Abstract

This study investigated the effect of phloroglucinol (1,3,5-trihydroxybenzene) supplementation alone on methane production, rumen fermentation profiles, and microbial population structure of mixed in vitro cultures. Treatments included a control group containing a substrate with no supplement, and substrates supplemented with 2, 4, 6, 8, or 10 mmol/L of phloroglucinol. The results revealed that phloroglucinol was able to decrease methane production in a dose-dependent manner. The highest decrease was observed with 8 and 10 mmol/L supplementations. The relative quantity of methanogen was not affected by phloroglucinol, whereas genus Coprococcus was increased with increasing concentrations of phloroglucinol (p<0.05). Total gas production, dry matter digestibility (DMD), and NH3-N were significantly lowered by phloroglucinol (p<0.001). Total short-chain fatty acid (SCFA) concentration was not affected by phloroglucinol. Acetate proportion increased with the addition of phloroglucinol at the expense of propionate (p<0.001). This might indicate the redirection of [H] from methane to acetate, and might be related to methane inhibition.. Our study concluded that supplementation of phloroglucinol alone could decrease methane production by inhibiting nutrient digestibility in the rumen and by possible redirection of rumen fermentation to acetate production. Genus Coprococcus could be an important actor for phloroglucinol metabolism in the rumen.

Abstract

Abstract Large amounts of polyunsaturated fatty acids undergo transformation processes in the rumen through microbial biohydrogenation to form fatty acids with higher saturation degree. The respective process explains the high content of saturated fatty acids in products of ruminants and the potential risk of consumers’ health by consuming such products. Various nutritional approaches have been attempted to modulate biohydrogenation process in order to obtain healthier fatty acid profile from consumers’ perspective. The present paper is aimed to review the influence of dietary tannin, a naturally produced plant secondary compound, on the pattern of polyunsaturated fatty acids biohydrogenation occurring in the rumen. The effect of tannin on some key fatty acids involved in biohydrogenation process is presented together with the underlying mechanisms, particularly from up-to-date research results. Accordingly, different form of tannin as well as different level of the application are also discussed. Key words: Tannin, biohydrogenation, fatty acid, ruminant

Abstract

This experiment was aimed to evaluate chemical composition, in vitro rumen fermentation, digestibility and methane emissions of some insects, i.e. Jamaican field cricket (JFC), mealworm (MW) and black soldier fly larvae age 1 and 2 weeks (BSF1 and BSF2). Insect samples were oven-dried at 60oC for 24 h, and ground to pass a 1 mm sieve. The ground samples were used subsequently for chemical composition determination and in vitro rumen fermentation test. Incubation was carried out in a water bath maintained at 39 ºC for 48 h in three replicates. Results revealed that all insect meals contained high crude protein, i.e. above 40% DM. Proportions of neutral detergent insoluble CP (NDICP) and neutral detergent insoluble CP (ADICP) were high in the insect meals than that of soybean meal (SBM), and these were particularly very high in BSF2. All insect meals had lower IVDMD and IVOMD than that of SBM (P<0.05). All insect meals had lower methane emissions as compared to SBM at 12, 24 and 48 h (P<0.05). It can be concluded that insect meals are potential protein supplements and have low methane emissions in vitro. However, their digestibility is rather low and may limit their utilization.

Abstract

This research was aimed at studying the in vitro ruminal biohydrogenation (BH) of C18 fatty acids (FA) in mixtures of Indigofera zollingeriana and Brachiaria decumbens. Four combinations of experimental rations of I. zollingeriana : B. decumbens were tested i.e., IZ 1 (45%:45%), IZ 2 (60%:30%), IZ 3 (75%:15%), and IZ 4 (90%:0%). The remaining 10% in in each ration was rice bran. The experimental design was based on a completely randomized design with five replicates. Results revealed that there was a statistically significant difference (P<0.01) in the composition of C18 unsaturated FA (UFA) and saturated FA (SFA) for each in vitro incubation period of 1, 2, 4, 8 and 24 h. The highest accumulation of C18 UFA at 24 h was observed in the incubation of IZ 4 (19.87%). The BH of C18:3, C18:2, and C18:1 showed no differences (P>0.05). Composition of C18:0 after incubation showed a significant difference (P<0.01) with the lowest composition was observed in IZ 2 (22%). In conclusion, combination of I. zollingeriana and B. decumbens at different ratio has minor inhibition effect on BH of C18 UFA.

