  • 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, ...
  • Smith, J.F.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Mastitis is the most costly health concern in the dairy industry today. Annual losses have been estimated at $180 to 185 per cow. Based on this figure, annual losses for Kansas producers may exceed $15 million. Nationally, ...
  • Vargas, G.; Michaud, J. P.; Nechols, James R. (2012)
    We followed lifetime trajectories of reproductive allocation in Coleomegilla maculata females of three different size classes produced by rearing beetles on three different daily larval feeding regimes (30 min, 6h or ad ...
  • 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 ...
  • White, Bradley J.; Larson, Robert L.; Thomson, Daniel U. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Bovine viral diarrhea virus (BVDv) is an immunosuppressive virus affecting cattle in a multitude of ways. The varied presentation makes this disease difficult to identify in cow herds and the signs of a BVD infection ...
  • Mancini, R.A.; Hunt, Melvin C.; Kropf, Donald H.; Hachmeister, K.A.; Johnson, D.E.; Fox, Sean (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    This study evaluated the combined effects of storage temperature, storage time, display temperature, display time, and fat level on ground beef color. Storage at 32°F minimized discoloration during display compared ...
  • 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 ...
  • Aubel, C.E. (Kansas Agricultural Experiment Station, 1955)
    This experiment was designed .to secure information on maximum use of alfalfa meal in protein supplemental mixtures for pigs in dry lot. The experiment on next page reports similar information from pigs on alfalfa ...
  • Aubel, C.E. (Kansas Agricultural Experiment Station, 1956)
    Since pastures for swine are often poor, inadequate, or unavailable in Kansas, there is a growing appreciation of the value of alfalfa hay or meal in the rations of all swine brood sows (and pigs being fed for market). ...
  • 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, ...
  • Bremer, Dale J.; Ham, Jay M. (2002)
    Soil-surface CO2 flux (R[subscript]s), which is a large component of the carbon (C) budgets in grasslands, usually is measured infrequently using static or dynamic chambers. Therefore, to quantify annual C budgets, estimates ...
  • Bremer, Dale J.; Ham, Jay M. (2005)
    Field measurements of photosynthesis in turfgrass often are conducted with handheld chambers that are temporarily placed over the canopy and soil. Because gas exchange measurements include soil respiration (R [subscript]s), ...
  • Goll, S.J.; Kastner, Curtis L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    The dried weight of the material washed from meat surfaces by distilled water closely paralleled the binding strength between meat particles as measured by tensile strength testing. Sponges added to meat pieces during ...
  • Predicala, B.Z.; Maghirang, Ronaldo G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Methods for measuring concentrations and emission rates of particulate matter (PM) from mechanically ventilated livestock buildings were evaluated in a laboratory facility and in a swine-finishing barn. Concentrations of ...
  • Langemeier, Michael R.; Jones, R.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    This study evaluated scope efficiency (the degree of efficiency gained from producing more than one product within the same farm) for a sample of crop and beef farms in Kansas. Scope and economic efficiency were estimated ...
  • Boland, Michael A.; Crespi, John M.; Silva, Jena; Xia, Tian (2012)
    This paper determines the benefits and costs of firm-level advertising in a monopolistically competitive industry. The model is useful in an environment in which firm-level costs may be absent or imprecise. The empirical ...
  • Langemeier, Michael R.; Jones, R.; Kuhl, G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    This study examined improvements in the finishing performance of steers and heifers from 1990 to 1998 by measuring the rate of technological change. The rates of technological change were 0.58% per year for finishing ...
  • Leising, J.; Tuma, H. (Kansas State University. Agricultural Experiment Station, 1972)
    Meat shrinkage is a major problem for the beef industry. Shrinkage (loss in weight) results from many factors: improper chilling, low humidity, not packaging, poor sanitation, or excessive ageing time. Most beef is chilled ...
  • Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1970)
    Various types of mechanical units designed to replace lactating brood sows are available. The Mini-Mor Corporation, Omaha, Nebraska, lent Kansas State University a unit designed to raise 36 pigs in individual cages. We ...
  • Burson, D.E.; Hayward, L.H.; Hunt, Melvin C.; Kastner, Curtis L.; Kropf, Donald H. (Kansas State University. Agricultural Experiment Station, 1979)
    We randomly assigned 112 Angus yearling steers to 14 nutritional groups fed varied ration energy levels and varied lengths of time. Blade tenderized and non-tenderized boneless rib steaks were evaluated by a taste panel ...
