Fermentasi biji karet (Hevea brasiliensis) menggunakan kapang yang berbeda terhadap organ limfoid dan hati ayam kampung

Abstract

This research was conducted to determine the effect of the addition of fermented rubber seed flour as a feed mixture on the internal organ weight of native chickens. This study used 90 native chickens. The treatments in this study were P0 (without treatment): P1 (Rhizopus oligosporus 5%) : P2 (Neurospora sitophila 5%) The parameters measured were the relative weight of the thymus organ, the relative weight of the spleen organ, the relative weight of the bursa of Fabrisius organ, and the relative weight liver organs. The experimental design in the study used RAL (Completely Randomized Design). The data obtained was analyzed using Analysis of Variance (ANOVA), if there was a significant difference (P<0.05) then it would be continued with the Duncan Multiple Range Test (DMRT) with 3 treatments and 5 replications. Based on the research results, the administration of rubber seed flour using Rhizopus oligosporus 5% and Neurospora sitophila 5% in feed rations had no significant effect (P>0.05) on the relative weight of the thymus organ, relative weight of the spleen organ, relative weight of the bursa of Fabricius, and relative weight of the liver. The conclusion of the study was that fermenting rubber seeds using Rhizopus oligosporus and Neurosphora sitophila at a dose of 5% in mixed feed did not cause a negative effect on the weight of lymphoid organs and chicken livers.