Abstract

The objective of this study was to apply urea treatment of rice straw at elevated temperature and pressure (121oC; 1.4 atm) and at short treatment period (30 or 60 min) in comparison to conventional urea treatment (4 weeks incubation). Rice straw was subjected to the following treatments: RS1: untreated rice straw (control), RS2: RS1+1% urea (no incubation), RS3:RS1+1% urea (4 weeks incubation), RS4: RS2+autoclave 30 min, RS5: RS3+autoclave 30 min, RS6: RS2+autoclave 60 min, RS7: RS3+autoclave 60 min. The samples were analyzed for fiber contents and incubated in vitro. Data were analyzed using analysis of variance and Duncan’s post-hoc test. Results showed that urea treatments (RS3-RS7) did not change NDF and ADF contents of rice straw in comparison to control. Urea treatment in autoclave for 30 min (RS4) increased rice straw IVDMD and IVOMD by 23.3% and 25.6% as compared to control, respectively (P<0.05). Extension of the incubation period to 60 min (RS6) did not improve further the IVDMD and IVOMD. Treatments did not change pH values and NH3 concentrations. Urea treatment (RS3-RS7) increased total VFA concentration in comparison to control (P<0.05). It was concluded that urea treatment using autoclave for 30 min may replace conventional urea treatment to improve nutritional value of rice straw.

Abstract

Dairy cows often do not receive adequate nutrient supply during their lactation period. This condition caneven be worse if the environmental temperature is not in comfortable range which may occur especially intropical regions. The present research was aimed to simulate the effect of supplementary feeding on nutrientbalance of lactating dairy cow at contrasting temperature regimes using Cornell Net Carbohydrate andProtein System (CNCPS) model. Treatments consisted of feeds (R1: Pennisetum purpureum, R2: P.purpureum + concentrate (60:40), R3: P. purpureum + Gliricidia sepium + Leucaena leucocephala(60:20:20), R4: P. purpureum + concentrate + G. sepium + L. leucocephala (60:20:10:10)) and environmentaltemperatures (T1: 20 oC, T2: 30 oC). The dairy cow inputs in CNCPS were Holstein breed, body weight of500 kg, feed intake of 15 kg (dry matter basis) per day and produced milk 15 kg/day. Based on the CNCPSmodel, there were negative balances of metabolisable energy (ME) and metabolisable protein (MP) if alactating dairy cow fed only by P. purpureum. The ME balance was worse at higher temperature, while theMP balance was remain unchanged. Addition of concentrate mixture (R2) fulfilled the ME and MPrequirements as well as other nutrients. Addition of leguminous tree leaves (R3 and R4) improved thenutritional status of the lactating cow model compared to R1, but did not better than R2. It was concludedthat supplementary feeding is necessary for improving the nutrient balance of lactating dairy cow, especiallywhen the cow is maintained under uncomfortable environmental temperature.

Abstract

Rumen microbes breakdown feed to produce volatile fatty acids (VFA), carbon dioxide, ammoniaand methane (CH4). Metabolic hydrogen in the form of reduced protons is used during CH4 formation aswell as during VFA synthesis. Therefore, VFA concentration in the rumen may stoichiometrically berelated to CH4 emission. The aim of this study was to evaluate methane emission between experimentaland model estimates. Two stoichiometrical models for predicting CH4 from VFA were assessed, i.e.Moss et al. (2000) and Hegarty and Nolan (2007) models. The data sets were obtained from a publishedliterature. Samples used were leaves from 27 tropical plant species. Prediction error was conducted bycomputing root mean square prediction error (RMSPE). Results showed that estimation model of Mosset al. (2000) had lower RMSPE value, i.e. 8.01%, than that of Hegarty and Nolan (2007) model, i.e.10.73%. Variation of methane emission, i.e. the low or high methane can be estimated by VFAcomposition with a sufficient accuracy. Adjusment by considering H2 recovery lowered the biassignificantly. It can be concluded that Moss model had better accuracy in predicting CH4 emission fromVFA composition than that of Hegarty and Nolan model.

