  • Intake and performance of dairy cows fed wet corn gluten feed during the periparturient period
    Park, A.F.; Defrain, J.M.; Meyer, M.J.; Shirley, J.E.; Titgemeyer, E.C.; Marston, T.T.; Gleghorn, J.F.; Wankel, L.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Eight primiparous and nine multiparous Holstein cows were used in a randomized block design to determine the effect of wet corn gluten feed in the diet during the last 21 days of gestation on dry matter intake and early ...
  • Keeping cows cool
    Smith, J.F.; Harner, J.P.; Brouk, M.J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Heat stress occurs when a dairy cow’s internal heat load is greater than her capacity to lose unwanted heat to the environment. Effects of heat stress include: increased respiration rate, increased water intake, ...
  • Manure and lagoon nutrients from dairies using flush systems
    Strahm, T.D.; Harner, J.P.; Key, D.V.; Murphy, J.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 ...
  • Mastitis management-effective methods to reduce somatic cell counts
    Brouk, M.J.; Smith, J.F. (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, ...
  • Monensin: an overview of its application in lactating dairy cow diets
    DeFrain, J.M.; Shirley, J.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    The efficiency of feedstuff utilization by ruminal microorganisms and the cow’s genetic ability to convert feed nutrients into milk and milk components are major factors that influence the profitability of a dairy herd. ...
  • Raw milk quality: the processor's point of view
    Schmidt, K.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Raw milk quality is important to the processor for many reasons, this quality can be assessed by several different tests. Quality tests are used to ensure that the raw milk meets legal USDA standards as well as some of ...
  • Relationship among concentrations of milk urea nitrogen and plasma urea nitrogen and feeding time
    Ferdinand, E.E.; Shirley, J.E.; Meyer, M.J.; Park, A.F.; VanBaale, M.J.; Titgemeyer, E.C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Eight Holstein cows were used to determine the relationship among milk urea nitrogen (MUN), plasma urea nitrogen (PUN), and feeding time. We first established that MUN concentrations were similar in concentration among ...
  • Salmonella Dublin: a threat to dairy heifer survival and future performance
    Schmidt, D.G.; Gnad, D.P.; Sargeant, J.M.; Shirley, J.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Salmonella dublin is a bacterium that can have devastating effects in dairy herds. It is most deadly with calves that range in age from 10 days to 5 months. Salmonella dublin is shed from carrier animals through feces, ...
  • Silage Management: important practices often overlooked
    Bolsen, K.K.; Brent, B.E.; Siefers, M.K.; Uriarte, M.E.; Schmidt, T.E.; Pope, R.V. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Four important silage management practices that are in the control of livestock producers and that are sometimes poorly implemented or overlooked entirely include: inoculating, packing, sealing, and managing the feedout face.
  • Total blood protein as an indicator of colostral sufficiency and morbidity in dairy calves
    Schmidt, D.G.; Gnad, D.P.; Sargeant, J.M.; Shirley, J.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Total blood protein measured in calves between 1 and 7 days of age is a good indicator of the sufficiency of colostral intake and level of immunity passed to the calf. This measurement can be used to improve calf management ...
