    The influence of cow weight at parturition and during the lactation on preweaning performance of calves was evaluated. Hereford cattle at the Fort Hays Branch Experiment Station were used. Purebred sires had been used ...
  • Call, Edward P.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 2012-09-20)
    Cow-side milk progesterone tests are effective in determining the presence of an active corpus luteum (CL) on the ovary. The test is best used as an adjunct to the Preventive Herd Health Program (PHHP) as a means of ...
  • Simms, D.D.; Marston, T.T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-02)
    Cost/return analyses of 56 Kansas cow/calf operations were summarized to determine the major factors influencing 1987 and 1988 cow herd profitability. Gross returns and costs on a per cow unit basis were extremely variable. ...
  • Blecha, Frank; Pollmann, D.S.; VanWormer, D.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-23)
    An experiment was conducted to determine the influence of creep feeding on cellular immunity in young pigs. Creep feeding from 10 days of age to weaning did not influence phytohemagglutinin skin-test responses.

    Crude glycerin is the principal byproduct of biodiesel production. The raw feedstocks, animal fats and vegetable oils, yield approximately 90 lb of biodiesel and 10 lb of crude glycerin for each 100 lb of input. When ...
  • Parsons, G.L.; Shelor, M.K.; Drouillard, James S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009-12-14)
    Plant oils contain large amounts of triglycerides that will react to a catalyst, such as methanol. The transesterification reaction between the oil and alcohol will produce approximately 10% crude glycerin and 90% biodiesel. ...
  • Bolsen, K.; Hinds, M.; Ilg, H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-14)
    Laboratory silos were used in three trials to evaluate sudangrass (slightly or moderately wilted) and high moisture corn silages, each receiving the following treatments: (1) control (no additive); (2) CULBAC® dry; (3) ...
  • Cox, C. M.; Bowden, Robert L.; Fritz, A. K.; Dendy, S. P.; Heer, William F.; Garrett, Karen A. (2012-06-01)

  • Harborth, K.W.; Schulz, L.L.; Dhuyvetter, Kevin C.; Waggoner, Justin W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2011-03-17)
    Today’s tough economic environment for cattle producers makes each decision critically important, and increased knowledge of the link between pricing and genetic, management, and marketing decisions can increase an ...
  • Cheng, Yufeng; Wang, Qian; Li, Zhanjie; Cui, Jianmin; Hu, Shengwu; Zhao, Huixian; Chen, Ming-Shun (2014-02-18)
    Male sterility induced by a chemical hybridization agent (CHA) is an important tool for utilizing crop heterosis. Monosulphuron ester sodium (MES), a new acetolactate synthase-inhibitor herbicide belonging to the sulphonylurea ...
  • Campbell, C.G.; St. Jean, G.; Titgemeyer, Evan C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-10)
    Increasing the amino acid supply to the small intestine of growing cattle can increase performance, if specific amino acids are limiting. Although this can be accomplished by feeding rumen undegradable protein, a more ...
  • Zhang, Yixing; Vadlani, Praveen V. (2014-01-22)
    Poly-lactic acid (PLA) derived from renewable resources is considered to be a good substitute for petroleum-based plastics. The number of poly L-lactic acid applications is increased by the introduction of a stereocomplex ...
  • Brandt, Robert T., Jr. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-22)
    One hundred sixty-five crossbred steers averaging 823 lb were utilized to evaluate the daily or weekly rotational feeding of ionophores. Treatments were (g/ton of feed, 90% dry basis): 1) Bovatec (B; 30), 2) Rumensin ...
