Other claims from this paper (19)
- Observation All tropical legume species except Senna siamea contained condensed tannin.
- Observation Acacia boliviana contained less than 55 g total CT per kg dry matter.
- Observation Arachis pintoi contained less than 55 g total CT per kg dry matter.
- Observation Centrosema latidens contained less than 55 g total CT per kg dry matter.
- Observation Senna velutina contained less than 55 g total CT per kg dry matter.
- Observation Gliricidia sepium contained less than 55 g total CT per kg dry matter.
- Observation Other species grown in South America contained 100–240 g total CT per kg dry matter.
- Observation Leucaena species grown in Northern Australia contained intermediate total CT concentrations of 60–90 g per kg dry matter.
- Observation Calliandra calothyrsus grown in Northern Australia contained intermediate total CT concentrations of 60–90 g per kg dry matter.
- Observation Most species contained 70–95% of their total CT as extractable CT.
- Observation Flemingia macrophylla had 60% of its CT extractable, and this value differed between accessions.
- Observation Flemingia macrophylla had 40% of its CT bound.
- Observation Gliricidia sepium had almost all of its CT bound to protein.
- Method / resource Extractable CT determined with vanillin–HCl was generally higher than extractable CT determined with butanol–HCl.
- Method / resource Three accessions showed negligible extractable CT with butanol–HCl but 10–12 g per kg dry matter with vanillin–HCl.
- Intervention effect Oven drying reduced the concentration of extractable CT in Leucaena species relative to freeze drying.
- Intervention effect Oven drying increased the concentrations of bound CT in Leucaena species relative to freeze drying.
- Recommendation The authors suggest that the low-CT species could comprise a reasonable proportion of ruminant diets.
- Recommendation The authors suggest that the other South American species should only be fed in small amounts as supplements to dilute their CT concentration.
