    Weeden, T.L.; Nelssen, J.L.; Hansen, J.A.; Richardson, K.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    One hundred ninety-six pigs (21 d of age and 12.3 lb initial wt) were used to evaluate the effect of adding an organic acid blend (OAB) to starter diets on growth performance and nutrient digestibility. The four dietary ...
  • Effect of L-carnitine on starter pig performance and fat utilization
    Weeden, T.L.; Nelssen, J.L.; Hansen, J.A.; Fitzner, G.E.; Goodband, R.D.; Li, D.F.; Blum, S.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Three hundred early-weaned pigs with average initial weights of 12.3 and 13.2 lb, respectively, were utilized in two 5-wk experiments to determine the effect of L-carnitine on growth Performance. Diets contained 20% dried ...
  • Effect of substituting spray-dried plasma protein for milk products in starter pig diets
    Hansen, J.A.; Goodband, R.D.; Nelssen, J.L.; Friesen, K.G.; Weeden, T.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Two growth trials utilizing 444 weaned pigs were conducted to determine the efficacy of substituting spray-dried porcine plasma protein (PP) for dried skim milk (DSM) and/or dried whey (DW) in starter pig diets. Trial 1 ...
  • The effects of additional niacin during gestation and lactation on sow and litter performance
    Goodband, R.D.; Nelssen, J.L.; Weeden, T.L.; Li, D.F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    One hundred and twenty-one first-litter sows were utilized to evaluate the effects of additional niacin on sow and litter performance through two parities. The control diet provided sows with 50 mg/d niacin during gestation ...
  • Effects of daily administration of porcine somatotropin on performance of growing pigs (55 to 130 lb)
    Fitzner, G.E.; Hines, R.H.; Nelssen, J.L.; Kropf, D.H.; Weeden, T.L.; Goodband, R.D.; Hancock, J.D.; Healy, B.J.; Schricker, B.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Sixty crossbred barrows initially weighing 55.7 lb were used to evaluate six experimental treatments during a 5-wk growth trial. Pigs received one of three levels of dietary lysine (1.0, 1.5, or 2.0%) and were injected ...
  • The effects of dietary threonine and porcine somatotropin dosage on nitrogen balance in finishing swine
    Swanson, J.A.; Goodband, R.D.; Nelssen, J.L.; Schricker, B.R.; Li, D.F.; Hansen, J.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Fifteen crossbred barrows were utilized to determine the effects of porcine somatotropin (pST) administration in combination with increasing dietary threonine levels on nitrogen retention and growth performance. Barrows ...
  • Effects of porcine somatotropin and dietary lysine level on growth performance and carcass characteristics of finishing swine fed to 280 lb.
    Johnston, M.E.; Nelssen, J.L.; Goodband, R.D.; Kropf, D.H.; Hines, R.H.; Schricker, B.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    One hundred twenty barrows with an initial wt of 130 lb were utilized to determine the effects of dietary lysine level and porcine somatotropin (pST) injection on growth performance and carcass characteristics of finishing ...
