  • Kropf, Donald H.; Kasten, L.H.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    Many studies have reported that barrows gain more rapidly than gilts, but gilts excell in carcass muscling and trimness. Recently, considerable interest has been directed toward determining ration protein needs of barrows ...
  • Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1986)
    One of the important, recurring decisions that each hog producer must make is the weight at which to sell hogs. The decision to sell hogs may be influenced by cost and availability of feed, anticipated market hog price ...
  • 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 ...
  • Huang, K.; Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1980)
    We used 140 crossbred pigs averaging 30.4 lb to determine phosphorus bioavailability with the slope-ratio technique. A standard curve was established by feeding a basal diet 0% inorganic phosphorus and three levels ...
  • 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 ...
  • Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1977)
    Eighty-four crossbred pigs averaging 43.6 kg. (95.9 lbs.) initially were used to evaluate the use of a blended dried bakery product (BDBP) in rations for finishing pigs. Replacing 0, 10, 20, or 30% of the sorghum in the ...
  • Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1977)
    A growth trial, a digestion trial, and a preference trial were conducted to evaluate a blended dried bakery product (BDBP) as an ingredient in swine starter rations. Replacing 0, 10, 20, or 30% corn with BDBP had no effect ...
  • Allee, G.L.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1974)
    Two trials involving 94 pigs were conducted to evaluate blood meal as a supplemental amino acid source in swine diets. Performance of growing pigs was markedly reduced when blood meal completely replaced soybean meal as ...
  • Kats, L.J.; Weeden, T.L.; Nelssen, Jim L.; Goodband, Robert D.; Tokach, Michael D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1992)
    A total of 144 weanling pigs (initially 14.1 lb and 24 d of age) was used to compare three different blood meal sources in starter diets. The three sources included spray-dried porcine, spray-dried bovine, and flash-dried ...
  • 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 ...
  • Warren, K.E.; Hunt, Melvin C.; Marksberry, C.L.; Sorheim, O.; Kropf, Donald H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Modified atmosphere packaging with 100% carbon dioxide was used to investigate changes in daily gas composition, as well as the influence of fat trim level and location of loin in the box on shelf life characteristics. ...
  • Murphy, James P.; Harner, Joseph P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1995)
    Buildings for early-weaned pigs present several challenges to designers and building/equipment manufacturers, but the ability to provide the optimum environmental conditions for the small pig is within the reach of ...
  • Greer, J.G.; Davis, Duane L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1977)
    Forty-two boars averaging 67 lbs. were used to study how various levels of calcium and phosphorus in their feed affected their development. Calcium-to phosphorus ratios of 1.2 to 1 were maintained in all treatment diets, ...
  • Friesen, K.G.; Boland, Michael A.; Schinckel, A.P.; Nelssen, Jim L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
    Data from two experiments were used to determine the feed cost per I of lean gain for high-lean growth gilts fed various digestible lysine levels (.54 to 1.04%). The cost for producing 1 lb of lean increased as live weight ...
  • Johnston, S.L.; Hines, Robert H.; Traylor, S.L.; Hancock, Joe D.; Behnke, Keith C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1995)
    Growing/finishing gilts were fed two-, three-, four-, or five-phase diet regimens from 77 to 276 lb. The diets were mixed in either a conventional, horizontal ribbon mixer or a 9 ft auger. No interactions occurred among ...
  • Kropf, Donald H.; Bergkamp, J.L.; Berroth, J.N. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1969)
    This study compared various methods of evaluating carcasses. Data from 57 barrows on feeding trials for a barrow contest at the 1968 Kansas State Fair in Hutchinson were used.The barrows went on test weighing approximately ...
  • Elliott, B.D.; Langemeier, Michael R.; Featherstone, Allen M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
