“…The above results suggested that condensed tannins from rambutan peel have a weaker inhibition effect on the fermentation rate. These results were in agreement with Anantasook and Wanapat (2012), who reported that supplementation of rain tree pod meal containing condensed tannins and saponins at 4, 8 and 12 mg/0.2 g DM had no effect on cumulative gas production. In contrast, Paengkoum et al (2015) reported that cumulative gas production was decreased by supplementation of mangosteen peel condensed tannins at 2-6% DM.…”

The current study was aimed to determine the effect of rambutan peel powder (RPP) supplementation on in vitro gas production, rumen fermentation characteristics and methane production. The experimental design was a completely randomized design and the dietary treatments were different levels of RPP supplementation at 0, 4, 8, 12, 16 and 20 mg/0.5 g DM. Under this investigation, RPP supplementation did not affect gas production kinetics and in vitro digestibility (p > .05). The concentration of NH 3 -N decreased linearly with the increasing levels of RPP supplementation (p < .05). Propionate was increased (p < .05) when supplemented with RPP at 16 mg, while acetate and butyrate remained the same. On the other hand, supplementation of RPP decreased methane production (p < .05). This study indicated that RPP at 16 mg could be used as a rumen enhancer for manipulating rumen fermentation.

“…The average NH 3 -N concentration of all treatments was 14.21 mL dL -1 and was within the optimum ruminal NH 3 -N range of 12 and 17 mL dL -1 for optimal fermentation and rumen microbial growth (Anantasook and Wanapat, 2012;Lunsin et al, 2012). As expected, MPES and MPES + ES supplements increased the dietary levels of carbohydrate and nitrogen, resulting in an increase in NH 3 -N concentration levels and decrease in CO 2 production due to the microbial mass formation.…”

“…In the current study, the pH ranged from 6.94 to 7.19. These values are considered optimal for the normal rumen fermentation, for the synthesis of volatile fatty acid, and microbial protein (Wanapat and Pimpa, 1999;Anantasook et al, 2012), and are also within the range of 6.2 to 7.2, considered appropriate for optimal microbial activity (Van Soest, 1994), as expected for diets based on forage.…”

-The objective of this study was to evaluate the effects of mineral and protein-energy (MPES), exogenous fibrolytic enzyme supplements (ES), combination of MPES + ES, and straw without supplement (WS) on digestibility, fermentation kinetic parameters, cumulative gas production, methane, CO 2 production, and volatile fatty acid concentration of rice straw of low and high nutritional value, estimated by in vitro techniques. The experimental design was randomized and factorial 2 × 4: two straws (low and high nutritional value) incubated with four supplements (MPES, ES, MPES + ES, and WS) and their interactions. Four experimental periods were used, totaling four replications per treatment over time. Data were analyzed by PROC MIXED of SAS. The in vitro dry matter and organic matter digestibilities of the rice straw with high nutritional value was improved by MPES, while the combination of MPES + ES supplements inhibited the digestibility of this straw. Dietary carbohydrate and nitrogen increased through MPES and MPES + ES supplements resulted in an increase in NH 3 -N concentration and a decrease in CO 2 production due to the microbial mass formation. However, this increase was not enough to improve organic matter degradability parameters, cummulative gas production, gas production kinetics, and acetate:propionate ratio and reduce methane emissions. The straw with high nutritional value showed greater content of nitrogen fraction a, effective degradability, cummulative gas production, and methane and CO 2 productions comparing with low-nutritional value straw. The use of MPES and MPES + ES supplements can be used as strategy to mitigate CO 2 in ruminant production systems that use rice straw.Key Words: digestibility, digestion kinetics, fatty acid, gas production, methane Revista Brasileira de Zootecnia

The objective of this study was to determine the effect of rain tree pod meal with palm oil supplementation on feed intake, digestibility, microbial protein synthesis and microbial populations in dairy cows. Four, multiparous early-lactation Holstein-Friesian crossbred (75%) lactating dairy cows with an initial body weight (BW) of 405±40 kg and 36±8 DIM were randomly assigned to receive dietary treatments according to a 4×4 Latin square design. The four dietary treatments were un-supplementation (control), supplementation with rain tree pod meal (RPM) at 60 g/kg, supplementation with palm oil (PO) at 20 g/kg, and supplementation with RPM at 60 g/kg and PO at 20 g/kg (RPO), of total dry matter intake. The cows were offered concentrates, at a ratio of concentrate to milk production of 1:2, and chopped 30 g/kg of urea treated rice straw was fed ad libitum. The RPM contained condensed tannins and crude saponins at 88 and 141 g/kg of DM, respectively. It was found that supplementation with RPM and/or PO to dairy cows diets did not show negative effects on feed intake and ruminal pH and BUN at any times of sampling (p>0.05). However, RPM supplementation resulted in lower crude protein digestibility, NH3-N concentration and number of proteolytic bacteria. It resulted in greater allantoin absorption and microbial crude protein (p<0.05). In addition, dairy cows showed a higher efficiency of microbial N supply (EMNS) in both RPM and RPO treatments. Moreover, NDF digestibility and cellulolytic bacteria numbers were highest in RPO supplementation (p<0.05) while, supplementation with RPM and/or PO decreased the protozoa population in dairy cows. Based on this study, supplementation with RPM and/or PO in diets could improve fiber digestibility, microbial protein synthesis in terms of quantity and efficiency and microbial populations in dairy cows.
