“…Monteleone et al (2004) had studied the astringency intensity rating of TA using human subjects and had reported a steep increase in the intensity of perceived sensation of astringency with an increase in the concentration of TA from 0.32 to 1.63 g/L. However, it has also been suggested that a slightly astringent taste may increase the palatability of feed and stimulate feed intake (Gupta and Haslam, 1980;Santidrian and Marzo, 1989). The results of our study suggest that TA may have reduced the palatability only for a short duration (during days 0 to 14 as observed in the current study), and pigs may adapt to the presence of TA in the diet (during days 15 to 28 the ADFI was comparable among treatments).…”

“…It has been demonstrated that inclusion of feed ingredients containing tannins resulted in undesirable physiological and biochemical effects (Armstrong et al, 1974;Smulikowska et al, 2001) including growth inhibition, negative nitrogen balances, reduced intestinal absorption of sugars and amino acids, reduced immune response, and increased protein catabolism (Santidrian, 1981;Santidrian and Marzo, 1989;Marzo et al, 2002). However, with better understanding of the chemical composition and biological activity of tannins (Mueller-Harvey, 2006), tannin is now known to play a beneficial antioxidant role, preventing lipid peroxidation (Laughton et al, 1991;Morel et al, 1993;Caraceni et al, 1997;Lopes et al, 1999;Rajalakshmi et al, 2001;Glahn et al, 2002) reported that at 0.5% inclusion rate, chestnut tannins had positive effects on carcass characteristics, meat quality, lipid oxidation and fatty acid composition in rabbits.…”

One hundred twenty day-old broiler chicks (Cobb 500) were randomly assigned into 4 treatment groups to investigate the effects of tannic acid supplementation (TA) on fatty acid composition in breast muscle of broilers under chronic heat exposure conditions. Five pen replicates of 6 chicks each were assigned to each of the following 4 dietary treatments: i) basal diet containing no TA at 25°C (CL); ii) basal diet containing no TA at 35°C (CH); iii) basal diet supplemented with 1% TA at 25°C (TL); and iv) basal diet supplemented with 1% TA at 35°C (TH). At the end of the 5-week experiment, breast muscle samples were collected to examine the fatty acid composition. Results showed that temperature, TA and their interaction effect significantly decreased body weight gain and feed intake. In addition, feed conversion ratio (FCR) significantly increased under high temperature, and addition of TA under high temperature did not improve the FCR. The effects of temperature, TA and their interaction on the saturated and unsaturated fatty acids were not significant (P>0.05). However, monounsaturated fatty acids significantly reduced by adding TA to the diet. Generally, TA improved the fatty acid profile of breast muscle of broilers under heat stress in comparison to the heat stressed chickens, which did not receive TA. Hence, it seems that dietary TA supplementation can be applied as a biological antioxidant for poultry nutrition in hot climatic conditions.

“…We also investigated the effect of TA on cecal fermentation which plays a role in absorption. In Experiment 1, to set the optimum dose of Fe, male Sprague-Dawley rats (weighing 70-90 g) after acclimatization were fed with different levels of dietary Fe (5,10,20,30 and 35 mg/ kg). We observed that the hematocrit (Ht), serum Fe concentration and transferrin saturation (%) were each reduced in those rats fed less than 20 mg/kg Fe in a dose-dependant manner.…”

Interest in the beneficial effects of polyphenols, including tannic acid (TA), is increasing, although, these compounds also have adverse effects; for example, on the absorption of iron (Fe), and possibly other trace minerals. We examined the effect of a graded dose of TA on the absorption of Fe and compared with that of zinc (Zn), copper (Cu) and manganese (Mn) in rats. We also investigated the effect of TA on cecal fermentation which plays a role in absorption. In Experiment 1, to set the optimum dose of Fe, male Sprague-Dawley rats (weighing 70-90 g) after acclimatization were fed with different levels of dietary Fe (5, 10, 20, 30 and 35 mg/kg). We observed that the hematocrit (Ht), serum Fe concentration and transferrin saturation (%) were each reduced in those rats fed less than 20 mg/kg Fe in a dose-dependent manner. In Experiment 2, the rats were fed with test diets containing the minimum required level of Fe, 30 mg/kg diet, with (5, 10, 15 and 20 g/kg diet) or without TA for a period of three weeks. Feeding a diet containing more than 10 g TA/kg diet, but not 5 g TA/kg diet, reduced the hemoglobin concentration (Hb), Ht and serum Fe concentration due to decreased Fe absorption. In contrast, the Zn, Cu and Mn absorption was not affected by TA feeding. It is also demonstrated that liver Fe, but not the Zn, Cu and Mn contents, were lower in the TA groups than in the TA-free control group. Feeding TA slightly decreased the pH value of the cecal contents with an increase in the major short-chain fatty acid pool. About 15% of the ingested TA were recovered in the feces of each TA-fed group. Our results demonstrate that more than 10 g TA/kg diet induced anemia by reducing the Fe absorption, although there was no effect on the absorption of other important trace minerals. Our findings suggest that the usual intake of polyphenols is relatively safe, but that a high intake by supplementation or by dietary habit of tannin affects only the Fe level.
