  • A review of oxytocin use for sows and gilts
    Linneen, S.K.; Benz, J.M.; Dritz, S.S.; DeRouchey, J.M.; Goodband, R.D.; Tokach, M.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2005)
    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 ...
  • Round bale alfalfa processing method affects heifer growth but does not influence wastage or eating preference
    Jones, S.Q.; DeRouchey, J.M.; Waggoner, J.W.; Marston, T.T.; Breiner, R.M.; Kraus, T.J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010)
    Many factors affect forage quality, including moisture level at baling, compaction, bulk density, and maturity at harvest. Losses of dry matter and nutrient value occur during field curing. Hay baled at or above 18% ...
  • Round bale alfalfa processing method does not influence feeding or mixing characteristics in a total mixed ration
    Jones, S.Q.; DeRouchey, J.M.; Waggoner, J.W.; Marston, T.T.; Breiner, R.M.; Kraus, T.J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010)
    Nutritionists and producers often assume that ingredients in a total mixed ration are uniformly mixed. However, many factors may affect ration homogeneity, including particle size, shape, and density and mixer discharge ...
  • Sensory characteristics of loins from pigs fed glycerol and ractopamine HCl during the last 28 days of finishing
    Duttlinger, A.W.; Houser, T.A.; DeRouchey, J.M.; Tokach, M.D.; Dritz, S.S.; Nelssen, J.L.; Goodband, R.D.; Prusa, K.J.; Huskey, L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    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 ...
  • Sucrose and molasses in simple or complex diets for nursery pigs
    Mavromlichalis, I.; Hancock, J.D.; Hines, R.H.; DeRouchey, J.M.; Senne, B.W.; Sorrell, S.P.; Cao, H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Three experiments were conducted to determine the effects of replacing lactose with sucrose and molasses in simple and complex diets for nursery pigs. In general, complex diets supported greater growth performance than ...
  • Use of dried distillers grains with solubles and soybean hulls in nursery pig diets
    Barbosa, F.F.; Dritz, S.S.; Tokach, M.D.; DeRouchey, J.M.; Goodband, R.D.; Nelssen, J.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    A total of 3,186 pigs were used in two 21-d experiments to evaluate growth performance of nursery pigs fed different levels of dried distillers grains with soluble (DDGS) or soybean hulls. In each experiment, pigs (n = ...
  • Use of dried distiller’s grains with soluble for swine diets
    Hastad, C.W.; Tokach, M.D.; Nelssen, J.L.; Goodband, R.D.; Dritz, S.S.; DeRouchey, J.M.; Groesbeck, C.N.; Lawrence, K.R.; Lenehan, N.A.; Keegan, T.P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    A large increase in the number of ethanol plants has lead to increased availability of dried distiller’s grains with solubles (DDGS). New plants also have improved processing techniques, which makes DDGS more attractive ...
  • Using heart girth to determine weight in finishing pigs
    Groesbeck, C.N.; Goodband, R.D.; DeRouchey, J.M.; Tokach, M.D.; Dritz, S.S.; Nelssen, J.L.; Lawrence, K.R.; Young, M.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Heart girth and body weight were measured on 100 growing-finishing pigs (50 to 273 lb) at the KSU Swine Teaching and Research Center. Heart girth, in inches, was measured using a cloth measuring tape. The tape was placed ...
  • Validation of control diets for lactose and fish meal replacement studies in nursery pigs
    Sulabo, R.C.; Tokach, M.D.; DeRouchey, J.M.; Goodband, R.D.; Dritz, S.S.; Nelssen, J.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    The objective of this study was to develop and validate control test diets to be used for lactose and fish meal replacement studies in nursery pigs. A total of 180 nursery pigs (PIC, initially 16.6 lb and 28 ± 2 d of age) ...
  • Validation of flank-to-flank measurements for predicting boar weight
    Sulabo, R.C.; Quackenbush, J.; Goodband, R.D.; Tokach, M.D.; Dritz, S.S.; DeRouchey, J.M.; Nelssen, J.L (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Allometric relationships, in which linear body dimensions are expressed as a function of body weight, are commonly used in growth studies. Previous work at Kansas State University showed a positive correlation between ...
  • Variation in chemical composition of soybean hulls
    Barbosa, F.F.; Tokach, M.D.; DeRouchey, J.M.; Goodband, R.D.; Nelssen, J.L.; Dritz, S.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    The objective of this study was to examine the variation in chemical composition of soybean hulls. Our goal was to develop regression equations characterizing the nutritive value of soybean hulls for use in swine diets. ...
  • Variation in the digestiility of amino acids in soybean meal from a single processing plant
    Lee, D.J.; Hancock, J.D.; DeRouchey, J.M.; Maloney, C.A.; Dean, D.W.; Cao, H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Digestibilities of amino acids among samples of soybean meal (SBM) collected during a fall harvest season (4 collections made 15 d apart) were similar, except that true digestibility from tryptophan was lower for a sample ...
