    Wet corn gluten feed and soyhull-steep liquor pellets tended to increase dry matter intake and milk yield. Combining condensed corn steep liquor with raw soybean hulls provides a convenient source of digestible fiber ...
  • Bortone, E. J.; Daccarett, M. G.; Morrill, J. L.; Stevenson, Jeffrey S.; Feyerherm, A. M. (Kansas Agricultural Experiment Station, 2011-08-02)
    Holstein heifers from the Kansas State University Dairy Teaching and Research Unit were used from 3 mo of age until 21 d before estimated date of calving. They were fed either 100 (control, C) or 115% (enhanced, E) of ...
  • Titgemeyer, Evan C.; Shirley, John E. (Kansas Agricultural Experiment Station, 2011-05-06)
    Forty-four Holstein cows were used to measure milk production responses to dryrolled vs processed grain sorghum and expeller vs solvent soybean meal (SBM) in a 2×2 factorial arrangement of four treatments. Processing ...
  • Smith, J. F.; Harner, Joseph P.; Pulkrabek, B. J.; McCarty, D. T.; Brouk, Michael J.; Shirley, John E. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 2011-07-22)

    Sixty Holstein cows averaging 65 days in milk at the initiation of a 13-week study were used to evaluate three alfalfa haylages. Haylages were treated at the time of ensilation with either a Pioneer experimental ...
  • Hartadi, H.; Harbers, L.; Shirley, John E.; Bolsen, K. (Kansas Agricultural Experiment Station, 2011-08-02)
    Whole-plant silage from intercropped grain sorghum and Williams 82 soybean was compared to corn silage in a mixed diet for mid-lactation dairy cows. Cows fed the grain sorghum-soybean silage yielded 45.13 lb and those ...
  • Greenwood, R.H.; Morrill, J.L; Schwenke, J.R. (Kansas Agricultural Experiment Station, 2011-05-05)
