    A 21 d growth trial was conducted to evaluate the effects of increasing the apparent digestible tryptophan:lysine ratio on growth performance of the 25 to 50 lb pig raised in a high-health, segregated early-weaning (SEW) ...
  • Effect of dietary L-carnitine on growth, carcass characteristics, and metabolism of swine
    Owen, K.Q.; Ji, H.; Maxwell, C.V.; Nelssen, J.L; Goodband, R.D.; Tokach, M.D.; Tremblay, G.C.; Koo, S.I.; Blum, S.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1996)
    Thirty six Yorkshire gilts (initially 123 lb BW) were used to investigate the effect of dietary carnitine on growth performance, carcass characteristics, fatty acid oxidation, and enzyme kinetics. Dietary carnitine reduced ...
  • Effect of fat source and level on finishing pig performance
    Nichols, D.A.; Nelssen, J.L; Hancock, J.D.; Kropf, D.H.; Hines, R.H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Two hundred and forty finishing pigs were utilized to evaluate the effect of fat source and level on growing pig performance and carcass characteristics. Pigs were fed a milo-soybean meal diet balanced on a constant ...
  • Effects of copper sulfate, tri-basic copper chloride, and zinc oxide on weanling pig growth and plasma mineral concentrations
    Shelton, N.W.; Tokach, M.D.; Nelssen, J.L; Goodband, R.D.; Dritz, S.S.; DeRouchey, J.M.; Hill, G.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    Two 28-d experiments were conducted to determine the effects of increasing dietary zinc and copper levels on weanling pig performance. In each experiment, 180 weanling pigs (PIC, 21 d of age, 12.5 lb in Exp. 1 and 13.2 lb ...
  • Effects of increasing dietary dried distillers grains with solubles and glycerol on pork loin quality
    Gipe, A.N.; Houser, T.A.; Duttlinger, A.W.; Tokach, M.D.; Dritz, S.S.; DeRouchey, J.M.; Nelssen, J.L; Goodband, R.D.; Prusa, K.J.; Fedler, C.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    A total of 1,160 barrows (PIC, initially 68.4 lb) were used in a 70-d study to determine the influence of dried distillers grains with solubles (DDGS) and glycerol on pork loin quality attributes. The pigs were blocked by ...
  • The effects of two true-ileal-digestible lysine concentrations, Optipak®, ractopamine hcl (paylean®), and their combinations, on the growth performance and carcass characteristics of finishing pigs reared in commercial facility
    Bergstrom, J.R.; Tokach, M.D.; Dritz, S.S.; Nelssen, J.L; DeRouchey, J.M.; Goodband, R.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    A total of 1,207 pigs (PIC, 337 × 1050) were used in a 28-d experiment in a commercial research barn to evaluate the effects of two true ileal digestible (TID) lysine concentrations, Optipak®, ractopamine HCl, and their ...
  • The influence of dietary lysine on carcass characteristics and subprimal cut distribution of high-lean growth gilts fed to 230 and 300 lb
    Stuewe, S.R.; Unruh, J.A.; Friesen, K.G.; Nelssen, J.L; Goodband, R.D.; Tokach, M.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
