh, ayam ras petelur jantan, konsumsi protein kasar, konsumsi energi, rasio efesiensi protein

ABSTRACT
Clove leaf essential oil can be used as antifungal and antioxidant in poultry. The research was conducted to determine the effect of using clove leaf essential oil in feed on protein consumption, energy consumption and protein efficiency ratio in laying hens. This study used a completely randomized design (CRD) with 5 treatments with 6 replications. The treatments used were P1 = basal feed, P2 = basal feed + tetracycline antibiotic 0.05g/kg feed, P3 = basal feed + clove leaf essential oil 6.3g/kg feed, P4 = basal feed + clove leaf essential oil 12, 6g/kg feed, and P5 = basal feed + clove leaf essential oil 18.9g/kg feed. The data obtained in the analysis of variance and the effect of treatment on the observed variables were tested with the Honest Significant Difference (BNJ) test. The results of the analysis of variance showed that the treatment had a very significant effect (P<0.01) on protein consumption, energy consumption and protein efficiency ratio. The use of clove leaf essential oil as much as 6.3g/kg can be used as additional feed in the feed of laying hens and has relatively the same results as the use of tetracycline antibiotics 0.05g/kg of feed.
