  • Laudert, S.B.; Kuhl, Gerry L.; Edwards, A.J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-03)
    Two field trials were conducted to compare the pasture and finishing performance of heifers spayed by the Kimberling-Rupp(K-R) technique or by flank spaying plus autografting a piece of ovarian tissue into the rumen wall ...
  • Hayes, Douglas Kirk; Corah, L.; Bartley, E.E. (Kansas State University. Agricultural Experiment Station, 2011-02-18)
    Data collected from six producers grazing 4050 head of cattle on 850 acres of irrigated alfalfa showed that under optimum conditions, Kansas producers can expect: stocking rate, 5 to 6 head/acre; average daily gain, 2 ...
  • Martin, Victor L.; Hale, R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-08-03)
    Rye, wheat, and triticale pasture were evaluated during the winters of 2000-01, 2001-02, and 2002-03 for their ability to increase cattle weight from late fall through mid-spring. Large-scale studies were conducted on two ...
  • Johnson, Sandra K.; Harmoney, Keith R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2011-03-30)
    Beef producers can lower feed costs by extending the grazing period and reducing the need for harvested forages. Complementary forage systems extend the native range grazing season; wheat pasture is common in the southern ...
  • Schroeder, Ted C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-02)
    Pricing fed cattle on a value-based quality and yield grade grid provides the best opportunity for cattle producers to receive premiums associated with high quality cattle. However, grid discounts for cattle not desired ...
  • Hunt, Melvin C.; Kendall, J.L.A.; Kropf, Donald H.; Dikeman, Michael E.; Kastner, Curtis L. (Kansas State University. Agricultural Experiment Station, 2011-02-09)
    Ground beef from electrically stimulated and/or pre-rigor processed carcasses was equivalent to conventional ground beef in texture, palatability, and frozen storage stability, but lost more juice when vacuum-stored, had ...
  • Naab, J.B.; Seini, S.S.; Gyasi, K.O.; Mahama, G.Y.; Prasad, P. V. Vara; Boote, K.J.; Jones, J.W. (2011-10-07)
    Prior on-station research showed that sowing dates, sowing density and applications of fungicide and phosphorus (P) increased groundnut (Arachis hypogaea) pod yield by 60–80%. Farmer-managed trials were conducted in the ...
  • Steward, David R.; Peterson, Jeffrey M.; Yang, Xiaoying; Bulatewicz, Tom; Herrera-Rodriguez, Mauricio; Mao, Dazhi; Hendricks, Nathan (2012-10-09)
    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. (2012-10-10)
    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. (2012-10-16)
    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.; Kropf, Donald H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07)
    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, Michael E. (Kansas State University. Agricultural Experiment Station, 2011-02-09)
    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, 2010-04-30)
    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, 2010-04-30)
    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 ...
  • Hall, Brandon; Marshall, Jeremy
    Competition for space, resources, and mates plays an important role in the survivorship of many organisms (Sbilordo et al. 2011). Understanding how competition affects a population is a crucial component in ensuring the ...
  • Scheffel, Michael V.; Park, A.; Smith, John F., 1962-; Titgemeyer, Evan C.; Shirley, John E. (Kansas Agricultural Experiment Station and Cooperative Extension Service., 2011-05-04)
    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® consumed ...
  • Chengappa, M. M.; Vorhies, M.W.; Dritz, Steven S.; Nelssen, Jim L.; Tokach, Michael D.; Goodband, Robert D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-03-26)
    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, 2010-10-05)
    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 ...
  • Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07)
    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.
  • Dicke, B.; Erickson, G.E.; Klopfenstein, T.J.; Botts, R.T.; Anderson, P.T.; Depenbusch, Brandon E.; Drouillard, James S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-08-03)
