MUSCLE FIBER DIAMETER AND FAT TISSUE SCORE IN QUAIL (Coturnix-coturnix japonica L) MEAT AS AFFECTED BY DIETARY TURMERIC (Curcuma longa) POWDER AND SWANGI FISH (Priacanthus tayenus) MEAL

Abstract

The objectives of this study were evaluate the dietary turmeric powder and swangi fish meal on size of muscle fiber diameter and fat tissue score of major pectorales and semimembranosus of quail meat. Research was conducted based on 2x3 of factorial completely randomized design, in which the first factor was 2 types of diet, i.e. RA : standard diet; RB : 85% standard diet + 15% swangi fish meal, and the second factor was 3 levels of period time of turmeric powder addition, i.e. P0 : without turmeric powder; P1 : turmeric powder 54 mg/quail/day was given since quail age 210 days old; P2 : turmeric powder 54 mg/quail/day was given since quail age 14 days old. Difference of means between treatment groups were analyzed by Duncan’s Multiple Range Test in 95% significance level. The results showed that combined treatment of tumeric powder with RA (P0 : 2.33 μm; P1 : 3.06 μm; P2 : 2.98 μm) and RB (P0 : 2.22 μm; P1 : 3.12 μm; P2 : 2.92 μm) increased (P<0.05) muscle fiber diameter on major pectorales significantly. Muscle fiber diameter on semimembranosus were increased (P<0.05) by combined treatment of tumeric powder with RA (P0 : 2.83 μm; P1 : 3.50 μm; P2 : 3.24 μm) and RB (P0 = 2.85 μm; P1 = 3.28 μm; P2 = 3.33 μm). In conclusion, combined treatment of RA (standard diet) and RB (diet with Swangi fish meal) increased (P<0.05) the size of muscle fiber diameter in major pectorales and semimembranosus Tujuan penelitian ini adalah untuk mengevaluasi pengaruh penggunaan tepung kunyit dan ikan swangi terhadap ukuran diameter serat otot dan jaringan lemak major pectorales dan semimembranosus pada daging puyuh. Penelitian menggunakan rancangan acak lengkap pola faktorial 2x3, yaitu faktor pertama adalah jenis ransum terdiri RA : ransum standar dan RB : 85% ransum standar + 15% tepung ikan swangi, dan faktor kedua adalah periode pemberian tepung kunyit terdiri dari 3 level yaitu P0 : tanpa diberi tepung kunyit; P1 : diberi tepung kunyit 54 mg/ekor/hari sejak berumur 210 hari; P2 : diberi tepung kunyit 54 mg/ekor/hari sejak berumur 14 hari. Perbedaan bermakna antar kelompok perlakuan dianalisis menggunakan uji Duncan's Multile Range Test pada taraf signifikasi 95%. Hasil penelitian menunjukkan bahwa combinasi perlakuan tepung kunyit dengan RA (P0 : 2,33 μm; P1 : 3,06 μm; P2 : 2,98 μm) maupun dengan RB (P0 : 2,22 μm; P1 : 3,12 μm; P2 : 2,92 μm) meningkatkan secara nyata (P<0.05) diameter serat otot pada major pectorales. Kombinasi tepung kunyit dengan RA dan dengan RB juga meningkatkan secara nyata (P<0.05) diameter serat otot pada semimembranosus. Kesimpulan penelitian ini adalah suplementasi tepung kunyit pada ransum RA dan RB meningkatkan secara nyata (P<0.05) ukuran dari diameter serat otot pada major pectorales dan semimembranosus.
