  • Simms, D.D.; Goehring, T.B.; Lee, R.W.; Brandt, Robert T., Jr.; Laudert, S.B.; Kuhl, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Over 500 crossbred steers were used in three trials to compare lifetime implant strategies and to study the effects of implanting during the suckling period on performance in the growing and finishing periods. Contrary ...
  • Riley, Jack G.; Cochran, B.; Pope, Ronald V. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Rumensin® Ruminal Delivery Devices put in place 76 days prior to steers entering a feedlot resulted in an average reduction in daily dry matter intake of 3.6% and a small 1.8% increase in daily gain during a controlled ...
  • Johnson, R.D.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Implanting young bulls and steers with trenbolone acetate and zeranol (Ralgro ®) resulted in increased slaughter weights and carcasses that tended to have more marbling than those of control bulls. Furthermore, steaks ...
  • Riley, Jack G.; Pope, Ronald V.; O'Neill, L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Three levels of melengestrol acetate (30, 60, and 90 mg) injected subcutaneously as a liquid (DEPO-MGA ®) in the ear of heifers yielded high performance results comparable to feeding 0.5 mg of MGA per head daily. ...
  • Boyd, G.; Corah, L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Results from two trials showed that serving capacity (SC) can be successfully evaluated in yearling beef bulls under field conditions and is influenced by sire line (P<.01). Also, providing sexual experience to low ...
  • Cochran, R.C.; Riley, Jack G.; Owensby, Clenton E.; Towne, G.; Vanzant, E.S.; Pope, Ronald V. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Stocking rate in an intensive-early stocking system (1.25, 1.50, or 1.76 acres per steer) did not influence steer gains. Available forage on loamy upland sites was lower after steer removal on July 15 for the highest ...
  • Goehring, T.; Corah, L.; Higgins, James J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    A statistical analysis was used to determine which live animal traits are useful in predicting reproductive performance in first-calf heifers. Heifer condition score at calving and change in condition score postcalving, ...
  • Gross, K.L.; Harmon, D.L.; Avery, T.B. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Steers fed diets based on dry-rolled wheat or sorghum grain alone or combined (50:50) showed no differences in net portal fluxes of glucose, L-lactate, ammonia, urea, or alpha-amino nitrogen. Portal blood flow was increased ...
  • Laudert, S.B.; Kuhl, G.L.; Edwards, A.J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    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 ...
  • Laudert, S.B.; Kuhl, G.L.; Edwards, A.J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Heifers that were flank-spayed plus rumen-ovarian autografted (FS+A) responded similarly to Ralgro®, Synovex-H®, and Synovex-S® implants on' pasture. Grazing heifers spayed by the Kimberling-Rupp technique also responded ...
  • Harmon, D.L.; Gross, K.L.; Avery, T.B. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Feeding the ionophores monensin and lasalocid In a high-concentrate diet resulted in gut tissues utilizing less glucose. Monensin caused less urea to be recycled. The new, experimental ionophore (lCI 139603) resulted in ...
  • Bock, B.J.; Brandt, Robert T., Jr.; Harmon, D.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Dry rolled wheat and high moisture corn were fed singly and in three combinations in a 132-day finishing trial. Daily gain, feed intake, and final live weight were greatest on the 75% corn:25% wheat diet. Feed efficiencies ...
  • Corah, L.; Cochran, B.; Harmon, D.; Goehring, T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Adding rumen bypass fat to a range supplement reproductive characteristics, cow weight and condition performance during a 43-day postpartum feeding period.
  • Vanzant, E.S.; Beharka, A.A.; Cochran, R.C.; Avery, T.B.; Jacques, K.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Supplementing beef steers consuming immature bluestem with 0, 1, 2, or 4 lbs of sorghum grain daily did not affect forage intake. Thus, total intake increased as level of grain increased. Total dry matter, cell wall, and ...
  • Goll, S.J.; Kastner, Curtis L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    The dried weight of the material washed from meat surfaces by distilled water closely paralleled the binding strength between meat particles as measured by tensile strength testing. Sponges added to meat pieces during ...
  • Anderson, S.; Brandt, Robert T., Jr. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    A 60-day growth trial with 170 exotic crossbred steers (avg. wt. 626 lbs) was conducted to assess the value of raw soybeans in silage-based diets. Protein supplements were based on 1) urea, 2) urea plus soybean oil (SBO), ...
  • Patterson, D.J.; Corah, L.R.; Brethour, J.R.; Negus, W.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Records of age at puberty (AAP) and postpartum interval to estrus (PPI) for heifers calving first at 2 years of age were used to determine the relationship between the two reproductive parameters. In Brahman x Hereford ...
  • Kirch, B.; Hamma, S.; Bolsen, K.; Ilg, H.; Hoover, J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Four trials were conducted to determine the feeding value of whole-plant forage and grain sorghum silages. In general, growing cattle fed grain sorghum hybrids (NK2778, Funk's 550, DeKalb 42Y, DeKalb E67) out performed ...
