  • Formation and safety of 2-dodecylcyclobutanone, a unique radiolytic product in irradiated beef
    Gadgil, P.; Smith, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Treating food with ionizing radiation improves product safety and helps maintain quality. The main selling point of irradiated foods is that it is microbially safe. Beginning in October 2002, companies could petition the ...
  • GnRH removal in the 7-11 CO-Synch for timed insemination of beef heifers
    Eborn, D.R.; Grieger, D.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    The use of artificial insemination can improve genetics, shorten the calving season, and increase weaning weights by having more calves born earlier in the breeding season. Reasons that this technology has not been used ...
  • Grain processing reduces E. coli O157 in feedlot cattle
    Fox, J.T.; Drouillard, J.S.; Jacob, M.E.; Reinstein, S.L.; Nagaraja, T.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Escherichia coli O157 is an important food-borne pathogen for which the gastrointestinal tract of cattle is the major reservoir. Fecal shedding of E. coli O157 in cattle reflects the ability of the organism to persist in ...
  • Limit-feeding a high-concentrate diet may alter nutrient absorption
    Wallace, J.O.; Miller, W.F.; Johnson, B.J.; Reinhardt, C.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Feeding newly arrived cattle is commonly characterized by a few days of feeding longstemmed hay followed by a series of step-up diets, wherein concentrate levels are increased to promote ruminal adaptation to a highconcentrate ...
  • Mature open cows are rarely persistently infected with bovine viral diarrhea virus
    White, B.J.; Larson, R.L.; Thomson, D.U. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Bovine viral diarrhea virus (BVDv) is an immunosuppressive virus affecting cattle in a multitude of ways. The varied presentation makes this disease difficult to identify in cow herds and the signs of a BVD infection ...
  • Microbial use of recycled urea is dependent on the level and frequency of degradable intake protein supplementation
    Wickersham, T.A.; Titgemeyer, E.C.; Cochran, R.C.; Wickersham, E.E.; Moore, E.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Protein supplementation increases utilization (intake and digestion) of low-quality forage and ultimately animal performance. Despite its effectiveness, protein supplementation is often expensive. One strategy to reduce ...
