Aquatic Plants from Minnesota Part 4 - Nutrient Composition. Water Resources Research Center.https://hdl.handle.net/11299/92116Samples of 22 freshwater aquatic plants were analyzed to determine their potential feeding value for ruminants. Proximate analyses (mean +/- SD), on a dry matter basis were: crude protein, 12.7+/-4. 4%; either extract, 1.46+/-.98%; crude fiber, 19.2+/-6.4%; ash, 2.05+/-1.24%; and NFE 64.6+/-6.5%. NDF, ADF, and ADL contents averaged 41.6+/-13.4%; 32.0+/-9.6% and 6.35+/-2.76%, respectively. Mineral contents (mean +/-SD) of the 22 aquatic plants were: P,o.25+/-0.19%; Ca, 1.83+/-1.68%; K, 1.54+/-.92%; Na, 0.30+/-.25%; mg, 0.31+/-.16%; Fe 924=?-730 ppm; Zn, 80.6+/-96.6 ppm; Cu, 13.8+/- 34.0 ppm; Mo, 19.7+/-9.7 ppm and Mn, 269+/-152 ppm. Van Soest's estimated apparent digestibility averaged 63.0+/-8.3%.en-USaquatic plantsproteinfibernutrientsforagecarbohydratesmineralsNewsletter or Bulletin
