“…26,27 Decreased N mineralization and especially nitrification by tannins have potential in mitigating N 2 O emissions. 28 Mechanistically, tannins affect soil N transformations, probably mainly via protein binding. Because enzymes are proteins, hydrolyzable and condensed tannins may also affect enzymatic activities, which catalyze biochemical reactions.…”

The interaction between tannins and proteins has been studied intensively for more than half a century as a result of its significance for various applications. In chemical ecology, tannins are involved in response to environmental stress, including biotic (pathogens and herbivores) and abiotic (e.g., drought) stress, and in carbon (C) and nutrient cycling. This perspective summarizes the newest insights into the role of tannins in soil processes, including the interaction with fungi leading to C stabilization. Recent knowledge presented here may help to optimize land management to increase or preserve soil C to mitigate climate change.

“…High tannin concentrations in ruminants are known to reduce palatability, feed intake, and degradability [ 34 ], while low tannin concentrations are known to have health benefits such as antiviral and antibacterial effects [ 62 ]. In relation to greenhouse gases, tannins are regarded as an important alternative in mitigating carbon dioxide (CO 2 ), as well as methane (CH 4 ) [ 63 ]. The same authors found that the addition of tannins into Nellore bulls’ urine had an effect on the reduction in CH 4.…”

A cost-effective, alternative protein and mineral source such as the Viscum species can be key to livestock production. Viscum spp. are used as feed in many semi-arid and arid regions globally, particularly during feed shortages. The species’ feeding value, and their pharmaceutical attributes, have been recognized worldwide, albeit with variation in nutritive value from one host to another. The antinutritional factors found in Viscum spp. may benefit livestock when consumed in moderation due to their immunomodulatory, proapoptotic, and antimicrobial properties. The Vachellia species are known to be the common hosts for Viscum spp. Further, even though Viscum spp. inhibit host tree development by reducing carbon absorption and the host tree’s carbohydrates, the efforts to regulate their infestation should not result in the plant’s total eradication due to the benefits to livestock (as well as in fodder and medicine). This review will help to improve understanding of Viscum species control measures, while also increasing the productivity of ruminants.

“…One option to address this environmental impact is supplementation with supplements that increase the efficiency of N usage by the animals. Animal supplementations have been shown to affect feed digestibility and N metabolism in the animal, providing a better ruminal fermentation and absorption of nutrients such as nitrogen (N), thus reducing emissions from animal excreta [10,18,19].…”

“…Using tannin extracts or feed that has tannins may alter the excretion pathways of N and binding proteins and reduce the ruminal protein degradation [19,25]. In addition, tannins act on ruminal microorganisms, reducing bacterial hydrolytic activities, which may decrease N excretion via urine and can be an alternative to reduce N 2 O emissions.…”

Animal supplementation during the background phase may increase greenhouse gas emissions (GHG). The inclusion of tannins in the diet of Nellore bulls can mitigate nitrous oxide (N2O), methane (CH4), and ammonia (NH3) production. The objective of this study was to quantify the effect of energy supplementation associated with sources of tannins in the diet of young Nellore bulls backgrounded in pastures with N2O, CH4, and NH3 emissions. Two experiments were conducted in a completely randomized design. The treatments were three supplementation strategies: (1) soybean hulls 0.3% of body weight (BW), (2) sorghum grain 0.3% of the BW, and (3) peanut peel 0.3% of BW, the last two being sources of tannin. The static closed chambers method was used to quantify N2O and CH4 emissions and the semi-open chamber technique to estimate NH3 volatilization. Supplementation strategies did not affect the N2O emissions (p = 0.9116). The soil water-filled pore space explained the variation in the N2O fluxes (p = 0.0071). The treatments did not change the total CH4 emissions (p = 0.3599), and no explanatory variable was correlated with the CH4 fluxes. The NH3 volatilization did not vary according to the supplements or tannin inclusion (p = 0.5170). However, the type of excreta affected the NH3 volatilization (p < 0.0001). Ammonia volatilization averaged 14.05, 4.16, and 2.25% of the applied N for urine, urine + dung, and dung, respectively. The energetic supplementation of Nellore bulls containing sources of tannins in the evaluated dosages was not a mitigation strategy for the emissions of N2O, CH4, and NH3.
