Abstract


The aim of this work was to study the effect of various energy/protein ransum ratios on the performance of  108 male Muscovy ducks (Cairina moschata) of 3 weeks of age which were treated under different housing systems, i.e., cage and ranch. Research method employed a Completely Randomized Design of  Factorial Nested Patterns which were energy/protein ransum (E/P) ratio (B factor) at housing systems of cage and ranch (A factor). Each treatment consisted of three ducks at two replications each. Nine E/P ratio  (R) given were:  R1: 2400/13; R2: 2400/15; R3: 2400/17; R4: 2600/13; R5: 2600/15; R6: 2600/17; R7:2800/13; R8: 2800/15; and R9: 2800/17.  Feeding trial variable observed were: feed, energy and protein consumption, body weight gain, feed conversion ratio, carcass weight and "income over feed cost". Results indicated that (1) Housing Muscovy ducks in cage gave a better value of income over feed cost than that of ranch system (Rp. 5076.08 over Rp. 3978.79 per duck); (2)The best performance and income over feed cost value obtained from R4:2600/13 (= 17.33 kcal/g protein) of cage housing systems.

Penelitian untuk mengetahui pengaruh berbagai imbangan energi/protein terhadap 108 ekor  entog jantan berumur 3 minggu yang dipelihara pada kandang cage dan ranch telah dilakukan. Metode percobaan yang digunakan adalah Rancangan Acak Lengkap Pola Dua Faktor Tersarang, yaitu Imbangan E/P Ransum (faktor B) yang tersarang pada sistem kandang cage dan ranch (faktor A). Setiap perlakuan diulang 2 kali dan setiap ulangan terdiri atas 3 ekor anak entog. Sembilan macam ransum energi/protein (R) yang diberikan adalah: R1:2400/13; R2:2400/15; R3:2400/17; R4:2600/13; R5:2600/15; R6:2600/17; R7:2800/13; R8:2800/15; dan R9:2800/17.  Peubah yang diamati adalah konsumsi ransum, konsumsi energi, konsumsi protein, pertambahan bobot badan, konversi ransum, bobot karkas dan income over feed cost.  Hasil penelitian menunjukkan bahwa: (1) Pemeliharaan entog jantan pada kandang sistem cage (Rp. 5076,08/ekor) menghasilkan income over feed cost yang lebih tinggi dibandingkan pemeliharaan pada  kandang ranch (Rp. 3978,79/ekor). (2) Ransum dengan R4:2600/13 (= 17,33 kkal/g protein) menghasilkan performansi dan nilai income over feed cost terbaik pada kandang cage.
