    Our data suggest that adding slightly rancid choice white grease with peroxide values of 40 mEq/kg and less and p-anisidine values of 10.6 and less to diets will not decrease growth performance in nursery pigs. However, reduced ...
  • Park, J.S.; Gugle, Terry L.; Jones, C.L.; Starkey, C.W.; Lee, D.J.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Two hundreds sixteen pigs were used to determine the effects of deleting vitamin and mineral premixes on growth performance, carcass characteristics, and integrity of vertebrae in finishing pigs housed in large groups ...
  • Jones, C.L.; Hancock, Joe D.; Behnke, Keith C.; Sowder, C.M.; McKinney, Leland J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    The sorghums used in our experiment (mill-run, red feed-quality, and white food-quality) had greater true grinding efficiency than corn. Mill-run sorghum also ground easier and with greater true efficiency than the red ...
  • Park, J.S.; Kropf, Donald H.; Hachmeister, K.A.; Hines, Robert H.; Jones, C.L.; Dean, D.W.; Lee, D.J.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    From 185 to 225 lb BW, no differences in ADG, ADFI, or F/G occurred among pigs fed diets without or with vitamin and trace mineral premixes. Then, from 225 to 266 lb BW, a special premix with megadoses of vitamin E, ...
  • Evans, E.I.; Stevenson, Jeffrey S.; Davis, Duane L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    We used 66 pregnant sows to compare serum progesterone concentrations following a single injection of either saline or one of two prostaglandin F2a products approved for use in swine. Pregnant sows in a commercial swine ...
  • Real, D.E.; Woodworth, J.C.; Webster, M.J.; Tokach, Michael D.; Nelssen, Jim L.; Goodband, Robert D.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    A 24-d growth study was conducted to evaluate the effects of low rates of a dietary acidifier, calcium propionate, on weanling pig growth performance. Experimental diets, fed from d 0 to 10, were a control diet with no ...
  • Real, D.E.; Woodworth, J.C.; Webster, M.J.; James, B.W.; Alonso, E.; Nelssen, Jim L.; Tokach, Michael D.; Goodband, Robert D.; Unruh, John A.; DeRouchey, Joel M.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    One hundred forty-four finishing pigs were used to determine the influence of added dietary niacin on their growth performance and meat quality. Gilts grew slower, ate less, and were more efficient than barrows for the ...
