  • Davis, Duane L.; Zhang, Z.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1988)
    We tested the effects of feeding 4 or 7.4 lb of a complete gestation diet to gilts during days 0 to 2 or 3 to 10 after first detected estrus (day 0) and mating. There was a tendency (P = .11) for the 7.4 lb/day treatment ...
  • Turlington, L.M.; Corah, L.R.; Allen, Dell M.; Nelssen, Jim L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1986)
    Determination of backfat thickness and loin-eye area in swine is essential for continued genetic progress, and ultimately, pork product acceptance. Leaner, faster growing boars and gilts must be provided by seedstock ...
  • Murphy, James P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1988)
    Low investment farrowing facilities can be divided into three categories, depending on the level of investment. At the lowest investment level, an individual farrowing shelter that has no floor is utilized. The shelter ...
  • Musser, R.E.; Kerr, C.A.; Richert, B.T.; Goodband, Robert D.; Nelssen, Jim L.; Tokach, Michael D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    A total of 150 pigs was used to evaluate the effects of corn with different crude protein content on growth performance of finishing pigs. Our objective was to determine if low protein corn might result in poorer pig ...
  • Hansen, J.A.; Thaler, R.C.; Goodband, Robert D.; Nelssen, Jim L.; Hines, Robert H.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Two growth studies were conducted to determine the effects of substituting lower test-weight sorghum (35 lb/bu as LOW or 45 lb/bu as MED) for normal test-weight sorghum (55 lb/bu NORM), in growing and finishing swine diets. ...
  • Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1969)
    The new K-State facilities for growing-finishing swine seemed ideal to re-evaluate various antibiotics as low-level feed additives. The first trial reported here was with the first pigs fed in the new barn. They also were ...
  • Mavromichalis, I.; Kim, I.H.; Burnham, L.L.; Rantanen, M.M.; Hines, Robert H.; Hancock, Joe D.; Kropf, Donald H.; Behnke, Keith C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1995)
    Partially omitting (up to 66 %) the supplemental inorganic phosphorus (P) source from a late-finishing (190 to 250 lb) diet resulted in slightly greater ADG and backfat thickness, which probably resulted from the greater ...
  • Pollmann, D.S.; Allee, G.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    A total of 943 newly weaned (18 to 30 days of age) pigs were used in five trials to evaluate the addition of lysine and dried whey in starter diets. The results of these studies show that the lysine requirement is 1.2 to ...
  • Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1969)
    The protein level and protein quality of swine rations consisting primarily of grain can be changed by adding either protein like soybean meal or individual amino acids like lysine. Protein requirements are based on ...
  • Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1973)
    Four experiments involving 311 finishing pigs (112 to 220 pounds) were conducted to determine the minimum level of soybean meal necessary to supply all essential amino acids except lysine that are deficient in milo or ...
  • Ferrell, K.C.; Allee, G.L.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1974)
    Feeding trials involving each sex (boars, barrows and gilts) of finishing-weight pigs were conducted to determine the value of adding lysine to the rations. Rations containing 0.55% lysine were adequate for performance ...
  • Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1978)
    Successful swine producers pay careful attention to the breeding herd. The members of our producer panel will present three approaches to managing reproduction. Their ideas are of particular interest since each is a ...
  • Jones, C.L.; Starkey, C.W.; Hancock, Joe D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    A total of 168 pigs (average initial BW of 13.2 lb and avg initial age of 21 d) was used in a 35-d experiment to determine the effects of mannanoligosaccharides on growth performance of nursery pigs fed diets without ...
  • Keeler, G.L.; DeRouchey, Joel M.; Goodband, Robert D.; Nelssen, Jim L.; Tokach, Michael D.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Analysis of 41 manure samples from Kansas swine lagoons revealed that nutrient concentrations were higher than previously reported values from the Nebraska Cooperative Extension Service and the Midwest Planning Service. ...
  • Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Finishing pig diets are commonly supplemented with copper, zinc, iron, and manganese with large margins of safety compared to those suggested by NRC requirements. In this study, pigs were fed a control diet that provided ...
  • Schroeder, Ted C.; Mintert, J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Cash hog markets are declining in importance, and use of formula pricing of market hogs is increasing. Producers need more information to assist them in price discovery and formula price negotiations with pork packers. ...
  • Dhuyvetter, Kevin C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    A formula for deriving the price of segregated early-weaned (SEW) pigs using prices of grain, soybean meal, and market hog was estimated based on return on investment being equal for all three phases of production—farrowing, ...
  • Groothuis, P.G.; Blair, R.M.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1995)
    We determined the age at which progesterone induced certain responses in the gilt's uterus. The prepubertal maturation permitting each response is being studied currently with the intent of using the information to develop ...
  • Levis, D.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Farrowing rate can be defined as: 1) the number of mated females that farrow within a contemporary group per total number of MATED females for this group or 2) the number of females that farrow within a contemporary group ...
  • 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, ...
