Research 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...

Polyethylene 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...

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 ...

In vitro effect of condensed tannin extract from acacia (Acacia mearnsii) on gastrointestinal nematodes of sheep.

The aim of this study was to determine the inhibitory effects of condensed tannin extract from acacia on the feeding of first-stage larvae (L1) of Haemonchus contortus, Trichostrongylus vitrinus and Teladorsagia circumcincta. The experiment was developed such that the inhibition of feeding for each of the nematode species could be evaluated. L1 recovered from fecal samples from a donor with mon...

Effect 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...
