  • Pollman, D.S.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    A total of 116 sows were used in a study to evaluate the effect of penicillin or long-acting oxytetracycline on reproductive performance. Antibiotic injection at breeding time did not improve farrowing rate or litter size. ...
  • Ohh, S.J.; Allee, G.L.; Behnke, Keith C.; Deyoe, C.W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    A 2 x 2 x 2 factorial experiment was conducted to evaluate the effects of two grain sources (corn or sorghum grain), two processing methods (hammer mill or roller mill), and two particle sizes (fine and coarse) on performance ...
  • Wheat, J.D.; Suba, M.S.; Dayton, A.D.; Allee, G.L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    The average for 1813 farrowing intervals was 16.78 minutes with a standard deviation of 25.37 minutes. Farrowing duration averaged 141.51 minutes, ranging from 11 to 618 minutes. The difference between farrowing intervals ...
  • Stevenson, Jeffrey S.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Our objective was to characterize reproductive performance for sows nursed by only two to four pigs for the last 5 days of lactation. Litter size was reduced beginning at 2 (16 sows), 3 (15 sows), or 4 (15 sows) weeks after ...
