Karakteristik In Vitro Pakan Mengandung Ampas Sagu Aren (Arenga pinnata) yang Difermentasi Jamur Tiram Putih (Pleurotus ostreatus).

Abstract

Penelitian ini bertujuan mengevaluasi penggunaan konsentrat berbasis ampas sagu aren fermentasi sebagai pengganti dedak padi terhadap fermentabilitas rumen, kecernaan, dan total populasi mikroba secara in vitro. Penelitian ini terdiri atas 4 perlakuan dan 4 ulangan. Perlakuan terdiri atas ASAF0= Konsentrat dengan 0% Ampas Sagu Aren Fermentasi; ASAF10 = Konsentrat dengan 10% Ampas Sagu Aren Fermentasi; ASAF15 = Konsentrat dengan 15% Ampas Sagu Aren Fermentasi; ASAF20 = Konsentrat dengan 20% Ampas Sagu Aren Fermentasi. Parameter yang diuji adalah pH, konsentrasi amonia (NH3), total VFA, Kecernaan Bahan Kering, Kecernaan Bahan Organik, total populasi bakteri, total populasi protozoa, dan total produksi gas metana. Data dianalisis dengan menggunakan Analysis of Variance (ANOVA) dan perlakuan yang berbeda nyata akan diuji lanjut dengan Uji Duncan menggunakan software SPSS 23. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P

This study aimed to evaluate the use of fermented sago pith-based concentrate as a substitute for rice bran on rumen fermentability, digestibility, and total microbial population in vitro. The study consisted of 4 treatments with 4 replications. The treatments were ASAF0 = Concentrate with 0% Fermented Sago Pith; ASAF10 = Concentrate with 10% Fermented Sago Pith; ASAF15 = Concentrate with 15% Fermented Sago Pith; ASAF20 = Concentrate with 20% Fermented Sago Pith. The parameters tested were pH, ammonia concentration (NH3), total VFA, Dry Matter Digestibility, Organic Matter Digestibility, total bacterial population, total protozoal population, and total methane gas production. Data were analyzed using Analysis of Variance (ANOVA), and treatments that differed significantly were further tested with Duncan's Test using SPSS 23 software. The results showed that the treatments had no significant effect (P>0.05) on pH, total VFA, Dry Matter Digestibility, Organic Matter Digestibility, total bacterial population, and methane gas production. However, the treatments significantly increased (P<0.05) NH3 concentration and protozoa population. The conclusion of this study is that concentrate with fermented Sago Pith up to 20% usage level can replace rice bran, as indicated by no effect on rumen fermentability, digestibility, and total rumen microbial population.
