Rasio Efisiensi Protein dan Ukuran Linear Tubuh Babi Grower yang diberi Ransum Mengandung Kulit Pisang (musa Paradisiaca) Terfermentasi EM-4

Tujuan penelitian ini adalah untuk menentukan rasio efisiensi protein dan pertambahan ukuran linear tubuh babi yang mengkonsumsi ransum mengandung kulit pisang terfermentasi  EM-4. Materi yang digunakan adalah 12 ekor ternak babi peranakan landrace x duroc fase grower yang berumur 3–4 bulan, kisaran bobot badan awal 30–50 kg dan rataan 38,29 kg (KV=35,65%). Rancangan Acak Kelompok (RAK) digunakan dalam penelitian ini, yang memiliki 12 satuan percobaan dan empat perlakuan dengan tiga ulangan. Perlakuan tersebut adalah P0: ransum tanpa  kulit pisang terfermentasi EM-4; P1: ransum mengandung 10% kulit pisang terfermentasi EM-4; P2: ransum mengandung 15% kulit pisang terfermentasi EM-4; dan P3: ransum mengandung 20% kulit pisang terfermentasi EM-4.Variabel yang diteliti adalah rasio efisiensi protein dan pertambahan ukuran linear tubuh.  Perlakuan tidak berpengaruh nyata, menurut analisis statistik (P>0,05). rasio efisiensi protein dan pertambahan ukuran linear tubuh. Disimpulkan bahwa kulit pisang terfermentasi EM-4 sampai 20% memberikan pengaruh yang sama terhadap rasio efisiensi protein dan ukuran linear tubuh ternak babi grower.

The material used was 12 landrace x duroc crossbreed pigs in the grower phase aged 3–4 months, initial body weight range of 30–50 kg and an average of 38.29 kg (CV=35,65%). A Randomized Block Design (RBD) was used in this study which consisted of 4 treatments with three replications so that there were 12 experimental units. The treatments were P0: ration without fermented banana peel EM-4; P1 : ration contains 10% EM-4 fermented banana peel; P2: ration contains 15% EM-4 fermented banana peel; and P3: the ration contains 20% EM-4 fermented banana peel. The variables studied were the ratio of protein efficiency and linear body size increase. The results of statistical analysis showed that the treatment had no significant effect (P>0.05) on the protein efficiency ratio and the increase in body linear size. It was concluded that EM-4 fermented banana peels up to 20% gave the same effect on protein efficiency ratio and body linear size in grower pigs.   Keywords: pigs, banana peel,  body linear , protein efficiency ratio
