  • Steward, David R.; Peterson, Jeffrey M.; Yang, Xiaoying; Bulatewicz, Tom; Herrera-Rodriguez, Mauricio; Mao, Dazhi; Hendricks, Nathan (2009)
    An integrated foundation is presented to study the impacts of external forcings on irrigated agricultural systems. Individually, models are presented that simulate groundwater hydrogeology and econometric farm level crop ...
  • Saak, Alexander E.; Peterson, Jeffrey M. (2012)
    Farm size is a significant determinant of both groundwater irrigated farm acreage and groundwater irrigation application rates per unit land area. This paper analyzes the patterns of groundwater exploitation when resource ...
  • Saak, Alexander; Peterson, Jeffrey M. (2007)
    This paper introduces a game theoretic model of groundwater extraction in a two-cell aquifer under incomplete information. A novel assumption is that individual users have incomplete knowledge of the speed of lateral flows ...
  • Koch, B.A.; Hines, R.H.; Kropf, D.H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    The need for zinc in swine rations has been firmly established. Likewise the inter-relationships between dietary zinc and other minerals, especially calcium, have been well authenticated. However, there are still many ...
  • Ilg, H.; Bolsen, K.; Dikeman, M. (Kansas State University. Agricultural Experiment Station, 1981)
    Growing rations containing forage sorghum silage (FSS) or equal amounts of FSS and alfalfa haylage were fed to crossbred steer calves for 112 days. Steers consumed more of the FSS + haylage but rate and efficiency of ...
  • Greig, J.K.; Spillman, C.K.; Koch, B.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Exhaust air from a Kansas State University swine-farrowing house provides CO2 and possibly other gases that are being used by vegetable plants in a KSU greenhouse. In addition, a rock-storage system reduces fuel requirements ...
  • Greig, J.K.; Spillman, C.K.; Koch, B.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1981)
    Exhaust air from a Kansas State University swine-finishing house provides C02 and possibly other gases that are being used by vegetable plants in a KSU green house. In addition, a rock-storage system reduces fuel requirements ...
  • Shirley, J.E.; Scheffel, M.; Park, A.; Smith, J.F.; Titgemeyer, E.C. (Kansas Agricultural Experiment Station and Cooperative Extension Service., 1998)
    Ninety Holstein heifers were used to examine the effects of Rumensin® or Bovatec®. Average daily gain and feed efficiency was greater for heifers fed Rumensin® than for heifers fed Bovatec®. Heifers fed Rumensin® ...
  • Dritz, S.S.; Chengappa, M.M.; Nelssen, J.L.; Tokach, M.D.; Goodband, R.D.; Vorhies, M.W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    Seventy pigs, 7 to 10 d of age, were randomly selected by litter of origin from a commercial farm in Northeast Kansas to compare the growth and microbiology of nonmedicated, segregated, early-weaned pigs to controls ...
  • Peters, C.W.; Brazle, F.K.; Corah, L.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    Heifers developed on high-endophyte, tall fescue gained half as much weight (56 vs 117 lb; P<.01) and had a lower 35-day pregnancy rate (15 vs 58%; P<.01) compared to heifers fed low endophyte, tall fescue. Based ...
  • Hines, R.H.; Koch, B.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1970)
    Mixing litters after weaning did not significantly affect rate of gain or efficiency of growing pigs. Weight gains were similar (1.57 or 1.49) for mixed litters and intact litters during a 28-day post-weaning trial.
  • Depenbusch, B.E.; Drouillard, J.S.; Dicke, B.; Erickson, G.E.; Klopfenstein, T.J.; Botts, R.T.; Anderson, P.T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Component TE-S and Component TE-S with Tylan growth-promoting implants were compared in an experiment conducted at a commercial feedlot operation (Ward Feed Yard; Larned, Kansas) to evaluate effects on growth performance ...
  • Hildabrand, B.M.; Burkey, T.E.; Skjolaas, K.A.; Dritz, S.S.; Johnson, B.J.; Minton, J.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Weaned pigs (n = 240; initial BW 13.5 lb) were used in a 28-d growth study. Pigs were blocked by sex and BW, and were assigned randomly to 1 of the 5 dietary treatments: control (no added antimicrobials or yeasts), Neo- ...
  • Hildabrand, B.M.; Neill, C.R.; Burkey, T.E.; Dritz, S.S.; Johnson, B.J.; Minton, J.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    A total of 210 pigs were used in a 28-d growth study to evaluate the effects of feeding the combination antibiotic neomycin and oxytetracycline (Neo-Terra), different rates of BIOSAF yeast (0.15% or 0.3%), and the combination ...
  • Hildabrand, B.M.; Burkey, T.E.; Skjolaas-Wilson, K.A.; Dritz, S.S.; Johnson, B.J.; Minton, J.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2005)
    A total of 280 pigs were used in a 28-d growth study to evaluate the effects of feeding the antimicrobial carbadox, BIOSAF (0.4%), and the combination of carbadox and BIOSAF yeast (0.15%) in nursery pig diets. Over the ...
  • Wooten, E.L.; Broce, A.B.; Blecha, Frank (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1985)
    Two trials were conducted to determine the effect of sarcoptic mange on growth performance of pigs. Results from previous experiments with weaned pigs artificially infested with sarcoptic mites indicated no alteration of ...
  • Swanson, J.A.; Hancock, J.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Two hundred fifty-five pigs, weaned at 4 wk of age, were used in an experiment to compare the efficacy of Bacillus subtilis and antibiotics as growth promoters for swine from nursery to finishing. Treatments were a ...
