“…In contrast to CT, HT are thought to be degradable in the rumen (Makkar, 2003), suggesting that the effects of HT identified in vitro may disappear with time in vivo due to rumen degradation (Murdiati et al, 1992). Thus, animal studies are required to investigate whether tannins are able to reduce methane release over a longer period of several weeks (de Oliveira et al, 2007;Beauchemin et al, 2009;Jayanegara et al, 2011). The first objective of the present study was to examine the effect of long-term feeding of CHE and VAL extract on methane release in sheep.…”

The long-term effects of adding chestnut (CHE; Castanea sativa) and valonea (VAL; Quercus valonea) tannin-rich extracts to sheep feed were investigated. In Experiment 1, sheep (65 kg BW) were fed 842 g/day of a ryegrass-based hay. The control-treated animals (CON) received 464 g/day of concentrate, and tannin-treated animals received the same amount of concentrate additionally containing 20 g of the respective tannin-rich extract. Hay and concentrates were offered together in one meal. After the onset of treatment, methane release was measured in respiration chambers for 23.5-h intervals (nine times) in a 190-days period. Faeces and urine were collected three times (including once before the onset of the tannin treatment) to assess digestibility and urinary excretion of purine derivatives. Based on the results obtained from Experiment 1, a second experiment (Experiment 2) was initiated, in which the daily tannin dosage was almost doubled (from 0.9 (Experiment 1) to 1.7 g/kg BW 0.75 ). With the exception of the dosage and duration of the treatment (85 days), Experiment 2 followed the same design as Experiment 1, with the same measurements. In an attempt to compare in vitro and in vivo effects of tannin supplementation, the same substrates and tannin treatments were examined in the Hohenheim gas test. In vitro methane production was not significantly different between treatments. None of the tannin-rich extract doses induced a reduction in methane in the sheep experiments. On the 1st day of tannin feeding in both experiments, tannin inclusion tended to decrease methane release, but this trend disappeared by day 14 in both experiments. In balance period 3 of Experiment 1, lower dry matter and organic matter digestibility was noted for tannin treatments. The digestibility of CP, but not NDF or ADF, was reduced in both experiments. A significant shift in N excretion from urine to faeces was observed for both tannin-rich extracts in both experiments, particularly in Experiment 2. In balance period 2 of Experiment 2, an increased intake of metabolisable energy for VAL was observed. The urinary excretion of purine derivatives was not significantly different between treatments, indicating that microbial protein synthesis was equal for all treatments. Thus, we concluded that both tannin-rich extracts temporary affect processes in the rumen but did not alter methane release over a longer period.

“…These contradictory results could be due to the differences in the type of diet. In addition, factors such as dry matter intake (DMI) and F : C ratio could be crucial to the amount of methane -E-mail: zhuweiyun@njau.edu.cn 1788 produced in the rumen and/or interacts with fumarate supplementation (De Oliveira et al, 2007).Several studies have reported a positive effect of fumarate on the growth of different rumen microorganisms. Nisbet and Martin (1993) reported that 10 mM fumarate stimulated the growth of Selenomonas ruminantium in pure cultures, and Asanuma et al (1999) showed that 30 mM fumarate increased the growth of Fibrobacter succinogenes, S. ruminantium, Veillonella parvula, Selenomonas lactilytica and Wolinella succinogenes in pure cultures.…”

This study investigated the effects of disodium fumarate (DF) on methane emission, ruminal fermentation and microbial abundance in goats under different forage (F) : concentrate (C) ratios and fed according to maintenance requirements. Four ruminally fistulated, castrated male goats were used in a 4 × 4 Latin square design with a 2 × 2 factorial arrangement of treatments and the main factors being the F : C ratios (41 : 59 or 58 : 42) and DF supplementation (0 or 10 g/day). DF reduced methane production (P< 0.05) on average by 11.9%, irrespective of the F : C ratio. The concentrations of total volatile fatty acids, acetate and propionate were greater in the rumen of goats supplemented with DF (P< 0.05), whereas the abundance of methanogens was lower (P< 0.05). In high-forage diets, the abundance ofSelenomonas ruminantium, a fumarate-reducing bacterium, was greater in the rumen of goats supplemented with DF. The abundance of fungi, protozoa,Ruminococus flavefaciensandFibrobacter succinogeneswere not affected by the addition of DF. Variable F : C ratios affected the abundance of methanogens, fungi andR.flavefaciens(P< 0.05), but did not affect methane emission. The result implied that DF had a beneficial effect on thein vivorumen fermentation of the goats fed diets with different F : C ratios and that this effect were not a direct action on anaerobic fungi, protozoa and fibrolytic bacteria, the generally recognized fiber-degrading and hydrogen-producing microorganisms, but due to the stimulation of fumarate-reducing bacteria and the depression of methanogens.

“…Thus, better pasture management, supplementary feeding practices, substitution of forage for food containing less fibre, adequate sanitary control, integrated management of animal wastes and the genetic improvement of animals are techniques that may improve livestock productivity and reduce emissions linked to beef cattle production (Barioni et al, 2007;Boadi et al, 2004;Iqbal et al, 2008;Oliveira et al, 2007;Pedreira et al, 2004;Segnini et al, 2007;Wilkins and Hump, 2003).…”

a b s t r a c tThe carbon footprint (CF) of beef production is one of the most widely discussed environmental issues within the current agricultural community due to its association with climate change. Because of these relevant and serious concerns, the beef cattle industry is under increasing pressure to reduce production or implement technological changes with significant consequences in terms of beef marketing. The goals of this study were to evaluate the CF per 1 kg of live weight gain (LWG) at the farm gate for different beef production systems in the southern part of Brazil. Aberdeen Angus beef-bred cattle were assigned to one of seven categories: natural grass; improved natural grass; natural grass plus ryegrass; improved natural grass plus sorghum; cultivated ryegrass and sorghum; natural grass supplemented with protein mineralised salt; and natural grass supplemented with protein-energetic mineralised salt. Monte Carlo analysis was employed to analyse the effect of variations of dry matter intake digestibility (DMID), total digestible nutrients (TDN) and crude protein (CP) parameters in methane (CH 4 ) enteric, CH 4 manure, nitrous oxide (N 2 O) manure and N 2 O N-fertiliser. The method used was a comparative life cycle assessment (LCA) centred on the CF. The CF varied from 18.3 kg CO 2 equivalent/kg LWG for the ryegrass and sorghum pasture system to 42.6 kg CO 2 equivalent/kg LWG for the natural grass system, including the contributions of cows, calves and steers. Among all grassland-based cattle farms, production systems with DMID from 52 to 59% achieved the lowest CO 2 emissions and the highest feed conversion rate, thereby generating lower CH 4 and N 2 O emissions per production system. Because the feed intake and feed conversion rate are one of the most important production parameters in beef cattle production with an obvious risk of data uncertainty, accurate feed data, which include quantity and quality, are important in estimates of CF for LWG. The choice of adequate feeding strategies to mitigate greenhouse gas (GHG) emissions may result in better environmental advantages.
