Abstract

The aims of  research is to assess and evaluate the application of a combination double step-down ( DSD ) diet and citric acid ( CA ) in improving the efficiency of broiler business . Research arranged in a completely randomized design ( CRD ) . A total of 168 broilers strains MB 202, 7 days old with average body weight of 186.23 ± 0.68 g were divided into 7 treatments and 4 replication     ( @ 6 broiler ). Treatments were : T0 ( control diet without a step-down and the CA) , T1 ( DSD diet without the CA ) , T2 ( DSD diet + 0.8 % CA of lime) , T3 ( DSD diet + 0.4 % CA synthetic ) , T4 ( DSD diet + 0.8 % of CA synthetic ) , T5 ( DSD diet + 1.2 % of CA synthetic ) and T6 ( DSD diet + 1.6 % of CA synthetic ) . The parameters measured in the present research were carcass weight , feed costs and income over feed cost ( IOFC ). ). The data were subjected to analysis of variance by F test followed Duncan test ( P < 0.05 ) and orthogonal polynomials ( PO ) to determine the optimal level of the CA. The results showed that the carcass weight did not differ ( P > 0.05 ) due to treatment . The treatment combination of DSD and the CA synthetic diet from 0.4% to 1.2 % ( T3 - T5 ) significantly ( P < 0.05 ) reduced diet costs and increase IOFC compared to control ( T0 ) . Based on the calculation of PO , the CA determined the optimal level of 0.96 % . Research conclusion that the application of a combination of double step-down diet and 0.8-1.2 % citric acid can be used as an alternative to increased efficiency in broiler production .

Abstract

Penelitian bertujuan untuk mengkaji dan mengevaluasi penerapan kombinasi pakan double step down (DSD) dan asam sitrat (AS) dalam meningkatkan efisiensi usaha peternakan broiler. Penelitian disusun dalam rancangan acak lengkap (RAL). Sebanyak 168 ekor broiler strain MB 202 umur 7 hari dengan bobot badan rata-rata 186,23±0,68 g dibagi dalam 7 perlakuan dan 4 ulangan (@ 6 ekor broiler). Perlakuan sebagai berikut: T0 (pakan kontrol tanpa step down dan AS), T1 (pakan DSD tanpa AS), T2 (pakan DSD + 0,8% AS jeruk nipis), T3 (pakan DSD + 0,4% AS sintetik), T4 (pakan DSD + 0,8% AS sintetik), T5 (pakan DSD + 1,2% AS sintetik) dan T6 (pakan DSD + 1,6% AS sintetik). Parameter yang diamati meliputi bobot karkas, biaya pakan serta income over diet cost (IOFC). Data dianalisis dengan uji F dilanjutkan uji Duncan (P<0,05) dan polinomial ortogonal (PO) untuk menentukan level optimal AS. Hasil penelitian menunjukkan bahwa bobot karkas tidak berbeda (P>0,05) akibat perlakuan. Perlakuan kombinasi pakan DSD dan AS sintetik 0,4-1,2% (T3-T5) nyata (P<0,05) menurunkan biaya pakan dan meningkatkan IOFC dibanding kontrol (T0). Berdasarkan perhitungan PO, dapat ditentukan level optimal AS sebesar 0,96%. Kesimpulan penelitian bahwa penerapan kombinasi pakan double step down dan asam sitrat 0,8-1,2% dapat digunakan sebagai alternatif peningkatan efisiensi produksi pada broiler. Kata kunci: pakan step down, asam sitrat, efisiensi produksi, broiler
