“…In the present study, three of the five extracts with a TEP content of ≥40% in DM, namely acacia, grape seed, and green tea, were found to reduce absolute CH 4 emission. The CH 4 mitigation property of Acacia mearnsii bark has already been reported from several experiments, including several in vivo studies [e.g., 5,20]. This had been the reason for using acacia as a positive control and as the extract being present in all binary and 3-way combinations in the present study.…”

Objective The methane mitigating potential of various plant-based polyphenol sources is known, but effects of combinations have rarely been tested. The aim of the present study was to determine whether binary and 3-way combinations of such phenol sources affect ruminal fermentation less, similar or more intensively than separate applications. Methods The extracts used were from Acacia mearnsii bark (acacia), Vitis vinifera (grape) seed, Camellia sinensis leaves (green tea), Uncaria gambir leaves (gambier), Vaccinium macrocarpon berries (cranberry), Fagopyrum esculentum seed (buckwheat), and Ginkgo biloba leaves (ginkgo). All extracts were tested using the Hohenheim gas test. This was done alone at 5% of dry matter (DM). Acacia was also combined with all other single extracts at 5% of DM each, and with two other phenol sources (all possible combinations) at 2.5%+2.5% of DM. Results Methane formation was reduced by 7% to 9% by acacia, grape seed and green tea and, in addition, by most extract combinations with acacia. Grape seed and green tea alone and in combination with acacia also reduced methane proportion of total gas to the same degree. The extracts of buckwheat and gingko were poor in phenols and promoted ruminal fermentation. All treatments except green tea alone lowered ammonia concentration by up to 23%, and the binary combinations were more effective as acacia alone. With three extracts, linear effects were found with total gas and methane formation, while with ammonia and other traits linear effects were rare. Conclusion The study identified methane and ammonia mitigating potential of various phenolic plant extracts and showed a number of additive and some non-linear effects of combinations of extracts. Further studies, especially in live animals, should concentrate on combinations of extracts from grape seed, green tea leaves Land acacia bark and determine the ideal dosages of such combinations for the purpose of methane mitigation.

“…However, the addition of tannin from Acacia mearnsii extracts to the diet of dairy cows did not affect forage intake or total dietary intake, which averaged 11.8 and 17.0 kg/day, respectively. For the concentrate, its intake tended to decrease among the treated animals [13].…”

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).

“…Porém essa suposição não vem sendo confirmada pelos estudos e permanecem desconhecidos os efeitos dos taninos sobre a produção de leite (PILUZZA; SULAS; BULLITTA, 2014). Em um estudo realizado com vacas holandesas suplementadas, de meia lactação, com produção de leite média de 21kg/dia, suplementadas com 120g de tanino provenientes de Acacia mearnsii, não foi observado incremento na produção de leite (ALVES et al, 2017), resultados semelhantes foram obtidos por Griffiths et al (2013).…”

“…Em alguns casos, dependendo da dose, os taninos condensados reduzem a digestibilidade da matéria orgânica. No estudo de Alves et al (2017), por exemplo, as concentrações plasmáticas de ácidos graxos não esterificados encontravam-se aumentadas, o que justifica a ausência de impacto sobre a produção de leite. Faverdin, Hamed e Vérité (2013), acrescentam que só poderiam ocorrer efeitos na produção de leite quando os bovinos estão consumindo quantidades de proteína inferiores as suas necessidades energéticas.…”

Os taninos são compostos fenólicos presentes em plantas, classificados quanto à estrutura química em compostos hidrolisáveis e condensados. Os condensados são adicionados à dieta de ruminantes devido a sua capacidade de formar complexos com proteínas tornando-as não degradáveis no ambiente ruminal. Dessa forma, aumenta o aporte proteico no intestino delgado onde ocorrerá a maior absorção na porção cranial do órgão, o duodeno. A vantagem desse mecanismo é aumentar o aproveitamento da proteína da dieta pelos animais o que influenciará na produtividade e sistema imunológico, entre outros. Os efeitos positivos com a utilização desse composto como aditivo nutricional ainda precisam ser estudados, portanto, o objetivo dessa revisão consiste em demonstrar os resultados, até então conhecidos, da utilização de taninos condensados na dieta de ruminantes.
