  • Langemeier, Michael R.; Mintert, J.; Schroeder, Ted C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    This study examined the impact of date of feedlot placement on feed conversion, daily gain, and death loss. Results indicated that heifers placed on feed from September to December required more feed per pound of gain, ...
  • Mintert, J.; Langemeier, Michael R.; Schroeder, Ted C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Analysis of 10 years of closeouts from a western Kansas feedlot demonstrated that steer performance exhibits significant seasonal variation. Steers weighing 700 to 800 lb when placed on feed in September through ...
  • Cochran, R.C.; Vanzant, E.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Concentration of fiber in the forage selected by beef steers grazing bluestem range during a drought year (1989) was highest in the winter but declined substantially in the spring and remained fairly constant throughout ...
  • Schalles, R.R.; Blum, J.K.; Smith, W.H. (Kansas State University. Agricultural Experiment Station, 1977)
    Selecting animals for decreased feed per unit of gain has made small changes in feed conversion over a four-year period. Adjusting for maintenance requirements by using mid weight to 0.75 power was not entirely satisfactory ...
  • Wheat, J.D.; Kropf, Donald H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1975)
    Litters farrowed total 147 (25 in 1971, 23 in 1972, 33 in 1973, 32 in 1974 and 34 in 1975); pigs total 1196, 1102 alive at birth 94 (8%) dead at birth. Line differences in loin eye area, backfat thickness and age (adjusted ...
  • White, J.; Bolsen, K.; Kirch, B.; Pfaff, L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1988)
    Eighty forage sorghum cultivars were compared in 1986 for agronomic and silage quality traits. Silage yield ranged from 5.3 to 10.0 tons (t) of dry matter (DM) per acre (mean, 7.4 t); grain yield, from 13 to 113 bushels ...
  • Healy, B.J.; Bramel-Cox, P.J.; Richert, B.T.; Klopfenstein, C.F.; Witt, Merle D.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Six cannulated barrows and two hundred eighty-eight chicks were used in an experiment to determine the value of an in vitro protein digestibility assay (pepsin digest) for identification of sorghum parent lines with ...
  • Healy, B.J.; Bramel-Cox, P.J.; Richert, B.T.; Klopfenstein, C.F.; Witt, Merle D.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Six cannulated barrows and two hundred eighty-eight chicks were used in an experiment to determine the value of an in vitro protein digestibility assay (pepsin digest) for identification of sorghum parent Iines with ...
  • Wheat, J.D.; Kropf, Donald H.; Na-Lampang, P.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1978)
    Select line pigs were compared with those in the control line for growth patterns, production traits, and carcass quality. Heritability and genetic correlations were calculated for certain production and carcass traits ...
  • Wheat, J.D.; Kropf, Donald H.; Chang, C.H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1974)
    Line differences in weight, litter size at different ages, and in age, loin eye area, and backfat thickness of pigs (adjusted to 200 pounds live weight) were not significant. Sex differences in weight and backfat thickness ...
  • Sinha, Deepak K.; Smith, C. Michael (2014)
    The Russian wheat aphid (RWA), Diuraphis noxia Kurdjumov, is a major global pest of wheat and barley production that causes enormous economic damage. Few studies have been conducted to explore and decipher the molecular ...
  • Glaze, J.B. Jr.; Schalles, R.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1995)
    Performance records of 1459 Polled Hereford cattle born from 1967 through 1979 were analyzed to estimate genetic parameters and the direct and correlated responses that were due to selection for feed conversion. Her ...
  • Glaze, J.B. Jr.; Schalles, R.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Direct and correlated responses to selection for improved feed conversion were estimated from performance records of 1459 Polled Hereford cattle born from the spring of 1967 through the spring of 1979. Data were ...
  • Premarathna, Lakmalie; McLaughlin, Mike J.; Kirby, Jason K.; Hettiarachchi, Ganga M.; Stacey, Samuel; Chittleborough, David J. (2012)
    We examined the effects of applied selenium (Se) species, time of application, method of application and soil water management regime on accumulation of Se in rice plants. Plants were grown to maturity in a temperature- ...
  • Harbers, L.H.; Sapienza, D.A.; Schwanke, L.; Kazemi, S.M.; Smith, E.F. (Kansas State University. Agricultural Experiment Station, 1981)
    We used steers with esophageal cannulas to measure selenium in burned and unburned bluestem pastures between May and September. Individual variation among steers sampled varied as much as two fold in selenium content. ...
  • Pickett, A.G.; Smith, E.F. (Kansas Agricultural Experiment Station, 1949)
    Considerable interest has developed in the possibilities of self feeding a protein supplement to cattle on grass. Self feeding is a labor saving and eliminates the need for rounding up cattle every day. Under usual ...
  • Richardson, D.; Smith, E.F.; Koch, B.A.; Cox, R.F.; Boren, Fred W. (Kansas Agricultural Experiment Station, 1959)
    Forty Hereford heifer calves from the same herd were divided as equally as possible on the basis of weight and conformation into four lots of 10 animals each. Animals in all lots received all the sorghum silage they would ...
  • Richardson, D.; Smith, E.F.; Koch, B.A.; Cox, R.F. (Kansas Agricultural Experiment Station, 1958)
    Phosphoric acid has been found to be an excellent source of phosphorus when used in beef cattle rations. Urea, a non-protein-nitrogen compound, has long been recognized as a satisfactory source of protein equivalent for ...
  • Richardson, D.; Mackintosh, D.L.; Merkel, R.A. (Kansas Agricultural Experiment Station, 1958)
    The details of management and feeding of animals involved in this test are given in part I of this report. Five wholesale rib cuts from each lot were obtained at the time of slaughter for cooking, palatability, mechanical ...
