  • Chenoweth, P.J.; Smith, J.F. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Natural service (NS) bulls are widely used on large dairy farms despite the wellproven genetic progress achievable through AI. Producers may choose to use NS bulls for a variety of reasons that are discussed below. ...
  • Ortiz, O.; Heath, J. J.; Orrego, R.; Nelson, R. J.; Garrett, Karen A. (2004)
    Farmer field school programs incorporating farmer participatory research (FPR-FFS) have the potential to provide important benefits to their participants and to other farmers who benefit from improved cultivars and management ...
  • Greene, G.L.; Cilek, J.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    During 1992, adult stable fly populations were sampled in 25 Kansas feedlots. A native stable fly parasitic wasp, Spalangia nigroaenea, was released in 19 of these feedlots. Stable fly populations were reduced up to ...
  • Simon, M.; Keay, L.E.; Kiracofe, G.; Riley, Jack G. (Kansas State University. Agricultural Experiment Station, 1983)
    Heifers that were 167 days pregnant when slaughtered gained faster and more efficiently than open heifers, or heifers that had been aborted with a prostaglandin analog at 83 or 138 days, unless the slaughter weight was ...
  • Neill, S.; Marston, T.T.; Daniel, M.J.; Higgins, James J.; Unruh, John A.; Dikeman, Michael E.; Hunt, Melvin C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    Approximately 16% of cattle slaughtered in the United States are cows. When these cows are removed from the herd, they are typically in thin condition. Steaks from these cows are considered tougher than those from young ...
  • Smith, J.F.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1995)
    Despite the negative effects of milk production on some reproductive traits, calving intervals between high- and low-producing groups varied by only 9 days (414 vs 423). First-service conception rates were 8 ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 1995)
    Reduced milk prices and greater feed costs dictate that dairy farmers carefully manage their nutrition program in order to maintain profitable milk production. Reducing feed cost by feeding less will result in lower ...
  • Schalles, R.R.; Martin, L.C.; Zoellner, K.O. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    In a computer simulation based on KSU data, cattle bred and managed to be moved directly from weaning to feedlot and slaughtered at a young age produced the greatest profit. Cattle that were too small or too large and ...
  • Schlegel, Alan J.; Stone, Loyd R.; Dumler, Troy J.; Lamm, Freddie R. (2012)
    Many of the irrigation systems today in the U.S. Central Great Plains no longer have the capacity to match peak irrigation needs during the summer and must rely on soil water reserves to buffer the crop from water stress. ...
  • Schalles, R.R.; Zoellner, K.O.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Fast-growth genotype steers placed on a high energy ration a month after weaning were compared to a slow-growth genotype on a growing ration for 155 days, followed by a finishing ration for 62 days. The fast-growth ...
  • Shirley, John E. (Kansas Agricultural Experiment Station, 1994)
    The primary focus of the dairy industry in Kansas has been the milking herd. However, dairy heifer replacements and dairy steers offer income opportunities that have been largely ignored by some Kansas dairy producers. ...
  • 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 ...
  • Shirley, John E. (Kansas Agricultural Experiment Station, 1988)
    Progress in the dairy industry over the past 30 yr can be defined as a movement toward fewer farms, more cows per farm, fewer total cows, more milk per cow, a gradual decline in total annual milk production from 1950 ...
  • Shirley, John E. (Kansas Agricultural Experiment Station, 1990)
    The decade of the 1980s was a transition period for the Dairy Industry in the United States. The decade began with a large milk surplus and low prices and ended with milk shortages and record high prices. The dairy ...
  • Dunham, James R. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1997)
    Comfortable cows are contented cows. However, cows may be comfortable in their environment but also experience some discomfort because of the nutrition program. A good nutritional management program will improve ...
  • Dean Bark, L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1985)
    The charts of the daily weather drawn by the KSU computer indicate what occurred in the past two years. The three smooth curves in each diagram represent the average conditions at Manhattan based on 70 years of records ...
  • Bark, L.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1986)
    The charts that follow show graphically the daily weather in Manhattan during the last 2 years. Each chart has three smooth curves to represent the average weather conditions at Manhattan based on 70 years of records ...
  • 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 ...
  • Strahm, T.D.; Harner, Joseph P.; Key, David V.; Murphy, James P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Nine primar,y lagoons and solids storage basins were sampled on Kansas dairies using flush systems. These samples were analyzed for nutrient content of wastewater and sand manure. The manure moisture content in ...
  • 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. ...
