Evaluation of several tropical tree leaves for methane production potential, degradability and rumen fermentation in vitro

Effect of complete feed block with tree leaves rich in hydrolysable and condensed tannins on nutrient utilization, rumen fermentation and growth performance of lambs

“…Pal et al, (2015) also reported higher in vitro ruminal OM degradability and microbial biomass production in A. nilotica . Explanation for higher digestibility of fibre components in T2 could be the degradation and utilization of HT as an energy source in the rumen.…”

“…Tree leaves of A. nilotica and Z. nummularia have potential effect on methane mitigation and in vitro degradability (Pal, Patra, Sahoo, & Kumawat, 2015). The two plant species, A. nilotica and Z. nummularia, are abundantly available in arid and semi-arid regions and are also rich source of hydrolysable (HT) and condensed tannins (CT) (Pal et al, 2015). The two plant species, A. nilotica and Z. nummularia, are abundantly available in arid and semi-arid regions and are also rich source of hydrolysable (HT) and condensed tannins (CT) (Pal et al, 2015).…”

“…Tanniniferous leaves yield positive effect on rumen fermentation, digestibility and animal performance (Dey, Dutta, Sharma, & Pattanaik, 2008). Tree leaves of A. nilotica and Z. nummularia have potential effect on methane mitigation and in vitro degradability (Pal, Patra, Sahoo, & Kumawat, 2015). There is limited information on types of tannin polyphenols and their effects on feed intake, ruminal attributes, nutrient utilization and post-weaning growth performance of lambs.…”

Differences in the nutrient concentrations, in vitro methanogenic potential and other fermentative traits of tropical grasses and legumes for beef production systems in northern Australia

“…We identified differences in nutritive values, fermentability and methanogenic potential amongst selected forages, with some plants producing twice as much CH 4 as others. The nutritive profiles and fermentability in other tropical plants has been reported previously, but this is the first attempt to conduct a systematic and controlled study and examine temporal variations in these parameters.…”

“…Several potential CH 4 abatement strategies for ruminants grazing tropical forages have been considered, including variability in plant nutritive value and fermentability features, especially amount of CH 4 produced when digested by rumen microbes (‘methanogenic potential’) . However, such attributes, in particular methanogenic potential, of legumes and grasses in northern Australia are unknown.…”
