“…However, after two weeks, meat from bulls that received tannin supplementation exhibited significantly higher meat thaw loss. Similar conclusions were also reported by Joo et al [59]. They reported that adding chestnut meal at 30 g kg −1 resulted in lower drip loss in pigs.…”

The objective of this study was to investigate the effects of supplementation of hydrolyzable tannins (HT) from sweet chestnut wood extract (Castanea sativa Mill.) to the diet of Limousin bulls on growth rate, carcass and meat quality traits, and fecal Clostridia strain levels in a 7-month feeding trial. Thirty-two bulls were randomly assigned to four treatment groups (CON (without addition of HT); TAN 1 (1 g HT kg−1 DM); TAN 2 (1.5 g HT kg−1 DM); and TAN 3 (1.5 g HT kg−1 DM with a nominally lower dose of concentrate). Compared with the CON group, supplementation with HT significantly (p < 0.050) increased bull growth rate during 4–7 months, whereas carcass and meat quality traits were unaffected during the last three months of fattening. Supplementation of HT significantly reduced meat drip loss (p = 0.000) compared with the CON group. No effects were observed on the total number of fecal Clostridia strains; however, the concentration of Clostridiumperfringens was significantly lower (p = 0.004) in TAN 1 than that in the CON group. The results obtained in fattening bulls indicate that the addition of HT is justified in practice to improve growth performance and feed efficiency without adverse effects on the carcass and meat quality.

“…The values obtained in the microhematocrit did not present statistically significant differences between the groups, in line with previous findings from another group [28]. There were also no significant changes concerning hepatic transaminases, ALT, and AST, suggesting that dietary supplementation with chestnut did not induce hepatotoxicity at the biochemical level.…”

Dietary Supplementation with Chestnut (Castanea sativa) Reduces Abdominal Adiposity in FVB/n Mice: A Preliminary Study

et al. 2020

The production of chestnut (Castanea sativa Miller) is mostly concentrated in Europe. Chestnut is recognized by its high content of antioxidants and phytosterols. This work aimed to evaluate the effects of dietary chestnut consumption over physiological variables of FVB/n mice. Eighteen FVB/n male 7-month-old mice were randomly divided into three experimental groups (n = 6): 1 (control group) fed a standard diet; 2 fed a diet supplemented with 0.55% (w/w) chestnut; and 3 supplemented with 1.1% (w/w) chestnut. Body weight, water, and food intake were recorded weekly. Following 35 days of supplementation, the mice were sacrificed for the collection of biological samples. Chestnut supplementation at 1.1% reduced abdominal adipose tissue. Lower serum cholesterol was also observed in animals supplemented with chestnut. There were no significant differences concerning the incidence of histological lesions nor in biochemical markers of hepatic damage and oxidative stress. These results suggest that chestnut supplementation may contribute to regulate adipose tissue deposition.

“…When a similar extract rich in hydrolysable tannins was used, a dose-dependent influence on productive traits was demonstrated, i.e., no differences when small amounts (up to 2%) of sweet chestnut wood extract were added [33][34][35], whereas an addition of 3% resulted in reduced feed intake, which was attributed to reduced palatability of the diet [36,37]. Supplementing the pigs' diet with a chestnut meal also showed improved performance (feed efficiency) at a lower level of inclusion (30 vs. 50 or 100 g/kg dry matter) [38]. As considered for the supplementation with hops, no effect of feeding diets added with hops water extract on the performance of growing pigs was observed [39].…”

The Effect of Supplementing Pig Diet with Chestnut Wood Extract or Hops on Fresh Meat and Dry-Cured Products

et al. 2020

Oxidation is one of the major reasons for impaired quality of meat and meat products but can be prevented by the addition of antioxidants. In the present study, the effect of dietary sweet chestnut wood extract and hop cones on the quality and oxidative stability of meat and dry-cured products was investigated. Control pigs (N = 11) were fed a commercial diet (13.1 MJ metabolizable energy, 15.5% crude protein), while the other two experimental groups were supplemented with 3% of sweet chestnut wood extract (Tannin; N = 12) or 0.4% of hop cones (Hops; N = 11). The quality of meat and dry-cured products was evaluated by means of chemical composition, water holding capacity, objective color, and lipid and protein oxidation. No major effects of sweet chestnut wood extract or of hops supplementation were observed, nevertheless, some indications of improved water holding capacity could be attributed to antioxidants supplementation. The color evolution of dry-cured bellies from Tannin and Hops groups of pigs during refrigerated storage was also indicative of an improved oxidative stability.
