Abstract

Silage is the feedstuff resulted from the preservation of forages through lactic acid fermentation. The aim of this study was to evaluate nutritive value, fermentation characteristics and nutrients digestibility of rice crop residue based silage ensiled with epiphytic lactic acid bacteria (LAB). The mixture of rice crop residue (RC), soybean curd residue (SC) and cassava waste (CW) in a 90: 5: 5 (on dry matter basis) ratio was used as silage material.  Three treatments silage were (A) RC + SC + CW as a control; (B) RC + SC + CW + LAB inoculums from rice crop residue; (C) RC + SC + CW + LAB inoculums from king grass.  Silage materials were packed into plastic silo (1.5 kg capacity) and stored for 30 days. The results showed that crude protein content in B and C silage was higher than that of silage A, but NDF content in silages B and C was lower than that of silage A.  Lactic acid concentration was higher (P < 0.01) in silage C compared to silage B and A, thus pH value of silage C was lower (P < 0.01) than silage B and A. Silage C had the highest Fleigh point than that of other silages. Dry matter and organic matter digestibilities were higher in silages B and C (P < 0.01) than that of control silage. It was concluded that the addition of LAB inoculums from king grass to rice crop residue based silage resulted a better fermentation quality compared to LAB inoculums from rice crop residue.

Abstract

This experiment was conducted to evaluate the effect of extract of plants containing tannin on invitro CH4 production, fermentation characteristics and nutrient degradability. Six of plant leaves i.e.Gliricidia sepium, Acacia mangium, Leucaena leucocephala, Desmodium intortum, Camellia sinensis,Calliandra calothyrsus and seed of Areca catechu were extracted by using water. Experimentaltreatments consisted of P. purpureophoides (300±5 mg) incubated alone or added with 1.2 mL of plantextracts. The in vitro neutral detergent fibre (NDF) degradability was determined using the first stagetechnique of Tilley and Terry. The results showed that total tannin concentration of plant extract rangedfrom 34 to 95 g/kg DM, and was lowest in D. intortum and highest in A. mangium. Methane productionwas significantly (P<0.001) lower with addition of A. mangium, L. leucocephala, A. catechu, C. sinensisand C. calothyrsus extracts compared to control. Total tannin had a close relationship with CH4production (r=-0.79). There was strong correlation between CH4 production and NDF degradability(r=0.61). It was concluded that water extracts of A. mangium, L. leucocephala, A. catechu, C. sinensisand C. calothyrsus have potential to be used as rumen manipulator in order to reduce CH4 production inruminants.
