  • Microbial evaluation of steam pasteurization and comparison of excision versus sponge sampling recovery
    Retzlaff, D.L.; Rueger, S.A.; Phebus, Randall K.; Marsden, James L.; Kastner, Curtis L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    The use of steam pasteurization (SPS400™; Frigoscandia, Bellevue, WA) as a viable commercial-scale intervention method to treat pre-rigor beef carcasses uniformly hasbeen evaluated for temperatures from 180E to 201 ̊F. ...
  • Microbial shelf life of chub-packaged ground beef from four large U.S. processing plants
    Peters, P.E.; Gamage, S.D.; Luchansky, J.B.; Phebus, Randall K. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Ten pound chubs of coarsely ground beef of two different lean:fat specifications (73:27 and 81:19) were stored at three temperatures (34, 38 or 45 ̊F) to monitor the effects of storage temperature on microbial condition ...
  • Milking two or five times daily in the presence of a cow’s own nonsuckling calf fails to prolong postpartum anovulation
    Lamb, G.C.; Thompson, K. E.; Heldt, J.S.; Löest, C.A.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Three treatments were initiated at approximately 15 days after calving and continued for 4 weeks: 1) cows were suckled ad libitum by their calves (calf present [CP]); 2) calves were present but nonsuckling 24 hr/day and ...
  • Molasses-fat blend as an energy source and conditioning agent in feedlot diets
    Flake, A.S.; Kuhl, G.L.; Drouillard, James S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Seventy-two yearling crossbred steers were used in an individual feeding trial to evaluate the effects of adding a molasses-fat blend (Synergy® 19/14; Cargill Molasses Liquid Products) to diets at 6 or 12% (dry ...
  • Predicting voluntary forage intake in cattle
    Bandyk, C.A.; Cochran, R.C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    A large database was compiled of forage intake observations published during the past 20 years. Inputs included a wide range of factors believed to be related to voluntary intake. An analysis was designed to pinpoint ...
  • Prevalence of Escherichia coli O157:H7 in cow-calf herds in Kansas
    Sargeant, J.M.; Gillespie, J.R.; Hyatt, D.R.; Galland, J.C.; Bohra, L.K.; Oberst, Richard D.; Phebus, Randall K.; Hays, Michael P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Fecal samples from cows and calves and samples of water sources were collected monthly for 8 months from 10 Kansas cow-calf farms to determine the prevalence of E. coli O157:H7. The bacterium was found in 8% of fecal ...
  • Prevalence, antibiotic susceptibility, and genetic diversity of Salmonella, Campylobacter, and Escherichia coli O157:H7 collected at four Kansas beef cattle feedyards over 13 months
    Hyatt, D.R.; Galland, J.C.; Crupper, S.; Hawkins, L.; Anderson, N.V.; Stokka, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Salmonella, Campylobacter, and Eschericia coli O157:H7 are important foodborne pathogens, but longitudinal studies of their prevalence in beef cattle feedyards have not been done. Our long- term study involved 24,556 ...
  • Price discovery issues for fed cattle
    Mintert, J.; Ward, C.E.; Peel, D.S.; Schroeder, Ted C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Interviews were conducted with cattle feeders, beef packers, and others involved in the beef industry to discern their concerns about fed-cattle price discovery. Three issues predominated. First was the need to better ...
  • Projecting fed cattle price discovery over the next decade
    Mintert, J.; Ward, C.E.; Peel, D.S.; Schroeder, Ted C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Interviews were conducted with cattle feeders, beef packers, and others involved in the beef industry to project how fed cattle prices will be discovered in the next decade. Respondents generally indicated that economics ...
  • Site of semen deposition and fertility in lactating beef cows synchronized with GnRH and PGF2a
    Lamb, G.C.; Thompson, K. E.; Anderson, K.; Grieger, David M.; Rozell, Timothy G.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Our objective was to determine the effect of site of semen deposition on pregnancy rate in beef cows inseminated at a fixed time or after observed estrus. Cows were synchronized with a combination of gonadotropin-releasing ...
  • Soybean hulls in roughage-free diets for limit-fed growing cattle
    Löest, C.A.; Bindel, D.J.; Titgemeyer, Evan C.; Drouillard, James S.; Blasi, Dale A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Three hundred heifers (573 lb initial body weight) were used in a growing study to compare growth performance of cattle fed roughage-free diets comprised mainly of soybean hulls with that of cattle receiving roughage- and ...
