Replacement of chemical compounds by dietary sources as rumen enhancers have been of great interest and concern by researchers. Four, rumen-fistulated swamp buffalo bulls with average liveweight of 365 ± 15.0 kg were randomly assigned to treatments, to investigate the impact of banana flower powder (BAFLOP) as a rumen modifier on pH, rumen fermentation, nutrient digestibility, microbial protein synthesis and volatile fatty acids. All buffaloes were allotted according to a 4 × 4 Latin square design. Dietary supplementation treatments were as follows: 2 g concentrate/kg bodyweight (BW; T1), 15 g concentrate/kg BW (T2), 15 g concentrate/kg BW plus BAFLOP 300 g/head.day (T3) and 15 g concentrate/kg BW plus BAFLOP 600 g/head.day (T4). Untreated rice straw was fed ad libitum. The findings showed that total feed intake was increased in buffaloes fed a diet supplemented with concentrate at 2 g/kg BW, while rice straw intake was reduced. Nutrient digestibility was increased by BAFLOP supplementation at both levels (T3 and T4; P < 0.05). Ruminal pH dropped (5.9) in buffaloes fed with concentrate at 15 g/kg BW, while buffaloes with BAFLOP supplementation could maintain ruminal pH when fed with high-concentrate diet. Ruminal ammonia-nitrogen increased in the buffaloes fed concentrate at 15 g/kg BW, especially with BAFLOP supplementation. Feeding high-concentrate diet increased the concentrations of ruminal total volatile fatty acids and propionic acid (C3), while the concentration of acetic acid and the acetic acid:C3 ratio and methane production were subsequently reduced (P < 0.05). In addition, efficiency of microbial protein synthesis was increased by the BAFLOP feeding (P < 0.05). In the present study, using BAFLOP as a dietary rumen enhancer at 300–600 g/head.day resulted in an increased rumen pH, C3 concentration, nutrient digestibility and microbial protein synthesis, while mitigating ruminal methane production. Higher nutrient digestibility and lower ruminal methane production, more dietary energy and production efficiency are expected.

Improving of rice straw quality and its effect on ability nutrient digestibility and rumen metabolism products of buffalo in-vitro with feces as inoculum source ABSTRACT.  This study was aimed to determine the effect of feeding  ammoniated rice straw plus concentrate on buffalo nutrient digestibility and rumen fermentation products by in vitro. The Research was carried out by using  experimental method, designed according to completely  randomized design (CRD). The source of inoculum was obtain from different feces of three  buffalos kept in  Datar Village of Purwokerto region fed  rice straw, rice straw plus concentrate and rice straw ammoniated plus concentrate with dry matter ratio of 80 : 20. The treatments tested consisted of three treatments, namely R0 =  control feed using rice straw; R1 = the use of rice straw plus concentrate with a ratio of  (DM basis) 80:20; R2 = the use of ammoniated rice straw plus concentrate with a ratio of (DM basis) 80:20. The treatments were repeated 7 times, so there were 21 experimental units. The Variables measured included total VFA, Ratio A/P, N-NH3, Microbial Protein Synthesis (MPS),   Dry Matter and Organic Matter Digestibility. The result of this study showed that the treatment had an effect significant (P0.05) on the concentration of VFA, Ratio A/P,  N-NH3,  Microbial Protein Synthesis (MPS), and Dry Matter and Organic Matter Digestibility. The HSD test showed that the highest production of  VFA,Ratio A/P, N-NH3, Microbial Protein Synthesis (MPS), Dry Matter and Organic Matter Digestibility were achieved at R2 followed by R1 and R0 respectively. The conclusion is that the ammoniated rice straw supplemented with concentrate can be recommended to be fed to buffalo

Abstract This study investigated the effects of engineered biocarbon on nutrient digestibility, rumen fermentation, total gas and methane (CH4) emissions, and microbial protein synthesis in a rumen simulation technique (RUSITEC) fed a barley silage-based TMR. The basal diet consisted of 60% barley silage, 27% barley grain, 10% canola meal and 3% minerals. Three pine-based biocarbon products CP016, CP024 and CP028. were added at 2% of substrate DM. Biocarbons differed in bulk density, surface area, pore volume, pH, but had similar chemical compositions. Treatments were assigned to sixteen vessels (n = 4/treatment) in two RUSITEC apparatuses in a randomized block design. The experiment period was 17 d, with a 10-d adaptation and 7-d sample collection period. Data were analyzed using the PROC MIXED in SAS, with treatment (T), day (D) and TxD interactions as fixed effects and RUSITEC apparatus and fermenters as random effects. Compared to the control, biocarbon did not affect total gas (P = 0.98), the amount of CH4 produced per unit of DM incubated (P = 0.48) or per unit of DM digested (P = 0.27). Biocarbon treatments averaged 6.5 g of CH4 /g DM incubated and 9.06 g CH4 /g DM digested as compared to 7.1 g of CH4 /g DM incubated and 10.46 g CH4 / g DM digested in the control, respectively. Biocarbon CP024 had the greatest numerical reduction, followed by CP028 then CP016 in all CH4 associated parameters. Biocarbon addition did not affect the disappearance of DM (P = 0.63), OM (P = 0.34), CP (P = 0.48), NDF (P = 0.12), or VFA (P = 0.65) and ammonia N levels (P = 0.99) and protozoal counts (P = 0.72). The amount of bacterial nitrogen (mg/d) associated with feed particles increased (P < 0.003), suggesting that biocarbon may have enhanced colonization. In conclusion, engineered biocarbon did not reduce CH4 emissions in the RUSITEC.

This study investigated the effects of three pine-based biochar products on nutrient disappearance, total gas and methane (CH4) production, rumen fermentation, microbial protein synthesis, and rumen microbiota in a rumen simulation technique (RUSITEC) fed a barley-silage-based total mixed ration (TMR). Treatments consisted of 10 g TMR supplemented with no biochar (control) and three different biochars (CP016, CP024, and CP028) included at 20 g·kg−1 DM. Treatments were assigned to 16 fermenters (n = 4 per treatment) in two RUSITEC units in a randomized block design for a 17 d experimental period. Data were analyzed using MIXED procedure in SAS, with treatment and day of sampling as fixed effects and RUSITEC unit and fermenters as random effects. Biochar did not affect nutrient disappearance (P > 0.05), nor total gas or CH4, irrespective of unit of expression. The volatile fatty acid, NH3-N, total protozoa, and microbial protein synthesis were not affected by biochar inclusion (P > 0.05). Alpha and beta diversity and rumen microbiota families were not affected by biochar inclusion (P > 0.05). In conclusion, biochar did not reduce CH4 emissions nor affect nutrient disappearance, rumen fermentation, microbial protein synthesis, or rumen microbiota in the RUSITEC.
