“…In the past few decades, feed additives such as antibiotics were used in ruminant production for optimization of the rumen fermentation pattern and to improve feed intake and efficiency ( Abdl-Rahman, 2010 ; Patra, 2011 ). However, presently most of these supplements are not used routinely because of toxicity problems in the host animals and microbial adaptation.…”

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.

“…The optimal value of NGR in the rumen is about 3.5, and a value lower than 3.5 indicates more efficient utilization of SCFA for gluconeogenesis (Abdl-Rahman, 2010). In the current study, TB supplementation had no effect on the fermentation pattern in ewes indicated by the fairly constant NGR, which is consistent with previous research (Kowalski et al, 2015).…”

In vivo and in vitro trials were conducted to assess the effects of tributyrin (TB) supplementation on short-chain fatty acid (SFCA) concentrations, fibrolytic enzyme activity, nutrient digestibility and methanogenesis in adult sheep. Nine 12-month-old ruminally cannulated Small Tail ewes (initial body weight 55 ± 5.0 kg) without pregnancy were used for the in vitro trial. In vitro substrate made to offer TB at 0, 2, 4, 6 and 8 g/kg on a dry matter (DM) basis was incubated by ruminal microbes for 72 h at 39°C. Forty-five adult Small Tail ewes used for the in vivo trial were randomly assigned to five treatments with nine animals each for an 18-d period according to body weight (55 ± 5.0 kg). Total mixed ration fed to ewes was also used to offer TB at 0, 2, 4, 6 and 8 g/kg on a DM basis. The in vitro trial showed that TB supplementation linearly increased apparent digestibility of DM, crude protein, neutral detergent fibre and acid detergent fibre, and enhanced gas production and methane emissions. The in vivo trial showed that TB supplementation decreased DM intake, but enhanced ruminal fermentation efficiency. Both in vitro and in vivo trials showed that TB supplementation enhanced total SFCA concentrations and carboxymethyl cellulase activity. The results indicate that TB supplementation might exert advantage effects on rumen microbial metabolism, despite having an enhancing effect on methanogenesis.

“…A influência de adsorventes de natureza argilosa como a montmorilonita sobre indicadores de fermentação ruminal foi investigada em outros estudos [1,2,[17][18][19]. A redução na quantidade de metano (CH4) em 24 h, observada no presente estudo, possivelmente foi decorrente da menor atividade das bactérias metanogênicas.…”

“…A MMT induziu a diminuição da viabilidade de protozoários responsáveis em abrigar bactérias metanogênicas, prejudicando a relação de simbiose dessas bactérias com a população de protozoários [18]. A redução significativa da quantidade de amônia (NH3) pode ser relacionada à capacidade de armazenamento de NH3 pela MMT ou pela redução da atividade proteolítica dos protozoários [1]. A adição de 0,75% de MMT na dieta de ovinos, alimentados com alto teor de grãos, aumentou a quantidade de AGCC e o pH ruminal foi estabilizado mais próximo da neutralidade [19].…”

Background: The addition of adsorbents in foods has been the strategy used by nutritionists to reduce the toxic effects of mycotoxins in animals. Mycotoxins are found in a range of foods and commonly they present variations in the chemical structure therefore, it has been appropriate to include adsorbents from different sources in the diet of ruminants. However, few researches were conducted in order to better understand the interaction of adsorbents on ruminal fermentation. Our objective in this study was to investigate the possible effects of two adsorbent products on bovine ruminal fermentation. One consists of 65% of β-glucan (β-glu), originating cell wall of Saccharomyces cerevisiae and used at a concentration of 1% and natural sodium montmorillonite (MMT) at a concentration of 5%. Materials, Methods & Results:The effects of β-glu adsorbents (1%) and MMC (5%) in culture medium that simulated ruminal fermentation were evaluated. Bottles, with a capacity of 120 mL, were used to be filled with substrate such as maize and ryegrass hay ground, nutrient solution (medium of Menke), liquid extracted rumen fistulated bovine and the two adsorbents evaluated, totaling 50 mL. The experiment was conducted with three treatments, named after: control (Cont), β-glu and MMT. In the control treatment adsorbents were not added. Six replicates were used for each treatment and two trials were conducted. One of the tests aimed to determine the fermentation kinetics by means of the gas production after 72 h' incubation and quantifying the production of methane (CH4) at 48h. While another test aimed to quantify the production of short chain fatty acids (SCFA) -acetic, propionic and butyric acid -and the production of ammonia (NH3) in 24 h incubation. All assays were measured by gas chromatography. The highest total SCFA concentration was observed in β-glu treatment (67.71 mM) significantly superior to CONT (57.7 mM) treatment and MMT (53.28 mM), which was significantly lower than the β-glu treatment, but similar to CONT. The average representation (%) of acetic acid for the treatment MMT (62.9%) was significantly higher than the β-glu treatment (61.0%). The average proportions of propionic acid were similar between treatments, while the average representation (%) of butyric acid production was significantly higher for the β-glu treatment (13.1%) compared to CONT treatments (11.3%) and MMT (11.4%). The amount of NH3 was significantly reduced in MMT (9.6 mM) treatment compared to β-glu treatments (12.2 mM) and CONT (11.3 mM). In another test, the greater volume of gas (mL) was produced by β-glu treatment (103.4 mL), which was significantly greater than the treatments CONT (89.0 mL) and MMT (91.6 mL). The lag time, i.e. the time taken by the bacteria inoculum to develop lead-through in the substrate, in the MMT treatment took 6.2 h, slowing significantly compared to CONT treatments (4.8 h) and β Glu (4.33 h). The concentration of CH4 was significantly lower in MMT treatment (33.0%) compared to the CONT treatments (36.3%) and ...
