Use of condensed tannin extract from quebracho trees to reduce methane emissions from cattle.
Our objective was to determine if condensed tannin extract from quebracho trees (Schinopsis quebracho-colorado; red quebracho) could be used to reduce enteric methane emissions from cattle. The experiment was designed as a repeated 3 x 3 Latin square (4 squares) with 3 treatments (0, 1, and 2% of dietary DM as quebracho tannin extract) and 3 28-d periods. Six spayed Angus heifers (238 +/- 13.3 ...
متن کاملResearch Note Sheep Ingestion of Water Containing Quebracho or Black Wattle Tannin
Ingestion of small amounts of condensed tannin (CT) by ruminants can produce valuable outcomes such as improved nitrogen use and reduced bloating, methane output, and gastrointestinal parasitism. However, many grasses and forbs contain little if any CT. The specific types of CT vary in plants and can have somewhat different effects on ruminants. Individual ruminants can respond differently to C...
متن کاملEffect of Quebracho Tannin Drenching on Heligmosomoides Bakeri Infection in Mice
In order to combat the increasing problems of anthelmintic resistance, alternative methods of control of gastrointestinal (GI) nematode infections are being sought. Thirty 8-9 weeks old outbred albino mice were placed in 5 groups of six mice each. Mice in four groups were infected with 150 Heligmosomoides bakeri infective larvae (L3) per mouse while one was reserved as the uninfected control. T...
متن کاملPolyethylene glycol influences selection of foraging location by sheep consuming quebracho tannin.
Tannins are a heterogeneous group of phenolic polymers that can induce detrimental effects when consumed by herbivores. Polyethylene glycol (PEG) binds to tannins and thus attenuates their negative effects. Our objective was to determine whether sheep actively seek PEG when fed tannins and thus modify their foraging location as a function of the spatial distribution of PEG. Lambs were first tra...
متن کاملaccelerated autocondensation of quebracho tannin wood adhesive by boric acid
quebracho tannin wood adhesive in non formaldehyde approach has low autocondensation rate and needs more press time than formaldehyde-based wood adhesives to produce wood composites. in this study, boric acid was used to increase autocondensation rate of quebracho tannin adhesive to make poplar plywood. the main ingredients of the adhesives include quebracho tannin, naoh, hexamine, boric acid a...
