Characterisation and tanning effects of purified chestnut and sulfited quebracho extracts. [PDF]

Collagen Leather
Vegetable tannins are environmentally friendly tanning agents. However, they generally impart a dark colour to the tanned leather and highly contribute to the organic load in wastewaters.

In vitro effects of different levels of quebracho and chestnut tannins on rumen methane production, fermentation parameters, and microbiota

Frontiers in Veterinary Science, 2023
Both condensed and hydrolysable tannins (CTs and HTs, respectively) have the ability to reduce enteric CH4 production in ruminants. However, the precise mechanism of action is not fully understood.

Effect of Dietary Supplementation of Chestnut and Quebracho Tannin Supplementation on Neonatal Diarrhoea in Preweaning Calves. [PDF]

Antioxidants (Basel)
Neonatal calf diarrhoea (NCD) poses a significant health challenge in cattle herds, resulting in considerable economic losses and antimicrobial use. In response to the escalating threat of antimicrobial resistance, viable alternatives are imperative ...

Effects of a blend of chestnut and quebracho tannins on gut health and performance of broiler chickens

PLoS ONE, 2022
Antimicrobial restrictions prompted the search for cost and biologically effective alternatives to replace antimicrobial growth promoters (AGPs) in food-producing animals.

Renewable Tannin-Based Adhesive from Quebracho Extract and Furfural for Particleboards

Forests, 2022
With increasing concerns about the production of sustainable materials, the field of wood-based materials still offers a critical challenge. Indeed, a close dependence on petroleum derivatives is still required, involving high consumption of non ...

In vitro screening of the ruminal methane and ammonia mitigating potential of mixtures of either chestnut or quebracho tannins with blends of essential oils as feed additives

Italian Journal of Animal Science, 2022
Tannins and essential oils (EOs) have been previously described for their properties to mitigate ruminal methane and ammonia. Their combination might be even more efficient, as they have different modes of action on rumen pathways.

Effect of Select Tannin Sources on Pathogen Control and Microbial Nitrogen Metabolism in Composted Poultry Litter Intended for Use as a Ruminant Crude Protein Feedstuff

Frontiers in Veterinary Science, 2022
Poultry litter is a good crude protein supplement for ruminants but must be treated to kill pathogens before feeding. Composting effectively kills pathogens but risks loss of ammonia due to uric acid degradation. The objectives of this study were to test

Tannins in Mineral Processing and Extractive Metallurgy

Metals, 2015
This study provides an up to date review of tannins, specifically quebracho, in mineral processing and metallurgical processes. Quebracho is a highly useful reagent in many flotation applications, acting as both a depressant and a dispersant.

Reduction of the formaldehyde content in leathers treated with formaldehyde resins by means of plant polyphenols [PDF]

, 2017
Formaldehyde has applications in many industrial processes, including synthesis of resins and syntans to be used in the retanning process of leather. When resins are employed, they can hydrolyse, releasing formaldehyde.

Effects of condensed tannins on goats experimentally infected with Haemonchus contortus. [PDF]

, 2003
Although the use of tanniferous plants or condensed tannins as an alternative to anthelmintics to control gastrointestinal nematodes has been largely documented in sheep, studies remain scarce in goats.
