Pengaruh Penambahan Probiotik Rhizopus Oryzae Terhadap Total Mikroba Usus Halus Dan Seka Ayam Kampung Periode Grower (the Effect of Probiotic Rhizopus Oryzae Administrationon the Total Number of Microbes in the Small Intestine and Caeca of Kampoeng Chicke

摘要

The purpose of this study was to investigate the effect of probiotic Rhizopus oryzaeadministration on the total number of microbes in the smallintestine and caeca of kampoengchickens during the growerperiod. The study was conducted on 11 August to 11 October 2014 in the poultry farm at the Faculty of Animal and Agricultural Sciences, Diponegoro University.The materials used in this study were 100 Day Old Chick (DOC) (unsexed) with initial body weight of 37.90 ± 1,36 g.The experiment was set asCompletely Randomized Design (CRD).The treatments consisted of T0 (control), T1 (0.1% addition of probiotic Rhizopus oryzae to the diet) and T2 (0.2% addition of probiotic Rhizopus oryzae to the diet).The results showed that addition of probioticRhizopus oryzae in the diet did not affect (P>0.05) the total number of microbesin the small intestine and caeca ofchicken during the grower period, but affected (P<0.05) the daily gain of chicken within 0-9 weeks.The highest daily gain was observed in T1 which was not different (P>0.05) from T2 but different (P<0.05) from T0.The conclusion of this study was the administration of Rhizopus oryzae with a dose of 0.1 % and 0.2 % in the chicken dietdid not increase the total number of microbes in the small intestine and caeca of kampong chickensduring the grower period, but the additionof Rhizopus oryzae could increase the daily gain at 0-9 weeks of age,at which the highest impact was observed when Rhizopus oryzae was added at 0.1 %.
