  • Stanley, T.A.; Cochran, R.C.; Harmon, D.L.; Vanzant, E.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Four, ruminally cannulated, Hereford × Angus cows were used to study factors associated with feed intake patterns around parturition. Feed intake during the final trimester of gestation was relatively stable, in spite ...
  • Garcia-Lagombra, G.; Harbers, L.H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Corn grain samples collected over several years were used to develop equations for dry matter, crude protein, crude fiber, and ether extract (crude fat). Two computer models were used to select samples having a range ...
  • Rettmer, I.; Corah, L.R.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Pregnancy rates were assessed in suckled beef cows (n=145) and virgin beef heifers (n=606) of mixed breeding following an injection of either 100 or 200 μg of a GnRH agonist given once on d 11-14 after estrus ...
  • Dickerson, J.T.; Niwa, Y.; Bolsen, K.K.; Brent, B.E.; Lin, C.; Bradford, J.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Effects of covering, time, and depth from the surface on the rate and extent of top spoilage losses in alfalfa silages stored in horizontal silos were studied under pilot- and farm-scale conditions. Covering silages ...
  • 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 ...
  • Blasi, Dale A.; Fjell, Dale L.; Shroyer, James P.; Kuhl, G.L.; Heer, William F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Six, summer annual forages and three forage sorghums were evaluated for forage yield and quality under south central Kansas dryland conditions. The sudans and forage sorghums produced similar amounts of dry matter ...
  • Beck, T.J.; Simms, D.D.; Brandt, Robert T., Jr.; Cochran, R.C.; Kuhl, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    During two winters, 96 beef cows in late gestation were utilized in 60-day precalving feeding trials to evaluate supplementation for cows fed ammoniated wheat straw. Treatments included: control--mineral supplement ...
  • Huck, G.L.; Brandt, Robert T., Jr.; Simms, D.D.; Kuhl, G.L.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Angus and Angus-cross calves (632 lb) were utilized in a finishing study to evaluate the effects of implanting with estradiol and progesterone (Synovex-S®) and(or) trenbolone acetate (Finaplix®) on performance of ...
  • Dickerson, J.T.; Ashbell, G.; Pfaff, L.; Bolsen, K.K.; Brent, B.E.; Bradford, J.E.; Smith, R.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    The top 3 feet from 30 horizontal silos was sampled at three depths to determine top spoilage losses, using ash content as an internal marker. When compared to face samples, corn and forage sorghum silages exhibited ...
  • Garcia-Lagombra, G.; Harbers, L.H.; Velazco, J.; Morrill, J.L.; Maziya, B.B.; Harbers, C.A.Z. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Near-infrared reflectance spectroscopy (NIRS) offers the potential for rapid, low-cost analyses of meat samples. Beef and pork samples were analyzed by both standard laboratory (AOAC) methods and NIRS. Regression ...
  • Waldner, D.N.; Schalles, R.R.; Olson, W.; Houghton, P.; Corah, L.R.; Dikeman, Michael E.; Unruh, John A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Sixty Brangus bulls were evaluated live with two real-time ultrasound instruments to estimate ribeye area (REA) and 12th rib fat thickness (FT) every 4 mo beginning at 4 mo and 12 mo of age, respectively, and continuing ...
