    With the emergence of Bovine spongiform encephalopathy (BSE) and the necessity to guarantee cattle ages to meet export requirements of some countries, the need to accurately determine age is paramount to the worldwide ...
  • 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 ...
