Pengaruh Imbangan Jerami Padi, Dedak Padi dan Onggok Terfermentasi terhadap Kecernaan dan Produk Fermentasi Rumen Secara In Vitro
ABSTRACT: Chemical and
physical treatments have been attempted to improve the utilization of agro
industrial wastes, but the result is not efficient and caused pollution.
Besides, biological treatments using the microbes have been used to improve the
nutritive value and utilization of agro industrial wastes. The current
experiment was conducted to find out the optimal ratio of fermented rice straw,
fermented rice bran and fermented tapioca waste. There were five kinds of ratio
of fermented rice straw, fermented rice bran and fermented tapioca waste,
namely: K1 (70% fermented rice straw + 15% fermented rice bran + fermented
tapioca waste), K2 (60% fermented rice straw + 20% fermented rice bran + 20%
fermented tapioca waste), K3 (50% fermented rice straw + 25% fermented rice
bran + 25% fermented tapioca waste), K4 (40% fermented rice straw + 30%
fermented rice bran + 30% fermented tapioca waste) and K5 (30% fermented rice
straw + 35% fermented rice bran + 35% fermented tapioca waste) An in vitro
technique, using completely Randomize Block Design was applied and each
treatment was repeated four times. Variables measured were Dry matter and
Organic matter digestibility and rumen fermentation products (volatile fatty
acid and N-NH3 concentration). The dry matter digestibility of K1, K2, K3, k4
and K5 was 29.39, 31.27, 32.33, 33.71 and 34.82%, respectively. The organic
matter digestibility of K1, K2, K3, K4 and 5 was 30.82, 31.27, 32.73, 34.94,
and 34.92, respectively. Volatile fatty acid concentrations of K1, K2, K3, K4
and K5 were 95.19, 91.77, 87.21, 104.31, 106.59 mM/l, respectively. N-NH3
concentrations of K1, K2, K3, K4 and K5 were 0.97, 0.93, 0.93, 1.00, 1.04 mM/l,
respectively. Significant difference (P<0.01) was only found in dry matter
digestibility among treatments, while others variables were not significantly
different among treatments. It was indicated that the optimal ratio was K4.
