    Dairy cow herd enterprise records from Kansas Farm Management Association farms over the past 4 years have shown an increase in returns to labor and management from $252 to $355 per cow. Returns for higher milkproducing cows ...
  • Morrill, J.L. (Kansas Agricultural Experiment Station, 1986)
    Proper nutrition and management are necessary to provide adequate numbers of healthy herd replacements. Satisfactory heifer programs must take into consideration care of the dam and characteristics of the newborn calf, ...
  • Portaluppi, M.A.; Tenhouse, D.E.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Our objective was to determine whether delaying the PGF2α injection by 24 or 48 hr after the first GnRH injection in an Ovsynch protocol (from a standard 7 days) altered ovar-ian characteristics in lactating dairy cows. ...
  • Tenhouse, D.E.; Krisher, R.L.; Lamb, G.C.; Dahlen, C.R.; Larson, J.E.; Pursley, J.R.; Bello, Nora M.; Fricke, P.M.; Wiltbank, M.C.; Brusveen, D.J.; Burkhart, M.; Youngquist, R.S.; Garverick, H.A.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Our objective was to determine accuracy of identifying anovulatory lactating dairy cows before the application of a timed AI protocol [with or without progesterone supplementation via a controlled internal drug release ...
  • VanBaale, M. J.; Scheffel, Michael V.; Titgemeyer, Evan C.; Lindquist, R.U.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Twenty-four multiparous Holstein cows were used in six 4×4 Latin squares with 28- day periods to determine inclusion rates for wet corn gluten feed (WCGF) in diets for lactating dairy cows. Cows were housed in a tie-stall ...
  • Smith, J.F.; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    Metabolic disorders and related health problems are a significant problem on dairy farms, resulting in increased culling and decreased profitability for producers. Early detection and treatment of disorders and disease is ...
  • Greer, J.; Rozell, Timothy G. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1997)
    A possible alternative to conventional castration methods is the use of vaccines that can be injected in order to sterilize animals. One promising approach involves the use of a vaccine that causes cattle to produce an ...
  • Morrill, J.L.; Dayton, A.D.; Zmolek, A.J.; Vitcenda, M.A. (Kansas Agricultural Experiment Station, 1984)
    After preliminary experiments, four trials were conducted to develop and test a new feeding program for calves. The program involves the use of a special feed (a prestarter) to encourage calves to eat dry feed and to ...
  • Smith, M.W; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1994)
    Holstein cows and virgin heifers were treated with progestins and PGF before first 2a service to determine their influence on reproductive traits. Control cows were given two injections of PGF 14 days apart and ...

    Four ruminally cannulated and two intact multiparous Holstein cows were used in a 3 × 3 replicated Latin square design to evaluate digestibility and rumen traits in lactating dairy cows in response to feeding wet corn ...
  • Bradford, Barry J.; Titgemeyer, Evan C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    Milk fat depression remains a problem on dairy farms, and in recent years, incorporation of distillers grains (typically with solubles added and often dried) has contributed to this problem on some farms. In this study, ...
  • Titgemeyer, Evan C.; Bradford, Barry J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    Molasses has long been used in animal feeds for palatability and as a binding agent to ensure uniform consumption of essential nutrients. Recent work with molasses in highly fermentable diets has revealed that molasses ...
  • Schulte, K.M.; Dhuyvetter, Kevin C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2009)
    The financial bottom line, or net income, is a key factor in determining how successful a dairy has been historically as well as an indicator of the financial ease or struggles the dairy might have in the future. What ...
