“…This results suggests that addition of whole methanolic extracts of LL had increased nutrient degradability without affecting ruminal ecosystem. In contrast, Patra et al (2006) reported that, addition of different solvent extracts suppressed the IVDMD and IVOMD of feed, attributed to the detrimental effects of some secondary metabolite present in the solvent extracts.…”

“…Orthogonal polynomial contrasts were used to find out the linear (L), Quadratic (Q) and Cubic (C) response (Significant (*** P<0.001; ** P<0.01; * P<0.05)). Similarly, Patra et al (2006) reported that addition of methanol extract of T. chebula 95% reduced methane production with the lower dose of 0.25 ml/30 ml incubation medium and the authors attributs presence of tannins and phenolic acids might be responsible for decrease in methane production. Furthermore, Oskoueian et al (2013) suggested that pure flavonoids compounds (myricetin, kaempferol, quercetin and catechin) was responsible for CH4 reduction.…”

“…Furthermore, Kim et al (2013) found that, pine needles and gingko leaf extracts appears to have antimethanogenic properties by decreasing protozoa species. On the other hand, Patra et al (2006) reported that, Populus deltoides leaves inhibited methanogenesis process without adversely affecting other rumen characteristics. Similarly, reduction of CH4 production (P<0.05) in plants such as Leucaena (88%) and Acacia (89%) in which were subjected into in vitro gas production technique .…”

“…Several studies have been confirmed to decrease CH4 emissions by in vitro and in vivo experiment using tanniferous plant and extracts . Patra et al (2006) reported that addition of methanol extract of T. chebula plant reduced methane emission. Populus deltoides leaf extracts were subjected into in vitro experiment showed that decrease in methane production with highest dosage (PATRA et al, 2008).…”

“…Livestock production is a significant source of greenhouses gas emissions and there is a constant endeavor for animal nutritionists to improve the animal performance in terms of manipulation of rumen microbial ecosystem, enhancing fibrous feed digestibility, methane reduction and excretion of nitrogen by ruminants (PATRA et al, 2006).…”

Research is never the effort of a single individual and it is a team work and many have put their effort in several ways to bring this thesis to completion. and degraded neutral detergent fiber (DNDF), especially LL, which had most influence on these parameters compared to other tannin containing plants. LL had positive response on antimethanogenic effects; its nutrient degradability was higher than that of other tannin containing plants. The second study (Expt. 2) was set to evaluate the effect of different organic extracts from the whole plant methanolic extract (MHE) of LL on in vitro gas production and to characterize the chemical constituents by using gas chromatography coupled with mass spectroscopy (GC-MS). Major abundant compounds present at the relative percentages of MHE were found to be stigmasterol trimethyl ester (TMS), neophytadiene, palmitic acid TMS, α-Linolenic acid TMS and 2, 3, 5, 6-tetra methyl anisylbenzene. The effects of additions of different extracts in terms of nutrient degradability (TDOM and DNDF) were increased by all extracts. This study explained that the methanolic hexane extract and methanolic chloroform extract was effective against methanogenic activity. The objective of the third study (Expt. 3) was to study the effect of LL plant leaves on rumen fermentation, apparent nutrient digestibility, nitrogen balance and methane production in Santa Ines sheep. The animals were divided in three groups in which they were fed with (i) 88% Tifton 85-hay (Cynodon spp.) and 12% soyabean meal (Control group, n=4); (ii) 28% Tifton 85-hay (Cynodon spp.) and 72% LL plus 20 ml solution containing 10g/day/animal of PEG (With PEG group -WPEG, n=6); (iii) 28% Tifton 85-hay (Cynodon spp.) and 72% LL plus 20 ml of distilled water (without PEG group-WOPEG, n=6). Nutrient intake (dry matter, organic matter, acid detergent fiber, lignin and crude protein) were higher in WPEG and WOPEG compared to the control group, except neutral detergent fiber intake. Apparent digestibilities and nitrogen metabolism had non-significant effects between the treatments. However, CH4 emissions were significantly lower in WPEG and WOPEG than the control. Furthermore, expressions of microbial populations of methanogens in WPEG had lower tendency than that of WOPEG and control. The most salient findings of this study were that, 72% LL plant leaves using in small ruminants diets increased animal productivity, we can get more benefits in terms of replacing the source of protein in the...
