Judul: Total Produksi  Gas  dan  Degradasi  Berbagai Hijauan Tropis pada Media Rumen Domba Yang Diberi Pakan  Mengandung Saponin dan Tanin
Abstrak: The degradation of tropical browse plants in different fermented media rumen fluid had been determined in this experiment. The fermented media was collected from sheep which was obtained feed containing saponin and mix between saponin and tannin. The experimental design for in vitro was Factorial Randomized Block Design 9x3x2 with 3 replications. The first factor was nine kinds of tropical browse plant. The second factor was rumen fluid from sheep which fed with mixed grass (MG) (B1) , MG + saponin (B2) and MG + saponin + tannin (B3) and the third factor was with and without polyethylene glycol (PEG). The experimental design for in sacco was Factorial Randomized Block Design 9x3 with 2 replications. The first and second factors were similar to in vitro experiment. Variables observed were in vitro gas production, in vitro and in sacco dry matter degradation. The data were analyzed by Analysis of Variance, and differences among treatments were examined by Duncan Multiple Range Test. Results showed that difference of rumen fluid had no significant effect on in vitro gas production. In vitro gas production of Pennisetum purpureum and Artocarpus heterophyllus were significantly higher than other tropical browse plants. Rumen fluid containing saponin (P<0.05) significantly increased in sacco dry matter degradation, but there was no significant effect of all treatments on in vitro dry matter degradation. In sacco dry matter degradation of A. heterophyllus was significantly higher than other tropical browse plants but on in vitro, dry matter degradation of A. heterophyllus was similar to P. purpureum. Addition of PEG significantly increased in vitro gas production on B1 and B3, but decreased on B2. Addition of PEG had no effect on in vitro dry matter degradability of nine tropical browse plants.

Judul: Kinetika Produksi Gas dan Kecernaan in Vitro Pakan dengan Penambahan Mineral Organik Hasil Inokulasi dengan Saccharomyces cerevisiae dan Suplementasi Hijauan Bertanin
Abstrak: This research was aimed to observe the effect of organic micromineral, tanniniferous forage and its combination supplementation to gas production and in vitro digestibility.This research used king grass (Pennisetum hybrid) as control, leaves of neem (Azaditachta indica) as tanniniferous forage and monensin as antibiotic. A completely randomized design was applied to this research by using 7 treatments with 3 replications. Variables observed were physical quality of fermented feed, in vitro digestibility, number of protozoa, production of ammonia (NH3), concentration of methane (CH4), production of VFA, and gas production. The treatments were: P (P. hybrid), PO (P. hybrid + organic mineral 3%), POA (P. hybrid + organic mineral 3% + A. indica 2%), PM (P. hybrid + inorganic mineral 3%), PMA (P. hybrid + inorganic mineral 3% + A. indica 2%), PA (P. hybrid + A. indica 2%), PMO (P. hybrid + monensin 40 ppm). Results showed that inorganic mineral supplementation (PM) decreased digestibility of dry matter, i.e. from 63.95% to 32.14% (P<0.001). Organic mineral supplementation (PO) and inorganic mineral + A. indica (PMA) increased butyric acid production from 17.93 mM to 28.09 and 25.89 (P<0.01), respectively. Organic mineral supplementation + A. indica (POA) decreased total gas production from 45.37 to 41.55 ml (P<0.01). It can be concluded that organic mineral supplementation only affected butyric acid production and decreased total gas production when added with tanniniferous forage.
