Concentration of Soluble Condensed Tannins and Neutral Detergent Fibre-bound Tannins in Fodder Trees and Forage Crops in Botswana

O. Phale and O.R. Madibela

Abstract:
This study was conducted to determine soluble and fibre-bound condensed tannins in fodder trees and forages used in ruminant feeding in Botswana. Samples of Acacia nilotica and A. robusta were obtained from paddocks at Content Farm while Lablab purpureus (Lablab) was obtained from dried hay bales and Ipomoea batatas (sweet potato) was sourced from Department of Agricultural Research. Acacia and sweet potato vine samples were dried under shade before been ground and analysed for soluble tannins and fibre-bound tannins. It was found that amounts of soluble and fibre-bound tannins were different between plant species. There was a highly significant (p<0.001) plant effect on soluble tannins. A. nilotica had the highest levels while Ipomoea batatas had the least amounts. The fibre-bound tannins was significantly different (p<0.01) between plant species. Once again A. nilotica had high levels while sweet potato had the least. However A. robusta and Lablab had similar (p>0.05) amounts of fibre-bound tannins. The level of soluble tannins in acacia species may interfere with animal performance since they exceed 50 g kg-1. However, goats may be able to utilise these plants as no sign of toxicity was found in goats consuming 10-23 g kg-1 of tannins-rich leaves in Israel.
