“…The adequate amount of water ingested is essential for the health and productivity of ruminants. However, some factors, such as tannins, may promote water consumption (Kronberg & Schauer, 2013). The highest water intake observed in the 5.2% treatment (44.97 L) probably occurred due to the astringent effects of the cows' mouth in concomitant interactions with tannins and salivary proteins.…”

The study aimed to evaluate the effect of adding tannic acid to the diet on the milk quality of cows. The five primiparous crossbred cows (Holstein x Zebu) were used, with about four years old, the average body weight of 420 ± 30 kg, 100 days of lactation initial average production of 18 ± 4 kg of milk/cow/day. The treatments consisted of increasing tannic acid (0; 1.3; 2.6; 3.9 and 5.2%) to replace corn bran in the diet, based on dry matter. The sensory attributes of odor had a significant effect (P < 0.05) of the inclusion of tannic acid in the diet. The odor attributes showed a lower average for the control treatment, and these attributes also showed orthogonal contrast, except the characteristic cow, that is, the control group differed from the treatments as the tannin was introduced, the attribute value became higher compared to the control group. The inclusion of 5.2% tannic acid in dairy cows' diet promoted a slight variation in the taste of milk. However, it did not alter the quality or acceptance of this milk by consumers.

Influence of tannic acid on milk lipid composition of cows

et al. 2022

The study aimed to evaluate tannic acid's influence on lactating cows' diets on milk production and lipid composition. Five crossbred cows (Holstein x Zebu), distributed in a 5 × 5 Latin square, were used to evaluate the effect of increasing tannic acid (hydrolyzable tannin). The diets were composed of 35 kg of corn silage as bulking and 6.38 kg of concentrate. The treatments consisted of increasing levels of tannic acid added to diets (0%, 1.3%, 2.6%, 3.9% and 5.2%). It was observed a decreasing linear effect (P<0.05) of the inclusion of tannic acid in the concentration of saturated butyric fatty acids (C4:0) presenting a mean of (2.99), and quadratic effect in the concentration of saturated fatty acids lauric (C12:0) presenting mean (26.74). The addition of tannic acid had effects on saturated fatty acids, decreasing the concentrations of butyric acid and increasing the concentrations of lauric acid. Atherogenicity and thrombogenicity rates reveal the potential for the prevention of coronary heart disease. However, the observed changes do not compromise the milk's chemical composition and nutritional quality,the y nutritional quality of the milk, presenting possibilities of human health benefits, thus enabling the aggregation of value for these products.

“…Tannins are usually associated with decreased palatability and, consequently, with an influence on the time spent eating. However, moderate amounts of some types of tannins ingested by ruminants have the potential to improve productivity and dietary protein utilization efficiency in the small intestine, to reduce the negative impact of gastrointestinal parasites, and to reduce urea excretion via urine and methane emission into the environment [4][5][6].…”

Feeding Behavior of Lactating Dairy Cattle Fed Sorghum-Based Diets and Increasing Levels of Tannic Acid

et al. 2021

Tannins have been used to trigger positive effects on ruminal metabolism and increase ruminant production efficiency, since they increase the supply of dietary protein in the small intestine. Increasing levels of tannic acid in a sorghum-based diet on the feeding behavior of five Holstein/Zebu crossbred lactating dairy cows was evaluated. They were subjected to a 5 × 5 Latin square experimental design, with fivelevels of tannin as dry matter (DM) in the diet (0.46, 1.30, 2.60, 3.90, and 5.20%). The levels of the tannic acid added were established based on the quantity of condensed tannin in high-tannin sorghum. Thus, diets 2, 3, 4 and 5 were supplemented with 1.5 g (13% DM), 79.5 g (2.6% DM), 157.5 g (3.9% DM), and 235.5 g (5.2% DM) of tannic acid, totaling 0.078, 0.156, 0.234, and 0.321 kg of tannin/day, respectively. Feeding behavior variables included the following states and events: feeding, drinking, rumination, and inactivity; the frequency of visiting the feed and water troughs; and the occurrence of urination and defecation. Water was provided ad libitum, and its intake was measured during periods of behavioral data collection. The use of two tannin sources (hydrolysable and condensed) corresponding to the total level of 5.20% (on a DM basis) in the diet of lactating dairy cattle does not affect the animals’ health. Tannic acid can be included in the diet of lactating dairy cattle at a level of 3.93% (on a DM basis) without inducing variation in the total time spent daily on feed intake. Dairy cows dilute the effects of dietary tannin (5.20%) through greater fragmentation of food consumption in the hours following its supply (180 min). The astringent effects caused by tannin intake in lactating dairy cows are mitigated by increasing the daily water intake as the amount of tannin in the diet increases, starting at a level of 3.90% tannin (on a DM basis).
