“…Several authors, investigating the influence of the polyphenol extract from chestnut wood, found that the use of these substances in poultry feeding did not affect nitrogen balance, nutrient digestibility, mineral bioavailability, body weight, feed conversion ratio and carcass quality (Salobir et al, 2008;Schiavone et al, 2008;Jamroz et al, 2009). Moreover, chestnut tannins (CTs) are also efficient against coccidiosis and necrotic enteritis in poultry (Elizondo et al, 2010;BoleHribovsek et al, 2012;Tosi et al, 2013). In contrast, little information is reported on the role of CT in laying hens' feeding because most of the studies deal with the use of condensed tannins (Sell et al, 1983;Jacob et al, 1996;Marzoni et al, 2005;Imik, 2009).…”

1. The trial was performed with 80 laying hens belonging to two Tuscan autochthonous breeds: 40 birds of the Mugellese (MU) breed and 40 of the White Leghorn (WL) breed. 2. The animals were allotted to 4 groups of individually caged 20 hens each: two groups were fed on a commercial diet and worked as the control groups (MUC and WLC); the other two groups received the same diet, integrated with 2 g of chestnut tannin (CT) extract per kg of diet (MUT and WLT). 3. A sample of 70 eggs were randomly collected and analysed for cholesterol content, fatty acid (FA) profile, weight, thickness of shell and colour of yolk. 4. Physical parameters, including yolk colour, and indices of egg quality were not affected by the treatments. 5. The concentration of unsaturated FAs increased, whereas cholesterol was significantly decreased: −17% in WLT and −9% in MUT. Dietary supplementation with CT extract resulted in a modification of lipid composition, towards a more healthy quality of eggs.

“…Studies on the effect of tannins on plant parasitic nematodes are few, whereas the studies on tannins as suppressant of gastrointestinal nematodes, bacteria and yeasts are numerous (Scalbert, 1991;O´Donovan & Brooker, 2001;Paolini et al, 2003;Nguyen et al, 2005;Elizondo et al, 2010). In our in vitro experiment, chestnut tannin solutions significantly reduced G. rostochiensis egg hatch during the first fourth weeks in comparison to untreated control.…”

Nematicidal effect of chestnut tannin solutions on the potato cyst nematode Globodera rostochiensis (Woll.) Barhens

108 SummaryRecently, tannins have been reported for their nematicidal activity against the root-knot nematode Meloidogyne javanica both in vitro and in pot experiments in addition to a biocidal effect on a wide range of fungi, bacteria and yeasts. However, no information is available on the effect of these polyphenols on plant parasitic cyst nematodes. Therefore, an in vitro and a pot experiments on potato were undertaken to investigate the nematicidal activity of tannin aqueous solutions at different concentrations on the potato cyst nematode Globodera rostochiensis. In the in vitro experiment different tannin concentrations in a geometric scale (from 0.32 to 20.48 g/l) were tested for their effect on the egg hatch of the nematode. All tested tannin concentrations were effective to reduce egg viability from 56 to 87%, in comparison to the untreated control. In the pot experiment, tannins, as aqueous solutions at rates of 100, 250 and 450 g/m 2 , were applied to soil at two different application times (at sowing and at sowing and two weeks later). All tested doses were effective to reduce the number of cyst/100 g soil, eggs and juveniles/g soil and reproduction rate in comparison to untreated control. The number of eggs and juveniles/cyst was not influenced by the different applied rates of tannins.

“…The source of tannins may also have an impact on their antimicrobial activity against C. perfringens. One study reported that the tannins from chestnut had higher antibacterial activity against C. perfringens than tannins from quebracho plants (72). However, tannins from both chestnut and quebracho could reduce the cytotoxicity of two C. perfringens toxins, alpha toxin and epsilon toxin, in MDCK cells (72).…”

Clostridium perfringens is an important pathogen to human and animals and causes a wide array of diseases, including histotoxic and gastrointestinal illnesses. C. perfringens spores are crucial in terms of the pathogenicity of this bacterium because they can survive in a dormant state in the environment and return to being live bacteria when they come in contact with nutrients in food or the human body. Although the strategies to inactivate C. perfringens vegetative cells are effective, the inactivation of C. perfringens spores is still a great challenge. A number of studies have been conducted in the past decade or so toward developing efficient inactivation strategies for C. perfringens spores and vegetative cells, which include physical approaches and the use of chemical preservatives and naturally derived antimicrobial agents. In this review, different inactivation strategies applied to control C. perfringens cells and spores are summarized, and the potential limitations and challenges of these strategies are discussed.
