Item Aquatic Plants from Minnesota Part 4 - Nutrient Composition(Water Resources Research Center, University of Minnesota, 1973-04) Goodrich, R.D.; Linn, J.G.; Meiske, J.C.; Staba, E. JohnSamples 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%.Item Aquatic Plants from Minnesota Part 5 - Digestibility and Fermentation of Aquatic Plants(Water Resources Research Center, University of Minnesota, 1974-08) Goodrich, R.D.; Linn, J.G.; Staba, E. JohnThe research was conducted to characterize the fermentation of aquatic plants ensiled with and without additives and to determine the digestibility of dried and ensiled aquatic plants by lambs. Aquatic plants ensiled with the addition of organic acids, corn or haylage produced silages of undesirable quality. Additions of haylage to sterilized aquatic plants before ensiling resulted in a silage of more desirable quality. Dry matter and crude protein digestibilities for sheep fed diets that contained either Myriophyllum exalbescens or Potamogeton pectinatus were lower than for lambs fed dehydrated alfalfa. However, energy digestibility was highest for lambs fed Myriophyllum exalbescens. Mydiophyllum exalbescens appeared to be more palatable than Potamogeton pectinatus, but both were inferior to dehydrated alfalfa. Dry matter intakes of lambs fed ensiled aquatic plants, aquatic plants plus corn or aquatic plants plus haylage were lower than lambs fed either haylage or haylage plus corn diets. Additions of corn and haylage significantly increased aquatic plant organic matter digestibility. Energy and nitrogen digestibilities were lower for lambs fed diets that contained aquatic plants than for lambs fed haylage diets. The palatability of aquatic plants is a limiting factor in their use as a forage. Drying or ensiling do not appear to be satisfactory procedures for improving palatability.Item Association between Vitamin D and Mycobacterium avium subsp. paratuberculosis ELISA status(2012-05-22) Sorge, Ulrike; Wells, Scott; Molitor, Tom; Linn, J.G.; Gallaher, DanielItem DAIRY HEIFER NUTRITION(1995-05-24) Linn, J.G.; Kjome, David J.; Chester-Jones, H.Item Dairy Update: Adding Fat to Dairy Rations - General Considerations, Issue 98(University of Minnesota Extension Service, 1989-12) Linn, J.G.Item Dairy Update: Dry Matter Intake and Feeding Management of Lactating Dairy Cows, Issue 122(University of Minnesota Extension Service, 1995) Linn, J.G.; Otterby, Kuehn; Otterby, D.E.Item Dairy Update: Factors Affecting the Protein and Solids-Not-Fat Content of Milk, Issue 67(University of Minnesota Extension Service, 1983-09) Linn, J.G.; Otterby, D.E.Item Dairy Update: Feeding Wet-Milled Corn Byproducts to Dairy Cows, Issue 66(University of Minnesota Extension Service, 1983-08) Linn, J.G.; Otterby, D.E.Item Dairy Update: Management Of TMR Feeding Programs, Issue 121(University of Minnesota Extension Service, 1995) Linn, J.G.Item Dairy Update: Minerals and Vitamins: Sources, Requirements and Evaluation, Issue 93(University of Minnesota Extension Service, 1989-01) Linn, J.G.Item Dairy Update: TMR Strategies to Optimize Rumen Fermentation, Balancing Rations for Carbohydrates and Protein, Issue 120(University of Minnesota Extension Service, 1995) Linn, J.G.Item Dairy Update: Use Your Minnesota DHI Records, Issue 69(University of Minnesota Extension Service, 1984-11) Mudge, J.W.; Steuernagel, G.R.; Appleman, R.D.; Linn, J.G.; Reneau, J.K.Item The Effects of Forage Quality on Milk Production(1996-05-22) Linn, J.G.; Kuehn, CarlaItem Effects of moderating forage and energy intake in dry cows on periparturient performance and health(2010-05-19) Litherland, N.B.; Linn, J.G.Item Energy in the 2001 Dairy NRC: Understanding the System(2003-05-20) Linn, J.G.Item FEEDING THE EARLY LACTATION COW(1994-05-24) Linn, J.G.; Olson, J.
