  • Young, M.G.; Aherne, F.X.; Main, R.G.; Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    A total of 684 sows from breeding groups over six weeks were used to compare three methods of feeding during gestation and to assess the subsequent effects on lactation performance. Control gilts and sows were fed according ...
  • Kim, I.H.; Hines, Robert H.; Burnham, L.L.; Gugle, Terry L.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1995)
    In a 3 I-d nursery experiment, replacing soybean meal (SBM) with dry-extruded whole soybeans (DEWS) tended to improve F/G (6% overall difference), but ADG was not affected. Adjusting the diet with DEWS to the nutrient:calorie ...
  • Brown, K.R.; Johnson, B.J.; Frantz, N.Z.; Gottlob, R.O.; Groesbeck, C.N.; Hastad, C.W.; Neill, C.R.; Schneider, J.D.; Young, M.G.; Woodworth, J.C.; Goodband, Robert D.; Tokach, Michael D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2005)
    A total of 59 gilts were used to determine the effects of supplemental L-carnitine on gilt growth and maternal insulin-like growth factor- I (IGF-I). Experimental treatments were arranged in a 2 × 3 factorial with main ...
  • Friesen, K.G.; Weeden, T.L.; Richert, B.T.; Kats, L.J.; Nelssen, Jim L.; Goodband, Robert D.; Tokach, Michael D.; Unruh, John A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1992)
    One hundred and twenty pigs (initially 96 lb BW) were slaughtered either at 230 lb (40 pigs) or at 280 lb (80 pigs) to determine the interrelationship between genotype, sex, and dietary lysine effect on carcass ...
  • 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 ...
  • Wheat, J.D.; Kropf, Donald H.; Chang, C.H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1974)
    Line differences in weight, litter size at different ages, and in age, loin eye area, and backfat thickness of pigs (adjusted to 200 pounds live weight) were not significant. Sex differences in weight and backfat thickness ...
  • Koch, B.A. (Kansas Agricultural Experiment Station, 1963)
    Vitamin A supplementation recommendations vary considerably from station to station. Most research indicates that supplementation recommendations are generally much higher than actually necessary. This study was designed ...
