“…Results suggest that SHE did not target any specific proteolytic steps in the rumen, but numerically (P 00.10) reduced bacterial protein production, which explained the lack of difference in NH 3 -N between control and SHE. These observations are consistent with the previous report of Krueger et al (2010) that a high-grain diet with condensed or hydrolysable tannins (14.9 g tannins extracts kg…”

Effect of sainfoin hay and pomegranate peel extracts on in vitro fermentation and protein degradation using the RUSITEC technique. Can. J. Anim. Sci. 95: 417Á423. The objectives of this study were to determine the effect of supplementation of sainfoin hay extract (SHE) and pomegranate peel extract (PPE) on in vitro rumen fermentation characteristics, protein metabolism and nutrient digestibility using rumen simulation technique (RUSITEC). The experiment was a completely randomized design with three treatments and four replications. Dietary treatments were: (1) control (10% barley silage and 90% concentrate), and control supplemented (2) with SHE (4.1 g catechin equivalent kg(1 dry matter; DM) or (3) with PPE (2.8 g tannic acid equivalents kg(1 DM). The experiment consisted of 10 d of adaptation and 7 d of data collection. Concentration of total volatile fatty acid (VFA) was lower (PB0.02), but molar proportion of acetate was higher (PB0.01) with SHE or PPE than control. Branched-chain VFA decreased (PB0.01) with PPE supplementation compared with control. Concentrations of large and small peptides were not affected but ammonia nitrogen (NH 3 -N) concentration decreased (P B0.01) with PPE supplementation. Digestibility of DM, starch and crude protein decreased (PB0.02) with SHE and PPE supplementation compared with control. Bacterial nitrogen production (mg d(1 ) and bacterial efficiency (g bacterial nitrogen kg(1 digested organic matter) were not affected by SHE or PPE supplementation. Overall, there were no differences in VFA concentrations, nitrogen fractions and nutrient digestibility between SHE and PPE except for the concentrations of branched-chain VFA and NH 3 -N, which were higher (PB0.01) with SHE versus PPE supplementation. In conclusion, supplementation of high-grain diet with SHE or PPE can decrease rumen by-pass protein; however, suppression of feed fermentation may decrease the feeding value of high-grain diet.

“…Tannins are able to change microbial populations, which can alter the digestibility of nutrients and then the production of VFAs and NH 3 -N (Kruegera et al, 2010). In the present study, the higher levels of PBPS (12PBPS and 18PBPS) decreased total VFA and NH 3 -N concentrations compared with the control group.…”

The objective of this study was to determine the effects of pistachio by-product silage (PBPS) as a partial replacement for corn silage (CS) on chewing activity, nutrients digestibility and ruminal fermentation parameters in Holstein male calves over a 6-month assay. For this purpose, 24 Holstein male calves (4 to 5 months of age and 155.6 ± 13.5 kg BW) were randomly assigned to one of the four dietary treatments (n = 6). In these treatments, CS was substituted with different levels of PBPS (0%, 6%, 12% and 18% of dry matter (DM)). Nutrient digestibility was measured at the end of the experimental period (days 168 to 170). Ruminal fermentation parameters were determined on days 90 and 180 and chewing activity was determined on days 15 of the 3 rd and 6 th month of the experiment. Results showed that calves fed rations containing 6% PBPS spent more time ruminating ( P < 0.05) than the control group on the 3 rd and 6 th months. Feeding PBPS was found to have no effects on DM, organic matter (OM), ether extract or ash digestibility, but apparent digestibility of CP, NDF om and ADF om linearly decreased ( P < 0.01) with increasing substitutions. On days 90 and 180, ruminal concentrations of volatile fatty acids and NH 3 -N linearly decreased ( P < 0.01) with increasing levels of PBPS in the diets; however, ruminal pH and molar proportions of acetate, propionate and butyrate were similar across the treatments. It was concluded that partial substitution of CS with PBPS (6% or 12%) would have no adverse effects on nutrient digestibility, total chewing activity and ruminal fermentation parameters.

“…Similar responses in DMI to tannin supplementation of higher forage diets have been also reported in feeding trials involving goats (Puchala et al 2005), lambs (Douglas et al 1995), and in cows (Woodward et al 2000). In contrast, Krueger et al (2010) and Mezzomo et al (2011) did not observe effects of supplemental tannins (1.5% and 0.4% of diet, respectively) on DMI of finishing feedlot steers. High levels of dietary tannin (> 5% tannins of diet) have markedly depressed feed intake in ruminants (Frutos et al 2004).…”

Two trials were conducted to evaluate the effect of tannin supplementation of steers during the feedlot finishing phase. In Trial 1, 96 Holstein steers (478 ± 6.5 kg) were used to evaluate the effects of level of supplemental condensed tannin (0%, 0.2%, 0.4%, and 0.6% of dry matter basis) on growth performance. Supplemental tannin increased (6.5%, P = 0.05) weight gain, gain efficiency (5.5%, P = 0.04), and tended to increase dietary net energy (3.2%, P = 0.06). In Trial 2, 96 Holstein steers (392 ± 4 kg) were used to evaluate the effect of tannin sources on growth performance. Treatments consisted of a steam-flaked corn diet supplemented with (1) no supplemental tannin, (2) 0.6% condensed tannin, (3) 0.6% hydrolysable tannin, and (4) a blend of 0.3% condensed and 0.3% hydrolysable tannin. Tannin supplementation tended to increase average daily gain (ADG, 6.8%, P = 0.08) and dry matter intake (DMI, 4%, P = 0.04). It is concluded that tannin supplementation promotes greater DMI, and hence, ADG of steers during the finishing feedlot phase. The basis for this effect on feed intake is not certain, but is apparently independent of potential tannin effects on metabolizable protein supply. Source of supplemental tannin (condensed vs. hydrolysable) have minimal effects on overall growth performance response to supplementation. ARTICLE HISTORY
