    Bock, B.; Brandt, R.T. Jr.; Harmon, D.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Feeding fat increased feed intake and average daily gain, but feed efficiency was not affected. Feeding high levels of calcium (.9%) had no overall effect, but may tend to increase intake when fed with diets that contain ...

    We have measured silage fermentation dynamics in over 50 crops since the development of a 4 x 14 inch PVC pipe, laboratory-scale silo in 1984. In many of these experiments, our objective was to determine how inoculants ...
  • Effect of Foraform® on fermentation of alfalfa, corn, and forage sorghum silages

    Foraform® was evaluated in four trials using alfalfa, corn, and two forage sorghums harvested in 1987 and ensiled in PVC laboratory silos. There was a dramatic crop by Foraform interaction, with Foraform delaying and ...
  • Effect of inoculants and NPN additives on dry matter recovery and cattle performance: a summary of 22 trials
    Bolsen, K.K.; Laytimi, A.; Pope, R.; Riley, J.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Results from 22 trials comparing dry matter (DM) recovery and cattle performance of inoculated or non-protein nitrogen (NPN)-treated silages to controls were summarized using paired t-test analysis. Inoculants consistently ...
  • Effect of limited-creep feeding on performance of spring-born calves: results of 1988 field trials
    Simms, D.D.; Kuhl, G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Two field trials were conducted to evaluate limited-creep feeding of spring- born calves using pelleted creep rations with either 0.5, 5, or 10% salt. Average daily gain was increased (P<.05) over controls in trial 2 and ...
  • Effect of Liquamycin® and Syntabac Plus® on gain and health of stockers purchased as steers or bulls
    Brazle, F.; Kuhl, G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Steer calves gained faster (P<.001) and required fewer treatments per animal (P<.01) than newly castrated bull calves during a 29-day receiving period. Liquamycin® (LA-200) injection at arrival increased steer gains ...
  • Effects of Finapux® in combination with Ralgro® and Synovex® on performance and carcass characteristics of steers and heifers
    Hartman, P.; Kuhl, G.; Simms, D.; Ritter, R.; Houghton, P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Five field trials were conducted with 762 steers and heifers to evaluate Finaplix® in combination with Ralgro® or Synovex® for growing and finishing programs. Effects on cattle performance and carcass characteristics ...
  • Effects of winter herbage removal on Flint Hills rangeland
    Auen, L.M.; Owensby, C.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Intensive-early stocking (lES) in the Kansas Flint Hills has greatly increased livestock production efficiency. The potential for grazing of regrowth on IES pastures the following winter was studied by mowing different ...
  • Evaluation of interseeded grain sorghum and soybeans as a silage crop
    Esmail, S.H.M.; Hartadi, H.; Harbers, L.H.; Shirley, J.E.; Hoover, J.D.; Azimi, S.; Pfaff, L.W.; Bolsen, K.K. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Interseeded grain sorghum and soybeans have been evaluated as a silage crop over a 3year period. In the first 2 years, maximum dry matter (DM) yields occurred at the late-dough stage of the grain sorghum, and interseeded ...
  • Evaluation of wheat middlings as a supplement for cattle consuming winter range forage
    Sunvold, G.D.; Cochran, R.C.; Vanzant, E.S.; Brandyberry, S.D.; Hightshoe, R.B.; DelCurto, T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)

    Hays, T.D.; Brent, B.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Fecal thiaminase was measured on 152 feedlot cattle at three locations and on a variety of rations. No animals showed signs of polioencephalomalacia. Thiaminase activities ranged from 0.6 to 430 µmol thiamin destroyed ...
