The present study was undertaken to observe the effect of supplementing Aegle marmelos leaves on in vitro rumen fermentation and methane production of different diets containing varied proportion of roughage (R) to concentrate (C). Aegle marmelos (Bael) leaves was supplemented at 4 levels (0, 5, 10 and 15%) to three diets having roughage (R) and concentrate (C) (wheat straw and concentrate mixture) in the ratio 70:30, 50:50 and 30:70. Inclusion of Aegle leaves at different levels showed significant rise in total gas (mL/g DM) among different diets. Similarly, Aegle marmelos leaves at the rate of 15% improved (P>0.05) the IVTDMD and IVTOMD (%) of the experimental diets. Among the VFA’s acetate concentration (mM) was significantly enhanced at 15% of Aegle marmelos supplementation. No significant effect was observed in the values of CH4 (%, mL/24h and mL/100mg DDM) and NH3-N (mg/dL) on supplementation of Aegle leaves if any of the diets. Therefore, it can be concluded from the present findings that supplementation of Aegle marmelos leaves enhances the digestibility hence it can be used to improve the nutritive value of diets.

In Vitro Rumen Fermentation

Nutritional strategies can be employed to mitigate greenhouse emissions from ruminants. This article investigates the effects of polyphenols extracted from the involucres of Castanea mollissima Blume (PICB) on in vitro rumen fermentation. Three healthy Angus bulls (350 ± 50 kg), with permanent rumen fistula, were used as the donors of rumen fluids. A basic diet was supplemented with five doses of PICB (0%–0.5% dry matter (DM)), replicated thrice for each dose. Volatile fatty acids (VFAs), ammonia nitrogen concentration (NH3-N), and methane (CH4) yield were measured after 24 h of in vitro fermentation, and gas production was monitored for 96 h. The trial was carried out over three runs. The results showed that the addition of PICB significantly reduced NH3-N (p < 0.05) compared to control. The 0.1%–0.4% PICB significantly decreased acetic acid content (p < 0.05). Addition of 0.2% and 0.3% PICB significantly increased the propionic acid content (p < 0.05) and reduced the acetic acid/propionic acid ratio, CH4 content, and yield (p < 0.05). A highly significant quadratic response was shown, with increasing PICB levels for all the parameters abovementioned (p < 0.01). The increases in PICB concentration resulted in a highly significant linear and quadratic response by 96-h dynamic fermentation parameters (p < 0.01). Our results indicate that 0.2% PICB had the best effect on in-vitro rumen fermentation efficiency and reduced greenhouse gas production.
