  • Dikeman, Michael E.; Nagele, K.N.; Myers, S.M.; Schalles, R.R.; Kropf, Donald H.; Kastner, Curtis L.; Russo, F.A. (American Society of Animal Science, 2008-06-02)
    Twenty-four 8-mo-old Angus X Hereford (A X H) reciprocal crossbred steers and 28 3/8 Simmental X 1/4 Chianina X 3/8 Angus or Hereford steers (S X C) were utilized to study two production systems and two carcass-processing ...
  • Andries, K.M.; Schalles, R.R.; Franke, D.E.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-10)
    Carcass data from 5 years of a long-term, rotational , crossbreeding project were used to calculate heritabilities, genetic and phenotypic correlations , and management effects and to compare breeds for marbling, ribeye ...
  • Hickok, D.T.; Schalles, R.R.; Franke, D.E.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-20)
    Eighty nine steers with different proportions of Angus, Hereford, Charolais, Brahman, and Gelbvieh breeding from rotational and terminal crossbreeding systems were produced in Louisiana and finished at KSU. Half of ...
  • Schalles, R.R.; Bolsen, K.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station, 2010-12-15)
    No differences were found in total feed energy required to produce a pound of retail cuts between breeds or management systems. However, across breeds, faster gaining steers were more efficient. When yardage, facilities, ...
  • Hickok, D.T.; Schalles, R.R.; Franke, D.E.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-14)
    Data from the 207 crossbred steers used in this study indicate that when calves are placed in the feedlot on a finishing ration at weaning, they will have better feed efficiencies, greater lifetime ADGs, lighter carcass ...
  • Hickok, D.T.; Schalles, R.R.; Franke, D.E.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-15)
    Feedlot performance of 207 steers with various percentages of Angus, Hereford, Charolais, Brahman, and Gelbvieh breeding were compared at a constant 1) days fed, 2) adjusted carcass backfat, and 3) slaughter weight. ...
  • Andries, K.M.; Schalles, R.R.; Franke, D.E.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-03)
    Data from 5 years of a long-term, rotational crossbreeding project were used to compare breeds for growth and carcass traits. The traits of interest were direct and maternal birth and weaning weights, gain on feed, ...
  • Andries, K.M.; Schalles, R.R.; Franke, D.E.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-03)
    Data from 5 years of a long-term, rotational, crossbreeding project were used to calculate heritabilities and correlations and to make breed comparisons for growth rate and carcass traits in two different postweaning ...
  • Andries, K.M.; Schalles, R.R.; Franke, D.E.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-03)
    Growth and carcass data from 5 years of a long-term, rotational, crossbreeding project were used to calculate heritabilities and genetic and phenotypic correlations for direct and maternal birth and weaning weight, ...
  • Johnson, M.Z.; Schalles, R.R.; Olson, W.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-15)
    Heritabilities and genetic correlations for ultrasound-measured ribeye area and fat thickness, as well as growth traits and scrotal circumference, were determined using performance records of 1613 Brangus calves ...
  • Schalles, R.R.; Zoellner, K.O.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-06)
    Fast-growth genotype steers placed on a high energy ration a month after weaning were compared to a slow-growth genotype on a growing ration for 155 days, followed by a finishing ration for 62 days. The fast-growth ...
  • Andries, K.M.; Schalles, R.R.; Franke, D.E.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-05)
    The effects of primary color (black, red, or white) on performance and carcass characteristics of 253 cross-bred calves were evaluated. The only effect of color was that white calves had lighter birth weights than ...
  • Schalles, R.R.; Glaze, J.B.; Mallen-Spinzi, R.; Andries, K.M.; Rost, C.J.; Johnson, M.Z.; Olson, W.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-05)
    Ultrasound-measured ribeye area (REA) expected progeny differences (EPD) were calculated for 2974 Brangus cattle. Carcass data were collected from 168 steer progeny sired by eight bulls with ultrasound-measured ribeye ...
  • 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, 2010-10-15)
    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 ...
