“…These results were consistent with the studies of Cook et al (1995) and Marouani et al (2007) that showed that red wine, tea and other beverages rich in polyphenolic compounds inhibited the absorption of non-heme iron. In addition, in line with our results, supplementation of tannic acid (gallotannin) in the diets of weanling pigs and rats induced the formation of stable polyphenol/iron complexes in the gut having a negative impact on plasma iron concentration (Afsana et al, 2004;Lee et al, 2010). Nevertheless, the precise mechanism by which bioactive dietary polyphenolic compounds inhibit iron metabolism has not been delineated.…”

Polyphenols are chemically and biologically active compounds. Grape seed extracts (GSEs) have been widely used as a human food supplement for health promotion and disease prevention. However, there is little information regarding its application in animal feeds. An experiment was conducted to investigate the effect of inclusion of GSE at 0.025, 0.25, 2.5 and 5.0 g/kg in a wheat soya bean control diet on growth performance, protein and amino acid (AA) digestibility and plasma lipid and mineral concentrations in broiler chickens at 21 days of age. Performance was not affected by dietary treatment except in the case of birds fed the diet with the highest GSE concentration, which showed a worsening of weight gain and feed conversion. Apparent ileal digestibility (AID) of protein was significantly reduced in the birds fed the highest concentration of GSE, which also had a reduction on the AID of arginine, histidine, phenylalanine, cystine, glutamic acid and proline compared with those fed control diet. The inclusion of graded concentration of GSE in the chicken diets caused a significant linear decrease in the concentrations of plasma copper, iron and zinc. Plasma cholesterol, triglycerides and lipoproteins (high-density lipoprotein, low-density lipoprotein and very-low-density lipoprotein) concentrations were not affected by dietary GSE. In conclusion, this study demonstrated that incorporation of GSE in chicken diets up to 2.5 g/kg had no adverse effect on growth performance or protein and AA digestibility. Feed conversion was reduced and growth rate was retarded, when chickens were fed 5 g/kg of GSE. This study also indicated that grape polyphenols reduce the free plasma minerals.

“…Few reports are available regarding CT supplementation in swine diets in general and those measuring effects on mineral digestibility are even rarer. Tannic acid, a hydrolisable tannin, has been shown to reduce Fe availability in weanling pig diets (Lee et al, 2010). Condensed tannins have been used effectively to inhibit iron absorption and mitigate iron overload disorder in multiple exotic species (Wood et al, 2003;Lavin et al, 2010;Lavin, 2012).…”

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.

“…Growth depressing effect of tannic acid has been distinguished in rats (Glick and Joslyn, 1970) and chickens (Kubena et al, 2001). Even in weaning pigs, Lee et al (2010) observed a reduced average daily gain and feed efficiency by consumption of up to 500 mg tannic acid in the diet. During the grower period, BWG of H-SFP fed birds was numerically higher than that of M-SFP birds.…”

The effects of different levels of 0.0 sumac fruit powder (Z-SFP), 0.25 (L-SFP), 0.50 (M-SFP) and 1% (H-SFP) along with 100 mg/kg alpha tocopherol acetate (VE) were investigated on performance and blood antioxidant status of broiler chickens under heat stress condition. L-SFP, M-SFP and VE birds showed higher body weight gain (BWG) than Z-SFP and H-SFP birds during the starter period (P<0.05). No significant differences were observed among the treatments for feed intake (FI) during the starter, grower and whole the experimental periods (P>0.05). Feed conversion ratio (FCR) of M-SFP and VE birds were lower than that of H-SFP birds during the starter period (P<0.05). Moreover, no significant differences were observed for FCR or BWG between the treatments during the grower and whole the experimental periods (P>0.05). The blood total antioxidant capacity (TAC), malondialdehyde (MDA) content and the activity of superoxide dismutase (SOD) and glutathione peroxidase (GPX) enzymes were not affected by dietary treatments at week 6 of age (P>0.05). It was concluded that although dietary SFP consumption can improve the performance of broiler chickens during the starter period under heat stress, it does not affect the performance during grower period or the blood antioxidant indices at week 6 of age.
