Abstract
Performance of broilers fed diets containing potassium diformate to replace flavomycinABSTRACT. The aim of this research was to study the effect of potassium-diformate (PD) on broiler performance. One hundred and twenty old chicks of Cobb strain were divided into fifteen groups and feed one of five treatments, namely: P1 (control diet), P2 (P1 + 0,5%PD), P3(P1 + 1%PD), P4 (P1 + 1,5%PD) and P5 (P1 + antibiotic). Data from Completely Randomized Design were analyzed by ANOVA and any significant among them were used contrast orthogonal test. Treatments did not impact on feed consumption, mortality and percentage of viscera, but the groups treated with 1 and 1.5% PD and flavomicyne antibiotic had significant improvement on body weight gain (P0.169) and feed efficiency (P0.05). It is concluded that addition of 1-1.5% potassium-diformate in the broiler’s diet could improve feed efficiency and replace flavomycine antibiotic as growth promotors without influencing the performance of viscera.

Summary
Materi DOC strain Cobb sebanyak 120 ekor dibeli dari perusahaan komersial. Pottasium-diformat (PD) yang digunakan dengan merk dagang FORMI® diperoleh dari PT BASF Biochemical Company serta antibiotik flavomycin yang diperoleh dari industri pakan di Bogor. Obat-obatan yang digunakan adalah vaksin NDI, NDII dan IBD yang dibeli dari toko obat hewan di Bogor. Metode Sebanyak 120 ekor DOC strainn Cobb dibagi secara acak ke dalam 15 kelompok. Setiap kelompok diberikan secara acak salah satu dari lima perlakuan ransum, yaitu : P1(ransum basal/kontrol), P2 (ransum basal+ 0,5%pottasium-diformat/PD), P3 (ransum basal+1,0%PD), P4 (ransum basal+1,5%PD), P3 (ransum basal+ 2ppm flavomycin). Data performan dari Rancangan Acak Lengkap (RAL) dianalisis ragam (ANOVA), sedangkan data organ dalam yang diperoleh ditransformasikan dalam arcsin X dan dianalisa menggunakan analisa ragam (ANOVA). Peubah yang diamati terdiri dari konsumsi ransum, pertambahan bobot badan, konversi ransum, bobot dan panjang organ dalam broiler
