“…Decreasing the number of days that calves experience diarrhoea, can reduce medical complications, thus involving fewer costs for the farmer and a better future performance (Lorenz et al 2011). These results were in line with findings reported in calves (Bonelli et al 2018;Liepa et al 2018;Gupta et al 2020) where the shortening of the diarrhoeic episode was found in tannin-treated patients. The lack of differences concerning the ADG between the two groups suggests that the tannin powder does not affect the animals' growth.…”

“…Our findings could suggest an initial hepatocellular damage caused by the administration of chestnut tannins in calves, as already reported in calves (Wieland et al 2015). Despite the differences found between the two groups, the serum AST, ALB and GGT and blood methaemoglobin results fell within the normal range, confirming previous findings in neonatal calves (Liepa et al 2018). In our opinion, given an oral dose of 10 g/ calf q24h, of chestnut tannins could be a safe procedure for calves of up to two months old.…”

“…Treated animals showed a later onset of diarrhoea and the degree of diarrhoea was less severe than the non-treated groups. Our results are in line with studies evaluating the administration of tannins in calves affected by neonatal diarrhoea (Kekana 2014;Bonelli et al 2018;Liepa et al 2018;Ranaut et al 2018;Soleiman and Kheiri 2018;Gupta et al 2020). The preventive administration of tannins from the first days of the calf's life improved the faecal consistency score (Soleiman and Kheiri 2018) and the onset of diarrhoea was later than in the control group (Liepa et al 2018).…”

“…One controlled clinical trial reported that dietary chestnut extract administered as 0.02% of body mass had a toxic effect on liver function in newborn calves (Wieland et al 2015). However, feeding tannins in a low to moderate concentration appears to improve the average daily gain (ADG) and the health of the gastrointestinal tract in calves of up to two months old (Liepa et al 2018;Soleiman and Kheiri 2018), and had no negative effect on liver function (Liepa et al 2018).…”

We evaluated the preventive effects of the oral administration of chestnut tannins (Castanea sativa) together with its potential metabolic effect on calf diarrhoea. Forty Italian Friesian female calves were included and divided into Group C (control group) and Group T (tannin-treated group). From the third day of life (T0) for the following 56 days (T56), calves from Group C received 2 L of warm water, while 10 g of chestnut tannin powder extract were added to Group T. Calves were weighed at birth and at T56. Daily faecal score evaluation was performed according to the literature. The age at diarrhoea onset (TDE) and the duration of the diarrhoeic episode were recorded. Blood methaemoglobin and liver enzymes were evaluated weekly starting from T0 to T56 by spectrophotometer and clinical chemistry analysis, respectively. The t-Student and chi-square tests were performed. The TDE was higher (p ¼ .04) in Group T than in Group C (12.0 ± 8.2 and 7.7 ± 3.8 days, respectively). There were no differences for ADG between the groups. Group C spent 24.4% of the whole period with diarrhoea, whereas Group T experienced diarrhoea for 18.9% of the period (p ¼ .001). All the blood and serum analytes were within physiological values. The administration of tannins in calves from the third day of life seemed to delay the onset of diarrhoea by almost four days, suggesting effective preventive action of chestnut tannins. HIGHLIGHTSThe oral administration of chestnut tannins in calves seemed to delay the onset of diarrhoea by almost four days, thus showing a preventive effect. The oral administration of chestnut tannins may lead to a better and shorter recovery of the calf, thus decreasing the use of antibiotics.
