“…Reductions in gas production and DMD observed in the sainfoin cultures were consistent with results from other studies examining the impact of tannins (e.g., Frutos et al, 2004a;Rodríguez et al, 2011;Lobón et al, 2015) and have been attributed to their inhibition of bacterial attachment to feed particles, microbial growth and enzyme activity (McAllister et al, 1994;Smith et al, 2005). Nonetheless, it must be considered that the effects of tannins on ruminal fermentation, as well as on BH, are highly variable depending on their type, dosage rate, microbiota adaptation to their consumption, etc.…”

“…Nonetheless, it must be considered that the effects of tannins on ruminal fermentation, as well as on BH, are highly variable depending on their type, dosage rate, microbiota adaptation to their consumption, etc. (Tiemann et al, 2008;Doce et al, 2009;Rodríguez et al, 2011). Furthermore, inherent differences in the chemical composition of both forages, which was very similar but not identical, cannot be ignored and might also contribute to explain some subtle differences.…”

There is still controversy surrounding the ability of tannins to modulate the ruminal biohydrogenation (BH) of fatty acids (FA) and improve the lipid profile of milk or meat without conferring a negative response in the digestive utilization of the diet. Based on this, an in vitro trial using batch cultures of rumen microorganisms was performed to compare the effects of two legume hays with similar chemical composition but different tannin content, alfalfa and sainfoin (Onobrychis viciifolia), on the BH of dietary unsaturated FA and on the ruminal fermentation. The first incubation substrate, alfalfa, was practically free of tannins, while the second, sainfoin, contained 3.5% (expressed as tannic acid equivalents). Both hays were enriched with sunflower oil as a source of unsaturated FA. Most results of the lipid composition analysis (e.g., greater concentrations of 18:2n-6, cis-9 18:1 or total polyunsaturated FA in sainfoin incubations) showed the ability of this tannin-containing legume to inhibit the BH process. However, no significant differences were detected in the accumulation of cis-9 trans-11 conjugated linoleic acid, and variations in trans-11 18:1 and trans-11 cis-15 18:2 did not follow a regular pattern. Regarding the rumen fermentation, gas production, ammonia concentration and volatile FA production were lower in the incubations with sainfoin (‒17, ‒23 and ‒11%, respectively). Thus, although this legume was able to modify the ruminal BH, which might result in improvements in the meat or milk lipid profile, the present results were not as promising as expected or as obtained before with other nutritional strategies.

“…The inhibition of methanogenesis has long been considered from nutritional aspects, and more recently from the perspectives on greenhouse gas emissions. In the previous studies by Śliwiński et al (2002); Patra et al (2006); Patra et al (2010); Rodríguez et al (2011) who reported that CH4 production reduced by addition of plant extract containing tannin. In contrast, Beauchemin et al (2007) described that supplementing a forage-based diet with quebracho tannin extract failed to reduce CH4 production from growing cattle.…”

Penelitian ini dilaksanakan untuk mengevaluasi pengaruh perbedaan ekstrak tanaman yang mengandung tanin terhadap produksi CH4, karakteristik fermentasi dan degradasi nutrien secara in vitro. Enam jenis daun tanaman yaitu Gliricidia sepium, Acacia mangium, Leucaena leucocephala, Desmodium intortum, Camellia sinensis, Calliandra calothyrsus dan biji Areca catechu diekstraksi menggunakan pelarut air. Perlakuan percobaan terdiri atas P. purpureophoides (300±5 mg) diinkubasi tunggal atau ditambah 1,2 mL ekstrak tanaman. Degradasi NDF diukur menggunakan prosedur Tilley and Terry tahap pertama. Hasil penelitian menunjukkan bahwa konsentrasi tanin total pada ekstrak tanaman bervariasi antara 34-95 g/kg BK, terendah pada D. intortum dan tertinggi pada A. mangium. Produksi CH4 pada inkubasi 48 jam signifikan lebih rendah (P<0,001) dengan penambahan ekstrak A. mangium, L. leucocephala, A. catechu, C. sinensis dan C. calothyrsus dibandingkan kontrol. Tanin total mempunyai hubungan yang erat dengan produksi CH 4 (r=-0,79). Terdapat korelasi yang kuat antara produksi CH 4 dan konsentrasi NDF (r=0,61). Disimpulkan bahwa ekstrak tanaman A. mangium, L. leucocephala, A. catechu, C. sinensis dan C. calothyrsus menggunakan air berpotensi sebagai manipulator untuk menurunkan produksi CH 4 pada ternak ruminansia.

“…Reduction in digestibility of DM, OM and CP at levels of incorporation of 3 and 4% CT in the ration may suggest that at those concentrations there may have occurred some interference on the activity of fibrolytic bacteria and protozoa in the rumen (Galindo et al., ; Bhatta et al., ; Rodríguez et al., ) since protozoa are responsible for about 50% of the fibrolytic activity in the rumen (Coleman, ), even when it is not ruled out the possibility that CT may have been present in concentrations enough to form complexes with proteins and carbohydrates which reduced rumen degradation of ration components (Soltan et al., ; Tedeschi et al., ).…”

The aim of the experiment was to assess the effect of condensed tannins (CT) on feed intake, dry matter digestibility, nitrogen balance, supply of microbial protein to the small intestine and energy utilization in cattle fed a basal ration of Pennisetum purpureum grass. Five heifers (Bos taurus × Bos indicus) with an average live weight of 295 ± 19 kg were allotted to five treatments consisting of increasing levels of CT (0, 1, 2, 3 and 4% CT/kg DM) in a 5 × 5 Latin square design. Dry matter intake (DMI) was similar (p> 0.05) between treatments containing 0, 1, 2 and 3% of CT/kg DM and it was reduced (p < 0.05) to 4% CT (5.71 kg DM/day) with respect to that observed with 0% CT (6.65 kg DM/day). Nitrogen balance, purine derivatives excretion in urine, microbial protein synthesis and efficiency of synthesis of microbial nitrogen in the rumen were not affected (p ≥ 0.05) by the increase in the levels of condensed tannins in the ration. Energy loss as CH was on average 2.7% of the gross energy consumed daily. Metabolizable energy intake was 49.06 MJ/day in cattle fed low-quality tropical grass with a DMI of 6.27 kg/day. It is concluded that concentrations of CT between 2 and 3% of DM of ration reduced energy loss as CH by 31.3% and 47.6%, respectively, without affecting intakes of dry and organic matter; however, digestibilities of dry and organic matter are negatively affected.
