  • Stevenson, Jeffrey S.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-30)
    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 ...
  • Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07)
    During the breeding period, adding the fermentation product (lactobacillus acidophilus) to the ration fed to gilts and sows made no difference in conception percentages. Nonsignificant differences was observed between the ...
  • Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07)
    Post-weaning comparisons were made using high and low protein rations with and without a fermentation product (lactobacillus acidophilus). Pigs receiving higher protein rations (18%) grew slightly faster than those receiving ...
  • Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-30)
    Two feeding trials involving a total of 320 head of finishing pigs were used to evaluate the effect of feeding an antibiotic to three groups selected from within a farrowing group. Pigs were divided by weight into group A ...
  • Rosenkrans, C.F.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-15)
    Mixtures of vitamins and amino acids produced detrimental effects on the development of pig embryos. However, addition of three amino acids, phenylalanine, methionine, and isoleuncine, enhanced pig embryo development.
  • Allee, G.L.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07)
    Gestating Yorkshire sows and gilts were randomly assigned to two dietary treatments immediately after a 25-day breeding season until females were brought to the farrowing house between 105-110th day of gestation. Sows and ...
  • Linneen, S.K.; Benz, J.M.; DeRouchey, Joel M.; Goodband, Robert D.; Tokach, Michael D.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009-10-20)
    Oxytocin is frequently used to decrease farrowing time and birth interval as an aid to prevent stillbirths, but recent research has shown that oxytocin use can increase the number of pigs stillborn when used too early in ...
  • Kim, I.H.; Kang, M.S.; Hines, Robert H.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-03-26)
    Eight crossbred barrows (initial body wt of 90 lb and 180 lb for four growing and four finishing pigs, respectively) were fitted with T-cannulas at the distal ileum and used in 36-d metabolism experiments (4 x 4 Latin squares) ...
  • Kim, I.H.; Gugle, Terry L.; Hines, Robert H.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-03-26)
    Ninety nursery pigs were used in two metabolism experiments to determine the effects of roasting and extruding on the nutritional value of Williams 82 soybeans with (+K) and without (-K) gene expression for the Kunitz ...
  • Harner, Joseph P.; Murphy, James P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-08)
    A recent water quality survey assessment found nonpoint source pollution problems in a majority of Kansas surface waters - 85% of the monitoring sites were impaired by nutrients, 60% of the sites by bacteria, 55% by ...
  • Koch, B.A.; Allee, G.L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07)
    Two feeding trials involving 118 finishing Pigs were conducted to determine minimum salt needed in finishing diets. Performance of pigs fed 0.2 to 0.5% salt diets did not differ significantly, but pigs fed 0.1% or no ...
  • Davis, Duane L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07)
    Scrotal measurements and visual scores of testicle size were determined for 59 boars used in nutrition and physiology studies. The best predictors of testicular weight were visual scores (average of 3 observers) and ...
  • Wheat, J.D.; Kropf, Donald H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07)
    Litters farrowed total 147 (25 in 1971, 23 in 1972, 33 in 1973, 32 in 1974 and 34 in 1975); pigs total 1196, 1102 alive at birth 94 (8%) dead at birth. Line differences in loin eye area, backfat thickness and age (adjusted ...
  • Healy, B.J.; Bramel-Cox, P.J.; Richert, B.T.; Klopfenstein, C.F.; Witt, Merle D.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-02)
    Six cannulated barrows and two hundred eighty-eight chicks were used in an experiment to determine the value of an in vitro protein digestibility assay (pepsin digest) for identification of sorghum parent Iines with ...

    Six cannulated barrows and two hundred eighty-eight chicks were used in an experiment to determine the value of an in vitro protein digestibility assay (pepsin digest) for identification of sorghum parent lines with ...
  • Wheat, J.D.; Kropf, Donald H.; Na-Lampang, P.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-06)
    Select line pigs were compared with those in the control line for growth patterns, production traits, and carcass quality. Heritability and genetic correlations were calculated for certain production and carcass traits ...
  • Wheat, J.D.; Kropf, Donald H.; Chang, C.H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07)
    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 ...
  • Duttlinger, A.W.; Houser, Terry A.; Tokach, Michael D.; Dritz, Steven S.; Prusa, K.J.; Huskey, L.; DeRouchey, Joel M.; Nelssen, Jim L.; Goodband, Robert D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009-11-12)
    Sensory characteristics were evaluated on a total of 80 loins from pigs fed diets containing glycerol, ractopamine HCl (RAC), and a combination of glycerol and RAC during the last 28 d prior to harvest. A total of 1,054 ...
  • Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-22)
