    Clary, E.M.; Brandt, R.T. Jr.; Nagaraja, T.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Batch culture fermentations were used to determine the effects of fat type [none, animal tallow (AT), soybean oil soapstock (SOY), or yellow grease (YG)] and ionophore type [none, lasalocid (L), monensin + tylosin in a ...
  • Effect of Lasalocid or Monensin on feedlot (grain) bloat in cattle
    Bartley, E.E.; Nagaraja, T.G. (Kansas State University. Agricultural Experiment Station, 1983)
    Lasalocid or monensin (600 mg per 1000 lb body weight daily) was tested on cattle bloating on high grain diets. Bloat was reduced 92% by Lasalocid and 64% by monensin. When fed throughout the finishing period, lasalocid ...
  • Effect of level of supplemental alfalfa and its method of processing on intake and utilization of wheat straw
    Lintzenich, B.A.; Cochran, R.C.; Vanzant, E.S.; Beaty, J.L.; St. Jean, G.; Brandt, R.T. Jr.; Nagaraja, T.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
