  • Pretzer, D.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    This study examined the economic effects of applying controllable management factors for farrow-to-finish operations. Average producers in Kansas market 7 pigs/litter with an average feed conversion of 4.58. Improvement ...
  • Wheat, J.D.; Suba, M.S.; Allee, G.L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Average farrowing interval and duration were 15.8 and 143.8 minutes for 1766 pigs born in 169 litters. Pigs born later in the litter were larger (r=.43) at birth. The correlation was -.14 between farrowing interval, average ...
  • Tonn, S.T.; Craig, J.V.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    We compared mating performance and soundness of feet and legs of boars which were reared in group vs individual pens. Individually penned boars consumed more feed from 6 to 12 weeks of age and were heavier at 12 weeks of ...
  • Blecha, Frank; Pollmann, D.S.; Nichols, David A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    The stress of weaning lowers cellular immune reactivity in 2-, 3- and 4-week-old pigs. However, pigs weaned at 5 weeks of age do not exhibit altered cell-mediated immune reactivity. Those changes could alter disease ...
  • Pollmann, D.S.; Smith, J.E.; Stevenson, Jeffrey S.; Schoneweis, D.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Gleptosil, a commercial iron product, was compared with iron dextran for the prevention of iron deficiency anemia in young pigs. Using 26 litters, pigs (within each litter) were randomly allotted to one of the three ...
  • George, H.C.; Spillman, C.K.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Accurate and concise heat loss analysis is available through a computer program to help producers. The economic benefit of insulating a new structure or increasing the insulation level of each of the building parts (ceiling, ...
  • Davis, Duane L.; Scmidt, W.E.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Injecting gilts with 10 cc’s combiotic at artificial insemination did not improve farrowing rate or litter size.
  • Henry, S.C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Among the many changes in the swine industry during the past two decades, the concept of "Herd Health Programs" came to be. Still a buzz word with poorly defined activities, "Herd Health Programs" are part of our industry. ...
  • Nuzback, L.J.; Pollmann, D.S.; Behnke, Keith C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Sixteen pregnant crossbred sows (second parity) were employed in a digestion trial to evaluate the effect of particle size and physical form of sun-cured alfalfa. The treatment consisted of 1/4 inch meal, 1/4 inch pelleted, ...
  • Pollmann, D.S.; Koch, B.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Two studies using a total of 64 starter pigs (averaging 16-18 lbs initial weight) to evaluate the influence of varying levels of vornitoxin-contaminated wheat on performance was conducted. In both trials it appears that ...
  • Pollmann, D.S.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Ninety crossbred pigs averaging 135 lbs. were used to evaluate the effect of reduced bushel weight of wheat on performance. Wheat (59 lb) fed to finishing pigs resulted in growth and feed efficiency similar to a milo base ...
  • Zook, W.; Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Two feeding trials with 138 crossbred pigs with an average initial weight of 129 pounds were conducted to determine the effects of limit feeding on average daily gain, feed efficiency and carcass measurements. Pigs were ...
  • Pope, S.; Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Three trials were conducted utilizing 458 pigs with an average age of 21 days to study the effects of adding whole whey, or partially delactosed whey from two sources in the diet of weaned pigs on growth, feed intake, and ...
  • Nichols, David A.; Pollmann, D.S.; Olson, W.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Records of approximately 11,000 boars and 6,000 gilts enrolled in the KSU on-farm swine test program were summarized. Both boars and gilts reached 220 lbs 5 days sooner in 1980 than 1970. Of the traits evaluated, the largest ...
  • Pollmann, D.S.; Simms, D.; Francis, E.; Orwig, T.; Brazle, F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Twelve on-farm trials with a total of 1572 pigs were conducted to evaluate the effect of Flavomycin in growing-finishing swine diets. In three of the twelve trials, average daily gain was increased (P<.06) and in seven of ...
  • Schmidt, W.E.; Davis, Duane L.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    KSU breeding records show a higher farrowing rate for gilts that "lock" on the insemination spirette at both inseminations as opposed to gilts that "lock" at one insemination or at neither insemination. Continued research ...
  • Greig, J.K.; Spillman, C.K.; Koch, B.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Exhaust air from a Kansas State University swine-farrowing house provides CO2 and possibly other gases that are being used by vegetable plants in a KSU greenhouse. In addition, a rock-storage system reduces fuel requirements ...
  • Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Three feeding trials were conducted to compare soft winter wheat with hard winter wheat for finishing swine. In each trial, soft wheat diets supported weight gains and feed/gain ratio equal to those observed for pigs fed ...
  • Pollmann, D.S.; Kennedy, G.A.; Koch, B.A.; Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Two trials were conducted to determine the influence of non viable lactobacillus fermentation product (LFP) in artificially reared pigs removed from sows at 24 to 36 hours postpartum. The pigs were fed a non-medicated milk ...
  • Stevenson, Jeffrey S.; Pollmann, D.S.; Davis, Duane L.; Murphy, James P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    A study involving 327 crossbred sows was conducted to determine whether providing supplemental light in farrowing rooms would influence litter weight, number of pigs weaned, piglet survival rate, and subsequent rebreeding ...
