Cassapro in broiler ration : interaction with rice bran

Inglés. A three by three factorial experimental design (cassapro levels 0.5 and 10 percent x rice bran levels 0, 21 and 42 percent) was employed to study the effect of cassapro and rice bran and their interaction on boiler performance. All rations were formulated to be isonutrients. Each ration was fed to 40 three days old chicks, divided into 4 cages (10 birds/cage). Feed and water were given ad libitum during the 4 weeks trial. Feeding cassapro significantly (P0.05) improved body weight gain, with no significant effect on feed conversion ratio (FCR). Rice bran significantly (P0.001) reduced body weight gain and caused poorer FCR (P0.01). There was a significant interaction effect of cassapro and rice bran on body weight gain (P0.001). It is concluded that cassapro contained some factors, which are most likely digestive enzymes, which enchance digestibility of rice bran

desconocido. Satu percobaan dengan rancangan faktorial 3 x 3 (kadar cassapro 0,5 dan 1- persen x kadar dedak padi 0,21 dan 42 persen) dilakukan untuk mempelajari pengaruh cassapro dan dedak padi, serta interaksinya terhadp penampilan ayam pedaging. Semua ransum percobaan disusun dengan kandungan nutrien yang sama. Setiap ransum diberikan pada 40 ekor anak ayam berumur 3 hari, yang dibagi dalam 4 kandang (10 ekor/kandang). Ransum dan air diberikan secara bebas selama 4 minggu masa percobaan. Pemakaian cassapro dan ransum secara secara nyata (P0,05) meningkatkan pertambahan bobot badan, tetapi tidak mempunyai pengaruh yang nyata terhadap nisbah konversi pakan (FCR). Kadar dedak padi dalam ransum secara sangat nyata menurunkan pertambahan bobot (P0,01) maupun terhadap FCR (P0,001). Disamping bahwa cassapro mengandung unsur-unsur yang diperkirakan berbagai enzim pencernaan, yang dapat meningkatkan kecernaan dedak padi
