  • Gottlob, R.O.; Hastad, C.W.; Lawrence, K.R.; Knabe, D.A.; DeRouchey, Joel M.; Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Two experiments were conducted to determine the apparent and true-ileal amino acid digestibility, and to determine the digestible energy and metabolizable energy values of rice protein concentrate, salmon protein ...
  • Gottlob, R.O.; Hastad, C.W.; Groesbeck, C.N.; Lawrence, K.R.; DeRouchey, Joel M.; Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    A total of 168 weanling pigs (initially 13.8 lb and 21 ± 3 d of age, PIC) were used to determine the effects of different feed-grade antibiotics on nursery-pig performance. Pigs were fed one of four experimental diets: ...
  • Lenehan, N.A.; Frantz, N.Z.; Groesbeck, C.N.; Lawrence, K.R.; Goodband, Robert D.; Tokach, Michael D.; DeRouchey, Joel M.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Two hundred and forty barrows and gilts (initially 13.0 lb and 18 ± 2 d of age at weaning) were blocked by initial weight and were allotted randomly to one of five dietary treatments. There were eight replications (pens) ...

    A total of 156 finishing pigs (72 barrows and 84 gilts, initially 110 lb) were used to determine the effects on growth performance of increasing meat and bone meal. Pigs were housed in an environmentally regulated finishing ...
  • Lawrence, K.R.; Goesbeck, C.N.; Neill, C.R.; Goodband, Robert D.; Tokach, Michael D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    The objective of this study was to characterize the growth response to total sulfur amino acids (TSAA) and lysine simultaneously to estimate the true-ileal-digestible (TID) TSAA-to-lysine ratio in early finishing pigs. One ...
  • Neill, C.R.; Tokach, Michael D.; DeRouchey, Joel M.; Minton, J. Ernest; Groesbeck, C.N.; Lawrence, K.R.; Hastad, C.W.; Gottlob, R.O.; Hildabrand, B.M.; Burkey, T.E.; Nelssen, Jim L.; Goodband, Robert D.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    An experiment was conducted to evaluate the effects of weaning time (PM or AM) on nursery-pig growth performance. The objective was to see how weanling pigs would adjust to the nursery environment if sows were removed from ...

    A total of 224 nursery pigs (PIC L 327L × C22) initially 12.9 ± 3.0 lb and 21 d of age were used in a 28-d feeding trial. The objective of our study was to evaluate the effects of oregano oil, with or without an in-feed ...
  • Groesbeck, C.N.; Lawrence, K.R.; Valdez, F.; Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    A total of 150 pigs (PIC, initial body weight 178.9 ± 14.7 lb) were used in a 35-d study to evaluate the effect of chromium propionate and chromium tripicolinate on plasma non-esterifed fatty acids (NEFA) in growing-finishing ...
  • Groesbeck, C.N.; James, B.W.; Keegan, T.P.; Lawrence, K.R.; 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, 2004)
    Two experiments were conducted to evaluate the interactive effects between added pantothenic acid and ractopamine HCl (Paylean®) on growth performance and carcass traits of growing-finishing pigs. In Exp. 1, 156 pigs (PIC, ...
