  • Nutrient composition of Kansas swine lagoons and hoop barn manure
    DeRouchey, Joel M.; Nelssen, Jim L.; Tokach, Michael D.; Murphy, James P.; Goodband, Robert D.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    A total of 236 lagoon and 35 hoop barn manure samples were collected during 2000 from Kansas swine operations to determine the effects of production phase and season of the year on their nutrient concentration. Lagoon ...
  • The optimal ratio of apparent digestible valine to lysine to maximize growth performance of the nursery pig
    James, B.W.; Woodworth, J.C.; Goodband, Robert D.; Tokach, Michael D.; Nelssen, Jim L.; DeRouchey, Joel M.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    A total of 210 nursery pigs (initially 19.6 lb and approximately 28 d of age) were used in a 21-d growth assay to determine the optimal ratio of valine to lysine to maximize growth performance. The seven treatments consisted ...
  • The optimal threonine:lysine ratio to maximize growth performance of nursery pigs
    James, B.W.; Woodworth, J.C.; Goodband, Robert D.; Tokach, Michael D.; Nelssen, Jim L.; DeRouchey, Joel M.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    A total of 210 pigs (initially 18.2 lb and 25 d of age) were used in a 21-d growth assay. The seven treatments consisted of a basal diet (14.1% CP) with increasing levels of threonine (45, 50, 55, 60, 65, and 70% of 1.07% ...
  • The relationship between body condition score and backfat in gestating sows
    Young, M.G.; Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Backfat and body condition score were measured on 731 sows in a commercial swine facility to assess the accuracy of feeding sows in gestation based on body condition score. Body condition score was poorly correlated (r2 ...
  • Utilizing infrared thermography to predict pork quality
    Lawrence, T.E.; Spire, M.F.; Dikeman, Michael E.; Hunt, Melvin C.; Hogge, S.B.; James, B.W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Three experiments using 63 pigs were conducted to determine if infrared thermography could segregate pigs based on subsequent pork quality. Pigs were subjectively classified as either “hot” or “normal” based on infrared ...
