“…Addition of QTE at 1, 2, and 3% of DM was reported to improve microbial efficiency in sheep fed M. sativa hay (Al-Dobaib, 2009) and Getachew et al (2008) reported improvements only at concentrations of 0.5 and 1%, but not 1.5%. In contrast, QTE infusion at 2, 4, or 6% of DM intake reduced duodenal microbial protein flow by 11, 21, and 39% (Dickhoefer et al, 2016) and up to 36% when QTE was supplemented at concentrations greater than 1% of DM intake (Ahnert et al, 2015).…”

“…Quebracho tannin extract (QTE) is a commercially available CT source from Schinopsis spp., consistently reported to decrease ruminal CP degradation at multiple dietary fiber (Dschaak et al, 2011) and CP levels (Aguerre et al, 2016). Responses appear to be doserelated as increasing inclusion from 1 to 6% of DM linearly decrease ruminal CP degradation (Ahnert et al, 2015).…”

“…Fully grown heifers fed a grass hay and concentrate diet with QTE added at 1-6% of the daily DM intake had reduced apparent total tract CP digestibility at dosages greater than 2%, but impaired digestibility of other nutrients when QTE was greater than 4% (Ahnert et al, 2015). Despite the negative digestibility effect, QTE inclusion improved overall N retention compared with the control, irrespective of the dosage level.…”

“…However, microbial protein production was improved in a birdsfoot trefoil diet suggesting a more efficient use of dietary N when a CT-containing forage was offered in replacement for alfalfa. As rumen NH 3 is reduced, CT shift N excretion from the urine to feces (Deaville et al, 2010;Williams et al, 2011;Hymes-Fecht et al, 2013;Ahnert et al, 2015;Orlandi et al, 2015;Aguerre et al, 2016), which may substantially improve environmental sustainability of ruminant production through reduced nitrous oxide emissions from manure (Powell et al, 2010). The effect of CT on microbial protein synthesis and microbial growth efficiency are much less clear compared with the well-established responses on ruminal CP degradation and NH 3 concentrations.…”

The role of condensed tannins in ruminant animal production: advances, limitations and future directions

-Tannins represent one of the most abundant polyphenolic compounds in plants. Tannins exist as a multitude of chemically unique entities in nature. The most commonly occurring tannins are typically divided into two major classes based on chemical structure: hydrolysable (HT) or condensed tannins (CT). Hydrolysable tannins are esters of gallic or ellagic acid linked to a polyol core, typically glucose. Condensed tannins or proanthocyanidins consist of flavan-3-ol subunits linked together to form oligomers and polymers. Both HT and CT are defined as astringent, medium-to-high-molecular weight polyphenolic compounds that characteristically bind and precipitate soluble proteins. The objective of this paper was to present recent advances in CT-ruminant interactions, the limitations associated with understanding and using CT in ruminant animal production, and future needs for research to further advance our knowledge of the role of CT in optimization of ruminant animal production. Condensed tannins pose some anti-nutritional problems to ruminants due to their astringent property that reduces feed intake and, consequently, animal performance. Ruminants can, however, tolerate CT by slowly adapting the ruminal microbes to the toxic effects of CT and by releasing CT-binding salivary proteins. The protein-binding ability of CT has some benefits to the ruminant due to complexes formed with essential amino acids, preventing their degradation in the rumen, but releasing them in the lower gut for absorption by the animal. Recent data have suggested increased N retention when CT is given to growing animals. There are potential benefits of using CT and HT for anthelmintic purposes due to their ability to inhibit egg hatching and larval motility of gastrointestinal nematode parasites, especially in small ruminants. Condensed tannins also bind to minerals (Al, Ca, Co, Cu, Fe, Mg, Mn, P, and Zn). Although studies with ruminants have been contradictory, it has been reported that because the CT-metal ion complex is stable over a wide pH range, CT may reduce the bioavailability of minerals. Methane mitigation by feeding CT might be the most impactful benefit for ruminant production. Many empirical equations have been developed to predict ruminal methane emissions, but very few have included CT. Future research should focus on the improvement of methodology to assess CT biological activity, interaction with other plant-specialized metabolites, and associated physiological and nutritional impacts on ruminants.

“…Min, Barry, Attwood, and McNabb () described that condensed tannins can reduce proteolysis and N loss during mastication and rumination. Recent studies have reported a linear decrease in urinary N excretion when feeding tannin mix in ruminants (Aguerre, Capozzolo, Lencioni, Cabral, & Wattiaux, ; Ahnert, Dickhoefer, Schulz, & Susenbeth, ; Henke et al., ). Lower urinary N, urinary urea and urea‐N excretion by both low‐ and high‐clove feeding might be related to lower CP degradation in the rumen (Castillo et al., ) that leads to a duodenal flow of undegraded feed protein for digestion in the small intestine.…”

The objective of the study was to evaluate the effects of spices on forage utilization and nitrogen (N) emission using in vitro and in vivo approach. A 6 × 5 factorial triplicate arrangement was used to assess the in vitro degradability of rice straw with control (without spices) and individual (40 mg/g rice straw) spices (cumin, coriander, clove, black cumin, turmeric) at five different incubation times. In vitro dry matter (DM) and organic matter (OM) degradability of rice straw were highest in presence of spices except for clove. Clove significantly reduced the total volatile fatty acids concentration, molar proportion of acetate and propionate ratio, but increased propionate production. Acetate and butyrate production were not affected by treatments. The ammonia-nitrogen concentration was lowest for clove and turmeric compared to other spices. Rumen pH was unchanged but gradually decreased over the incubation period. For in vivo study, 12 bucks with average live weight 7.65 ± 0.19 kg were assigned to a completely randomized design with three treatments and four replicates for a 28-day period. Bucks were fed a total mixed ration without (0 g/kg DM) or with (2.5, 7.5 g/kg DM) clove supplementation. DM intake, body weight and apparent total tract digestibility of crude protein (CP) and acid detergent fibre (ADF) were not affected by increasing dietary doses of clove but tended (p = .09) to increase DM and OM digestibility. The urinary N and urine urea N concentration of bucks decreased linearly with incremental doses of clove diet. In contrary, clove supplementation had positive effects on plasma urea N and retained N in bucks. We concluded that though some spices had positive effects on ruminal digestion and fermentation, the dosage level assessed in the current study (up to 7.5 g/kg DM clove) can be promoted as an effective dietary approach to mitigate N losses in bucks.
