  • Campbell, C.G.; Milton, C.T.; Titgemeyer, Evan C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-10)
    One hundred British and British cross steers, averaging 631 lb ( initial wt) were used in a growing and finishing study to evaluate the effects of unprotected amino acid supplementation on cattle performance and carcass ...
  • Liu, Zifei; Powers, W. J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2014-05-09)
    Ammonia (NH3) and hydrogen sulfide (H2S) emissions from swine production facilities receive considerable attention due to human health and environmental implications. Accurate quantification of farm emissions is essential ...
  • Hijaz, F.; Smith, J. Scott; Kastner, Curtis L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-01-22)
    Anhydrous ammonia is used as a refrigerant in large warehouses for cooling meats, fruits, vegetables, milk, and other products. Ammonia offers several advantages over other refrigerants; it does not harm the ozone layer ...
  • Andries, K.M.; Schalles, R.R.; Franke, D.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-05)
    Data from a rotational crossbreeding study was used to calculate among-breed heritabilities of birth weight (BWT), weaning weight (WWT), and mature cow weight at 5 years of age. The among-breed estimates were higher ...
  • Andries, K.M.; Schalles, R.R.; Franke, D.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-17)
    Data from a rotational crossbreeding study was used to calculate among-breed heritabilities of birth weight (BWT), weaning weight (WWT), and mature cow weight at 5 years of age. The among-breed estimates were higher ...
  • Pickett, A.G.; Smith, E.F. (Kansas Agricultural Experiment Station, 2012-01-25)
    One hundred thirty-five yearling steers which had been wintered as calves at Guymon, Oklahoma, on short grass, sorghum bundles, prairie hay and cottonseed cake, were, furnished to Kansas State College by the Robbins ...
  • McCluskey, Kevin; Parsons, J. P.; Quach, K.; Duke, C. S.
    While living collections are critical for biological research, support for these foundational infrastructure elements is inconsistent, which makes quality control, regulatory compliance, and reproducibility difficult. In ...
  • Zhu, L.; Jones, Cassandra K.; Guo, Q.; Lewis, L.; Stark, Charles R.; Alavi, Sajid
    The quantification of total starch content (TS) or degree of starch gelatinization (DG) in animal feed is always challenging because of the potential interference from other ingredients. In this study, the differences in ...
  • Gonalves, M. A. D.; Bello, Nora M.; Dritz, Steven S.; Tokach, Michael D.; DeRouchey, Joel M.; Woodworth, Jason C.; Goodband, Robert D.
    Advanced methods for dose-response assessments are used to estimate the minimum concentrations of a nutrient that maximizes a given outcome of interest, thereby determining nutritional requirements for optimal performance. ...
  • Barandoc-Alviar, K.; Ramirez, G. M.; Rotenberg, Dorith; Whitfield, Anna E.
    The corn planthopper, Peregrinus maidis (Ashmead) (Hemiptera: Delphacidae), transmits Maize mosaic rhabdovirus (MMV), an important pathogen of maize and sorghum, in a persistent propagative manner. To better understand the ...
  • Langemeier, Michael R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-15)
    Estimated historical return distributions for farrow-to-finish, feeder pig finishing, and feeder pig producing operations in Kansas from 1981-1990 were examined. Average returns per head were the highest and downside risk ...

    Bread wheat (Triticum aestivum) is a globally important crop, accounting for 20 per cent of the calories consumed by humans. Major efforts are underway worldwide to increase wheat production by extending genetic diversity ...
  • Perry, R.C; Simms, D.D.; Corah, L.R.; Patterson, D.J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-06)
    A data set of 33,208 individual weaning records (1968-1985) from producers within Kansas was analyzed to determine factors influencing weaning weight. In determining the effect of calving sequence (21 day periods), only ...
  • Yujie, Lu; Beeman, Richard W.; Campbell, James F.; Park, Yoonseong; Aikins, Michael J.; Mori, Kenji; Akasaka, Kazuaki; Tamogami, Shigeyuki; Phillips, Thomas W. (2011-10-19)
    We report that the abdominal epidermis and associated tissues are the predominant sources of male-produced pheromones in the red flour beetle, Tribolium castaneum and, for the first time, describe the stereoisomeric ...
  • Cartmill, J.A.; Zarkouny, S.E.; Hensley; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-03)
    The incidence of anestrus in dairy cattle prior to first inseminations carried out after a minimum of 60 days postpartum ranged from 4 to 58% in first-lactation cows and 14 to 50% in older cows. Dairy cows with more days ...
  • Wilson, R.W. (Kansas Agricultural Experiment Station, 2012-09-20)
    The makers of the laws, rules, and regulations governing the production and processing of milk have recognized that milk is the primary diet of the very young and old. This fact mandates that it should be produced and ...
  • Menzies, C.S. (Kansas Agricultural Experiment Station, 2011-04-28)
    Animal fats often are added in small amounts (1-2%) to mixed commercial feeds primarily to reduce dustiness and to lubricate machinery. High-energy poultry rations often contain higher levels of animal fat. This test was ...

  • Chestnut, A.; Brent, B.E. (Kansas State University. Agricultural Experiment Station, 2011-03-04)
    We are developing mathematical models to show how feed intake, rate of gain, and feed efficiency change during the finishing period. When finished, the models might be used to predict when to sell cattle to maximize profit ...