Abstract

This experiment was aimed to observe rumen fermentation kinetics of alternative supplements, i.e.Moringa oleifera and Peltiphyllum peltatum leaves added to maize silage diet as compared to aconventional supplement (barley-soya). A total of six treatments were investigated in the present study,which consisted of: maize silage (A), M. oleifera (B), P. peltatum (C), maize silage + concentrate (56:44,w/w; D), maize silage + M. oleifera (56:44, w/w; E), and maize silage + concentrate + P. peltatum(47:37:16, w/w/w; F). The feeds were incubated in vitro in three replicates (completely randomized)using the Reading Pressure Technique system. Approximately 800 mg of the feeds were mixed by 75 mlof buffered rumen liquor. The incubation was carried out up to 12 h in bottles and gas pressure wasrecorded and released in regular intervals. Repeated sampling was conducted for analysis offermentation products at 1, 6 and 12 h of incubation period. The results showed that the nutritionalquality of Moringa and its fermentation pattern was comparable to that of barley-soya concentrate. PlainMoringa incubation resulted the highest production of iso-SCFA and soluble protein concentrationamong all treatments after 12 h incubation (P<0.05). Incubation of sole Peltiphyllum peltatum highlyhampered the fermentation rate. Production of iso-SCFA both for plain Peltiphyllum and its mixturewere comparatively low. Supplementation of Peltiphyllum increased significantly soluble proteinconcentration during 12 h incubation (P<0.05). Peltiphyllum also had a very low C2+C4/C3 ratiocompared to other treatments. It could be concluded that Moringa oleifera is a potential alternativesupplement to replace either partially or completely concentrate as a conventional supplement, andPeltiphyllum peltatum supplementation could reduce excessive protein degradation and fermentation ofthe concentrate in the rumen.

Abstract

The aim of the present study was to conduct univariate, bivariate and multivariate (principalcomponent analysis, PCA) approaches in the screening of tannin-containing plants from variouscollection sites for their CH4 mitigating properties. Plant samples were obtained from various collectionsites in different countries, i.e. Indonesia (n = 27 species), Mongolia (n = 14), Switzerland (n = 16) andGermany (n = 3). The plants were incubated in vitro with buffered-rumen fluid at 39oC for 24 h. Totalgas production was recorded as an indicator of feed quality and emission of CH4 was measured. Resultsshowed that, based on bivariate screening, generally, plants possessed low CH4 production had lowquality or low total gas production except Rhus typhina, i.e. 43 ml/200 mg DM. The loading plot of PCAshowed that all phenolic fractions were in the opposite direction with CH4 and total gas production.Plants clustered together in reverse direction to that of CH4 were Bergenia crassifolia root and leaf,Swietenia mahagoni, Clidemia hirta, Peltiphyllum peltatum, Acacia villosa and R. typhina. It wasconluded that, for tannin-containing plants, screenings based on univariate, bivariate and multivariateapproaches in relation to ruminal CH4 emission led to similar results.

Abstract

This experiment was aimed to investigate the effect of combining tannin and saponin extracts onruminal methane emission of diets with different proportion of forage to concentrate in the in vitrofermentation. The experiment was conducted in a factorial block design. The first factor was theproportion of forage:concentate in diets (70:30 and 30:70) and the second was addition of tannin andsaponin extracts (control, tannins, saponins, tannins + saponins) in the dose of 2 mg/ml. Variablesobserved were gas production kinetics, methane production, dry matter digestibility (DMD), organicmatter digestibility (OMD) and ammonia concentration. Results revealed that addition of tannins,saponins and their combination generally lowered total gas and methane production during 24 and 48 hof incubation period in both types of diets (P<0.05), but combination of tannins and saponins comparedwith their separated forms did not show any significant differences. The addition of tannins, saponinsand their combination reduced DMD, OMD and ammonia significantly (P<0.05). It can be concludedthat the addition of tannin, saponin and their combination at a dose of 2 mg/ml could reduce methaneemission but followed by a decline in the DMD, OMD and ammonia.
