Effect of high tannin grain sorghum

Condensed tannins are plant compounds that have been shown to have anti-parasitic activity. However, not all condensed tannins are equal.

Three experiments were conducted at the University of Maryland Eastern Shore (UMES) to determine the influence of high condensed tannin grain sorghum on gastrointestinal parasite fecal egg counts.

Sixteen naturally-infected Boer crossbred mixed-sex goats were used in the experiments. They were fed treatment diets, containing high or low condensed tannin cracked grain sorghum, for 14 or 21 days.

In these studies, high condensed tannin grain sorghum did not consistently influence fecal egg counts and did not impact packed cell volumes or the number of animals requiring chemical anthelmintic treatment.
