PENGARUH TARAF PROTEIN DAN LISIN RANSUM TERHADAP PERFORMANS PRODUKSI AYAM KAMPUNG (Effect of Dietary Protein and Lysine Level on the Production Performance of Native Chicken)

Abstract

ABSTRAK

         Penelitian ini bertujuan untuk mengetahui dan mengkaji pemberian taraf protein dan lisin ransum yang sesuai terhadap performans ayam kampung. Parameter yang diukur adalah konsumsi ransum, pertambahan bobot badan, konversi ransum, presentase karkas, dan meat bone ratio. Penelitian menggunakan rancangan acak lengkap pola faktorial 2 x 3 dengan taraf protein sebagai faktor pertama dan taraf lisin sebagai faktor kedua. Setiap perlakuan memiliki 4 ulangan dengan 10 ekor ayam pada tiap unit percobaan. Perlakuan yang diterapkan adalah P1L1 (protein 17% + penambahan lisin 0,6% dari ransum), P1L2 (protein 17% + penambahan lisin 0,7% dari ransum), P1L3 (protein 17% + penambahan lisin 0,8% dari ransum), P2L1 (protein 14% + penambahan lisin 0,6% dari ransum), P2L2 (protein 14% + penambahan lisin 0,7% dari ransum), P2L3 (protein 14% + penambahan lisin 0,8% dari ransum). Perlakuan dimulai pada umur 1 hari hingga umur 12 minggu. Data dianalisis dengan uji F untuk mengetahui pengaruh perlakuan, dilanjutkan dengan uji jarak berganda Duncan pada taraf probabilitas 5% jika ada pengaruh signifikan dari perlakuan. Hasil penelitian menunjukkan tidak adanya pengaruh interaksi antara protein dan lisin ransum terhadap konsumsi ransum, pertambahan bobot badan, konversi ransum, presentase karkas, dan meat bone ratio. Berdasarkan hasil penelitian di atas, dapat disimpulkan bahwa penambahan lisin sintesis dalam ransum tidak dapat memberikan pengaruh yang berbeda dalam performans ayam kampung

ABSTRACT

            This research aimed to examine level of dietary protein and lysine which is optimum for native chicken performance. Parameters measured were feed consumption, body weight gain, feed conversion, carcass percentage, and meat bone ratio. The research used completely randomized design in 2 x 3 factorial pattern with dietary protein level as the first factor and lysine level as the second factor. Each treatment had 4 replications with 10 heads per trial unit. Treatments applied were P1L1 (protein level 17% + lysine addition 0.6% of diet), P1L2 (protein level 17% + lysine addition 0.7% of diet), P1L3 (protein level 17% + lysine addition 0.8% of diet), P2L1 (protein level 14% + lysine addition 0.6% of diet), P2L2 (protein level 14% + lysine addition 0.7% of diet), P2L3 (protein level 14% + lysine addition 0.7% of diet). The treatment was started  to be offered from 1-day-old and completed when the chicken were 12-week-old. The data was analyzed using F test to determine the effect of treatment, continued with Duncan's multiple range test at 5% probability level if any significant effect was found. The results showed no effect of the interaction between dietary protein and lysine on feed consumption, body weight gain, feed conversion, carcass percentage, and meat bone ratio. Based on the results, it was concluded that lysine addition was not give significant effect on native chicken performance.
