Other claims from this paper (15)
- Observation Salix nigra leaves had a seasonal average condensed tannin level of 17.9.
- Observation Salix alba leaves had a seasonal average condensed tannin level of 18.5.
- Observation Purified condensed tannins of S. nigra had a procyanidin/prodelphinidin ratio of 59/41.
- Observation Purified condensed tannins of S. nigra had a cis / trans ratio of 59/41.
- Observation Purified condensed tannins of S. nigra had an estimated mean degree of polymerization of 8.1.
- Observation Purified condensed tannins of S. alba had a procyanidin/prodelphinidin ratio of at least 99/1.
- Observation Purified condensed tannins of S. alba had a cis / trans ratio of 85/15.
- Observation Purified condensed tannins of S. alba had an estimated mean degree of polymerization of 6.9.
- Association The condensed tannin content of S. nigra trended higher with seasonal growth, and this trend was statistically significant.
- Association The condensed tannin content of S. alba trended higher with seasonal growth.
- Association The condensed tannin content of P. nigra trended lower across all three locations, without statistical significance.
- Association The condensed tannin content of H. rhamnoides trended lower across all three locations, without statistical significance.
- Observation Condensed tannins were insignificant in the leaves of Elaeagnus angustifolia.
- Observation S. nigra likely contains adequate condensed tannin levels to bolster nitrogen use efficiency in ruminants without a detrimental effect on dry matter intake.
- Observation S. alba likely contains adequate condensed tannin levels to bolster nitrogen use efficiency in ruminants without a detrimental effect on dry matter intake.
