摘要：Jatropha curcas meal (JCM) contains high crude protein (58%-60%), but it can not be used properly because of anti-nutritional contents known as curcin and phorbolesther. These components interferes protein metabolism and body protein synthesis. This study was conducted to evaluate the effect of feeding fermented JCM using Rhizopus oligosporus on broilers' performances. Ninety six of day old chicks of Ross strain broiler (initial body weight 45.6±1.7 g) were used and reared for five weeks. The treatments were: R0 (diet without JCM), R1 (diet contained 3% fermented JCM), R2 (diet contained 6% fermented JCM) and R3 (diet contained 9% fermented JCM). A completely randomize design with 4 treatments and 4 replications was assigned in this experiment. The data were analyzed using analysis of variance (ANOVA). The results indicated that feeding fermented JCM at the level of 3% to 9% in starter and grower-finisher broilers highly significant reduced (PR. oligosporus indicated no effective detoxification process in relation to the improvement of broiler performances.
其他摘要：Bungkil biji jarak pagar (BBJP) mengandung protein tinggi (58%-60%), namun ketersediaan protein tersebut sangat rendah, disebabkan beberapa zat antinutrisi yang terkandung dalam BBJP, diantaranya curcin dan phorbolesther. Zat antinutrisi tersebut mengganggu metabolisme dan sintesis protein dalam tubuh. Tujuan penelitian ini adalah untuk mengevaluasi pengaruh pemberian BBJP hasil fermentasi menggunakan Rhizopus oligosporus pada ayam broiler. Penelitian menggunakan anak ayam umur satu hari (d.o.c) strain Ross sebanyak 96 ekor (bobot badan awal rata-rata 45,6±1,7 g/ekor) dan dipelihara selama 5 minggu. Perlakuan ransum yang diberikan adalah: R0 (ransum tanpa BBJP), R1 (ransum mengandung 3% BBJP fermentasi), R2 (ransum mengandung 6% BBJP fermentasi) dan R3 (ransum mengandung 9% BBJP fermentasi). Data dianalisis menggunakan sidik ragam (ANOVA). Hasil penelitian menunjukkan bahwa pemberian BBJP fermentasi sebanyak 3%–9% dalam ransum ayam broiler periode starter dan grower-finisher sangat nyata menurunkan (P<0,01) konsumsi ransum, bobot badan akhir, dan pertambahan bobot badan. Pemberian BBJP fermentasi sebanyak 9% sangat nyata meningkatkan (P<0,01) angka mortalitas ayam broiler pada periode starter maupun grower-finisher. Fermentasi BBJP menggunakan R. oligosporus belum efektif dalam menurunkan antinutrisi yang tercermin dari tidak adanya perbaikan performa ayam broiler.
