  • Nichols, David A.; Murphy, James P.; Vic Robbins, F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Twenty eight sows and gilts were used to evaluate the value of drip sprinkling to reduce heat stress in lactating sows. Respiration rates for sprinkled sows were significantly lower than those of controls. Daily feed intake ...
  • Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Three trials involving 61 litters of pigs were conducted to evaluate the effects of creep feeding and creep diet on weaning weight and subsequent performance in the nursery. Pigs offered a commercial milk replacer pellet ...
  • Kluber, E.F. III; Pollmann, D.S.; Blecha, Frank (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Two trials were conducted with a total of 112 artificially reared pigs to evaluate the effect feeding Streptococcus faecium. The areas studied were growth and feed efficiency, mortality rate, daily scour score, blood ...
  • Jensen, M.A.; Blecha, Frank; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Housing pigs in a thermal stress environment reduced gain, intake and feed efficiency. Cell mediated immunity responses were lower under the constant heat stress as well as when the temperature was lowered to a thermal ...
  • 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 ...
  • Blecha, Frank; Pollmann, D.S.; Nichols, David A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Pigs weaned at 3 weeks of age and regrouped with unfamiliar individuals had a 4-fold increase in plasma cortisol when compared to pigs that remained in a litter group. However, cellular measures of immune function were not ...
  • Keeler, G.L.; Pollmann, D.S.; Blecha, Frank; Broce, A.B.; Wooten, E.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Twenty -eight pigs were used to evaluate the effect the sarcoptic mange mite infestation on growth and immunity of growing-finishing pigs. Although mange mite infestation did not affect gain, the white blood cell counts ...
  • Davis, Duane L.; Stevenson, Jeffrey S.; Schmidt, W.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Gilts were artificially inseminated on the fifth, sixth and seventh days after estrous synchronization with altrenogest (scheduled AI). Contemporary controls also were synchronized but were checked for estrus twice daily. ...
  • 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 ...
  • Pollmann, D.S.; Allee, G.L.; Schoenherr, W.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Two on-farm trials with a total of 264 sows were conducted to evaluate the effects of added fat in the diet during the last seven days of lactation and/or during the period from weaning to remating on days from weaning to ...
  • Schmidt, W.E.; Davis, Duane L.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    We penned sows after weaning either in groups of 4 or 5 or individually in gestation stalls. Beginning 3 days after weaning sows were checked twice daily and artificially inseminated 24 and 36 hr after first detected ...
  • Stevenson, Jeffrey S.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Our objective was to determine the effectiveness of inducing estrus during lactation by reducing the nursing load of the sow between 2 and 4 weeks after farrowing. lactating sows were separated from their litters for ...
  • Pollmann, D.S.; Dennis, S.M.; LaForge, R.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Twenty-four sows were utilized to evaluate the influence of a high fiber diet on nutrient digestibility and hindgut bacterial populations and volatile fatty acid (VFA) concentrations. Sows were fed either a control of ...
  • Vargas Vargas, J.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Three feeding trials using 480 finishing pigs were conducted to evaluate meal time feeding versus ad libitum feeding. Growth rate and feed required per pound of gain were similar for all treatments. Carcass characteristics, ...
  • Schoenherr, W.D.; Pollmann, D.S.; Kennedy, G.E.; Schoneweis, D.A.; LaForge, R.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Three experiments were conducted with pigs to examine the influence of two antimicrobial agents on growth, blood parameters, the intestinal flora population and the therapeutic action on mycoplasma pneumonia. The pigs were ...
  • Erickson, Howard H.; Faraci, F.M.; Olsen, S.C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Pigs were exercised for 5 minutes at five different treadmill speeds (1.0-1.8 m• sec^-1 ) (3° incline), while oxygen consumption (MO2), carbon dioxide production (MCO2), and the electrocardiogram (ECG) were continuously ...
  • Hsu, A; Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    A rapid in vitro method has been developed to predict digestibilities of nitrogen, dry matter (DM) and energy in feed ingredients and mixed diets for swine. A total of 21 samples, including nine feed ingredients and 12 ...
  • Hsu, Ali; Allee, G.L.; Pollmann, D.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Nine individual feed ingredients and 12 mixed diets were used in an attempt to select the most suitable regression equation for predicting energy value and nitrogen digestibility from chemical analyses. Samples were analyzed ...
