  • Mark, D.R.; Boland, Michael A.; Fox, J.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Pork producers in Kansas were surveyed to determine their attitudes regarding onfarm Salmonella testing and to provide estimates ofthe costs ofcollecting hide, fecal, or blood samples from live pigs. Veterinarians and ...
  • Rettmer, I.; Stevenson, Jeffrey S.; Goodband, Robert D.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Primiparous and multiparous sows received a single dietary supplement of L-tyrosine in their feed on the day after weaning, and the effects on various reproductive traits were evaluated. Sows received either none (control; ...
  • Koons, L.; Riley, Jack G. (Kansas State University. Agricultural Experiment Station, 1977)
    Twenty-four Kansas feedyards with 432,000 head capacity participated in a survey on operation procedures. The survey covered five areas: processing, animal health, rations, facilities, and marketing. Methods differed most ...
  • Smith, J.F.; Harner, Joseph P.; Bradford, Barry J.; Overton, M.W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    Low profile cross ventilated freestall buildings are one option for dairy cattle housing. These facilities allow producers to control the cows’ environment during all seasons of the year. As a result, an environment ...
  • Walker, Charles E.; Drouillard, James S.; Nagaraja, T. G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
